Chapter 167, Fermat's Conjecture HYM Equation First Citibank Check Hell Class
In the auditorium of Princeton University in the United States, Wang Duoyu smiled confidently and answered everyone's questions with ease.

He did not call the names of those who appeared particularly anxious, and did not allow them to ask questions.

Seeing how anxious they were, yet helpless, unable even to get mad with rage, Wang Duoyu felt secretly happy.

If they really get angry and disrupt the normal order of the meeting, they will definitely be asked to leave by the staff.

So they don’t dare to do that at all!

Seeing that twelve o'clock was approaching, Wang Duoyu ignored those people and was about to announce the end of the morning's report meeting and then leave. But at this moment, someone suddenly stood up and roared loudly:

"It's fake. Your paper is all fake. You're guilty and you don't even dare to let me ask questions."

In the auditorium, everyone looked at him with admiration for this brave man.

Wang Duoyu saw the other party jump out, paused, and said: "Okay, you will ask the last question, but please don't waste our time, just ask it yourself."

As expected, when the man heard this, he was overjoyed and immediately wanted to go up to the podium, but was stopped.

This student from the École Normale Supérieure in Paris, France, has gone a little crazy.

The questions asked were exactly as Wang Duoyu expected, which were doubts about the two major tools: L-function and spatial transformation.

After the other party finished speaking, Wang Duoyu immediately smiled and said:

"I don't want to answer this question anymore. I explained it very clearly in my presentation just now. The L-function tool is very clearly explained in the paper. I don't have the obligation to explain it to you in such detail. Perhaps you can go back and ask your advisor. Okay, this concludes the presentation. See you this afternoon."

After that, he put down the microphone and left the auditorium.

Requiring him to answer such a simple question is simply polluting his IQ.

There were a bunch of big guys in the front row, and they all asked very critical questions, so Wang Duoyu would explain them seriously.

After Wang Duoyu sent out the paper in June last year, it was successfully published around the end of August or the beginning of September.

From September last year to July now, a total of about eleven months have passed. If you haven't read and understood these three papers thoroughly by then, you are just here to make up the numbers.

That's why Wang Duoyu doesn't waste his time.

At lunch, Wang Duoyu was invited by Andrei Wei and others to go to the private room to eat and chat quietly.

Andre Weil and others said that Wang Duoyu's report would be very exciting, but it was a pity that not many people could understand it.

During the conversation, Andre Weil asked a question: How did Wang Duoyu manage to enable students like Xue Xiaoling to write such good papers?
As soon as this question was asked, both Shiing-Shen Chern and Shing-Tung Yau could not help but prick up their ears.

Although as Chen Xingshen's identity, his teaching and mathematical abilities are among the best in the world, Wang Duoyu is still so young and a top expert in scientific research, and it is unexpected that he is also so top-notch in teaching.

Every time he looked at Wang Duoyu, Chen Shiing-Shen couldn't help but feel regretful: Why couldn't he accept Wang Duoyu as his student?
If you have to blame someone, you can only blame the wrong timing.

"I didn't do anything. You may have heard that I just taught them a few mathematical tools like the L function, but I didn't do anything else."

Wang Duoyu spread his hands and said:

"I didn't even provide guidance on their papers because I simply didn't have the time. My daily schedule was very tight."

"You don't know, every holiday, I will go back to my hometown to hunt. Do you know that I now have more than 20 animal skins at home, including tigers, wolves, leopards, black bears and other beasts."

"But I still really want to hunt animals with beautiful fur. Those hides are excellent raw materials for making warm gloves, hats, etc."

As they chatted, Wang Duoyu talked about hunting.

Smel and the others were also very interested in this and joined in the conversation.

Happy times always pass quickly. Wang Duoyu politely declined Smel's invitation to go hunting in Alaska, ending the two-hour lunch.

Alaska is a good place, but it's too far away, and I heard there are a lot of rules there.

Even if he hunted some good animal skins, it would be a huge trouble for Wang Duoyu to take them away.

Besides, bringing animal skins back to China from the United States over such a long distance, isn't that crazy?

If you have to bring anything, then you should bring back US dollars or high-tech equipment.

However, Wang Duoyu's identity is destined to make him unsuitable for purchasing equipment such as lithography machines in the United States. Professional matters should be left to professionals.

He is engaged in scientific research, so he should just focus on scientific research and there is no need to take risks.

Soon, the afternoon report will continue.

Wang Duoyu returned to the podium again and began his last report.

The Poincaré conjecture has basically been concluded, and his last lecture was just a formal announcement.

From the time the paper was published last September to now, if there really were any problems, someone would have raised them long ago.

As the hottest topic in mathematics, there are too many researchers studying the Poincaré conjecture.

Many people want to be John Milnor or Sergey Novikov, twisting and turning again.

Unfortunately, the three papers Wang Duoyu produced were impeccable and perfect.

After Wang Duoyu finished his 45-minute report, the entire auditorium burst into applause, which lasted for more than five minutes.

Everyone was very excited because they witnessed history.

The Poincaré conjecture must have a place in the history of mathematics, and Wang Duoyu, who proved this conjecture, will surely be remembered by future generations.

As witnesses, everyone was naturally excited.

"Thank you, thank you everyone. The next fifteen minutes are for questions. Please allow this gentleman to ask his question."

Wang Duoyu smiled and pointed at one of them to ask a question.

In fact, this paper has fewer doubts. After the Poincare conjecture in three-dimensional space was proved this morning, it is enough to show that this conjecture is no longer a conjecture, but an axiomatic theorem.

Although the capping paper is also very complicated, anyone who has understood the two papers on three-dimensional space will naturally be able to understand the capping paper.

So there were no surprises at all. Fifteen minutes passed, the questions were over, and the report meeting came to an end.

This also means that the Poincaré conjecture is no longer a conjecture, but the Poincaré-Smale-Wandou theorem.

The report meeting was over, but no one left.

After the applause ended, Shing-Tung Yau came up and stopped Wang Duoyu who was about to leave and asked a few questions.

The first is the theoretical research on the Langlands concept. Based on the previous paper written by Wang Duoyu and the theoretical connections such as modular form and reciprocity law proposed by Wang Duoyu, Shing-Tung Yau has now made some progress.

He wanted to discuss this with Wang Duoyu at the welcome dinner yesterday.

It’s just that Wang Duoyu was too busy at the time and everyone was around him, so Qiu Chengtong didn’t have a chance to chat with Wang Duoyu.

Now that the report is over, you can speak freely.

When Robert Langlands heard about the Langlands idea, he excitedly went forward to watch.

As the originator of this idea, Robert Langlands certainly wanted to go down in history, but his ability was limited.

If Wang Duoyu and Qiu Chengtong, the two twin stars in the current mathematics world, can advance Langlands's idea, then Robert Langlands will definitely be able to enjoy this part of the "fame".

After listening to this, Wang Duoyu said helplessly:
"Professor Qiu, this is too difficult. I think we should look for other solutions now. Simply advancing the Langlands concept is as difficult as climbing to the sky."

First of all, we need to understand that Langlands' concept is actually to connect number theory, algebraic geometry and reduced group representation theory.

Number theory, algebraic geometry, and group representation theory are three branches of mathematics that have developed relatively independently, but in Langlands' conception, they are closely related.

Just like in the world of physics, Einstein spent his entire life trying to unify gravity and electromagnetic force to form a grand unified theory.

By the same token, Langlands' idea is to prove that number theory, algebraic geometry, and group representation theory are the grand unified theories of mathematics.

Therefore, you can imagine how difficult it is.

Wang Duoyu was writing on the blackboard while saying:
"The linear space of all modular forms is denoted by Mk(Г), which is a finite-dimensional vector space over the complex field. So Gk(z) is a holomorphic function on h, and it can be proved that Gk(z) belongs to M2k(Г)."

"Gk(z) is called the Eisenstein series, and its Fourier expansion at ∞."

Shing-Tung Yau, Robert Langlands, John Milnor and others watched and listened attentively, sometimes frowning and sometimes smiling, obviously following Wang Duoyu's ideas.

But everyone else in the audience was completely bewildered: What was Wang Duoyu talking about? What were these symbols he was writing?

Zhu Chengwu, Xue Xiaoling, Rong Guangxia and others probably heard some of it, but they didn't understand more than 85% of it.

Several old men including Shiing-Shen Chern and André Weil were whispering to each other: Will Wang Duoyu's next research direction be the Langlands concept?

Although this is not a big hit, it seems to be pretty good.

Anyway, it is really awesome. After all, to form a grand unified theory of number theory, algebraic geometry, and group representation theory is certainly a huge project. How can it be that simple?

Soon, when Wang Duoyu had finished speaking, Qiu Chengtong asked:

"So your next research direction is Fermat's Last Theorem?"

As soon as these words were spoken, many people's eyes suddenly lit up, while even more people felt their anus tighten and their faces showed fear.

Why are some happy while others are sad?

Because people like Shiing-Shen Chern and some people who are not researching Fermat's Last Theorem are naturally very happy.

After all, Wang Duoyu has already inclined to study Fermat's Last Theorem, so in the short term, he will definitely be stuck in this subject area and will not explore other fields.

With Wang Duoyu's brain, if he were to act on any theory, he would definitely be quick, accurate and ruthless.

Isn’t the Poincaré conjecture awesome enough?
After Smale in 1961, no one had been able to push the Poincaré conjecture any further. However, Wang Duoyu emerged in 1978 and finally put an end to the Poincaré conjecture in June last year.

Turning a conjecture into a theorem is enough to show how awesome Wang Duoyu is.

Those who are worried are naturally because they are currently studying Fermat's Last Theorem.

Fermat's Last Theorem was proposed as a theorem by French mathematician Pierre Fermat around 1637. Fermat stated the proposition in the margin of Diophantus's Arithmetic and claimed that he had proved it, but his proof did not fit on the blank page.

Moreover, Fermat's Last Theorem was difficult to prove at the time, and Fermat's so-called proof was not recognized, so this should be a Fermat conjecture rather than a theorem.

Leonhard Euler, Legendre, Dirichlet, Sophie Germain and others all tried very hard to prove Fermat's Last Theorem, but none of them could successfully prove it.

Euler gave a proof of p=3, Legendre and Dirichlet independently proved p=5, and Sophie Germain made a breakthrough in the case of a class of prime numbers.

In 1955, Japanese mathematicians Goro Shimura and Yutaka Taniyama observed that there might be a connection between elliptic curves and modular forms, two seemingly completely different branches of mathematics, which is called the Taniyama-Shimura conjecture.

To this day, Fermat's Last Theorem has not been proven.

However, Taniyama Yutaka and Shimura Goro still provided direction and advanced the research progress of Fermat's conjecture.

It’s a pity that there have been no significant achievements in the past few years.

From the above, we can see that Fermat's Last Theorem, or Fermat's Conjecture, is also one of the more popular scientific research topics in the mathematics community, but its difficulty coefficient is greater.

Because even the god of mathematics Euler was involved, and many famous mathematicians were also involved, but none of them proved the Fermat conjecture.

Hundreds of years later, Fermat's conjecture still exists.

Those arrogant mathematics professors and doctoral students, each of them was very arrogant and conceited, but once they stepped into Fermat's conjecture, they were stuck in the quagmire and could never get out.

"Well, I do have such an idea, but I'm a little busy recently, so I may not be able to act so quickly."

Wang Duoyu said honestly.

Promoting the development of Langlands's concept was a goal he had set before, because this was purely theoretical research and was a "smoke screen" he used to confuse others.

If we want to promote the development of Langlands' idea, then proving Fermat's conjecture is inevitable and is the most powerful support for the former.

Why do you say that?

It should be noted that elliptic curves are geometric objects with profound arithmetic properties, while modular forms are highly periodic functions from the completely different field of mathematical analysis. Langlands's conception proposed a network of relationships between Galois representations in number theory and automorphic forms in analysis.

Langlands' idea is to prove the grand unified theory of number theory, algebraic geometry, and group representation theory. The Taniyama-Shimura conjecture among Fermat's conjectures, once proved, will reveal the relationship between elliptic curves and modular forms.

It's that simple.

Upon hearing this, Qiu Chengtong immediately said with a smile:

"Then you better hurry up. I'm sure you won't get there first this time."

As a mathematics professor at Berkeley and a strong contender for the Fields Medal two years later, Shing-Tung Yau is also a very proud person.

But before, when he was trying to verify the Poincare conjecture in three-dimensional space, he had already been defeated by Wang Duoyu.

This time, he will definitely give his all and will not let Wang Duoyu take the lead again.

The damn desire to win between men is just that simple.

When the mathematics professors and PhDs who were working on Fermat's Last Theorem heard what Shing-Tung Yau said, they felt dizzy and almost fainted.

Are the twin stars of mathematics working together to study Fermat's conjecture?
Everyone feels that the future is bleak, so they decide to change careers as soon as possible.

No one dares to underestimate Shing-Tung Yau. Although he was previously at a disadvantage in proving the Poincare conjecture, he is extremely strong and has achieved many research results in recent years.

So we should find a solution as soon as possible. The twins will study Fermat's conjecture together, and it will probably become a theorem soon.

"Okay, then I'll wait and see!" Wang Duoyu said with a smile, but Qiu Chengtong did not continue this topic, but mentioned other topics.

The second topic is related to the HYM equation, which is an important equation in complex geometry and has wide applications in physics and mathematics.

The HYM equation describes the curvature form of a vector bundle with a Hermitian metric on a complex manifold, and is closely related to gauge field theory in physics.

"When the Planck constant approaches zero, how do we describe the relationship between classical mechanics and quantum mechanics?"

I saw Shing-Tung Yau writing and drawing on the blackboard, and various mathematical symbols were written out.

Wang Duoyu is very good at mathematics, but relatively weak in physics.

He had previously communicated with physics giants such as Zhao Zhongyao and Qian Xuesen on mechanics, quantum mechanics and other fields. He learned a lot both in pure mathematics and physics.

But, it is still very weak.

Therefore, in addition to giving a report, Wang Duoyu came to the United States to visit Stony Brook University of the State University of New York to meet Yang Zhenning, a big name in the physics world.

Yang Zhenning is the top figure in the field of physics today. At the Solvay Conference to be held in the United States in two years, he will be the person in the center of the first row, which shows how great his status and contribution to physics are.

At this moment, Wang Duoyu was listening very carefully. After all, Qiu Chengtong’s lecture was very good, so he was trying hard to absorb it.

This is also the reason why he is willing to come to Princeton University to give a report, because he cherishes the opportunity of communication and it can indeed help him improve.

"But physicists encounter many difficulties when discussing field theory. This stems from the fact that they don't know how to deal with the spectral analysis of operators on infinite-dimensional manifolds. An important example is ring space, which is the space that brings together all the closed curves on a given manifold. We want to find a spectral analysis on it, which is a very difficult problem."

Yau continued his talk for over half an hour, and Wang Duoyu also shared his thoughts. The two of them chatted away, oblivious to the others. This made Robert Langlands anxious. Why wasn't he continuing his research?

Ugh!
After Wang Duoyu and the other person had finished their conversation, John Milnor interrupted.

At this moment, someone in the auditorium finally couldn't bear it anymore and ran away!
Because I really couldn't understand it and it was very uncomfortable to stay in the auditorium, I decided to just slip away.

"If I remember correctly, spectral analysis on finite-dimensional manifolds is related to classical paths. In infinite-dimensional space, we expect some kind of minimal surface to be related to the partition function that appears in quantum field theory."

After hearing John Milnor's words, Qiu Chengtong paused, and Wang Duoyu also showed a thoughtful expression.

When there is no way to simply deduce the idea of ​​finite-dimensional space to the geometry of infinite-dimensional space, perhaps the geometric conclusions derived from physical intuition are often correct.

But such ideas are often difficult to withstand calculations.

Wang Duoyu's brain was working fast, thinking about the possibilities in this regard, deducing and calculating the situation that John Milnor had just mentioned.

But it was obvious that all this was in vain.

But it doesn’t matter. After all, this is just communication. Everyone has different ideas. Only through such communication can sparks of inspiration be generated.

After communicating with Professor Shing-Tung Yau for about an hour and a half, Wang Duoyu and his friends finally ended the discussion with a sense of reluctance.

Hitzbruch, Sergei Novikov, Lars Valerian and others have already come up. After all, they have been waiting for a long time, and they all want to communicate with Wang Duoyu.

In today's global mathematics community, Wang Duoyu is recognized as a top mathematician.

Although Wang Duoyu's most notable achievement at present is just proving the Poincare conjecture, the papers he previously published in journals such as Annals of Mathematics and Science China Mathematics covered a very wide range of fields.

So everyone wanted to communicate with him, perhaps to generate other ideas or sparks of inspiration.

It was already around four or five in the afternoon. Many people had left the auditorium one after another, but there were still several hundred people left.

Lu Jiaxi, Wu Congxin, Liu Taoshun and others gathered in groups of three or four and talked in low voices. Even Xue Xiaoling, Zhu Chengwu, Rong Guangxia and others were surrounded by many white people.

In fact, the United States still has a condescending attitude towards us in China, especially most doctoral students.

However, because it was a lecture held by Wang Duoyu, and Xue Xiaoling and the others were all Wang Duoyu's students, these American mathematics doctoral students did not act presumptuously, but were humble and polite instead.

Xue Xiaoling and her colleagues have published papers in journals such as the Annals of Mathematics, the Duke Mathematical Journal, and the American Journal of Mathematics. Based on this alone, few of the American mathematics doctoral students who communicated with them were able to do the same.

Therefore, the entire communication process was very smooth.

The conversation continued until around seven in the evening, when it was starting to get dark outside. After all, it was summer, and it didn't get dark so quickly in the northern hemisphere.

But as it got dark, everyone's stomachs started to growl, and they all dispersed one after another.

For the next two days, Wang Duoyu and his colleagues stayed at Princeton University, communicating with many mathematics professors and researchers.

There were indeed many people who came from all over the world to attend the lecture at Princeton University in the United States, including many famous professors.

For Wang Duoyu, the biggest gain was probably the topics he discussed with Shing-Tung Yau and others.

Fermat's conjecture is a great topic, and Wang Duoyu plans to work on it after returning to Harbin Institute of Technology.

I wonder if Shing-Tung Yau will take the lead?
It was not until the fourth day, after the exchange, that Wang Duoyu finally had time to go to Stony Brook University to meet Yang Zhenning.

The latter was very happy about Wang Duoyu's arrival and warmly received Wang Duoyu and his party.

Wang Duoyu spent two days at Stony Brook University and did not go anywhere. He just stayed in the school, either learning and exchanging knowledge about physics with Yang Zhenning, or visiting the school's advanced equipment.

What’s interesting is that Yang Zhenning actually jokingly asked Wang Duoyu to help him calculate some math problems that required a lot of computational power.

Wang Duoyu would definitely be happy to do such a small favor.

Yang Zhenning finally witnessed Wang Duoyu's terrifying mathematical talent, which was really like a supercomputer, or even more terrifying.

"If I used a computer to calculate it, it would take at least a week to complete. I didn't expect you to only need half an hour."

Upon hearing this, Wang Duoyu just said a few humble words.

While chatting, Wang Duoyu did not ask the other party why he didn't return to China?
As a pure theoretical physics researcher in the physics community, it would be better for Yang Zhenning to stay in the United States than to return to China.

Because at that time, China still did not have the ability and funds to provide Yang Zhenning with the ability to develop pure theoretical physics research.

For example, many scientific research topics involve a lot of calculations. The United States has very advanced supercomputers, but what about China?
The best computer now should be the distributed computer that is under construction in the teaching building of the Department of Computational Mathematics of Harbin Institute of Technology.

Based on Wang Duoyu's design, the final computing power of this distributed computer will definitely exceed that of a supercomputer with an operating speed of 80 million operations per second.

But even this level of computing power is still not enough for Yang Zhenning.

We can't let Wang Duoyu help Yang Zhenning every day and assist him in verifying his research projects, right?
Wang Duoyu is not a computer, how could he do this?

If it were more than ten years ago, in the era of Yu Min, Qian Xuesen, Cheng Kaijia, and Deng Jiaxian, many mathematicians were indeed just pure "computers", such as Qin Yuanxun, Zhou Yulin and others.

What's more, in addition to supercomputers, Yang Zhenning also needs to rely on other high-end equipment in the United States, otherwise he would not have become an American citizen.

After leaving Stony Brook, Wang Duoyu and his group came to New York and spent a day strolling around famous streets such as Manhattan, but there was no Wall Street Bull yet.

The Manhattan area with its skyscrapers is just that to Wang Duoyu.

But for "country bumpkins" like Wu Congxin and Rong Guangxia, it was jaw-dropping.

So it was very obvious during the whole game that Wang Duoyu spent most of his time with his head down writing on his notebook, while others were shouting.

Although it was very disharmonious, Wang Duoyu was not affected at all, so it seemed quite harmonious from this perspective.

After a short day of fun, Wang Duoyu and his friends took a plane across the North American continent and headed straight to San Francisco the next day.

After arriving in San Francisco, Wang Duoyu and his friends did not adjust to the jet lag. They simply rested for a few hours and then continued their tour.

However, Wang Duoyu was invited to give a lecture at the University of California, Berkeley, which was completely different from his previous visit to Stony Brook University.

He originally planned to stay in California for two days and then return to China, but Qiu Chengtong, Smale and others were unwilling to do so.

In the end, there was no other way and it was delayed for five days.

why?
Because Shing-Tung Yau invited several very famous physics professors in the United States and several aerospace experts to give him one-on-one lessons.

My goodness, with this kind of treatment, is Wang Duoyu willing to leave?
Of course he couldn't bear to leave, so he had to change his plan to return home.

Before leaving, Wang Duoyu was received by the president of the Berkeley University and received a big red envelope: a check for fifty thousand US dollars.

This check was from First Citibank and could be cashed at any time. It was his 'lecture fee'.

Why are lecture fees so expensive?

Isn't it just that he wants to use this kind of "bribe" to keep Wang Duoyu?

It’s a pity that Wang Duoyu’s determination to return to China is not too strong.

When Zhu Hanting saw the check, his pupils dilated instantly, and after he realized what was happening, his eyes turned red.

"what happened to you?"

Rong Guangxia and Mo Ruogao didn't understand why Zhu Hanting lost his composure. After all, Wang Duoyu only got a check for 50,000 US dollars. What was the big deal?

You should know that when Wang Duoyu was at Harbin Institute of Technology, he personally proposed the Diaopai Company, which has now received foreign orders for battery products exceeding 100 million US dollars.

There is no comparison between fifty thousand US dollars and one hundred million US dollars.

Although 100 million US dollars is only the sales amount of export products, it is not even a profit, let alone Wang Duoyu's personal money.

But this was all Wang Duoyu's doing, not to mention the handheld game console project. Maybe he can create even more miracles.

"What's wrong? Do you know how long it takes to make $50,000 in the United States?"

Zhu Hanting asked with red eyes, Rong Guangxia and the others shook their heads, of course they didn't know.

Over the past half month, they have been staying with Zhu Hanting and learned a lot about the United States from him.

However, Zhu Hanting never talked about how to make money.

At this moment, Wang Duoyu had already put away the check with a smile and came to Zhu Hanting and the other three:

"What are you talking about? We should go back."

Rong Guangxia and the others looked at Zhu Hanting, smiled and nodded in agreement, but the latter spoke with a complicated expression about how difficult it was to survive in the United States.

After Zhu Hanting finished speaking, Wang Duoyu commented with a smile:
"It seems like you've finally gotten the message, Old Zhu. That's a good thing. I've told you before that America is for the rich. In the eyes of the poor, America is a country of misfortune, where life will be harder than a dog's."

"As long as you have the ability, you can live a very comfortable life in the United States. But if you are broke, even breathing costs money."

"So you learned a lot from studying in the United States."

Zhu Hanting had no intention of continuing his studies in the United States, but instead gave up halfway and chose to return to Harbin Institute of Technology with Wang Duoyu and others.

Jian Xianglan is still here, and Zhu Chengwu also chose to stay at Princeton University.

I won’t mention the former, but Zhu Chengwu himself was unwilling to stay at Princeton University. It was Wang Duoyu who suggested that he stay.

Zhu Chengwu has a good talent for mathematics, but he is obviously not suitable for research in areas such as applied mathematics. On the contrary, he is very suitable for pure theoretical research.

In that case, let him take this opportunity to stay at Princeton University and slowly climb up.

Wang Duoyu could not help Zhu Chengwu much with pure mathematical theoretical research, and Wang Duoyu himself did not have that much time.

Lu Jiaxi is an example of this. Although he has entered Harbin Institute of Technology and has escaped the tragic trajectory of his original time and space, Wang Duoyu does not have much communication with him.

Princeton University is one of the world's mathematics centers, and Zhu Chengwu will be able to develop better if he stays here.

After he finishes his studies, he will come back to Harbin Institute of Technology and lead the Department of Mathematics of Harbin Institute of Technology forward, which may give Harbin Institute of Technology the opportunity to become a domestic mathematics center in the future.

As one of the world's top mathematicians, Wang Duoyu's presence can actually gradually attract more mathematical talents.

If there were one or two more top mathematicians like Wang Duoyu, the Mathematics major in the Department of Computational Mathematics at Harbin Institute of Technology would definitely be ranked first in the country.

It can even compete with the world's top universities such as Princeton University and Berkeley.

However, Wang Duoyu may not have so much time and energy to lead the development of the mathematics major at Harbin Institute of Technology. On the contrary, Zhu Chengwu is very suitable.

Besides, Xue Xiaoling, Rong Guangxia, Mo Ruogao and others have returned to China. We have to leave some seeds in other places, or "learn from the barbarians to defeat them". We can't continue to develop in isolation in the future, right?
If the mathematics major at Harbin Institute of Technology wants to develop, it needs talents from all walks of life.

"Ok!"

Zhu Hanting nodded in agreement. He now admired Wang Duoyu very much and had decided to cling to the latter's support.

After leaving Berkeley, Wang Duoyu asked Rong Guangxia and others to take the check and go directly to First Citibank to exchange it.

He did not go to exchange it in person, and Wu Congyin would not let him do such a small thing in person.

After receiving 50,000 US dollars, Wang Duoyu set off to return to China.

This $50,000 is quite embarrassing. It seems like a lot, but if it is used to buy some high-end equipment, it is not even a fraction of it.

For example, Wang Duoyu wants to buy a photolithography machine. Haha, that is a device that costs 450,000 US dollars. How can he buy it?
And it is not available for purchase at all, because the lithography machine needs to be ordered. Simply because the stepper lithography machine is so popular, GCA company cannot produce enough, so you can only wait in line to get it.

Otherwise, they buy it from the secondary market, which is the so-called scalper party.

So there is no need to spend this money, just take it home.

After taking off from San Francisco Airport, it was another long flight. By the time Wang Duoyu and his team landed safely at Beijing Nanyuan Airport, it was already July 26th.

By this calculation, Wang Duoyu and his companions were away for twenty-one days in total, which is indeed a very long time.

After arriving in Beijing, Wang Duoyu only met with Zhu Ling once, and then hurried back to Harbin Institute of Technology.

Because at that time, there were already many students waiting for him at Harbin Institute of Technology.

Yang Nianzhen, Ding Haiyang and other Peking University students who went to the United States with us also went to Harbin Institute of Technology after landing because they also wanted to attend the next courses.

July 27, 1980, in a lecture hall at Harbin Institute of Technology.

Since there are so many students this time, more than 200 in total, it is impossible to place the class in an ordinary classroom and can only be held in a lecture hall.

When Wang Duoyu appeared at the door of the classroom, the whole classroom became quiet in an instant.

"Hello everyone, I'm Wang Duoyu, and I'm happy to announce that you're all welcome to the Hell Classroom."

On the podium, Wang Duoyu took out the chalk with a smile and started the class.

He didn't bring any books with him at all; he came empty-handed.

Yang Nianzhen and other students who had already attended his lecture did not think there was anything wrong with it, but students from Fudan University, Xiamen University, Sun Yat-sen University, Shanghai Jiaotong University and other universities all looked curious.

"I taught a course last summer and another in March of this year, both on the Poincare conjecture. I'll also be teaching you about it."

"But I need to tell you that there were 40 to 50 people in a classroom at the time, but only 39 stayed, and only a handful of them were able to fully understand my lectures."

"And ultimately, only four people were able to write excellent papers and publish them in American professional journals."

Wang Duoyu's eyes swept across the entire lecture hall:

"There are a total of 227 students sitting in this classroom today. I don't know how many of them will be able to persevere to the end, and how many of them will be able to fully understand my lectures."

"Your school asked you to come to my school for classes during the summer, and you all took the test and scored over 80 points before being selected."

"You are supposedly the best of the best, but here you might feel like you're sitting in hell."

No matter how arrogant a genius is, it is useless here because they are just ordinary people.

After Wang Duoyu finished talking a lot of nonsense, the lecture began.

He stopped talking nonsense and got straight to the point.

Although some students, such as Yang Nianzhen, have studied Wang Duoyu's four papers on the Poincare conjecture for twenty or thirty pages, some people have only read the first few pages.

Everyone’s progress is different, but Wang Duoyu still starts teaching from the first page.

Two hours in the morning and two hours in the evening every day.

Wang Duoyu didn’t have time to think about whether they could digest it or not.

Harbin Institute of Technology has already received "benefits", and in an equal exchange, Wang Duoyu must pay something.
