Chapter 137: The right time, right place, and right people; the son-in-law is true love, and the daughter is an accident
"Zhu Ling, your man seems to be back, go back and check on him."

At the gate of No. 6 Xila Hutong, Zhu Ling had just got off work and was about to go in by pushing her bicycle. A word from the neighbor lady immediately made her smile with surprise, and then she walked quickly towards home.

Seeing how enthusiastic she was, the neighborhood aunties all laughed out loud, and their eyes became more ambiguous.

why?
Because the aunts are all experienced people and know what it means to be more happy after a short separation.

Wang Duoyu and Zhu Ling have not yet obtained their marriage certificate, but they have already "jointly invested" in buying a house. The small courtyard is their "wedding house", and this matter has also been supported by Zhu Ling's parents.

So in the eyes of the neighborhood aunties, they are just a couple.

Although the aunties had only seen Wang Duoyu once and were not very familiar with him, he was tall and handsome. Even in Beijing, he was a rare tall and handsome guy.

What's more, Wang Duoyu's scholarly temperament is not something that ordinary people can imitate.

"Duoyu, are you back?"

Before entering the small courtyard, Zhu Ling shouted loudly, but Wang Duoyu didn't say anything.

Just when she parked her bike and pushed the door open to walk into the room, but saw no one, she was hugged unexpectedly at this moment, which scared her.

She struggled violently, but Wang Duoyu refused to speak, which made her even more frightened.

The next moment, she saw Wang Duoyu's profile and immediately punched him several times in anger:
"You scared me to death. Why didn't you say anything? You just bullied me."

Fortunately, her voice was not very loud, and she was in the house, so it did not spread outside the courtyard. However, all the little kids in the yard ran to the small courtyard.

"Shame on you, shame on you, you're still hugging each other even though you're so old!"

When the voices of the little kids were heard, Zhu Ling immediately broke free from Wang Duoyu's arms, walked out the door angrily, and drove the kids away.

After everyone had run away, Zhu Ling turned back fiercely and shouted at him:

"It's all your fault. I won't be able to hold my head up in this yard anymore."

"Okay, it's not that serious. It's just between the two of us, and it has nothing to do with other people. If you're worried, how about we go get the marriage certificate tomorrow?"

Upon hearing this, Zhu Ling blushed immediately, buried her head in her chest and remained silent. Seeing this, Wang Duoyu hurried forward and hugged her.

He is a human being with emotions and desires. Although he often restrains his emotions, he has seen Zhu Ling, so there is no need to restrain himself.

After a while, the two of them were almost intimate, and Zhu Ling shyly pushed him away and started chatting.

Upon learning that he was going to attend an exchange meeting at the Jingxi Hotel the next day, Zhu Ling immediately postponed the time for getting the marriage certificate.

Besides, if we really want to get a marriage certificate, we must discuss it with her parents.

As for Wang Duoyu, after getting the marriage certificate, he will find time to go back and meet his elder brother.

"These two days are both working days. Otherwise, you can come to the Jingxi Hotel. I told you, the Jingxi Hotel is very beautiful inside."

Hearing Wang Duoyu's words, Zhu Ling rolled her eyes at him unhappily:
"Who wants to read this? I'm just a medical student who hasn't even graduated yet. I'm not qualified to go to the Jingxi Hotel. Besides, why would I go there? I don't understand what you're talking about."

Makes sense!
Wang Duoyu was just chatting with her and had no intention of taking her there.

Anyway, the 18th is a Wednesday, and Zhu Ling happens to have a day off. She can come to Peking University to attend his academic lecture. It is not a problem to reserve a seat for her.

A short separation is better than a new marriage. That night, Wang Duoyu wanted to hug her and sleep together, but she stopped him.

He can only kiss her before going to bed, but he is not allowed to sleep together.

How is this possible?
She is now one of their own, and Wang Duoyu has no intention of letting this little lamb go.

More than two hours later.

On the bed, the two of them hugged each other after washing up.

Zhu Ling suddenly became angry and bit his shoulder: "Humph, are you satisfied now?"

"It doesn't matter whether I am satisfied or not, your satisfaction is the most important thing."

Wang Duoyu responded with a smile, and he didn't take the small tooth mark on his shoulder seriously at all.

But his words immediately made Zhu Ling even angrier. This matter can only be understood but not expressed in words.

Of course she was angry when Wang Duoyu said that.

So, I took another bite at the same spot.

"If you bite me again, you'll have to give me a rabies shot later."

"You're still talking!" Zhu Ling was immediately amused. "You just said you'd give me an injection. Why haven't you given it yet?"

Hearing her bring up this matter, Wang Duoyu was immediately happy.

After he finished explaining, Zhu Ling's eyes widened instantly, her pupils showing shock, and the next moment she elbowed him in frustration.

so bad!
However, women don’t love bad men.

In Zhu Ling's view, she had found a treasure!

"Come back with me to my parents' house for dinner tomorrow night. We can't put off getting our marriage certificate any longer."

"Yeah, no problem!"

Wang Duoyu agreed readily.

They take advantage of people completely, and typically buy tickets after getting on the bus. For them, it's a huge profit, so it's no problem to just buy a ticket.

The next morning, a car stopped at the entrance of the alley on time. Many passing neighbors saw this scene and couldn't help but take a few more glances.

Xila Hutong is not the residence of high-ranking officials and nobles. On the contrary, it is right next to Wangfujing Street. In the past, it was the residential area of ​​wealthy businessmen.

Therefore, almost all the people living nearby are ordinary people, and it is rare to see cars here.

When Wang Duoyu got into the car with his handbag, many of his neighbors who knew him were surprised.

Jingxi Hotel has become more lively with the arrival of Wang Duoyu.

A lot of people have gathered in the small conference room, including Chen Jingrun, Tao Fangqi, Yang Le and others.

Smale stood next to Chen Xingshen. After Chen introduced Wang Duoyu's identity, he immediately stepped forward and offered a handshake:
"Wang, hello, I'm finally meeting you. Tell me, how did you come up with this idea? From a four-dimensional perspective, the Earth is actually a three-dimensional membrane, and the singularity of a black hole is precisely the point formed by the contraction of this three-dimensional membrane. My God, what a brilliant idea!"

At this moment, Smale immediately entered the state and didn't want to exchange too many pleasantries.

Wang Duoyu immediately smiled and started communicating with the other party in English with a slight Chinese accent.

Andre Weil, Charles Fefman, John Milnor, Robert Langlands, Shing-Tung Yau, Lars Valerian and others on the side listened quietly to Wang Duoyu's words.

Tao Fangqi, Chen Jingrun and others remained silent and listened attentively.

Wang Duoyu had only said a few words when he saw Smel had already started writing on the small blackboard next to him, and today's communication officially began.

Although we are talking about the Poincare conjecture, it is no longer entirely about the proof paper in four-dimensional space, but more about the proof in three-dimensional space.

why?
First, it is rare that so many mathematicians have gathered here. Many of them are world-class mathematicians. Some of them have received awards, while others have not, but this is not important.

For example, John Milnor, the winner of the Fields Medal in 1962, was born in 1931 and is only 48 years old this year. He is not young, but he cannot be said to be very old either.

For example, Chen Jingrun published his '1+2' paper in Science Bulletin in . The entire paper was more than pages long.

However, because no detailed proof was published, it was not recognized by the international mathematical community.

If he had published the detailed proof at that time, he would have had a good chance of winning the Fields Medal in 1966, or even in 1970. Unfortunately, the situation was very complicated at the time, so it's hard to say.

However, no matter what, whether it is John Milnor or Chen Jingrun, these people are all top mathematicians in the global mathematics community today.

Second, Smale, Shing-Tung Yau, Robert Langlands and others all wanted to see, or successfully prove, the entire Poincare conjecture and solve this problem that has plagued the global mathematical community for more than half a century.

Smale and others are well aware that solving this problem will play a very important role in promoting the development of global mathematics.

Every N-dimensional sphere wraps around an N+1-dimensional world. In other words, every N-dimensional world is supported by an N+1-dimensional world.

So this is contrary to what we usually think. The low-dimensional world exists precisely in dependence on the high-dimensional world, because the low-dimensional world is just the boundary of objects in the high-dimensional world.

As Wang Duoyu mentioned in that paper, with the help of the entropy flow of the Poincare conjecture and the use of hollow spheres without tearing or jumping, the inner surface can be flipped into the outer surface, which can prove the origin of the arrow of time and can also link thermodynamics with quantum theory, relativity, superstring theory and loop quantum gravity.

Therefore, once the Poincare conjecture is proved, it will help humans better study three-dimensional space, and the results it brings will deepen people's understanding of the properties of manifolds.

Third, in 1972, Shing-Tung Yau collaborated with Wei-Kuang Lee to develop a set of nonlinear differential equation methods to study the theory of geometric structures, and in 1976 he used this method and the concept of curvature in Calabi geometry to prove the Calabi conjecture.

Searle once said that the solution to a truly good mathematical conjecture should be followed by a series of inferences and continuous impacts.

The Calabi conjecture is such a conjecture.

This year, Shing-Tung Yau visited Cornell University for academic exchange and met Hamilton, who was studying Ricci flow.

Although Hamilton had not yet achieved any important results in his study of Ricci flow, Yau was convinced that some discoveries would be made.

Since Shing-Tung Yau proved the Calabi conjecture, he has been in a state of great inspiration. In the past period of time, he has been collaborating with others to study the proof of the positive mass conjecture, the proof of the mirror symmetry conjecture, and so on.

He was even very interested in the study of the properties of manifolds, and the Poincare conjecture was closely related to the properties of manifolds.

The current situation is that the time, place and people are all right.

Smale proved the Poincaré conjecture for five-dimensional and higher spaces, and Shing-Tung Yau proved the Calabi conjecture, further promoting the proof of the Poincaré conjecture.

Wang Duoyu proved the Poincare conjecture in four-dimensional space, and now all three of them are present. At the same time, Qiu Chengtong is only 30 years old this year, and Wang Duoyu is only 23 years old.

Both of them were young and strong, their brains were at their peak, so Smale didn't go through any more pleasantries and went straight to the point.

Chern and others were listening attentively and did not notice the passage of time.

Even though Andrei Weil was old, he was holding his urine and listening attentively, with no intention of leaving.

In front of the small blackboard, Wang Duoyu was still writing and calculating something.

Next to him, Shing-Tung Yau was also calculating, and Chen Jingrun was holding his own paper and pen, writing and drawing at his seat.

As time passed, lunch time came quietly. When Liu Deben saw this scene, he couldn't bear to interrupt and could only watch quietly.

If your train of thought is interrupted, you may become a sinner in history.

I don’t know how long it took, but Wang Duoyu stopped writing because his stomach was protesting and he was indeed a little hungry.

"Let's eat first."

When he said this, Qiu Chengtong, Smale, Chen Jingrun and others were interrupted in their thoughts, and then they were filled with extreme hunger and the urge to urinate.

If you don't drink water for a long time, the human body can actually hold urine for more than five hours.

However, when I ran to the toilet at this time, the water from the Yellow River that was rushing down three thousand feet was very turbid.

Jingxi Hotel has a kitchen, so it is very easy to eat. You don’t need to leave the meeting room. You can just ask the kitchen to bring the food over.

Wang Duoyu and his colleagues had a quick lunch and then got back to work.

However, to be honest, this kind of communication is very effective. Unfortunately, Wang Duoyu feels that this is not the kind of communication he wants.

Smel is old, and his thinking can't keep up with Wang Duoyu's brain speed, so his efficiency is very low.

Qiu Chengtong is indeed very cool, but where he is inferior to Wang Duoyu is in vision.

For some reason, Wang Duoyu always felt that Shing-Tung Yau was a little petty. He liked to keep some of his innovative ideas secret and would not speak them out openly.

Or maybe Qiu Chengtong himself didn't figure out whether he could express such an idea directly.

The actual situation is that Shing-Tung Yau simply doesn't know how to explain it. It's not that he can't say it, but that he doesn't want to say it.

He noticed it himself and even felt a little annoyed, but he had no choice but to smile bitterly and try to remain silent.

"I'm looking for Wang Duoyu!"

Dusk had fallen outside when a phone call came in to the Jingxi Hotel.

After receiving the call, the hotel staff was a little confused, but still helped find the person.

When Liu Deben learned that someone from Beijing Institute of Technology was looking for Wang Duoyu, he was a little curious, but Zhu Ling did not explain to him in detail. She only said that she had something important to talk to Wang Duoyu about, and Wang Duoyu had already agreed to her.

After hearing this, Liu Deben was confused and didn't know whether he should tell Wang Duoyu about this.

It was simply because Wang Duoyu was arguing fiercely with Qiu Chengtong and Smale in the small conference room. Smale couldn't keep up with their train of thought and was eliminated first, but after careful consideration, he was always able to interrupt halfway through.

This shows that although Smale is old, his brain is actually still very useful.

Not to mention Shing-Tung Yau, his brain speed should be about the same as Wang Duoyu's, so he can keep up with the latter's thinking.

However, Wang Duoyu wants to use Ricci flow to complete a series of topological operations, construct geometric structures, and transform irregular manifolds into regular manifolds, thereby solving the three-dimensional Poincare conjecture. This still requires a very, very large amount of work.

The entire proof process is very long, and even requires the creation of many mathematical tools in the middle before it can be completed.

Because when using Ricci flow for spatial transformation, it goes smoothly at the beginning, but later, there will always be points where the direction cannot be controlled.

"How do we understand the movements of these singularities? I believe this is the key to proving the three-dimensional Poincaré conjecture, and my idea is to use nonlinear differential equations."

Liu Deben looked at Wang Duoyu, who was standing in front of Qiu Chengtong and others as if he was giving a lecture. He originally wanted to interrupt the latter, but fell silent.

At this critical moment, Liu Deben didn't dare to say anything.

So, Wang Duoyu was not disturbed until it got darker outside.

Beijing Institute of Technology, a tube-shaped building where teachers live, the Zhu family on the second floor.

Fang Zhen had already prepared the meal and Zhu Qizhen had already returned home from get off work, but after Zhu Ling finished her call, she waited for more than ten minutes and the phone didn't ring again.

"Lingling, could it be that he has other ideas? Or did you two have a fight last night?"

Seeing that the phone didn't ring for a long time, Fang Zhen immediately speculated wildly. Upon hearing this, Zhu Ling rolled her eyes and said unhappily:
"Mom, what are you talking about? Why did I quarrel with him? He just came back to Beijing yesterday afternoon, and I didn't do anything to him. When I went to work this morning, we were all fine."

"Oh, he must be busy. Don't make wild guesses. He's going to meet those foreigners today. I guess he's going to have some kind of exchange meeting."

"Let's not wait for him. I think he has better food at the hotel and would definitely look down on the simple food we have at home."

After saying that, she came to the dinner table angrily, picked up the chopsticks and was about to eat, but was slapped by her mother.

"Will you die if you wait any longer? Are you that hungry?"

That was the son-in-law she had her eyes on, and Fang Zhen was very satisfied with him, so of course she leaned over to him.

The son-in-law is true love, the daughter is just an accident.

Back at the Jingxi Hotel, it was already very late when Wang Duoyu remembered this incident.

Ruined!
