In the evening, the official website of the Mathematical Society also issued an announcement, announcing a series of winners.

Some reporters on the scene released the news early.

A lot of media outlets started to report on it.

Among the three major awards of the Domestic Mathematical Society, the Hua Luogeng Mathematics Award is the most heavyweight, but because the winners are all academicians and top professors of mathematics, it has not received much attention, and there is nothing special to discuss.

The winners of the Zhong Jiaqing Mathematics Prize are all doctoral students, and it is difficult to attract attention for the results of doctoral dissertations.

The most noteworthy thing is that Wang Hao won the Chern Prize in Mathematics.

On the day before the start of the meeting, Wang Hao's latest research on 'approximate solution of NS equation' has been on the hot search of public opinion, causing many people to discuss.

Now he has won the Chern Prize in Mathematics, which is also a recognition of his work and research in mathematics.

Many people discussed, "Wang Hao is really amazing, he has created a record for the youngest age of the Chern's Mathematics Award!" ”

"26 years old, Chern, estimated to be less than thirty Fields."

"Wang Hao's achievements are enough for Chen Shiing, if you don't judge Wang Hao, it's strange!"

"I don't accept anyone else's awards, just serve Wang Hao!"

"At the same time, there is also a Zhong Mingchu who won the award, but I have never heard of it."

At the same time, some top mathematicians also accepted interviews with reporters about the awards.

The vast majority of mathematicians are not well-known, and even the top mathematics professors of a university are difficult to be known by many people.

However, some of the top mathematicians are different.

For example, Qiu Chengwen.

Qiu Chengwen can be said to be one of the most famous mathematicians in the domestic mathematics circle, and he is also very influential in the domestic mathematics community.

In an interview, Qiu Chengwen talked about his participation in the Mathematics Society, "I did not attend the last conference or the last conference, because my main focus is on educating and cultivating young talents. ”

"But this time is different, I'm here for Wang Hao's research."

"Of course, it is not the study of the equation, but the mathematical method of his research for the infinite change of columnar formulas."

"This method, I think, has reached the Fields level, and his report has attracted the attention of the international mathematical community, and it has been confirmed that it will be published in Acta Mathematica Sinica, a subsidiary of the Institute of Mathematics of the Academy of Sciences."

"The reason why I say that I have reached the Fields level is because this mathematical method can greatly advance the study of number theory and algebraic geometry, and can bring new ideas and methods to many studies."

"Here, I dare to say, the next Fields will definitely have a Chinese name."

This Chinese name, naturally needless to say, must be Wang Hao.

Qiu Chengwen's affirmation caused another round of heated discussions in public opinion.

There has never been a Fields winner in China, and the Fields Medal has only been awarded to two Chinese until now, one is Qiu Chengwen and the other is Tao Zhexuan.

Qiu Chengwen was an Ameriken national when he won the award.

Tao Zhexuan is an Australian national.

They can only be said to be Chinese, not Chinese, and they have received foreign education since childhood.

There is great hope that a real Fields winner will emerge in the country.

Now that it has been affirmed by Qiu Chengwen, and when it comes to the next Fields, there may be Wang Hao's name, and many people are looking forward to it even more.

Public opinion that day was full of Wang Hao's reports.

Wang Hao is very low-key, he just rests in the hotel, and the next morning he goes to the meeting normally, because he doesn't need to make a report, he goes to various halls to look and listen to some content related to the research field and his own interests.

He listened to the report for a whole day and didn't make any comments, just listened carefully.

A lot of research can also make him feel that he will have some ideas in his own research.

This is reflected in the increase in inspiration value.

Both tasks have increased a little bit of inspiration, and although the increase in value is not much, the knowledge and ideas that can be brought are still a lot of gains.

By the second day, however, the number of participants was significantly smaller.

The team of the Institute of Mathematics of the Academy of Sciences, including many top mathematicians and scholars from universities, has left ahead of schedule.

The purpose of their coming was to listen to Wang Hao's report, and since the report had ended, there was naturally no need to stay.

Wang Hao and Luan Haiping's plane was also on the morning of the third day of the meeting, and they were not ready to attend the rest of the meeting.

As we entered the third day, all that was left was a few small presentations and some working session reports.

On the fourth day, it has nothing to do with most other scholars, and the Mathematical Society will hold enlarged meetings, council meetings, secretarial meetings, organizational work meetings, and so on.

To put it simply, it is to adjust personnel and work internally.

Wang Hao and Luan Haiping took a plane back to Xihai City together.

After getting off the plane, Wang Hao went back to put his luggage and belongings, and then went to the office of the comprehensive building, busy preparing the lesson plan for the evening class.

Meanwhile.

Luan Haiping also went to the laboratory building of the Faculty of Science.

When passing by the teacher's office, Luan Haiping went in and took a turn, and suddenly several professors looked over.

Zhou Qingyuan immediately asked, "How about this time?" I watched the news, Wang Hao won the Chern Mathematics Award! ”

"The school hasn't made an announcement yet, and Director Yang of the Publicity Office just said that when you come back, it seems that you want to talk about the announcement."

Luan Haiping nodded, indicating that he would go and have a look in a while.

Then several professors talked about Wang Hao again, "There are a lot of people in this mathematical meeting, right?" Dean Luan, didn't you introduce a few top scholars to Wang Hao? He's still young, and it doesn't hurt to get to know some more people in the math community. ”

"Now that he has won the Chern's Mathematics Award, he is also considered to be the top in the mathematics circle, much better than those of us."

"It will be helpful to know more powerful people in the math circle in the future."

"Dean Luan, I still want you to go out and take care of it more on such an occasion, Wang Hao is too young after all."

Several mathematics professors are very concerned about Wang Hao.

They wanted to come to Luan Haiping and Wang Hao to attend a mathematics conference together, and it must be Luan Haiping who took care of Wang Hao, because Luan Haiping would participate in every meeting, which can be said to be experienced and knew many people.

Luan Haiping grinned, but he couldn't say a word, he recalled the process of attending the meeting with Wang Hao, and felt that he was completely a foil.

Take care of Wang Hao?

What an international joke!

Every time he walks with Wang Hao, he is always the one who is ignored.

The others came over to shake hands with Wang Hao, and completely left him aside, and after experiencing it several times, he simply stopped with Wang Hao.

So that someone could finally recognize him.

Is this what he took Wang Hao to a meeting? This is Wang Hao taking him to the meeting!

After Wang Hao greeted others, he also helped introduce Luan Haiping, and that scene was as embarrassing as it was.

"Alas~~~"

In the end, Luan Haiping let out a long sigh and said, "If there is a meeting like this in the future, you should go, and I will give you the quota." ”

"This kind of exchange opportunity is more suitable for you to go."

"I'm old, I can't do it anymore......"

……

Wang Hao was busy sorting out the lesson plans in the office of the comprehensive building.

In the evening, it was "Fundamentals of Theoretical Physics", and the reason why he rushed back was so that he did not miss the class.

The study of the NS equation is important, as is the study of annihilation.

Moreover, he feels that in the study of physics, his progress is very fast, and every time he takes "Fundamentals of Theoretical Physics", he feels that he has gained a lot in the basic content.

The same goes for the course of the day.

In the course of one class, the task gained two points of inspiration, and I felt that I had new gains and ideas for the microscopic mathematical system.

The next morning, Wang Hao went to the teaching and research department to sort out his new gains in the NS equation.

"Knock knock."

There was a knock on the office door.

"Please come in!" Wang Hao shouted and raised his head, and saw Luan Haiping walking in with a middle-aged man.

"Didn't bother?" Luan Haiping said politely, walked in and sat down the middle-aged man, and then introduced, "This is Professor Cui Xunnian." ”

He then made a brief introduction.

Cui Xunnian, who is called 'professor', is actually a researcher in air-ground dynamics, and has been engaged in the research of low-altitude flight of aircraft for a long time at an equipment base.

Wang Hao was immediately in awe when he heard this.

There are many experts in China who are engaged in the study of military equipment.

People engaged in similar research will hardly appear in the public eye, and even if there are many major achievements, they will not be reported, so it can be said that they are doing scientific research in obscurity.

Choi Hoon-nian is one of them. The study of the dynamics of aircraft flying at low altitudes is obviously directly related to fighter jets.

Wang Hao hurriedly stood up and shook hands with Cui Xunnian.

Cui Xunnian looked very serious, and saw Wang Hao with a smile on his face, but he didn't have the feeling of a philistine like an ordinary person, and he had a bit of a military-human temperament all over his body.

After he shook hands with Wang Hao, he directly explained his intentions, "We have recently encountered problems in research, and we have found many other experts, but we can't solve them." ”

Cui Xunnian didn't say in detail, but handed over a document, and after opening it, he listed a complex system of equations, "It's this system of equations, we hope to find several sets of closest solutions, but the results obtained by numerical substitution, during the experiment, found that it is not ideal." ”

Wang Hao listened to it and almost understood.

This involves the design of the aircraft.

Aerodynamics is a branch of fluid mechanics, and aircraft design must involve the content of the NS equation, which will adopt the design to minimize wind resistance and increase the efficiency of engine air intake.

However, how to solve this problem to the maximum extent involves very complex calculations.

When you encounter some difficult designs and have higher performance requirements, you need to get more accurate values.

This is a difficult question.

The solution of partial differential equations is originally a direction of study, and most of the NS-related equations cannot be solved by existing means.

If you just find an approximate solution, the degree of approximation cannot be judged.

Cui Xunnian continued, "I read the latest report, Professor Wang, your research on the approximate solution of the NS equation has reached the highest level in the world. I really hope you can help me with this. ”

Wang Hao glanced at the equation system and said, "I'm still doing related research recently, and I'll try it." ”

"Thank you, it's important for our research."

Cui Xunnian said a few more words, and left with Luan Haiping.

After a while, Luan Haiping seemed to have sent Cui Xunnian away, and came back to explain, "Professor Cui came up suddenly, and I don't know the situation. Is that equation system very difficult? If they can't solve it, it's nothing, and it is said that they have found a lot of scientists and experts in fluid mechanics but have not solved it. ”

He shook his head as he spoke.

Wang Hao looked at the content on the paper and said, "I just gave it a try, and I don't dare to guarantee it 100%. I've been working on this lately, so it's a good idea to take a look at the app when I have time. ”

"It's best if you don't delay your research." Luan Haiping was a little worried that Cui Xunnian's coming to the door would affect Wang Hao's own research.

Wang Hao shook his head and said, "It's okay." ”

After Luan Haiping left, Wang Hao took a serious look at the content on the paper, which was a system of equations in the field related to the NS equation.

He looked carefully at the contents of the equation and was suddenly stunned.

He had been thinking about a question before, because many NS equations may not have exact solutions, how to study approximate solutions that are infinitely closer to exact solutions?

Now, the answer to this question is out.

Equations.

A single NS equation is indeed a partial differential equation problem, but a more complex system of equations can be understood as a system of partial differential equations, and the difficulty naturally rises to a higher level.

It is even more likely that a single partial differential equation will not be able to find an exact solution, and it is even more likely that there is no exact solution for the system of partial differential equations.

But there's one thing --

An infinite number of 'approximate solutions' can be obtained, in which you can find them, which is closer to the 'solution' that smooths the image of the original equation.

This involves algebraic geometry.

The image composed of the imaginary number solution will be very complex, because the exact solution cannot be found, and the image of the solution is not clear, so it can only be vaguely described in the form of approximate value.

Then a certain 'approximate ungrouping' can make the graph line appear smoother, which is closer to the exact solution.

"That's too complicated!"

Wang Hao had a little headache when he thought about it, but he knew that his thinking was correct, so he began to study it slowly.

……

The next day was another day with classes.

"Modern Partial Differential Equations" is a course that Wang Hao attaches great importance to, because the course may bring inspiration to the study of NS equations.

After completing the explanation of a class, several students came around to ask questions, and Wang Hao answered them one by one, which took about half an hour.

At this time, it is almost over, even if the student has any more questions, he will not continue to answer, after all, he is not a 'answering device' for the student, and it is okay to answer questions for half an hour more.

But two students stayed.

Wang Hao looked up and was a little surprised, it was two graduate students in informatics under him.

Zhang Xinyi and Li Xin.

He asked curiously, "How did you come to this class?" ”

Modern Partial Differential Equations is a very complex mathematics course, and functional analysis, even nonlinear functional analysis, is only the basis of the course, and graduate students in informatics generally do not have access to it.

Li Xin shrugged his head and said, "Teacher Wang, we're here to ask questions. The information you gave us was completely incomprehensible to the two of us. ”

"Like ......"

Zhang Xinyi immediately took out the information in his hand and put it on the podium, showed it to Wang Hao, and said, "This part of the content is just the second page, we have thought about it for a long time, but we haven't understood it. ”

"This calculation transformation? Why? ”

"From functions and sets, suddenly jump to this step, how do you deduce it?"

Wang Hao glanced at it, and knew what Zhang Xinyi was talking about, he explained, "This is very simple, it involves ......" He suddenly reacted, stopped talking and said, "I understand." ”

"Huh?"

Zhang Xinyi and Li Xin looked up together.

Wang Hao smiled, "Do you want to eat a fat man in one bite, and you can eat this information directly?" ”

"How is this possible?"

He walked out of the podium, took the stack of materials, and said, "The effective and irrelevant carry screening method is very difficult, and you must first have a certain foundation to understand all the contents. ”

"So be it."

Wang Hao thought for a while and said, "I recommend that you learn functional analysis on your own, as well as discrete mathematics, and the content of probability theory should also be grasped." ”

"You just study these three courses while you study the content of the materials."

"Take your time, don't rush, in another three months, I'll check on your progress."

“……”

“……”

Zhang Xinyi and Li Xin were both stunned, they are graduate students in informatics, and they have to study three difficult mathematics courses?

Wang Hao felt that the students still needed more comfort, and said with a smile, "This is all the foundation, I have high expectations for you, come on!" ”

Zhang Xinyi and Li Xin glanced at each other, and could only leave with bitterness, they initially felt that it was definitely okay to just study an algorithm data and spend more time.

They are much better than the graduate students in the Department of Mathematics, and they don't have to look for the direction by themselves at all, Wang Hao has already explained the direction.

It turned out that I was thinking too simply!

Valid vs. irrelevant carry filtering?

It's a big hole, and if you think about it, they definitely won't have any free time for the next three months.

Looking at the backs of the two leaving, Wang Hao had some expectations.

Of course, he didn't expect much help from the graduate students, but he still looked forward to the two graduate students in informatics.

As long as their foundation keeps up, they can still do some leftover work in programming and other fields.

Then there are some programming problems that can be handed over to the students, instead of wasting a lot of time on their own.

……

In the next nearly half a month, Wang Hao's life has been very dull, that is, he accumulates inspiration points in class, and the rest of the time he does research patiently.

He has made a lot of progress in solving the NS equation approximation and knows how to do the transformation to make the approximation more accurate.

The method is to compare the replacement equation with the original equation on the basis of the original results, and do a more detailed analysis, so that the substitution equation can continue to be improved.

In this way, step by step, the approximate solution can be closer to the exact solution.

For partial differential equations, it is relatively more complex, but as long as it is slowly transformed, it is still possible to obtain a more accurate approximate solution.

But occasionally I still encounter some problems, and some can't figure it out, especially when studying the system of equations given by Cui Xunnian, it is difficult to change each step.

Wang Hao has already come up with some results, but he feels that he can continue to refine them and make the values obtained by solving them more 'ideal'.

At the same time.

Choi Hoon-nyun is doing the same research.

The problem of analyzing this system of equations has been bothering him for a long time, and some of the solutions obtained have been found to be unsatisfactory after experiments.

He wanted to be able to get a more precise disassembly.

After looking for Wang Hao, Cui Xunnian still had high expectations, but three weeks have passed, and the other party doesn't seem to hear back, not even a single inquiry.

Cui Xunnian felt that it seemed a little bad to go over and ask directly, so it was indispensable to inquire about it.

He asked Peng Hui.

Peng Hui knew Cui Xunnian when he joined the army, and they have been in contact with each other.

Cui Xunnian knew that Wang Hao had participated in Peng Hui's project, so he called directly, and the old friend called to say hello, and then turned to the topic, "You know Wang Hao, right?" ”

"I know Wang Hao very well." Peng Hui immediately said, "You know, Wang Hao, he's too genius!" ”

Cui Xunnian said, "I asked him a math question, but it has been twenty days, and there is no reply, so I want to ask you about it and see what the situation is?" ”

"Tell me?" Peng Hui asked with interest.

"It's a complex system of equations that people in our institute can't solve, and we can't solve it even if we find others." Cui Xunnian said, "So I looked for Wang Hao, but there was no news for a long time." ”

Peng Hui thought for a moment and asked, "You guys have a difficult system of equations, right?" ”

"Of course."

"It's so difficult, it should be worth solving this problem, right?"

"Of course, this is directly related to the design issue, and it is also interesting for future research."

"Did you give the money? It is the project fee and labor fee. ”

"No?"

Peng Hui nodded and asked, "Then I understand." ”

"Huh?" Cui Xunnian was suddenly curious, "Why?" ”

"Isn't that obvious! Are you too embarrassed to ask? Peng Hui asked rhetorically in a loud voice, "Your research is so difficult and so valuable, and you don't take a penny, so you let people help with your research, and I will assign a job to a graduate student, and I will pay for labor services." You can find an expert to help you, and you won't pull out a dime! ”

"Mathematicians also have to live, do you think it makes sense for people to spend so much energy to help you do research without giving you a penny?"

"Even if you're a military-affairs research institute, you can't do that!"

PS: I recommend my friend 'Pig Head Seven's fire book "My Spy War Years", the first book in the military category, more than 2 million words are enough, interested relatives can take a look.
