"Professor Zhuang is here." Shi Zhengan spoke softly.

Opening the car door, Zhuang Weiran got out of the car, tidied up his clothes, took his work permit, and walked directly to the physics laboratory building.

The sentry outside already knew Zhuang Weiran and Shi Zhengan, and they didn't stop them, not to mention that they had work permits.After entering the laboratory building, the first floor is the academic lecture hall, and it will be 10:30 immediately, and most people have already arrived at the academic lecture hall.In the academic lecture hall at this time, voices kept shouting one after another.

"What's going on with this Professor Zhuang? Let us all wait here for him?"

"That's right, you suddenly said that you want to come to the academic lecture hall? Is something serious going on? Could it be Academician Zhuang who wants to run away?"

"No way? He is also an academician after all."

"He is really good at theoretical mathematics and theoretical physics, but he has never done anything practical. I think there is a high possibility that he wants to run away?"

"It doesn't look like I'm going to run away. Maybe there is something important to announce?"

"real or fake?"

"Do you know? I heard, I just heard, he seems to be doing ns equations recently."

"I can't."

"Could it be that he solved the ns equation?"

"Are you kidding, he solved the ns equation?"

"I just started doing it, how could I solve the ns equation so quickly."

In the entire academic lecture hall, all relevant researchers gathered together and discussed loudly, and several academic leaders did not speak.They are also wondering now what exactly Zhuang Weiran wants to do, and they feel that Zhuang Weiran seems to want to do something, which makes people a little unpredictable.

"I said old Ji, what's going on with Zhuang Weiran?" Professor Qian felt that Professor Ji and Zhuang Weiran were the most familiar, and suddenly asked them to come to the academic lecture hall. No one else knew that Professor Ji brought Zhuang Weiran to the Chinese University of Science and Technology. The people in the class should know.

Professor Ji shook his head slightly and said, "You don't know, how do I know? I know as much as you do."

"Impossible, even if Xiao Zhuang doesn't tell you, as his professor, shouldn't you know him well?"

"How many years ago was that?" Professor Ji was displeased, "Besides, his wings are stiff now and he can fly, so I can't control him anymore. I don't know what he wants to do."

"Anyway, I think it's quite strange. Suddenly so many of us come to the academic lecture hall. Maybe there is something important to announce?"

"Isn't this nonsense?" Professor Qian said amusedly, "All of us who participated in the research went to the academic lecture hall. If he doesn't have something important to announce, I really can't stop talking to him."

"Hmm..." Professor Ji frowned, the lines on his already shriveled face became deeper, "Do you think it's about the ns equation?"

"It's not impossible." Professor Qian said thoughtfully, "To be honest, I believe that Xiaozhuang can solve the ns equation."

"Will time be too fast? I remember that his subject was Hodge's conjecture a few years ago. It didn't take long to finish it. Solving the ns equation now is a bit... too much, right? In the past few months, he has not Didn’t you do a project when you’re in love? The project submitted by Dragon City seems to be a part of the Langlands program combined with topology. He plans to continue to study it. I heard...he only started to study ns equations after he came to Luyang. This It's only been more than a month, don't make trouble, how could you solve the ns equation so quickly?"

"If he solves the ns equation so quickly, then let's stop researching and just finish the project for him. With his speed, the plane can be built within a year."

As Zhuang Weiran's tutor, Professor Ji had academic differences with Zhuang Weiran, but he was still a little upset when he heard what Professor Qian said.

"I said Lao Qian, but that's not what I said. Xiao Zhuang has always been very wicked. What if he really did it?"

Professor Qian thought about it for a second, and it was true that Zhuang Weiran was very wicked.It is also really possible to make the ns equation in such a short time.

"Hmm..." Professor Qian said with a wry smile, "If he really made it, I would know why he said that day that he could make a new type of fighter in two or three years."

"However, if he really solves it... we may not be able to continue our project." Professor Qian shook his head, "He once again proved to everyone that he is the most correct. I also want to say that this matter can Give him a blow in the head, come on, if he solves the ns equation, it's not a blow to him, it's a blow to me."

"I said, Old Ji, where did you find this kid? Why is it so evil? It has been so many years, so many people have not solved the ns equation, if he really solved the ns equation... ... We will have a lot of advantages in the manufacture of aircraft and even the manufacture of engines in the future. No one knows the ns equation and its application better than him."

Professor Ji chuckled and said, "This kid has always been evil. When I was studying mathematics with me, I thought he was very evil. After following Tao Hanhai, within a year, Yang-Mills' existence was revealed. And the quality gap was made, and I felt at the time that this kid must be doing the right thing.”

"Unsurprisingly, IU admitted that this kid solved the Yang-Mills existence and quality gap, and then the weak Goldbach's conjecture and Hilbert's question." Professor Ji said with a smile, "I have lived up to my will. He brought him from Dragon City to the junior class of Huake University."

"When I saw this kid for the first time, I thought that this kid must be a talent for studying mathematics. Now you all know that this kid is not only a talent for studying mathematics, he is simply a genius for studying mathematics. In mathematics, physics I don’t need to say more about his physical talent. The title of Mathematics Emperor can be said to complement him.”

"Tsk tsk, look at your appearance, people who don't know think you are the emperor of mathematics."

"Hehe, the Emperor of Mathematics is my student after all, how about you?"

"What's wrong with your student? Don't you know how many times you have taught me? Don't you rely on others to comprehend it on your own." Professor Qian said sourly, "If I went to give lectures at Dragon City University, maybe he is still our National Defense University now. What about the professor?"

"You're sour." Professor Ji smiled and didn't continue talking.

When Zhuang Weiran came to the academic lecture hall, the original academic lecture hall, which was full of voices, suddenly became quiet, and the needles could be heard.

He walked directly to the stage and said seriously, "I won't talk nonsense, I will say one thing now."

"About the existence and smoothness of Navier-Stokes." He paused, his eyes glowed with endless brilliance, and a smile appeared at the corner of his mouth, "I have already solved it."

"..."

Really untied?Did they hear correctly?Zhuang Weiran really solved the ns equation?

Taking a deep breath, many people looked straight at Zhuang Weiran with disbelief, as if they thought Zhuang Weiran was joking with them.

"I won't talk nonsense." Turning around and holding a chalk and starting to write something on the blackboard, Zhuang Weiran said while writing, "The process is more complicated and takes more time. If you don't understand the part, please wait until I finish the calculation. Ask me later."

【…

Assume that the partial derivatives of each variable of u(x, y, z, t) exist

……

utt(x,y,z,0)=0

Calculate the partial derivative of t at both ends of the utt=tΔutt formula:

uttt=ΔutΔut1

At u(x, y, z, 0)=x2y2z, two partial derivatives are calculated for x, y, and z at both ends

……

utxx(x,y,z,0)=utyy(x,y,z,0)=utzz(x,y,z,0)=0Δut(x,y,z,0)=utxx(x,y, z, 0) utyy(x, y, z, 0) utzz(x, y, z, 0) = 0

So t=6 in formula (0) has:

utttt(x,y,z,0)=0

uttttt(x,y,z,0)=u(x,y,z,0)=...=0

……1】

Zhuang Weiran's speed is not particularly fast, but the calculation formula is somewhat complicated and dazzling.

Both Professor Ji and Professor Qian frowned and looked at the formulas on the blackboard. More and more nonlinear partial differential equation formulas made them feel puzzled. Of course, doubts belonged to doubts, but they could still understand them.

It's just that the brows are getting tighter and tighter, and I always feel that something is not right.

No, it's not that something is wrong, I just think it's possible... Their thinking is different from Zhuang Weiran's.

【…

The given expansion method obtains the exact solutions of some nonlinear partial differential equations. Next, we will use this method in order to obtain more new results for the cubic nonlinear schrödger equation.

……

Collect the coefficients of each power and make the coefficients of each power zero to obtain an algebraic equation system about the parameters ai, k, α and use ale to solve this equation system

……2】

Zhuang Weiran was still writing on the blackboard, and many researchers below gradually began to doze off. As time passed, the content on the blackboard became more and more profound and incomprehensible.

Until the end, even academic leaders like Professor Ji and Professor Qian looked at the blackboard blankly, without blinking their eyes, as if they were thinking about something.

"Okay." When he turned around again and looked at everyone, he said with a smile on the corner of his mouth, "I have solved the entire equation system. Do you have any ideas or what you don't understand?"

There are too many things they don't understand, what they need now is not to ask Zhuang Wei but to digest these contents.

"No problem for the time being." Professor Qian pondered for a long time before he said slowly, "We don't have any problems right now, but we don't rule out the possibility of problems in the future."

On such a serious occasion, it is more natural for Professor Qian to call Zhuang Weiran Professor Zhuang, "Professor Zhuang, have you checked the calculation?"

"Before I came here, I did the calculation twice. The final result was made last night, and I checked the calculation after I made it." Zhuang Weiran said with a serious expression, "At least I didn't find it. any mistakes."

"Okay." Professor Qian nodded lightly, "Since Professor Zhuang didn't find any mistakes, let's admit that you have solved the ns equation first. After solving this problem, will it be used in practice?"

"Of course." Zhuang Weiran nodded lightly, "I have solved all the equations of the high-order Reynolds coefficient, and then my research group will use the content I solved to conduct data calculations and experiments on the turbulence model."

"It will take us a while to check this question. I don't think Professor Zhuang will mind?"

"Of course not." Zhuang Weiran said with a smile, "If there is nothing else, then I will leave first. The researchers working in my research group can return to work in the research group now."

He turned and left directly, looking very chic, but the other people in the academic lecture hall seemed a little dull and unbelievable!
