From Almighty Scholar to Chief Scientist

Although he has graduated now, but some time ago he thought of this problem again, so he thought about whether he should try this most difficult subject, but he didn't expect to encounter difficulties before he had done much, and finally had to give up.

However, such a problem that made it impossible to write, now that Lin Xiao told him that he didn't have much research on mathematical physics, how could he write about things that he couldn't handle at the beginning?

He felt a little incomprehensible.

However, when he opened Lin Xiao's draft paper and the next steps, he was stunned.

"Fyodor-Galerkin approach? And what method is this?"

He suddenly realized that he didn't know what this method was called.

This is probably in a related paper, right?

In fact, Lin Xiao learned about this method when he was listening to a report at the International Conference of Mathematicians, and then he memorized the general theory. When he saw the problem Wang Wei encountered just now, he thought of this method , so it was deduced based on the previous impression and used in this.

However, Wang Wei naturally doesn't know these things. He can only admire Lin Xiao's knowledge in his heart. At the same time, he also wants to ask Lin Xiao where the original paper was written. Akatsuki seemed to be asleep, so he had no choice but to give up.

Then, he turned his head and looked at Lin Xiao's steps. This Fedor-Galerkin approached, "approaching" this difficulty into an easy-to-understand form, which suddenly made him enlightened. Afterwards, Lin Xiao Akatsuki used the Lipschitz continuum, and he already knew this. Anyway, PhD students who study partial differential equations should basically know it.

In this way, after watching for 10 minutes, he read all the steps of Lin Xiao, and then put down the draft paper.

At this time, he could only marvel in his heart, because next, as long as he followed the steps of Lin Xiao to get here, he could continue this subject again.

Although there is no guarantee that there will be problems in the future, but for now, Lin Xiao has solved the biggest problem he faced.

With a wry smile, he murmured, "Students in my class have become my corresponding authors?"

The corresponding author is generally the supervisor of the first author of the paper or the person in charge of the project, including the responsibility for the reliability of the article, and of course, he will also be responsible for guiding the research process of the project.

Obviously, Lin Xiao provided Wang Wei with guidance.

Wang Wei was a little dumbfounded for a while.

Could it be that this is Lin Xiao's compensation for living with him?

"If it really comes out in the future, Lin Xiao must be given a second position."

After thinking about it for a while, as for the position of the corresponding author, of course, it is not easy to give it away, but with the help Lin Xiao provided him alone, the second work must be fine.

Wang Wei stopped thinking about it, turned off the desk lamp, and was about to go to bed.

……

The next day, the military training started as usual. Although it was hard work, it was essential for every student.

Lin Xiao felt that it was acceptable. He swallowed a health capsule at the beginning, and since then his body has been in great shape, just like military training, which is just exhausting.

The only thing that made the students feel uncomfortable was the extremely hot weather in Beijing in September.

The autumn tiger came out of the mountain, causing most people to complain.

Of course, there are some interesting activities during the military training, which can be regarded as a time for the students to relax their bodies and minds. One day, I took them to the army training ground to try shooting at a target. This is also a part of the military training at Beijing University. kind of welfare.

However, time passed quickly like this, and after fifteen days, the military training ended.

Amidst the cheers of the students, the tormented life was finally over, and it was time for Lin Xiao to leave Wang Wei's dormitory.

"Are you going?"

"Ah."

Lin Xiao nodded, and at the same time put his toothbrush and cups into his schoolbag, ready to carry it back to Yanbei Garden.

Although living here for half a month, I have gotten used to it, but it is Wang Wei's dormitory after all. If I really live here, even if Wang Wei doesn't say anything on the surface, he will definitely complain in his heart.

What's more, Lin Xiao felt that it was a pity that he couldn't live in the house of more than 500 million yuan.

Wang Wei stepped forward, helped Lin Xiao tidy up, and said, "By the way, I'm going to write that question into a paper."

"what is the problem?"

Lin Xiao was taken aback.

"It was the night before the military training, the problem I encountered in mathematics and physics, the weakly damped wave equation."

Lin Xiao finally remembered at this moment, and then said with a smile: "That's not bad, has it been resolved?"

"That's not it."

Wang Wei shook his head: "I just have this plan for the time being, and I'm still researching it recently, but it can be done in about half a month."

"Which one do you plan to post by then?"

""MATHEMATICAL-METHODS-IN-THE-APPLIED-SCIENCES", from the second district."

"sure."

Lin Xiao nodded, and being able to post it to the second district shows that the value of the paper is still great.

"At that time, I will put your name on the second work, I hope you don't mind."

At this time, Wang Wei said with a smile again.

Chapter 116 Join the academician's research group?

Lin Xiao was stunned: "Huh? Second work? I didn't do anything."

Seeing Lin Xiao like this, Wang Wei said, "Are you sure you didn't do anything?"

"I just wrote a few steps on it at the beginning, so it shouldn't be a big deal."

"..."

Wang Wei looked at him and remained silent.

"Teacher Wang?...Old Wang?...Ah Wei?"

"OK OK."

Wang Wei sighed and said, "I guess I know what the phrase 'God Lin accepts your supernatural power' said on the Internet means."

"I beg you to reap the supernatural powers."

He was stuck in that place for a month and didn't get it out. Then Lin Xiao got it out after looking at it at night, and then said that he hadn't studied mathematical physics before.

Isn't this bullying the honest person?

"Forget it, I won't tell you any more, I will definitely give you this second work, don't refuse whatever you say, I asked my former mentor the other day, and he said that I have to give you a second work. "

Lin Xiao touched his nose, and could only say, "Then... okay."

Wang Wei: "..."

With your appearance, don't you think you can't see the gold content of the second work of the mathematics journal in the second district?

But thinking about it again, Lin Xiao's first paper was published in a top journal such as "Annual of Mathematics", and the second paper was a report directly at the International Congress of Mathematicians, and it was a one-hour report, even A new conjecture has also been proposed, and related papers have been published in the form of conference papers.

This kind of achievement is no less than that of the "Annual Journal of Mathematics", right?

It is equivalent to Lin Xiao publishing two papers and two TOP journals.

Maybe he really doesn't like his little Second District article.

The more I thought about it, the more I felt that it was a shock. Wang Wei said directly: "That's it, you'd better go and stay with you. I, the counselor, don't even feel like a counselor."

As he spoke, he speeded up and helped Lin Xiao continue to pack his things. At the same time, seeing that Lin Xiao was packing so slowly, he grabbed the schoolbag from his hand and continued to help him pack it up. He also asked: "Do you still want the military training uniform? If not, you can put it in the donation box later, but you have to find a student dormitory, which is usually placed there these days."

Lin Xiao: "...Then donate."

Looking at Wang Wei's speed of packing things, he couldn't help asking, is it the same way to send the second paper now?

He didn't say no...

Soon, things were packed, and there were not many, just two sets of clothes and a book, and nothing else.

For the past fifteen days, because the daily items of the military training were fully arranged, Lin Xiao basically didn't learn anything.

Then Wang Wei said that he would send Lin Xiao off, took him to the school gate, found a donated clothes box by the way, and threw the military training uniform in it.

They got on Wang Wei's small electric donkey, and they set off directly. According to Wang Wei, he bought it when he was studying for a master's degree at Peking University. After graduation, he still stayed in school to work, so the car stayed. years of history.

Soon, at the school gate, Wang Wei put Lin Xiao down and was about to say goodbye when he suddenly remembered something and said, "By the way, you should be more interested in mathematics and physics, right?"

Lin Xiao replied: "I'm still interested. I'm planning to study physics now. I should also study mathematical physics."

"That would be great!"

Wang Wei clapped his hands and continued to ask: "Then are you interested in joining a research on a mathematical physics project? For your mathematical ability, if you are studying mathematical physics, you can directly join a research group and study it. You get used to mathematical physics in advance."

Lin Xiao thought about it for a while, and felt that it was quite reasonable, so he asked, "May I ask what the subject is?"

"It's a subject that my doctoral supervisor applied for before. My doctoral supervisor's name is Tang Qing, and he's already an academician. I don't know if you know, but now he works at the International Mathematics Research Center of Peking University."

"As for the topic of Navierstock equations, I study partial differential equations, and my teacher basically studies partial differential equations, and there are only those issues worthy of research in this area."

"The Navierstock equation?"

Hearing this name, Lin Xiao immediately thought of that. Of course, people in the mathematics world would think of the problem in the seven millennium problems.

Lin Xiao asked tentatively: "It shouldn't be that question, right?"

Seeing Lin Xiao like this, Wang Wei couldn't laugh or cry.

Of course he knew what the 'problem' Lin Xiao was talking about.

The existence and smoothness of the solution of the NS equation, one of the two problems in the field of mathematics, mathematics and physics in the seven millennium problems.

This question is well-known in the field of mathematical physics, and another Yang-Mills gauge field existence and mass interval hypothesis, like two crowns, waiting for scholars in the field of mathematical physics to take it off.

But obviously, they can't be treated as crowns, and it's obviously not so easy to solve. Up to now, most people can only stay away from these two problems, and only a few people dare to try.

And Wang Wei's mentor obviously couldn't run over to study this kind of problem.

He said: "What are you thinking? It's definitely not this thing. It's probably related to two-dimensional incompressible fluids. Let me think about it. The topic seems to be the overall well-posedness of two-dimensional incompressible elastic dynamics. It's quite powerful anyway. If it can be done, it will be a TOP article if you don’t say anything, my teacher has been studying this issue for a long time, so you can rest assured.”

Hearing the name of this project, Lin Xiao was bewildered: "...What is it? What is incompressible?"

"The overall well-posedness of two-dimensional incompressible elastic dynamics is quite complicated if you insist on it, but you don't need to worry about how complicated it is. If you enter it, at most you will be responsible for the mathematical calculation part. Here you You can rest assured."

"It won't be difficult, will it?"

"If it is difficult, it must be very difficult, but if you want to learn mathematics and physics, it is a good thing to participate. Originally, my tutor wanted me to join in, but you also know that I am now your tutor. I can only refuse, and I see that you are also interested in mathematics and physics, so I will ask you."

"OK then."

Lin Xiao thought for a moment, and finally nodded in agreement.

Just like what Wang Wei said, since I am interested in mathematical physics, I might as well give it a try. It is also a challenge for myself, but for the time being, it seems that the difficulty is a bit too much...

"That's good!" Wang Wei immediately showed a smile on his face, and said, "I will tell my tutor your name later, and ask my tutor to agree, but don't worry, my tutor will definitely agree."

"Row."

Lin Xiao nodded. At the same time, it was probably because he decided to participate in this project. He was also interested, and said, "Then you can recommend a few more related books to me. If you don't read any books, it doesn't make sense. .”

"Of course there is no problem with this, I will send it to you later."

Wang Wei made an 'OK' gesture and said cheerfully.

"Okay, thank you."

Lin Xiao nodded, then said goodbye to Wang Wei, turned around and ran to the bus station.

There is no shade at the gate of the school. He and Wang Wei talked under the sun, it was too hot.

Fortunately, when he arrived at the bus stop, the No. 688 bus arrived just in time, so he got on the bus directly and went straight back to his 'luxury' dormitory.

Back in the house, he fell directly on the sofa and turned on the air conditioner.

"This weather is really unbearable."

After a while, I received a message from Wang Wei.

"My instructor agreed, I will send you his prestige signal later, you can just add him, he is quite surprised that you came to participate in the project"

Lin Xiao frowned and replied, "Okay. 』

"1234..."

Then Wang Wei directly sent a series of numbers, which should be the prestige signal of Academician Tang Qing.

『In addition, the research is on the Navierstock equation. I recommend you to read these books first. The first is the book on fluid mechanics. For the Chinese one, read "Fluid Mechanics". After reading it, you can basically understand it completely. What is the Navierstock equation? Of course, I am referring to the physical sense and the mathematical sense. I guess I am not as thorough as you.』

"Just watch the English version..."

Then, Wang Wei recommended a lot of books to Lin Xiao. After Lin Xiao read it, it seemed that he had to make up for what he had next.
