Chapter 117 Join the academician’s research group?

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

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

"I just wrote a few steps on it, so it shouldn't be anything."

"..."

Wang Wei looked at him and said nothing.

"Teacher Wang?...Old Wang?...Awei?"

"OK OK."

Wang Wei sighed and said: "I finally know what the saying on the Internet, 'Lin Shen takes away your magical powers,' means."

"Please take back your magical powers."

He was stuck in that place for a month and couldn't figure it out. Then Lin Xiao looked at it at night and figured it out. Then he said that he had never studied mathematical physics before.

Isn’t this bullying an honest person?

"Forget it, I won't tell you any more. I definitely have to give you this second title. Don't refuse no matter what. I asked my previous mentor that day, and he said I have to give you a second title. "

Lin Xiao touched his nose and said, "Then...okay."

Wang Wei: "..."

With your appearance like this, don’t you think you still look down on the value of the second work of the Second District Mathematics Journal?

But then I thought about it, Lin Xiao's first paper was published in a top journal like "Annals of Mathematics", and his second paper was a report directly at the International Congress of Mathematicians, and it was a one-hour report, even A new conjecture was also proposed, and related papers have been published in the form of conference papers.

This kind of achievement is no less than that of "Annals of Mathematics", right?

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

Maybe he really doesn’t like his little second-district article.

The more he thought about it, the more offensive he felt. Wang Wei said directly: "That's it, you should leave quickly. Staying with you will make me, a counselor, feel like I am no longer a counselor."

As he said that, he speeded up and helped Lin Xiao continue to pack his things. At the same time, he saw that Lin Xiao was packing so slowly, so he grabbed the schoolbag from his hand and continued to pack it for him. 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. They are usually kept there these days."

Lin Xiao: "...then donate it."

Seeing how quickly Wang Wei packed up his things, he couldn't help but want to ask, is this the way to send two papers now?

He didn't say no...

Soon, things were packed, and there wasn't much, just two sets of clothes and a book, but not much else.

In the past fifteen days, Lin Xiao had basically learned nothing because the military training was fully scheduled every day.

Then Wang Wei said he wanted to see Lin Xiao off and sent him to the school gate. He also found a box for donating clothes and threw the military training uniform in.

After getting on Wang Wei's small electric donkey, they set off directly. Wang Wei said that he bought it when he was studying for a master's degree at Peking University. After graduation, he stayed at the school to work, so he kept the car and owned it several times. years of history.

Soon, when he arrived 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 am still interested. I am now preparing to study physics. I should also study mathematical physics."

"Then this would be perfect!"

Wang Wei clapped his hands and continued to ask: "Then are you interested in joining the research on a mathematical physics topic? For your mathematical ability, if you are studying mathematical physics, it can also help to directly join a research group to do research. You should get used to mathematics and physics in advance.”

Lin Xiao thought for a while and felt that it did make sense, so he asked, "What is the topic?"

"This is a topic that my former doctoral supervisor applied for. My doctoral supervisor's name is Tang Qing. He is already an academician. I don't know if you know this, but he now works at the International Mathematics Research Center of Beijing University."

"As for the topic of the Navierstock equation, I study partial differential equations, and my teacher basically studies partial differential equations. There are only those issues worth studying in this area."

"Navistock's equation?"

Hearing this name, Lin Xiao immediately thought of that. Of course, people in the mathematical community would think of that question among the seven millennium problems.

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

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

Of course he knew what ‘that problem’ Lin Xiao was talking about.

The existence and smoothness of solutions to NS equations are one of two questions in the field of mathematics and physics among the seven millennium questions.

This question is famous in the world of mathematical physics. Together with the other hypothesis of the existence of the Yang-Mills gauge field and the mass separation hypothesis, they are like two crowns, waiting for scholars in the world of mathematical physics to take them off.

But obviously, they can not be treated as crowns, and it is obviously not that 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 go over to study this kind of problem.

He said: "What are you thinking of? It's definitely not this. It's probably a problem related to two-dimensional incompressible fluids. When I think about it, the topic seems to be the global well-posedness of two-dimensional incompressible elastic dynamics. Anyway, it's pretty awesome. If it can be done, it will be a TOP article if you don't say much. My teacher has been studying this issue for a long time, so you can rest assured."

Hearing the name of this topic, Lin Xiao's face showed confusion: "...What is it? What is incompressible?"

"The overall well-posedness of two-dimensional incompressible elastic dynamics is quite complicated to say the least, but you don't need to worry about how complicated it is. Once you get in, you will at most be responsible for the mathematical calculation part. You are the most important here. You can rest assured.”

"It won't be difficult, right?"

"If it's difficult, it's definitely quite difficult, but if you want to learn mathematics and physics, it's a good thing to participate. Originally, my tutor wanted me to join in, but as you know, I'm your tutor now I am a member of the Communist Party of China, and I am very busy since school started, so I can only refuse. Then I see that you are also interested in mathematics and physics, so I will ask you."

"Oh well."

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

Just like 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 this 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 for my tutor's consent, but don't worry, my tutor will definitely agree."

"OK."

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

"Of course that's no problem, I'll 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 stop.

There was no shade at the school gate. He and Wang Wei were talking under the sun, and it was too hot.

Fortunately, when he arrived at the bus station, bus No. 688 also happened to arrive, so he got on the bus and went straight back to his 'luxury' dormitory.

When he returned to the house, he fell directly on the sofa and turned on the air conditioner.

"This weather is really unbearable."

After calming down for a while, I received a message from Wang Wei.

"My instructor agreed. I will send you his authority signal later. Just add him. He is quite surprised that you came to participate in the project."

Lin Xiao raised an eyebrow and replied: "Okay." 』

"1234..."

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

"In addition, I am studying the Navierstock equation. I recommend you to read these books first. The first is the book on fluid mechanics. For Chinese, just read "Fluid Mechanics". After reading it, you will basically have a complete understanding. What is the Navierstock equation? Of course, I mean it in a physical sense and a mathematical sense. I guess I’m not as clear as you.”

"Just watch the English version..."

Then, Wang Wei recommended a lot of books to Lin Xiao. Lin Xiao took a look and it seemed that he would need to make up for what he had next.

However, thinking about the research group he was about to participate in, he became full of motivation again.

After returning from the International Congress of Mathematicians, he has not thought about those difficult mathematical problems. At most, he usually reads papers in top mathematics journals, or looks at what those who study Lin's conjecture are currently discussing.

My brain has been resting for more than a month.

Now is the time to start operating again and leave the comfort zone.

"I understand, thank you. 』

"Well, these books can be found in the library, so let's do this for now, and come back to me if you need anything later. 』

…

The final draft of the paper is due on the 22nd, and I haven’t finished the first draft yet…

So the amount of updates will really decrease in the future, I hope you understand, but I will try my best to keep it at 8K words every day, and the minimum will not be less than 6K.

【Please give me a monthly pass o(╥﹏╥)o】
