From Almighty Scholar to Chief Scientist

Chapter 119 The Surprise Brought by Lin Xiao

After introducing Lin Xiao, Tang Qing specially introduced other people to Lin Xiao, first of all, a professor from the Academy of Physics named Cao Chengqing.

As for the other young people who are slightly younger, they are Tang Qing's graduate students and postdoctoral fellows here.

After getting to know each other once, Tang Qing said, "Okay, there's no need to say anything else. Since we're all here, let's start this group meeting now."

"Lin Xiao, have you held a group meeting before?"

"No." Lin Xiao shook his head.

"Oh? Then all your previous achievements were independently researched by yourself?"

"Yes."

"That would be great."

Tang Qing nodded, and the others were also a little surprised. It is really amazing to rely on one person to independently research those important results.

"Then since this is your first group meeting, you can just take a look at it first. Oh, by the way, there is still a project cooperation agreement that needs to be signed by you. It is mainly about the confidentiality of the research content of the project. You should know this Bar."

After speaking, Tang Qing took out an agreement from the briefcase next to him and put it in front of Lin Xiao. Lin Xiao naturally signed the agreement without any doubts.

After that, the group meeting officially started.

The research group will report their respective progress, and make a PPT to share, to tell other members about their achievements, and to avoid people being lazy.

So first of all, those young people walked up and began to share their work from the previous week.

After all, young people like them are not as knowledgeable as their tutors, and they generally can't provide any useful help in the main direction of the subject, so they usually do document sharing at most, helping tutors and other highly qualified and knowledgeable people Provide something that can be used.

And Lin Xiao was quite interested in listening to their report.

From time to time, I can see some high-end things just because of the title, such as "The Zero Condition of the Quasilinear Wave Equation in Two-Dimensional Space", and "The Integral Existence of Nonlinear Elastic Waves".

These documents can also help them with this topic.

And as they shared, Tang Qing and another professor also listened and discussed. If something was useful, they would be impressed by it, and then write down the relevant things.

Soon, the postgraduate sharing was over, and Tang Qing and the two professors began to discuss the deep-seated issues of the subject. They stood in front of the blackboard, wrote down a few formulas on it from time to time, and discussed, while other young people Listening around, absorbing the knowledge spoken by the instructor.

Tang Qing stroked his chin and looked at a formula written on the blackboard in front of him.

【(t)ΓαY...(t+r)DΓαY】

"We need to estimate a weighted L2 generalized energy norm," he said.

"Yes." Cao Chengqing nodded, based on Tang Qing's formula, he wrote a few more lines later, and then said: "But obviously there is a problem here, we have to control the weighted generalized L2 energy according to the generalized energy Eκ Xκ."

"Um……"

Tang Qing suddenly took the blackboard pen and wrote a formula on it.

【r(t)Y】

Then he said: "Then let's estimate the r-weighted zero shape of this thing?"

Cao Chengqing looked at it, his eyes lit up.

Tang Qing said, "You can give it a try."

Then, they started to move their hands.

Of course, they did it on scratch paper, after all, the blackboard is limited.

Watching the three professors' hands-on work, several graduate students also thought about it, and also wanted to try to estimate this r-weighted zero shape.

However, Lin Xiao stared at the formula on the blackboard.

He has his own unique thinking about this kind of thing that is already in mathematics.

After thinking for a while, he took the pen in his hand and started writing on the draft paper.

Although he has not made any outstanding results in partial differential equations, this does not prevent his mathematical skills in this area from being still strong.

Everything is always the same, after all, it is a game of numbers and logic, especially Lin Xiao's current brain development rate has reached 3.65%, which is gradually approaching the situation when he was using the sage at the beginning. Level 3, at this time, he already has an intuition about mathematics that is difficult for ordinary people to understand.

So after writing down a few calculations, he frowned and said softly, "This won't work."

When everyone was thinking about the problem, although his voice was relatively soft, it was still quite obvious. When the others heard it, they couldn't help but look at him.

"It won't work?"

Tang Qing asked a question.

When Lin Xiao said this, he obviously denied his proposal.

However, he wasn't angry either. This is the case with research projects. No one makes mistakes, which is obviously abnormal. Only by making mistakes constantly can they continue to succeed.

Of course, to make an error, you also need to explain the reason.

Therefore, he also waited for Lin Xiao to give the reason why this direction did not work.

Tang Qing also said, "Tell me what you think."

"Because r is not in the class Ap of the zero-order Riesz operator with p equal to 2 in two-dimensional space."

Lin Xiao directly stated the reason.

Hearing Lin Xiao's words, Tang Qing and Cao Chengqing were stunned.

"p is equal to 2?"

Tang Qing muttered, then wrote something on the draft paper, and then his eyes were fixed: "Yes...it is indeed the case. In this way, we cannot directly estimate the r-weighted zero shape."

Cao Chengqing also nodded.

After Lin Xiao reminded them, they immediately realized the problem.

Although it doesn't mean they can't find out, but the problem is, if Lin Xiao didn't bring it up, God knows how much time they would spend on it.

However, it took less than 5 minutes for Lin Xiao to point out that this road would not work, which made them feel admirable.

"sharp."

Tang Qingchao gave Lin Xiao a thumbs up.

Before Wang Wei introduced Lin Xiao, the reason why he agreed was because he liked Lin Xiao's potential and cultivated a relationship with Lin Xiao. He also didn't think about how much help Lin Xiao could provide.

After all, in the eyes of everyone, Lin Xiao is destined to develop in number theory. After all, he has shown such a powerful talent in number theory, and number theory is enough for a mathematician to study for a lifetime. Most famous Most mathematicians have specialized in one direction all their lives.

And a hammer to the east and a stick to the west is obviously a waste of talent. Even Tang Qing is planning to spend a while, waiting for Lin Xiao to waste time in their research group, and then warn him to concentrate on one task. research in the field.

But right now, it seems that he is still underestimated.

His mathematical talent seems to be very helpful to their research on this subject of mathematical physics.

Professor Cao Chengqing also praised: "That's right, I really deserve to be a mathematical genius."

As for the other graduate students and postdoctoral fellows, they can only express their admiration at this time. No matter what, they are geniuses. Even if they do not specialize in partial differential equations, even if they understand it, it is not something they can question.

However, in the face of the appreciation of the two seniors, Lin Xiao just said modestly: "Actually, that's it, mainly because it is about mathematics, and I can understand it. If it involves physics, I really don't understand it." There is a way."

"Hehe, don't belittle yourself."

Tang Qing waved his hand and said, "Then it seems that our previous direction was wrong, and we need to think about a new direction."

"Ah."

Cao Chengqing nodded, thinking again.

Although the previous direction was wrong, it is enough to change the direction and think again. The problem is not big, anyway, as long as it can be corrected in time.

After all, when researching a topic, the most fearful thing is not encountering problems, but fearing that there will be no problems.

In order to achieve the final goal, the intermediate steps need to be divided into small problems one by one, and then until the last step, but if you don't even know what the problem is, then it's over.

That's like not even knowing in which direction to exert force.

However, just after they lowered their heads for a while, Lin Xiao spoke again.

"Let's change to another one to estimate."

"Ok?"

The two professors who just lowered their heads immediately raised their heads again. Did this Lin Xiao come up with another method?
Lin Xiao stepped forward and said, "Can I use a pen?"

"Give you."

Tang Qing handed the blackboard pen to Lin Xiao, wanting to see what kind of surprise Lin Xiao could bring him again.

After taking the pen, Lin Xiao directly wrote down a formula on the blackboard.

【(t)Y】

"We don't need to estimate the previous thing, we just estimate it."

Looking at what Lin Xiao wrote, Tang Qing frowned: "Continue to talk."

"We define this weighted L2 generalized energy as..." Lin Xiao began to write the following formula on the blackboard.

[Xκ=∑|α|≤κ2(∫……]

As Lin Xiao wrote down the line-by-line formulas, the eyes of the two professors became extremely serious, quietly watching Lin Xiao's calculations, and at the same time, they were also doing the calculations with their hands.

Tang Qing's graduate students could understand it at first, but they became more and more confused as they went on.

What are they talking about...

Is their graduate student in mathematics at Peking University studying for nothing?

I wanted to ask something, but seeing the two professors listening carefully, and seeing the postdoctoral seniors next to me also thinking hard, they could only give up and ask later.

In front of the blackboard, after Lin Xiao wrote down the last few lines of the formula, Tang Qing finally couldn't help but said, "Wonderful!"

Cao Chengqing couldn't help applauding.

The mathematical method used by Lin Xiao directly and perfectly answered their questions.

Now, with Lin Xiao's key step, they have successfully estimated the L2 generalized energy norm.

　Ask for a monthly pass.
