To be sure, every college president wants his or her school to produce gifted students, and the more talented people there are, the better.

Of course, President Du also has this mentality.

At this moment, Cao Zhenggang grandly launched the big day of summer road.

The rest of the first-year students didn't even finish high math and college physics.

As for Xia Lu, he has already completed a paper as the first author.

The project involved in this paper is a national key scientific research project.

The above introduction is from Cao Zhenggang.

Is Xia Lu so magical?

Principal Du's curiosity was stimulated to the maximum.

"Xia Lu, please start your report. Principal Du chose to wait and see what happened.

Xia Lu was already prepared, and he confidently made a statement on the topic: "This report consists of the following parts, in the first part, we use the group theory analysis method to find the generators of the equation and its optimal system.

"In the second part, we reduce the equation and give the exact solution of the equation. ”

"In the third part, we get the adjoint equation and the conservation law of the equation. ”

"In the fourth part, we have carried out a comprehensive integration to create a new method that is different from conventional methods such as the CK direct method, the Buckran transform method, and the Bandlevi truncated expansion method. ”

"Although we used pre-existing theories in the process of proving derivation, we eventually created a new method of NLPDEs that is theoretically feasible and self-sufficient. Our research group believes that the comprehensive application is also an innovation. ”

"Based on this innovative idea, I will report to the leaders one by one according to the above four parts......"

“…… Therefore, after obtaining the full derivative operator, we continue to do the symmetry operation and use the Lie group analysis to obtain all the vector fields of the equation......"

"For specific environments, the symmetric reduction and exact solution of higher-order nonlinear wave equations is a recognized problem in the academic community, and it is also the biggest challenge we face in this topic. ”

He is extremely familiar with this paper presented in the form of PPT, because this paper was written by him.

This PPT is almost entirely full of mathematical and physical formulas, equations and calculus processes, with occasional words.

Xia Lu explained the complex equations on the PPT in his own way, he understood the formulas, equations and calculation process very thoroughly, and explained this esoteric academic topic well with his colloquial expression.

There's a certain amount of technology to this.

If it is a PPT full of text, then anyone can make a report and read it according to the PPT.

Xia Lu's report fully shows that this paper is most likely written by him, at least he wrote most of it.

There is also a possibility that Cao Zhenggang or Yu Feng prepared the manuscript in advance and let Xia Lu forcibly memorize it and perform in front of the principal.

Principal Du listened and fell into deep thought, how much he hoped that the first author of this paper would be Xia Lu, the first author who was really not mixed with water.

Xia Lu continued his report: "We rose to the challenge and overcame this problem by using the power series solution method combined with the Li Qun analysis method......... Eventually, we got this new approach to NLPDEs. After my report, I would like to ask all leaders to criticize and correct. ”

Be quiet.

The site was very quiet.

Although Principal Du and the other judges did not speak, their expressions showed that they had a lot of things to say to Xia Lu in their hearts.

"I'll start with that. President Du was the first to speak, and he said: "If the new NLPDEs method you created is indeed theoretically feasible and self-sufficient, then your research group is a hero of the country." It would be a surprise to me if Xia Lu participated in this project as the first author. ”

"As far as Xia Lu's report is concerned, my intuitive feeling about this new NLPDEs method is that it is more reliable. However, our academic committee still needs to conduct rigorous calculation and analysis verification of this report after the meeting before deciding whether to pass the internal acceptance. I have a question, I want to ask Xia Lu, you go back to the fourth part of the PPT......"

"Yes, that's it, Xia Lu you set the group invariant solution of the equation to ω=f(ξ), then the problem is, you didn't do the coefficient transformation, but used the calculus of this set of Lie group formulas to get the conclusion. ”

"Xia Lu, you just said a word, and I have doubts about this, I need a perfect detailed explanation. Principal Du asked a technical question.

Xia Lu smiled and replied: "If the coefficients are transformed, then when the α=1, β=5, γ=5, and δ=5, the equation becomes the standard SK equation. ”

When α=1, β=30, γ=30, and δ=180, the equation becomes the CDG equation again. If we take α=1,β=-15,γ=-75/2,δ=45, the equation changes again, and it becomes the KK equation. ”

"If we do that, the subject will fall into an endless loop. Because whether it is SK, CDG or KK equations, we will repeat meaningless work such as the CK direct method, the Bucklen transform method, and the Banlevi truncated expansion method. ”

"It's not that the classical equations or methods themselves don't make sense, but that they don't make sense in the specific context of the subject. ”

"So, we used the calculus of Li Qun's formula to break the game. Luckily, we avoided the traps posed by SK, CDG, KK, CK, Backlund, and Painleve, and we got a completely new approach to NLPDEs. ”

"President Du, we did not elaborate on the above reasons in the report, because we believe that there is no need to use the counter-proof method, but it is OK to adopt the direct proof method. If President Du asks us to disprove it first and then prove it directly, then we can revise the report and the thesis. Of course, this would make the paper very lengthy. Xia Lu said his thoughts and reasons, and he thought he had made it clear.

Writing essays is the same as writing novels, and the most annoying thing for authors is to change the text.

Sometimes the authors change and change, and the authors find that the more they change, the worse it gets, and in the end, the whole person is almost autistic, and it is really better to write a new one, so it leads to eunuchs.

Of course, Xia Lu didn't want to change the text, but if the school leader asked him to revise it, he could only obey the leader's decision.

Fortunately, Principal Du is a person who understands, and after listening to Xia Lu's explanation, he stroked his palms and laughed: "No need to change it, keep your plan." I now have every reason to believe that Xia Lu is the first author of this paper, the first author of the real thing, which makes me very excited. I don't have a problem, what about you?"

The "you" in President Du's mouth are several other reviewers, all of whom are senior experts in the field of mathematics and physics.

The experts took turns asking questions, and Xia Lu answered them one by one, and his answers satisfied the experts.
