Chapter 307

there are two senior students in the second postgraduate study, one is called Zhang Chumen, the other is Gu Shi.

Both of them are direct students of Professor Fang, and they have followed him since the undergraduate stage.

Moreover, both of them were directly insured because they had achieved enough achievements at the undergraduate stage.

"Teacher, is this?" Entering the door, Zhang Chumen glanced at Cheng Nuo and asked with a smile.

"Oh, he is the classmate Cheng Nuo introduced by Professor Lu, who is going to join our research group. In the next six months, Cheng Nuo will be one of our members. You should take care of him more." Professor Su introduced it with a smile.

"Hello, my name is Cheng Nuo." Cheng Nuo reaches out his hand.

"Zhang Chumen."

"Look after the world."

Gu Shi Xuechang is very cold, holding his arm, just nodding to Cheng Nuo, looking like a world expert.

Zhang Chumen was very enthusiastic and shook hands with Cheng Nuo.

In terms of age, Zhang Chumen is four or five years older than Cheng Nuo, but he has no shoulders.

He patted his chest, "Cheng Nuo, don't worry. The teachers have spoken, and they are all from the same college. If you have any problems in the future, you can go to the graduate dormitory directly and find me."

Cheng Nuo said thank you, indicating that he took this feeling.

Just then, Su Xuanqi came out of the kitchen with a dish.

She put a plate of sweet and sour spareribs on the tea table, wiped the sweat on her forehead, crossed her waist, and said to Cheng Nuo, who are still standing, "what are you doing here? Sit down and have a meal."

The three were hesitant.

Professor Fang asked the three people to sit down with a smile, "knowing that you are coming, I asked Xiaoqi to cook more dishes. Let you run over at noon, you must not have time to eat. It's just right. We'll eat and talk. "

The three looked at each other and sat down one after another.

After serving all the dishes, Su Xuanqi and Professor Fang sat on the other side of the sofa.

A few people chatted while eating. Naturally, it was about the project.

Zhang Chumen said with a smile, "teacher, should the name of our project be decided?"

The answer is Su Xuanqi, "the teacher told me that the name of this subject is called monotonicity method for Bi typical nonlinear differential equations with generalized p-Laplacian operators."

"Monotone methods for Bi typical nonlinear differential equations with generalized p-Laplacian operators?" Cheng Nuo murmured.

"Do you feel confused? Ha ha, to tell you the truth, if I heard the name of this project when I was not a graduate student, I would definitely be confused. But now, that's how it feels Zhang Chumen, sitting on the side of Cheng Nuo's body, pretended to be forced in front of his younger brother who met for the first time.

Cheng Nuo shrugged, "OK."

In fact, after Professor Lu's project, Cheng Nuo went back to have a deep understanding of this knowledge.

The more you know, the more you know, the more you know why this research project is so important in all the colleges and universities.

The generalized p-Laplacian operator and the zero point of maximal operator are indeed the hot spots in the international research nowadays. It is good that the applied mathematics field in China has also followed this upsurge and carried out many projects, and the papers on this field are also one after another.

However, to be honest, there are very few subjects and papers about this aspect in China. As for the results that can be put into the international mathematical community to let the whole world learn, it is rare.

Therefore, Tsinghua University and Peking University jointly applied for this project, which represents the most advanced direction of p-Laplacian operator.

Of course, the most cutting-edge issues also mean that there is not much information to refer to. Everything depends on our own groping.

The burden is very heavy, especially for Cheng Nuo, who is still in the undergraduate stage.

Of course, fortunately there is Professor Fang's thick thigh.

Five people eat and talk.

"Our subject, simply put, is to use the perturbation results of the range of pseudo monotone operator and maximal monotone operator to obtain the abstract conclusion that there exists unique solution for hyperbolic nonlinear differential equation with generalized p-Laplacian operator and mixed boundary value conditions."

This is a generalization of the research work on Nonlinear Elliptic Equations and parabolic equations with generalized p-Laplacian operators, and the relationship between the unique solution of motion and the zeros of some maximal monotone operator is also discussed. Of course, I can't give a final conclusion on some of my conjectures and the methods to be used in the actual operation of these knowledge. " Professor Fang first briefly explained the main research contents of the project.

Then, let a few people express their own opinions and say their own opinions.

To be honest, none of the four is an expert in this field.

Although the three graduate students are majoring in the field of correspondence, applied mathematics is divided into many research directions. None of their research directions is about p-Laplacian operator, and they have a little knowledge about this aspect.Of course, their kind of slightly involved refers to the degree to which the full score of the exam is no problem, and the research on new content is somewhat difficult.

Talking about some superficial things, the three people are still very relaxed.

Starting from Su Xuanqi, the three people have expressed their own unique views on this topic. They talked about a lot of formulas and theorems, but they did not specifically discuss the more in-depth issues.

To the last Cheng Nuo, several eyes all fall on him.

Cheng Nuo laughed and slowly opened his mouth, "I don't know much about the professional knowledge in this field. I'll talk about the research direction I think about this topic. Of course, this is just my guess. I can't guarantee whether it can be implemented

"It doesn't matter. Just talk freely. It doesn't matter if you say it wrong." Professor Fang gave Cheng Nuo an encouraging look.

Cheng Nuo coughed and organized his language. "I think that this topic, our starting point, should be put on the Banach space."

Cheng Nuo's tone is indescribable.

"Banach space? Isn't that in functional analysis? It has something to do with our subject? " Gao Leng's elder Gu Shi frowned and opened his mouth.

"Let Cheng Nuo continue to say that mathematics is the subject of mutual penetration, there is no strict division of fields." Professor Fang motioned Cheng Nuo to continue.

Cheng Nuo continued, "it is true that Banach spaces and maximal monotone operators do not have much correlation. However, through the calculation of some formulas, they are related to each other."

"If Ω is a compact Hausdorff space and C (Ω) is the whole of all real (or complex) valued continuous functions over Ω, then C (Ω) becomes a Banach space with respect to norm. If (Ω, μ) is a positive measure space, let LP (Ω, μ) denote all summable functions of degree p (P ≥ 1) on Ω, then LP (Ω, μ) becomes a Banach space with respect to norm... "

Cheng Nuo talks.

A string of formulas blurted out without thinking.

Gu shisan said they were completely confused.

Only Professor Fang was able to keep up with Cheng Nuo's ideas.

Besides, Professor Fang nodded frequently while listening.
