Chapter 322 (1/2)

In Chapter 325, three days later, Peking University Mathematics and science innovation practice base.

Five mathematical talents from five universities have come together again.

This time Professor Zhong Yongan did not come. In the office, there were only five of them.

”Since Professor Zhong said that the subject was given to us five full powers, we would sit down and discuss some details in detail?” The doctoral guard of Peking University took the lead in opening and laughing.

Among the five, the guards were barely half the hosts, and the rest four nodded and sat on the long table of the meeting in the middle of the office.

I'm afraid the situation is still uncertain about the position of the Lord. No one will go back to sit. So five people sit on both sides of the long table, three at one side and two on the other.

The first project meeting of the joint project of cross school began with such a situation.

Five people can not call each other know each other, perhaps even some people, are yesterday personally met, only know that there is such a number of people. For example Cheno.

In short, the atmosphere on the table was delicate, for a while, no one spoke, looking down at the documents in their hands.

Cough

Finally, the guards could not look at the atmosphere so rigid, so they had to first say, ”then, I will say some of my views, it is a brick to start.”

He took a document from his hand and his eyes suddenly became serious. ”It was a framework of the project structure made by me after I went back to take the document Professor Zhong gave us back to us three days ago and looked at it again

The guardian opened the file and said, ”the name of the subject we studied, called the nonlinearity of Darboux transformation of the Kaup Newell equation based on the constrained flow.”

”From the perspective of research branch, this is a subject in the field of geometry.” The guard smiled, ”and the direction I am mainly focused on is geometry, so I still have some opinions on this aspect, and some can listen to it.”

The nonlinear method of spectral problems for the (1 + 1) dimensional soliton equation was first proposed by Cao in 1988. According to his account in the ”2n dimensional manifold of discrete line spectrum”, a continuous linear spectrum problem can be nonlinear to generate a finite dimensional completely integrable Hamilton system... ”

Although all the professional contents of geometry are described by the guardian, they are not so deep or remote. The rest four can easily follow his ideas.

The guards have been specialized in geometry since their graduate school, and it has been almost five years since now.

In five years, the guards learned not only some professional knowledge, but also some unique insights accumulated from experience.

“…… For Kaup Newell equation, pt=-12pxx-2 (qp^2) x, qt=-12qxx-2 (pq^2) x Therefore, I think if we use the Backlund transformation which constrains the flow of Kaup Newell equation, we can find that σ n, j = 1D? 1j^d? 2j= ∑ n, j = 1D φ 1j^d φ 2J, thus generating two integrable symplectic maps with different variables! ”

The guards spent about five minutes explaining his own views.

Over there, Sheng Fei from Jiangsu and Zhejiang University saw the guards finish, and they could not wait to stand up and hold the hand of the guard. ”It is indeed the same as the hero.”

Sheng Fei picked up his own folder and smiled, ”the thoughts that the guardian students are talking about are almost the same as mine.”

”Oh?” So, the guard also came to curiosity, ”Sheng classmate, can you show me your.”

”No problem.” Sheng Fei smiles and gives the documents to the guards.
