Chapter 325

Three days later, the Mathematics and Science Innovation Practice Base of Peking University.

Five mathematical geniuses from five universities gathered here again.

Professor Zhong Yongan did not come this time, and there were only five of them in the office.

"Since Professor Zhong said that the project this time is to be entrusted to the five of us, then let's sit down and discuss some detailed rules?" Wei Jun, a doctoral student at Peking University, said with a smile.

Among the five, Wei Jun was barely half the host, and the other four also nodded and sat at the long table in the middle of the office.

The position of the main seat, I am afraid that the current situation is still confusing, and no one will go back to sit. So five people sat on either side of the long table with three on one side and two on the other.

This is how the first meeting of the inter-university joint project began.

The five of them don't know each other, and maybe even some of them met in person yesterday and only knew that there was such a number one. For example...... Cheng Nuo.

In short, the atmosphere at the conference table was very delicate, and for a while, no one spoke, and everyone looked down at the documents in their hands.

Ahem......

In the end, the guards couldn't watch the atmosphere go on like this, so they had to be the first to speak, "In this case, I'll say some of my opinions first, which can be regarded as throwing bricks and stones." ”

He pulled out a document from his hand, and his gaze suddenly became serious, "This is a project structure framework made by me three days ago after I went back and took the document given to us by Professor Zhong and read it back, according to my own understanding. ”

Wei Jun opened the file, bowed his head and said, "The name of the topic we are working on is called: Nonlinearization of the Darboux Transform Based on the Kaup-Neell Equation of Constrained Flow. ”

"From the point of view of the branch of research, this is a topic in the field of geometry. Wei Jun smiled, "And the direction of my main attack is geometry, so I still have some opinions on this aspect, a few of you can listen to it." ”

The (1 + 1) method for the spectral nonlinearization of dimensional soliton equations was first proposed by Cao in 1988. According to his book "Discrete Line Spectrum 2N Visin Manifold", a continuous linear spectral problem can be nonlinearized to generate a finite-dimensional fully integrable Hamilton system......"

Although Wei Jun's lectures were all professional content in the field of geometry, they were not very advanced or obscure, and the other four could easily follow his train of thought.

Wei Jun has been specializing in geometry since his graduate studies, and he has been doing it for almost five years now.

In the past five years, Wei Jun has learned not only some professional knowledge, but also some unique insights accumulated from experience.

“...... For the Kaup-Neell equation, pt=-1/2pxx-2(qp^2)x, qt=-1/2qxx-2(pq^2)x...... Therefore, I think that if we use the Backlund transform that constrains the flow of the Kaup-Neell equations, we can find that ∑N,j=1d?1j^d?2j=∑N,j=1dφ1j^dφ2j, thus generating two integrable mappings with different variables!"

It took about five minutes for Wei Jun to explain his own opinion.

Over there, Sheng Fei from Jiangsu and Zhejiang University couldn't wait to stand up and hold Wei Jun's hand when he saw Wei Jun finish speaking, "Sure enough, the hero sees the same thing." ”

Sheng Fei picked up one of his folders and said with a smile, "The ideas that Wei Jun's classmates talked about are almost the same as mine. ”

"Oh?" Saying this, Wei Jun also became curious, "Classmate Sheng, can you show me." ”

"No problem. Sheng Fei smiled and handed the document to the guards.

On the seat of the guard, he lowered his head and swept Sheng Fei's documents in two or three minutes, and then handed it back to Sheng Fei with a smile, "Sure enough, the framework of the project constructed by Sheng and my classmates is much the same, and the main aspects are basically the same. ”

"Three, do you have anything you want to say?" Wei Jun looked at Cheng Nuo and the three of them, who had not yet spoken.

Yang Xiao of Jiangsu and Zhejiang University shrugged his shoulders and smiled, and waved his hand, "I'm not as good as the two of you, I can construct the framework of the subject in three days, and I can't learn this operation." Since both of you have the same idea, then I will not add to it, and just follow the framework of the two of you. ”

Yi Ge, the only girl among the five, also blinked innocently, stuck out her tongue, and said embarrassedly, "A few days ago, I just went out to play crazy with a friend in Kyoto, so ...... However, don't worry, this is definitely the last time, and even though you have assigned me the task, I will definitely do my duty and complete it with quality and quantity!"

Well, it seems that this girl Yige is playful and hasn't found the time to build the framework, and I'm afraid I don't even have a full understanding of the specific content of the topic.

None of that matters now, though.

After hearing Yi Ge's words, Wei Jun's heart was slightly happy.

In this case, Cheng Nuo is the only one who has not asked for personal opinions.

After going back a few days ago, he inquired with a friend from the Department of Mathematics at Tsinghua University and learned that Cheng Nuo's true identity was just a freshman in the Department of Mathematics at Tsinghua University.

Although he heard that Cheng Nuo had participated in the research of three topics, this was not a reason for Wei Jun to put Cheng Nuo on the same level as himself.

In terms of resume, he has participated in research projects of no less than 10 large and small projects, and this is the first time he has the opportunity to participate in an inter-university cooperation project.

As for Cheng Nuo, although some dry goods in his stomach are good, Wei Jun would never believe that a freshman student could stand on the same level as their four doctoral students.

"Classmate Cheng, what do you think?" Wei Jun turned his head to look at Cheng Nuo as if he was doing a routine business, and asked with a smile.

He doesn't mind taking a paddling guy, after all, an undergraduate, it's not bad to have him or not.

It's just that, in the same way, he doesn't think that Cheng Nuo will give anything to make a difference.

"Ah, you ask me?" Cheng Nuo, who seemed to be outside the spirit, was clever and asked with a confused expression.

This guy ...... You can't just be distracted, right?

Wei Jun thought speechlessly.

He said patiently, "I want to ask if there is a problem with the topic framework I just mentioned, Cheng Nuo thinks." If not, we will follow that framework. ”

The guards changed their words again.

He didn't expect Cheng Nuo, the guy who was still distracted just now, to say even something meaningful, but he just hoped that Cheng Nuo would quickly give a yes or no answer.

Cheng Nuo smiled without hesitation, "Senior Wei, the framework you just said really doesn't have any mistakes. ”

Wei Jun's face was happy, "Then we will ......"

"Hey, wait. Cheng Nuo raised his hand and said with a smile, "I'm sorry, I haven't finished my sentence yet." ”

"Wrong, not at all. However, don't you think that this framework is too complicated?" Cheng Nuo said with a smile.
