Chapter 334 Xu Chuan: I Don’t Really Know Much

In Shuimu University, Xu Chuan walked on the asphalt road shaded by green trees.

After finding Xu Xiao's phone number, she called her.

The bell rang for a moment and then the call was answered.

"Brother! You actually called me?" Xu Xiao's surprised voice came over the phone.

Xu Chuan smiled and said, "Why, I can't call you?"

"Of course! I am your cutest sister!" Xu Xiao said confidently.

Xu Chuan smiled and said, "Do you have time now? I'm at your school and come to see you."

"Really?" Xu Xiao asked in surprise.

"Why are you lying to me? I'm having a meeting here in the capital these two days, so I came over to see you." Xu Chuan said with a smile.

Xu Xiao: "Well, it turns out I was just along for the ride! Humph!"

The corner of Xu Chuan's mouth twitched: "Don't be poor, I'm at the basketball court near the biology building now."

Xu Xiao: "Brother, can you wait for me? I'm doing experiments in the laboratory right now. I can't leave, so just wait a minute!"

Xu Chuan asked curiously: "Aren't you just a sophomore? Why did you enter the laboratory?"

"Of course it relies on intelligence! Don't underestimate your sister, I have already completed all the undergraduate content! I will be able to enter graduate school next year!" Xu Xiao said arrogantly.

Xu Chuan smiled and said, "Okay, how long do you have to wait? If it takes longer, I'll go shopping around first."

"About half an hour to an hour. Brother, please take a walk first. I'll call you when I'm done!"

Xu Chuan smiled and said, "Okay."

After hanging up the phone, Xu Chuan glanced at the biology building not far away, and felt a little curious.

Xu Xiao actually entered the laboratory in her second year of college. She may not be at a low level, maybe with her tutor, but at least it shows that she has made some academic progress.

But where is the best place to go for a stroll?

Looking around, Xu Chuan thought for a while and decided to go to Professor Qiu Chengtong's place.

Mainly because he didn't know any other familiar people here at Shuimu University.

Along the tree-lined path, Xu Chuan came to Qiu Chengtong Mathematics Center.

He found Qiu Chengtong's office. Although the door was open, he still knocked on the office door.

Hearing the sound, Mr. Qiu, who was sitting at his desk calculating something, raised his head.

When he saw the person appearing at the door, he was stunned for a moment, then stood up with a smile and welcomed: "Hey, you are a rare visitor. What kind of wind brings you here?"

Xu Chuan smiled and said: "Come here for a meeting, and come here to see my sister, but that girl is in the laboratory now, so I just wanted to come and sit with you."

Mr. Qiu smiled and said, "Welcome."

As he spoke, he stood up and made tea: "Congratulations, you will be called Academician Xu from now on. The titles of academicians of the two academies are awarded in the same year. You have broken another historical record."

Xu Chuan smiled and said: "I was a little surprised. I thought I could only get one from the Academy of Sciences, but I didn't expect that the Academy of Engineering would also apply."

Qiu Chengtong smiled and said: "You deserve the title. Your contribution to the fields of batteries and nuclear energy is enough."

After chatting for a while, Qiu Chengtong took a sip of tea and said with a smile: "It's better to come by chance than by chance. It just so happens that I have been studying a problem these two days and have encountered some troubles. Can you help me?"

Hearing this, Xu Chuan was a little curious and said, "Oh? Which aspect?"

Qiu Chengtong put down his tea cup, stood up, picked up a stack of manuscript paper from his desk, and handed it over.

Xu Chuan took the manuscript paper and turned it over. The calculations and equations on the paper made his eyes show a look of interest.

After a while, he raised his head and looked at the old man in front of him, and said with a smile: "Mr. Qiu is really as strong as ever. He is as wise and brave as ever. He actually advanced the KZB equation to this point."

With his mathematical ability, he couldn't say that he could fully understand the calculations and equations on the manuscript paper, but he could at least get a rough idea.

It has to be said that Qiu Chengtong is indeed a top expert hailed as the "Emperor of Mathematics" by Harvard University.

In his early seventies, he is still studying world-class problems, and he still has the ability to take a big step forward.

The so-called KZB equation is a top problem in mathematics. It is derived from the KZ equation and connects vertex operator algebra, representation theory, Riemannian geometry and other branches of mathematics.

KZ was originally proposed by two mathematicians, Knizhnik and Zamolochkov. Later, Professor Bernard extended the KZ equation to the more general Riemann surface, which is the so-called KZB equation.

To put it simply, the KZB equation and the NS equation are somewhat similar. Both of them gain more relevant things when studying this equation.

The NS equation is fluid mechanics, while the KZB equation is the thermonuclear equation and index theorem.

Hearing Xu Chuan's praise, Qiu Chengtong smiled and said, "It's just a hobby in my spare time."

Xu Chuan gave a thumbs up, he was convinced by this β pretense!

Very mellow.

After smiling, Qiu Chengtong continued: "Speaking of which, this has something to do with you."

"While studying this, I once read the proof paper of the Weyl-Berry conjecture that you studied. In it, you provided me with some inspiration by constructing the counting function associated with the fractal drum."

"In the second part of the manuscript in your hand, I defined and studied a special subclass of global and formal elementary spherical functions, called global and formal n-point spherical functions."

"When the position variable tends to infinity, the limit of the related function of the boundary Wess-Zumino-Witten conformal field theory on the cylinder is the formal n-point spherical function, but I encountered some trouble when pushing it to the eigenstate boundary value of the quantum spin Calogaro-Moser system related to the n-point spherical function."

"Do you have any good ideas?"

Qiu Chengtong smiled and looked at Xu Chuan. If there is anyone who can surpass him in mathematical research in today's mathematics world, this young man in front of him is definitely one of them.

Xu Chuan put down the manuscript in his hand, frowned slightly and began to think.

After thinking for a while, he shook his head and said, "This problem is difficult. I'm afraid it won't be solved in a short time."

"And to be honest, I'm not very deep in number theory. I don't know much in this field."

Indeed, his research in number theory is not very deep. Whether in the previous life or this life, I have basically not studied it in depth.

However, there are many famous conjectures in this area, such as the Riemann conjecture, the Goldbach conjecture, the twin prime conjecture, etc.

Qiu Chengtong thought for a while and then said: "If you rely on your intuition alone, where is the most likely way to solve this problem?"

"Intuition?"

Xu Chuan thought for a while and said: "Fundamentally speaking, the eigenstates of the quantum spin Calogaro-Moser system related to the n-point ball function are also the common eigenfunctions of the commutative family of first-order differential operators. Perhaps we can use the combination construction of equivariant differential entanglements related to the main series representation to make a breakthrough?"

"Of course, I don't study this deeply, I just say it casually, don't let me mess you up."

After listening to Xu Chuan's words, Qiu Chengtong adjusted his glasses and thought.

"Use a first-order differential operator to make an exchange? The combination construction of equivariant differential entanglements is used to make a breakthrough."

After thinking for a while, Qiu Chengtong's eyes were filled with a thoughtful light.

Then, he raised his head and said with some excitement: "No, this may really be a feasible way. The operator may give a new method by folding the classical dynamic r matrix and the related dynamic k matrix."

As he said, he quickly stood up and walked to the corner, dragged out a mobile blackboard from the corner, and began to deduce on it.
