Great Country Academician

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

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

After the bell rang, it was connected.

"Brother! You actually called me?" Xu Xiao's surprised voice came from the other end of the phone.

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

"Of course! I'm your cutest sister!" Xu Xiaoli said confidently.

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

"Really?" Xu Xiao asked in surprise.

"Why are you lying to me? I have a meeting here in the capital for the past two days, so I just stopped by to see you." Xu Chuan said with a smile.

Xu Xiao: "Okay, so I did it by the way! Hmph!"

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

Xu Xiao: "Brother, can you wait for me to download, I am doing experiments in the laboratory now, if I can't leave, just wait and download!"

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

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

Xu Chuan smiled and said, "Okay, how long do we have to wait? If it's too long, I'll go shopping first."

"About half an hour to an hour, bro, take a stroll first, I'll call you when I'm done!"

Xu Chuan smiled and said, "All right."

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

This girl Xu Xiao actually entered the laboratory in her sophomore year. She guessed that her level might not be low, and she might be with her tutor, but at least it shows that she has made some progress academically.

But where would it be more appropriate to go shopping?

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

Mainly on the side of Shuimu University, he doesn't know any other familiar people.

Following the boulevard, Xu Chuan arrived at the 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 the desk and calculating something, raised his head.

When he saw the person who appeared at the door, he was stunned for a moment, then stood up with a smile, and welcomed him: "Hey, rare visitor. What wind brought you here?"

Xu Chuan smiled and said, "Come here for a meeting, and I'll come here to see my sister, but that girl is in the lab now, so I just wanted to come to your place."

Old Qiu smiled and said, "Welcome."

While talking, he got up to make tea: "Congratulations, you will be called Academician Xu in the future. The academician titles of the two academies were awarded in the same year, and you have broken another historical record."

Xu Chuan said with a smile: "I also didn't expect it. I thought I could only get an admission from the Academy of Sciences, but I didn't expect that the Academy of Engineering also applied."

Qiu Chengtong smiled and said, "You deserve it. Your contribution in the field of batteries and nuclear energy is enough."

After exchanging pleasantries for a while, Qiu Chengtong took a sip of tea, smiled and said, "It's better to come by chance than to come here. It just so happens that I've been researching a problem for the past two days and I've encountered some troubles. Can you help me?"

Hearing this, Xu Chuan asked curiously, "Oh? What aspect?"

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

Xu Chuan took the manuscript paper and flipped through it. The formulas and equations on the manuscript paper gave him a hint of interest in his eyes.

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

With his mathematical ability, he can't say that he can fully understand these formulas and equations on the manuscript paper, but at least he can understand them roughly.

It has to be said that Qiu Chengtong really deserves to be called the "Emperor of Mathematics" by Harvard University.

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

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

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

To put it simply, the KZB equation is somewhat similar to the NS equation. Both of them gain more related things when studying this equation.

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

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

Xu Chuan gave a thumbs up, this β outfit is for him!

Very mellow.

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

"When I was researching this, I once saw the paper on the proof 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."

"As the position variable tends to infinity, the limit of the correlation function of the bounded Wess-Zumino-Witten conformal field theory on a cylinder is a function of the form n-point spherical, which can be expressed in the quantum spin calogaro related to the n-point spherical function - I'm having some trouble pushing the eigenstate boundary values ​​of the moser system."

"I wonder if you have any good ideas?"

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

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

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

"And to be honest, I don't have a deep study of number theory. In this field, I don't know a lot."

Indeed, in the area of ​​number theory, his research is indeed not very deep. Whether in the previous life or in this life, basically I haven't studied deeply.

However, there are many famous conjectures in this area, such as Riemann conjecture, Goldbach conjecture, twin prime conjecture and so on.

Qiu Chengtong thought for a while, and then said: "If you rely only on your intuition, which aspect is the most likely 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 spherical function are also the common eigenfunctions of the commutative family of the first-order differential operator. Make a cut with the combinatorial construction of equivariant differential entanglements associated with principal series representations?"

"Of course, I don't have a deep research on this area, so just say it casually, don't be confused by me."

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

"Use the first-order differential operator to make an exchange? The combinatorial construction of the equivariant differential entangler cuts in."

After thinking for a while, Qiu Chengtong had a thoughtful look in his eyes.

Immediately, he raised his head and said with some excitement: "No, this may really be a feasible path, and the folded classic dynamic r matrix and the related dynamic k matrix explicit by the operator may give a new method .”

As he spoke, he quickly got up and walked to the corner, dragged out a mobile blackboard from the corner, and began to reason on it.
