In Shuimu University, Xu Chuan walked on the asphalt road shaded by green trees.
After finding Xu Xiao's phone number, I called her.
The bell rang for a while 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 by the way! 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 now and I can't leave, so just wait for a moment!"
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, perhaps 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 about it 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.
When 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 said welcome: "Hey, you are a rare visitor. What kind of wind brings you here?"
Xu Chuan smiled and said: "I came here for a meeting and came 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, 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. 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 teacup, 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, I can't say that I can fully understand the calculations and equations on the manuscript paper after reading them, but I can at least get a rough idea.
It has to be said that Qiu Chengtong is indeed a top expert who is hailed as the "Emperor of Mathematics" by Harvard University.
In his early seventies, he is still researching 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 heat core 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 Part II of the manuscript in your hand, I define and study a special subclass of global and formal elementary spherical functions, called global and formal n-point spherical functions."
"When the position variable goes to infinity, the limit of the correlation function of the Wess-Zumino-Witten conformal field theory on the cylinder is of the form n pointball function, which can be transformed into the quantum spin calogaro of the n pointball function correlation
-I had some trouble pushing forward the eigenstate boundary values of the -moser system."
"I wonder if you have any good ideas?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Qiu Chengtong looked at Xu Chuan with a smile. 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 the one.
One of the.
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, my research on number theory is not deep. I don't know much in this field."
Indeed, his research on number theory is not very in-depth. Whether in his previous life or this life, he has basically never studied it in depth.
However, there are many famous conjectures in this area, such as Riemann's conjecture, Goldbach's conjecture, twin prime conjecture, etc.
Qiu Chengtong thought for a moment and then said: "If you just rely on your intuition, which aspect is most likely to solve this problem?"
"Is it intuitive?"
Xu Chuan thought for a while and said: "Fundamentally speaking, the eigenstate of the quantum spin calogaro-moser system related to the n-point spherical function is also the common eigenfunction of the commutative family of first-order differential operators. Maybe it can
Make a cut with the combinatorial construction of equivariant differential entanglers associated with principal series representations?”
"Of course, I don't have deep research on this topic. I'm just talking about it casually. Don't let me lead you into confusion."
After listening to Xu Chuan's words, Qiu Chengtong adjusted his glasses and started thinking.
"Using first-order differential operators to make an exchange? The combinatorial construction of equivariant differential entanglers is used to cut in..."
After thinking for a while, Qiu Chengtong's eyes took on a thoughtful light.
Immediately, he raised his head and said with some excitement: "No, this may really be a feasible path. A new method may be given by explicitly folding the classical dynamic r matrix and the related dynamic k matrix by operators.
.”
With that said, he quickly stood up and walked to the corner, dragged out a mobile blackboard from the corner, and began to deduce on it.
