"Knock knock!"

"Come in, the door is unlocked!" A neutral voice came from inside the door.

Junxin pushed the door in, only to see that the office was spotlessly cleaned, and a middle-aged man in his thirties sat on the desk in the middle, and he said without raising his head, "Wait a minute, let me finish thinking about this problem, there is tea and drinks next to it, you can solve it yourself." ”

This is said very smoothly, as if it has been rehearsed hundreds of times, and it is completely when someone comes in, subconsciously saying it, and even the person who speaks may not notice the meaning of the words.

Jun Xin didn't speak, and followed Professor Faltins' words softly to the side of the sofa, where the table was indeed full of all kinds of drinks, as Professor Faltins had said.

Junxin, who is accustomed to Chinese eating habits, naturally chose tea as his drink. Unceremoniously brewed a pot of black tea, poured himself a cup, and tasted it beautifully.

You must know that the black tea in the Institute for Advanced Study is almost all made of high-grade tea, which can be said to be priceless, and it is the kind that ordinary people can't easily drink. Junxin naturally had the intention of tasting it well, and took advantage of Faltins to have a good taste when he was thinking and solving problems.

I don't know how long it was, but Professor Faltings suddenly said, "William, is there anything to find me today?" ”

When Junxin looked up, he saw that Professor Faltings seemed to have thought about it, but he still didn't look up at Junxin, he thought he was someone else. However, when he heard the name William, Junxin's heart moved, and he seemed to think of something.

"Hello, Professor, I'm not Professor William Thurston!" Jun Xin said with a smile.

"Oh? Isn't it William? So which Thurston are you? Faltins raised his head, a hint of confusion flashing in his eyes, obviously thinking that he had not yet departed from what he had just thought.

Junxin didn't speak, just smiled and looked at Professor Faltins, who was gradually returning to normal. For a long time, the confusion in Professor Faltins' eyes faded away, and a glimmer of wisdom flashed instead. I saw Professor Faltings frown slightly, and asked with a hint of seriousness, "Who are you?" Is there anything looking for me? ”

"Hello, Professor!" Junxin put down the teacup in his hand, stood up, walked over to Professor Faltins, and said, "My name is Junxin, and I'm from China. He is currently a sophomore in the Department of Mathematics at Princeton University. ”

"Junxin? A familiar name. Faltins muttered to himself, "Wait, Junxin? Are you the Chinese mathematician that Moder guessed? ”

"Mathematicians don't dare to be a mathematician, and I'm the mathematics student at China's Shuimu University that Modell guessed." Junxin said very calmly, after the self-reflection and torture just now, Junxin's whole person has a kind of heartfelt calm, so even if he sees Faltins, the person who solved Moder's conjecture in the original world, Junxin can face it very calmly.

"Hello, hello!" Faltins happily stretched out his hands to Junxin. Jun Xin was naturally not pretentious, and shook Professor Faltins's hands.

"I heard in China that the manuscript of my paper was reviewed by the professor, and some of the comments you gave during this period were very valuable, so I just arrived at Princeton University yesterday, and I came to visit you today, and by the way, I would like to thank you and ask for advice."

"It's a trivial matter, and even without me, the other editors would have let the paper pass in the same way!" Faltins said nonchalantly, "I'm just giving some specific explanations on the solution to the problem that Titt guesses, so you're welcome." Come on, come on, sit down and say. ”

"Thank you, Professor!" Junxin nodded, and walked to the couch with Faltins. Faltins chose a cup of coffee, and Junxin continued to refill a cup of black tea.

"By the way, I would like to thank you for your support from behind, if it weren't for the invitation from you and the professors, I'm afraid I wouldn't have been able to get this exchange student place." Junxin said gratefully.

"Oh? Why? At your level, even if you go to any university or research institute in the world, you can become a professor, why is it so difficult to even get an exchange place? ”

"It's not what you thought it would be!" Jun Xin glanced apologetically, "The Department of Mathematics of our Mizuki University was just re-established last year, although there have been Professor Chern Shiingshen and Professor Hua Luogeng and other figures before, but after a period of time because of some adjustments in the country's scientific research projects, so the Department of Mathematics of Mizuki University was adjusted to other schools, and it was just re-established the year before last, and it is not so authoritative, if it were not for the invitation of you and several other professors, I am afraid that I would not have had the opportunity to get this exchange opportunity." ”

"Looks like we're doing the right thing!" Faltins said with a smile.

"Haha..."Junxin and Professor Faltins gossiped with each other for a while, and then the topic changed and entered the mode of academic exchange.

However, in most cases, it was Professor Faltings who was asking, and Junxin was answering, and the two exchanged questions about some details of Modell's conjecture. Regarding the Modell conjecture, Faltins has only just begun to study this problem, and has not gone too deep, although he has read Junxin's paper and understood Junxin's thinking, but he thinks that this kind of problem will naturally be more fruitful if the person himself says it, so the questions asked are very detailed.

After a year of top-notch study and research, Junxin has begun to develop its own research style and begin to form its own way of thinking. And with the accumulation of mathematics in the next few decades, although many problems have never been encountered or thought about by themselves, Junxin can always give an answer or a direction through a little thinking.

Gradually, the discussion between the two was not limited to the Model conjecture, but entered a deeper discussion of algebraic geometry. As the level of communication of issues becomes more and more in-depth, there will naturally be more and more arguments, so it is inevitable that the voices will become louder and louder. This caused Professor Faltings' teaching assistant to open the door more than once, lest the two get into a fight over academic issues.

However, although the argument between Junxin and Professor Faltings was fierce, it also inspired the two of them, and they also had some clues and ideas for some questions that were difficult to answer before, which can be said to be a huge gain.

"Jun, I'm sure you're a genius indeed!" Faltins and Junxin communicated very happily, and he even had a hearty feeling, although since Riemann, algebraic geometry began to gradually rise, and even to the limit in the hands of Grothendieck, but there are not many really top masters of algebraic geometry, and most of them are nested in France. Although Princeton is the center of mathematics, algebraic geometry is not the strongest branch, so there is no one who can have such a fierce confrontation with Faltins in the field of algebraic geometry, and today's Junxin makes him feel the pleasure that he has not felt for a long time.

"Thank you for the compliment, some of your opinions have inspired me a lot, I think that the Modell conjecture may be further studied, and I may already have a little idea!"

"That couldn't be better!" Faltins said with a laugh.

"Oh, yes! You've come just in time! Some time ago, President William approached us and asked us to come forward and invite you to give a lecture on Modell's conjecture, what do you think? ”

"I'll follow the school's arrangement, but at least wait until I start school!" Junxin did not refuse.

"Just say yes, the assistant principal will come to you in a few days to talk about the lecture on Modell's conjecture, just prepare yourself!" After a pause, Professor Faltings added, "But I think that with your level, it doesn't matter if you don't have to do any preparation, it's enough for any situation!" ”

"Thank you!"
