There was nothing to say all the way, Junxin was immersed in his own mathematical world, and the two men sitting there were both scholars, seeing this scene, they naturally knew that Junxin was doing research, so they lowered their voices when they talked or something. And the daughter and family members of the educated youth also watched quietly and did not make any sound.

I don't know how long it took for Junxin to be woken up by the teacher, it turned out that Hefei had arrived unconsciously. Junxin hurriedly packed his luggage and got off the bus with the flow of passengers.

In the 80s, train stations were generally chaotic and busy, and even 30 years later, the situation is not much better. However, before Junxin came to Hefei this time, Professor Wang had already called him and told him that his treatment would be distributed according to the associate professor of the University of Science and Technology of China. According to this treatment, Junxin doesn't need to bring anything, so a simple backpack with a few clothes and some daily necessities in it has no other supplies. I brought a few textbooks from IHES that came from Professor Hu's side. It's just that there are more French, so Junxin only chose a few English textbooks.

As soon as he walked out of the train station, Junxin glanced around and saw a more eye-catching place next to the platform, holding a sign with his name written on it. Jun Xin couldn't help but feel warm in his heart, knowing that this must be Professor Wang's arrangement. After greeting a few people in the same seat, Junxin walked over there.

The two people sitting there, a man and a woman, were probably about twenty-four or five years old, and if they were not mistaken, they should be graduate students led by Professor Wang. Junxin is concerned about the girl, in his impression, there should be very few girls who choose to study mathematics, sometimes it is normal for all the students in a mathematics department to be boys, for example, their mathematics department in Mizuki, there is no girl for two consecutive years.

"Hello, I'm Junxin!" Junxin placed the bag on the ground and stretched out his right hand.

"You... You are? The two of them looked at Junxin, a little overwhelmed. Before coming, Professor Wang only told them to pick up a person named Junxin, but he didn't explain in detail what kind of person Junxin was. They didn't expect Junxin to be so young, so that when Junxin stepped forward to say hello, they were a little confused.

"If I'm not mistaken, Professor Wang Yuan asked you to come, right? I'm the Junxin from Beijing Shuimu University! "Junxin didn't care about the expressions and attitudes of the two, there are more such things." Are we standing here? ”

"Oh, okay, okay," the boy shook Junxin's hand and said, "The professor said he has some things to deal with, let's take you to his office first." ”

"Let's go!" Junxin smiled and motioned to the two of them.

"Are you really Mr. Junxin?" Walking silently behind the two, the girl suddenly turned around and asked.

"What? Too young? Not like? Jun Xin tilted his head and asked.

"No, I just think ......" what she thinks, she didn't say.

Jun Xin smiled, he naturally knew what the so-called feeling in the girl's mouth meant, "I think I should be an adult person, right?" But in fact, I am only a freshman, and now I am only 17 years old, so I am naturally younger. ”

"But you're too young, aren't you?" The boy threw Junxin's bag in the trunk of the car, and said with an amazed face, "I have been under Professor Wang for two years, and most of the people who are valued by Professor Wang are twenty or thirty years old. She and I were also lucky to get Professor Wang's favor, you are still so young, Professor Wang actually values you so much, it's really..."

Junxin suddenly felt a little crying and laughing, it seems that they didn't think of the meaning of the name Junxin in the current mathematical world. It seems that after solving the Modle conjecture, Junxin fell silent after a burst of media publicity. So the impact wasn't that big.

But the two people who took him were also considered people in the mathematical world, and they didn't think of their own results according to their own names. This made Junxin cry and laugh at the same time, and at the same time, he also became a little interested in these two people.

In the study of mathematics, the content of university mathematics is very similar to that of all mathematics departments in the country. However, when mathematics reaches the graduate level, like any other discipline, it is necessary to study in different directions. If you are not familiar with yourself, then you will definitely not be a person in the area of number theory and analytic number theory. So when they see the article, they can scan it at most. After all, since mathematics entered the modern era, it was almost impossible to find an all-round person, and at this point, Grotendieck counted half.

"What is the direction of the two senior sisters and brothers?" Junxin asked curiously.

"I study geometry, and the main research object at present is Riemannian geometry, but the research is only about those contents, and there is nothing new." The senior brother asked Junxin to sit in the back of the car, and then got into the front passenger himself, while explaining that the car was a car from the school sent by Professor Wang.

"Riemannian geometry!" When he first studied general relativity in physics, the teacher who taught this subject once said that when Einstein established the general theory of relativity, he used Riemannian geometry (strictly Lorentz geometry) and tensor analysis tools.

In addition, in 1944, Professor Chern gave the proof of the connotation of the Gauss-Bonet formula of the n-Villemannian manifold, and his research on the demonstrative class of Hermitian manifolds, which was later commonly known as the demonstrative class, which provided an indispensable tool for large-scale differential geometry and created a precedent for the study of differential geometry and topology of complex manifolds. This is also the reason why he is known as a master of differential geometry.

"Where's Senior Sister?" Jun Xin suppressed the surging thoughts and asked.

Senior sister smiled and said with a smile: "I am not an outlier under Professor Wang like him, I have the same research direction as the teacher, and we are both in analytic number theory. ”

"What kind of outlier am I, isn't that guy Zhou Jianhai more alternative? I studied Riemannian geometry because I was very interested in complex functions when I was in college, and even if I study Riemannian geometry now, because the relationship between the two is relatively close, it doesn't change much. But when that guy was in college, he mainly studied ordinary differential equations, but now he has directly abandoned ordinary differential equations and turned to mathematical logic, which is almost completely out of line with the previous ones. ”

A trace of curiosity suddenly flashed in Junxin's eyes, which reminded him of his book "Principles of Mathematics", Russell's Principles of Mathematics is more of a work on mathematical logic, and Mizuki University has no such course because of its application characteristics, and Junxin cannot find anyone who can exchange knowledge in this area. Now that he met a graduate student in mathematical logic, Junxin suddenly felt that this trip was worth it, and he began to look forward to studying life scenes with the students of HKUST for more than a month.
