April 30, the last working day and study day before the May Day holiday.

"Shen Qi, you have participated in the Golden Autumn Camp of Yan University, you are no stranger to Yan University, you can play by yourself, I will go to Shijingshan to find my girlfriends and old classmates to get together. Something to call the Union. After Mu Rong finished speaking, she ran away alone.

"Publicly-funded business trips, private blind waves...... You, then you go to the waves. Looking at the back of Teacher Mu in the distance, Shen Qi was relaxed.

In just a few days, it was impossible for Mu Rong to teach Shen Qi too many things, so it was better to go into battle lightly.

Coming to Yan University again, Shen Qi is indeed no stranger, he was alone on the campus of Yan University, and called Professor Sun Erxiong of the Department of Mathematics as soon as possible. When I came to Yanda, I didn't say hello to Professor Sun, I was not sensible.

"Professor Sun, I'm Shen Qi back again!" Shen Qi said excitedly on the phone.

"It's great to be back?" Sun Erxiong sounded very noisy.

"This ......" Shen Qi was speechless, yes, this is Yan Da, forcing Wang to walk all over the street, what's the big deal about me coming to the pre-enrollment of a mathematics department?

"I'm too busy to pay attention to you right now, and you'll be listening to a speech in the auditorium an hour later. Sun Erxiong hung up after speaking.

"This ...... Old Sun, you have changed. "Shen Qixin said that last autumn, Lao Sun, you invited me to eat dumplings, eat steamed buns, and give me directional suggestions, which was good to me, but this year's May Day, why did you become like this?

He Fangsheng gave a speech in the auditorium today, so that Lao Sun did not have time to talk to me? Shen Qi walked towards the auditorium.

Walking to the auditorium, Shen Qi saw a big sign erected at the entrance of the auditorium, with words on it: "Welcome internationally renowned mathematicians Yun Wei and Gong Changwei to return to the school to give speeches." ”

"It turned out that Yunshen and Weishen were back, no wonder Lao Sun didn't have time to take care of me!" Shen Qi was still a little complaining about Sun Erxiong just now, but now, he was relieved.

Who are the great gods of the clouds and the great gods?

They are the pride of the Department of Mathematics at Yan University, and the most promising Chinese mathematicians of our time to challenge for the Fields Medal.

F+W+A mathematics super slam winners such as Jean-Pierre Serre, Deligne, John Mirno, and John Thompson are too far away from Shen Qi, and he doesn't know if he can see these living super-bulls in the mathematical world in his life.

(F = Fields Medal, W = Wolf Medal, A = Abel Medal)

The slightly younger F+W+A Grand Slam winner, Shen Qi has a fate, that is, Andrew Wiles.

Even though he had a relationship with Andrew Wyles in London, Shen Qi moved Sir Wyles too far away from him.

Yun Wei and Gong Changwei are different, they are both Chinese, very young, in their thirties, both are produced by the Department of Mathematics of Yan University, and both of them won IMO gold medals when they were in middle school...... This makes Shen Qi feel very immersed.

Entering the auditorium to find a seat and sit down, Shen Qi looked around, and there was nearly an hour to speak, and a small half of the audience had already come to the auditorium, all of whom looked like college students.

So Lao Sun was busy entertaining Yun Shen and Wei Shen, right? Shen Qi figured it out and sat back and waited for the speech to begin.

It is not ordinary people who can give speeches in the auditorium of Peking University, Clinton has given speeches here, Chirac has given speeches here, Gates has given speeches here, as well as many scientific experts and well-known young scholars.

At three o'clock in the afternoon, the auditorium was full and the speech began.

The host solemnly introduced: "Yun Wei, winner of the Science Breakthrough Prize, Ramanujan Prize, and the youngest professor at Yale University, is invited to give a speech!"

Bang Bang Bang!

There was warm applause from the audience, and Shen Qi was also applauding, cheering for Yunshen from the bottom of his heart.

The host highly summarized Yunwei's achievements in three sentences.

The Breakthrough Prize was founded by business tycoons such as Zuckerberg, Jack Ma, and Sejiblin, and several bigwigs own companies such as Facebook, Alibaba, and Google that rely on technology to eat.

The Breakthrough Prize is awarded in life sciences, basic physics, mathematics and other categories, with a single prize of up to $3 million, far exceeding the Nobel Prize.

The Ramanujan Award, which is known to those who are engaged in mathematics, is second only to F+W+A in the world.

Yun Wei, who is in his early Chinese New Year's Eve, is a professor in the Department of Mathematics at Yale University, the youngest full professor in Yale's centuries-old history.

Yun Wei was wearing glasses, and he looked like a gentleman, and he said, "I'm stupid, so I chose mathematics." ”

Hehe.

The audience let out a knowing laugh, why are you stupid? Then we are all mentally retarded.

Yun Wei briefly introduced his experience, he loved mathematics since he was a child, and won the IMO gold medal in his sophomore year of high school (he was a gold medal with a perfect score), and then he was very lucky to be sent to the Department of Mathematics of Yan University......

All the way to this point, Shen Qi listened very emotionally, my experience is very similar to Yunshen...... Well, the last year or two.

Yun Wei said a few words lightly, when I was an undergraduate in the Department of Mathematics of Yan University, I won the title of three good students every year, and the mathematics major exam was basically full scores, and the only thing I missed was number theory, and I was particularly afraid of number theory.

"So I didn't dare to touch number theory, and when I was studying for a master's degree or a doctorate in the Department of Mathematics at Princeton, I chose the direction of algebraic geometry......"

After completing his undergraduate studies in the Department of Mathematics at Yan University, Yunwei went to Princeton to study for a Ph.D., then worked as a lecturer at MIT, an associate professor at Stanford, and is now a professor in the Department of Mathematics at Yale University.

"The field I am studying now is called the Langlands program, which can be understood as a new program of number theory + algebraic geometry, which has historical significance, and I hope to make a breakthrough and let the name of Chinese mathematicians shine on the world stage. ”

Bang Bang Bang!

The audience interrupted Yun Wei's speech with thunderous applause, and most of the audience were teachers and students of Yan University, who knew how to do it.

"Amazing, Yunshen, if you get the Langlands program, the Fields Medal or something is trivial, this program is enough to dominate the international mathematical martial arts." Shen Qi applauded warmly, of course he knew the significance of the Langlands program.

The fields of study known as "program" in the mathematical community are particularly impressive.

So far, there have only been three programs in mathematics: the Irrigan Program, the Hilbert Program, and the Langlands Program.

The first two programs emerged in the 19th and early 20th centuries and led the development of mathematics for nearly a century.

The Langlands Program was proposed in the mid-to-late 20th century, and in layman's terms, the Langlands Program is that it integrates number theory, algebraic geometry, and group theory to form a programmatic guiding document.

In layman's terms, if a mathematician can't solve a problem in one area, he solves it in another.

There is no mathematical problem that cannot be solved by the Langlands Program, and if there is, do it again...... Theoretically, if the Langlands Program is thoroughly proven, it will have the programmatic power of this universal nature.

After the 90s, three mathematicians partially solved some conjectures in the Langlands program and won the Fields Medal, one of which was the contemporary mathematics giant Drinfeld.

In fact, F+W+A Grand Slam winner Andrew Wiles proved Fermat's theorem, which provided very important support for the Langlands program.

Wiles is a master of number theory, he is very sensitive to numbers, do you think that as an Englishman, it is easy to quickly mentally calculate addition, subtraction, multiplication and division within 40? No, this requires a very high talent in arithmetic, and Wiles has this talent, so he won the Fields Medal and became one of the great bulls in mathematics today.

The presence of such a program is very attractive. Shen Qi set a lofty goal in his heart, the Langlands Program, I hope that before Yunshen you get it, I can also get involved in one or two.

"I am very honored to be able to return to my alma mater this time, and I would like to thank my teachers in the Department of Mathematics of Yan University, Mr. Zhang Yuxin, Mr. Su Weilong, and Mr. Sun Erxiong.

The first two teachers, Mr. Zhang and Mr. Su, are both famous teachers in the Department of Mathematics of Yan University, and Sun Erxiong is not as famous as them, but after all, he has taught mathematics at the undergraduate level of Yunshen.

"Fat old Sun, you are also a famous teacher?" Shen Qi looked left and right, Professor Sun must be in this auditorium, more than 200 catties is such an obvious goal, what about people, where are you sitting?
