This is just a small episode in the preparation work. Lu Qiujian was preparing his speech and logging onto the arxiv website to publish a paper and browse the latest articles on the Poincaré conjecture. In addition to learning cutting-edge physics knowledge, he also had one more thing to do with the colleagues convened by the Capital University.

The audio translators work together to prepare the translation manuscript.

As time went by, the venue for the report meeting was prepared, the translation of the speech was verified to be correct, the training of conference volunteers was successfully completed, and the list of invited leaders was finalized; and most importantly, the leaders who were invited to participate in the meeting were

The mathematicians started their own journey. They came out from New York, Los Angeles, London, Humboldt, Moscow, Tokyo, Paris, the Pearl, and the gates of various world-renowned university institutes, and rushed to the nearest airport to the capital of China.

fly away

Volunteers from the logistics staff of Beijing Normal University also took action, making preparations at the airport, train station and at the school gate to welcome the arrival of these mathematics masters.

The Mathematics Department simply suspended classes for a week and gathered the students to arrange various key points to cooperate with the school's work; Lu Qiujian's roommates Xu Ye and Li Yincheng were sent to the hotel entrance to do reception work.

"I'm sitting comfortably in the hotel with the air conditioner blowing and drinking tea, and we're just waiting hard under the sun to prepare for the reception." Xu Ye looked at the top of the hotel with envy. In order to better communicate with these mathematics students, the school

We communicated with each other and arranged for Lu Qiujian to be here as well.

"Who asked someone to make achievements? Besides, it's not useless for us to stay here. If we get in touch with that master, it will be convenient to apply to study abroad." Li Yincheng looked more far-reaching, "If we can meet him later,

Just go to Professor Atiyah in Cambridge, chat with him and ask for an email address, maybe I will be taken to the UK by him."

"You still understand, I mean, how can I talk to these people? The job is either assigned to seniors or to third-year graduate students. It turns out that the school has already planned it." Xu Ye suddenly realized, and only then did he realize that this was a job given by the school.

An opportunity, "Then I'm going to say hello to Professor Jean-Pierre Serre from the Collège de France."

"Who are you talking about?" the girl borrowed from the School of Foreign Languages ​​asked curiously. There was no way, there were too few girls in the mathematics department, and it was shameful that there were not two good-looking girls at the reception desk. So I had to go from there.

I went to the foreign language department where there are many beauties.

"Xiaoyue, what we just talked about is the authority of mathematicians." It was a rare opportunity to talk to the girl again. Xu Ye quickly began to answer her questions, "Michael Francis Atiyah is the dean of Trinity College, Cambridge. He majored in topology.

He has made outstanding contributions to the field of k-theory Lie group representation and algebraic geometry related to gauge fields.

He won the Fields Medal in 1966. Jean-Pierre Serre is a professor at the Collège de France. His main contributions are topology, algebraic geometry and number theory. He was the winner of the Fields Medal in 1954. Oh, by the way, Fields.

The Prize is the highest award in our mathematics community. It is equivalent to the Nobel Prize in physical chemistry and medicine."

"Oh~ I seem to understand that they are all top figures in the industry." The girl known as Xiaoyue asked again, "Then they came to Capital University just to attend this lecture by Lu Qiujian?"

"Yes, Qiu Jian solved the Poincaré conjecture among the seven major mathematical problems, so these people are here." Xu Ye's tone revealed endless envy. It would be great if he was the one who made the results.

"I heard that he is only 20 this year? He is so good at basketball that he almost went to the NBA?" The little girl asked a series of questions, and Xu Ye was very heartbroken with stars in his eyes.

Fortunately, his depression did not last long. Li Yincheng quickly patted his shoulder and said, "Stand still. I just called and said the car will be here soon."

Xu Ye quickly turned around and stood up, muttering quietly, "I wonder who is here this time?"

While talking, Professor Zhang and others also came down and waited at the door for five minutes. The car stopped at the door of the hotel. A man about fifty years old got out of the car. Professor Zhang and Lu Qiujian hurriedly greeted him, "

Professor Friedman, hello, welcome to China”

While they were chatting, Xu Ye and Li Yincheng quickly went up to help Friedman unload their luggage, and followed them to the hotel.

"Wow, that's Lu Qiujian, I'm afraid he's over 1.85 meters tall." After returning to the door, Xiaoyue sighed and asked, "Who was that just now?"

"Academician of the National Academy of Sciences and Professor Michelle Friedman of the University of California. Winner in 1986." Xu also directly omitted the name of the Fields Medal this time.

Then they welcomed Cheng-Tong Yau from Pearl Chinese University, neon mathematician Kiyoshi Ito from the University of Minnesota, Chio Sato from Kyoto University, Arnold from the University of Paris, Harry Furstenberg from the Hebrew University of Jerusalem, and Yu from ETH Zurich.

The value of Ergen Moser, a great mathematician, dazzled their eyes, and even Xiao Yue, who didn't know much about mathematics, became excited.

At five o'clock in the afternoon, the most exciting moment finally arrived; a bus slowly stopped at the door, and the door opened. Pierre-Rene Deligne, who was nearly sixty years old and had half his hair bald, said respectfully

He helped an old man who was older than him slowly step out of the car.

"Oh my god, why are he here?" Xu Ye and Li Yincheng's eyes widened immediately, and their whole bodies were shaking with excitement. They could hardly help themselves, and they finally hurried up to help them carry their luggage upstairs.

"Is this person great? Why didn't I see you so excited just now?" In her opinion, there didn't seem to be anything special about the person just now except that he was older.

"That's Grothendieck. I didn't expect that he would come out after retiring for so long." Even though Xu Ye hadn't fully recovered yet, he waved his arms excitedly and said, "Let me tell you this, in the entire history of mathematics, ancient

Among Greek mathematicians, Euclid, Archimedes and Diophantus had the greatest influence; in the first half of the 17th century, Descartes and Fermat were the most influential, and in the second half of the 17th century, Newton and Lydia were the most influential.

Leibniz is juxtaposed. From the perspective of subsequent historical development, Leibniz had a greater impact on mathematics, but Newton had a greater impact on physics; Euler in the first half of the 18th century, Gauss from the end of the 18th century to the first half of the 19th century, and Gauss in the 19th century.

In the second half, Riemann and Poincaré were tied. The first half of the 20th century belonged to Hilbert, and the second half belonged to Alexander Grothendieck." To be continued.
