From top stream to scholar

The little old man trembled, but there was light in his eyes.Yu Wanzhou froze for a moment, Academician Jess bowed slightly and said, "Your Majesty Grothendieck."

"Oh?" He said slightly, "Is there anything you want?"

"Your Majesty Grothendieck." Academician Jess paused, "I know you don't want to see me, but today it's not me who wants to see you, but Mr. Yu who wants to see you."

"Yu?" The little old man looked at Yu Wanzhou with his eyes, "Yu-wan-zhou?"

The jerky Chinese could not tell whether Yu Wanzhou's name was being said, Yu Wanzhou nodded slightly, and said in fluent English, "Hi Mr. Grothendieck, I am Yu Wanzhou."

The little old man opened the door and said to Yu Wanzhou, "Come in."

But he paused again, and said to Academician Jess, "Just stay outside, and Yu can come in alone."

"..." Although I know that Mr. Grothendieck does not welcome him, there is no need to let him not go in so directly. Beating people is not a slap in the face, so just keep beating him in the face, right? ?But after all, this is the God of Mathematics, so he can only wait outside the door.

When Yu Wanzhou entered the courtyard, the flowers were very bright, and the fragrance of the flowers that hit his face made him very intoxicated.

"Go in." The little old man led Yu Wanzhou to the house, and when he entered the house, the inside was not magnificent, but quite old.Yu Wanzhou was a little surprised.

"Coffee?" Grothendieck said coldly to Yu Wanzhou.

"Thank you, sir." Yu Wanzhou nodded. It doesn't matter what he drinks, the important thing is that he wants to communicate with this math god.It must be very beneficial to his academics. After sitting down, he poured a cup of coffee and placed it in front of Yu Wanzhou.

"I have read many of your papers, and I must admit that you are a very good and talented mathematician." He paused, stirred the coffee with a spoon, and then took a sip.Putting down the coffee cup, he continued to say to Yu Wanzhou, "Obviously, you have extraordinary talents in algebra and geometry."

"Next, what are your plans?"

"Yang-Mills Existence and Quality Gap, perhaps followed by the verification of the Langlands program."

"Very good, you seem to be very interested in the grand unified theory of mathematics." Grothendieck changed a relaxed posture and said to Yu Wanzhou, "As people get old, their thinking has degenerated."

"But it is irrefutable that you are still the Pope of Mathematics, and I will call you the Pope of Void in private."

"Oh?"

"Because a biography about you seems to come from the void." Yu Wanzhou said with a smile, "I want to ask you some questions about algebra and geometry."

Yu Wanzhou and Grothendieck chatted very well, but academician Jess standing outside the door was miserable.

He stood outside the door and waited for a long time, but Yu Wanzhou didn't come out.The laughter from inside the house meant that Yu Wanzhou and Grothendieck had a very pleasant chat.

Leaning against the wall, Academician Jess sighed slightly.He couldn't even get into Grothendieck's house. This Mr. Yu's first visit, Grothendieck chatted so happily with him.Sure enough, this boss is only interested in geniuses.A genius like Yu Wanzhou can really arouse the interest of this mathematics god, as for himself.He and the old academician came many times, but each time he was refused to enter the home of the God of Mathematics. Simply put, since he worked at the Paris Academy of Sciences, although he will come here to see Mr. Grothendieck once at a fixed time , but is still prohibited from entering.

In the end, the sky gradually darkened, and Yu Wanzhou hadn't come out of the house yet, but she heard a lot of chattering voices.For example, geometry, algebra, etc., because the two of them chatted so deeply that he didn't even understand it, and it was still vague.

He tugged on his tie, and simply sat on the floor regardless of his image. He didn't expect the two of them to chat from daytime to evening. Judging by the situation, they might not be staying here today.

Sure enough, after a while, Grothendieck and Yu Wanzhou came out together.

After shaking hands with Yu Wanzhou, Grothendieck smiled at Yu Wanzhou and said, "Yu, I hope to see you tomorrow."

"Don't worry, I will definitely come to visit you, the Pope, tomorrow." "There are still many questions I want to know with you." Yu Wanzhou smiled, and after Grothendieck opened the door, Yu Wanzhou left .Looking at Academician Jess who just stood up, Grothendieck's eyes turned cold again, "Yu, I think it's fine to see only you tomorrow."

"Okay." Yu Wanzhou nodded slightly, "I assure you, you will definitely only see me tomorrow."

I talked with Grothendieck almost all day about academic issues, and he had a lot of new inspirations in geometry and algebra.As expected, he is indeed the God of Mathematics. Talking to him about the academic world is almost as good as spending several years studying in the house.

"Excuse me, Academician Jess." Yu Wanzhou said apologetically, "I didn't expect that Mr. Pope would not let you in."

Jess said dumbfoundedly, "I'm used to it, this gentleman has always had a weird temper."

"If it weren't for Mr. Yu, you are really talented in mathematics, I am afraid that this gentleman would not want to see you." Academician Jess paused, "But Mr. Yu, when will you be able to go to the Paris Academy of Sciences?"

"After talking with the Pope, I will go to the Paris Academy of Sciences. It won't be too long." Yu Wanzhou paused, "It may be a few days, Academician Jess, please leave me a contact The address. How would you like me to call you when I arrive in Paris?"

"Okay." Jess and Yu Wanzhou exchanged addresses, and finally Yu Wanzhou stayed in a small hotel at the foot of the Pyrenees.

Yu Wanzhou benefited a lot from going to Grothendieck's home every day to discuss academic issues with him.This great god is worthy of being known as the Pope of Mathematics. His profound thoughts seem to come from the wisdom of the void. Yu Wanzhou couldn't help but get goosebumps all over his body.

Until the last day, Yu Wanzhou was about to leave.

Grothendieck said to Yu Wanzhou, "Yu, what are you going to do next?"

"Probably go to the Paris Academy of Sciences to give some lectures on the theory of automorphic functions." Yu Wanzhou thought for a while, "Maybe I will also go to England to visit Mr. Wiles and Sir Atiyah."

"Then I may return to my homeland, Huaguo." Yu Wanzhou paused, "Sir, do you have any other instructions and teachings?"

"No." Grothendieck shook his head slightly and said, "Yu, I didn't expect that I would have many different ideas when communicating with you."

"However, I am afraid that the academic essence of my life has been learned by you."

Yu Wanzhou froze for a moment, and he only stayed here for more than ten days, learning the academic essence of the Pope, it is impossible.That is a vast wisdom, how could it be possible to learn all of it in more than ten days? Yu Wanzhou is already very satisfied if he can have one-thousandth of it.

Grothendieck smiled and said nothing, "You are the person who surprised me the most. Your talent in mathematics is unparalleled."

"Thank you for your affirmation of me." Yu Wanzhou breathed a sigh of relief, Grothendieck thought about it, and then said to Yu Wanzhou, "Yu, I am very optimistic about your future."

"Thank you." After saying goodbye to Grothendieck, Yu Wanzhou thought for a while, and it was really from Grothendieck that he learned a lot of algebraic and geometric method arguments and a lot of profound ideas that he hadn't been exposed to before.Some of these are circulated among various mathematicians, but they are all Grothendieck's residual manuscripts.All the real manuscripts were destroyed or taken away by Grothendieck.

These days when Yu Wanzhou talked with Grothendieck, he obviously felt that he was exposed to geometric and algebraic ideas that he had not been exposed to before.The feeling of suddenly realizing is like seeing the sun through the clouds in a fog.

Have fun!

But Grothendieck said that he had learned all the academic essence of this gentleman, and Yu Wanzhou felt that this was unlikely.Probably the Pope is praising himself.It would be much better to take this sentence as a compliment to yourself.When leaving, he happened to meet Professor Deligne.

Both Yu Wanzhou and Professor Deligne were taken aback for a moment.

"Yu, are you here as a professor?"

When Professor Deligne was a doctoral student, the professor was Mr. Grothendieck. It is not surprising that he came here, but this professor is still quite far from the United States to France.

"Professor Deligne." Yu Wanzhou shook hands with Deligne. "I just finished chatting with Mr. Pope. Mr. is a very funny and profoundly wise man, and he is very admirable."

Deligne smiled, "It seems that you and the professor had a very pleasant chat."

"It should be more pleasant." Yu Wanzhou said, "I'm about to rush to the Paris Academy of Sciences."

"I also came back for this matter. Congratulations, Yu, you have won the Poincaré Gold Medal." Deligne congratulated Yu Wanzhou, "Then what is the lecture you are going to do?"

"The theory of automorphic functions, if Professor Deligne is interested, I would like to invite Professor Deligne to listen to it. I thought of a wonderful way to promote the theory of automorphic functions in algebra and geometry."

"Ah?" Deligne was stunned for a moment. He himself is a top master in the field of algebra and geometry, so he was naturally interested when he heard this thing.

"It seems that I have to go and listen."

"Welcome!" Yu Wanzhou smiled, "Then I will take my leave first."

"See you in Paris!"

"See you in Paris!"

Yu Wanzhou returned to the hotel, packed her luggage, and headed for Paris.

When I arrived in Paris, I called Academician Jess, "Hello, Academician Jess."

"Hello, Mr. Yu."

"I'm at the train station in Paris now, how can I get to the Paris Academy of Sciences?"

"Wait, I'll come pick you up right away." Academician Jess put down his phone, left the Academy of Sciences, and drove to the train station to pick up Yu Wanzhou.

Yu Wanzhou hung up the phone and stood there waiting for Academician Jess.

He really came up with a brilliant idea to make some small contributions to the theory of automorphic functions.

The author has something to say: Don't bother with the things in the underworld, and give everyone a big man in popular science, Pope Grothendieck of the Void.
