"I didn't expect us to meet again so soon, it's much bigger than the surprise you gave me last time."

November 25, 2016, Jingzhou City, Jingzhou University, Auditorium Hall.

Xu Yun faced the president of the Mathematical Society for the second time, and still replied with a humble smile on his face.

"I'm looking forward to meeting with you, Academician Yuan, and I want to find an opportunity to ask for advice on some math problems."

He didn't say this as a simple compliment.

As an academician of the Academy of Sciences and the head of the Mathematical Society, Yuan Chengming can have so many titles at a high level, although he proved the world's mathematical problem Hodge conjecture, which has only reached a high level of achievement in algebraic geometry and topology and mathematical analysis.

Other fields still need in-depth study and research, and seek advice from relevant senior professors and scholars.

At first, Yuan Chengming was only satisfied with Xu Yun's performance in the expert interview of the Higher Education Society Cup, and thought that this was a very good seedling.

That's why the Higher Education Society Cup Award was awarded to Xu Yun's team.

I thought it would take a long time to meet again, but I didn't expect Xu Yun to drop a bomb in the mathematics community the day after he won the award.

Wrong.

It's an atomic bomb.

It shook the entire international mathematical community and disrupted many of the original schedules.

For example, he has several university activities that he needs to participate in in the past few days, but in order to ensure the smooth convening of this report meeting, he can only push off all activities and coordinate with Wu Zhongping to escort the report meeting.

At first, when he first received Wu Zhongping's news, his first reaction was that this old friend was joking.

I don't believe that Hodge's conjecture could be suddenly proven, and that the protender has just been seen.

It wasn't until I saw the proof paper on the Hodge conjecture that I was convinced of this fact.

But the shock was just as great.

Even if eight or nine days have passed since the incident, facing Xu Yun at this moment, he still has mixed feelings in his heart.

Fortunately, Xu Yun's performance made him still satisfied, and he did not become unpopular because of this achievement.

It is necessary to know that thousands of high-rise buildings rise from the ground, and only when each floor is used as a foundation to learn and enrich themselves, can they go further and the building is higher.

"The word "consult" is no longer appropriate." Yuan Chengming hurriedly raised his hand and smiled when he heard this, and said, "Although you are still an undergraduate student, your research in the field of algebraic geometry and topology is more profound than that of a professor. ”

"If you have any questions in the future, you can come to me at any time to communicate, and we will discuss learning and improving together."

"I'll look for you when I have a chance." Xu Yun nodded and reassured.

Having said this, Yuan Chengming did not stop talking, but mentioned another thing.

"Also, I would like to invite you to join the Math Society."

"Join the Math Society?"

Xu Yun was stunned for a moment, and repeated the sentence with a slight surprise.

Although the threshold of the Mathematical Society is not very high, under normal circumstances, you can become a full member of the Mathematical Society if you have a member introduction or a recommendation from the unit.

However, being invited by the president of the Mathematics Society is also an opportunity that is difficult for others to have.

Just as he was deep in thought, the familiar voice of the principal Wu Zhongping suddenly sounded in his ears.

"There is no harm in going to mathematics, and when you become a professor in the future, you can run for the position of director."

"Whether our mathematical community can occupy an authoritative position in the international community depends on you in the future."

"What Lao Wu said is not bad at all." When Yuan Chengming heard Wu Zhongping's words, he immediately made a promise: "As long as you are willing to join the Mathematics Society, I promise to recommend you to take my place in the future." ”

Listening to all the words of the two of them, Xu Yun was also full of thoughts in his heart and did not make up his mind.

He always felt that the two of them were suspicious of painting cakes.

After a slight pause for two seconds, he replied loudly: "I just want to finish my studies now, is this burden too heavy?" ”

"The mathematical community doesn't depend on you young people, and it's not like you're going to carry this banner now." Yuan Chengming added a slightly focused tone, and added again without refusal: "Besides, if you are only a full member, you don't need to do anything for mathematics." ”

Hearing this, Xu Yun knew that it would be hypocritical to refuse, thinking that it was just a membership anyway.

The thought stayed here, and he resolutely agreed.

"I'd like to join the math club."

"That's right." Yuan Chengming had a bright smile on his face.

Then, under Xu Yun's surprised gaze, he took out a membership card from his pocket and handed it over.

"I've got your papers ready."

Xu Yun took the certificate and opened it and saw that it was his own photo, and muttered softly with resentment: "If you dare to join me today, you will be a member of the Mathematics Society." ”

It can only be said that ginger is still old and spicy, and these old guys have too many eyes.

Yuan Chengming, who knew that he was wrong, smiled and hurriedly took the initiative to divert the topic: "How are you preparing for tomorrow's report?" ”

He is not worried about Xu Yun's strength, it is mainly the first time to experience such a big battle in the face of hundreds of professors and scholars from home and abroad, if he is too nervous, it is easy to make mistakes.

As for this question, before Xu Yun could speak, Wu Zhongping next to him took the lead in answering.

"Don't worry, Lao Yuan."

"I have already taken Xu Yun to greet most of the people just now, and I shouldn't be nervous when I come to the stage tomorrow."

"That being said, those overseas scholars may not be able to make the report come to a successful conclusion." After listening to Wu Zhongping's words, Yuan Chengming still expressed his concern.

Domestic experts and professors in the field of mathematics will definitely not deliberately make things difficult for Xu Yun at the report meeting.

But it's hard to say overseas.

After all, some people have a lot of opinions about Xu Yun's proof of Hodge's conjecture.

Of course, Xu Yun understood the meaning of Yuan Chengming's words, and he had just greeted many people who came to attend the offline report meeting.

Among them, the dean of the Department of Mathematics of Jinghua University, the vice president of Imperial Capital University, and professors of mathematics from major universities in China, in addition to professors from well-known overseas universities, they also met a lot.

Rao was mentally prepared for a long time, and it was inevitable that he would be a little nervous when facing so many authoritative figures in the mathematical world for the first time.

But his greatest confidence is the Hodge conjecture proof process, no matter what kind of doubts are raised, he can respond forcefully.

"I can prove Hodge's conjecture, and naturally I am sure to preside over this academic report."

"Okay."

"I'm relieved to have your words." Yuan Chengming couldn't help but pat Xu Yun's shoulder and said.

I was very happy with Xu Yun's answer.

As soon as the words fell.

I saw two overseas participants walking towards them.

Judging from their appearance and age, the two should belong to the teacher-student relationship.

Wu Zhongping seemed to know the blonde old man among them, and immediately reminded Xu Yun to inform the other party's identity.

"Xu Yun."

"This is Professor Griffith of the Clay Institute of Mathematics, and he came here from Cambridge on purpose."

Xu Yun is no stranger to the Clay Institute of Mathematics, after all, the seven world's mathematical problems are proposed by them, and the million-dollar prize for each problem is also distributed by the Clay Institute of Mathematics.

Xu Yun nodded to Wu Zhongping, and took the initiative to take two steps towards Griffith, who was coming towards him, out of politeness.

When the other party walks up to the front and stops, stretch out his hand to greet him in a pure English tone.

"Hello Professor Griffith."

"Welcome to this lecture at Jingzhou University."

With the blessing of his oral proficiency, he and any overseas professor can communicate in English without pressure.

Even if it's to discuss complex math problems.

Griffith naturally read Xu Yun's materials before he came, and although he was amazed by such a young probe of the world's mathematical problems, he was still surprised after hearing Xu Yun's spoken language.

Apart from being extremely smooth and confident, there is no other flavor mixed in there.

The whole sentence can only be described in two words.

Purity.

This made him can't help but have a good impression of Xu Yun again.

"Thank you."

"You're the most mathematically gifted genius I've ever met, and now I have more to say about your spoken language."

did not hesitate to praise himself, and after expressing his appreciation to Xu Yun, he introduced the young people around him.

"This is Minter, a researcher at our Clay Institute of Mathematics, who is also a student of mine and has a Ph.D."

"Hello, the genius boy who proved Hodge's conjecture." Minter held out his hand and smiled in response.

Hearing Griffith's introduction, Xu Yun moved his gaze to Minte.

Looking at it, the other party belongs to the kind of handsome Western guy who is quite standard, but the smile on the corner of his mouth and the sentence just now always make him feel weird.

Considering that he didn't stretch out his hand to hit the smiling person, he still reached out and shook the other party shallow to say hello.

"Welcome to Kyonju University."

In the following time, Wu Zhongping talked with Griffith and introduced Yuan Chengming.

But soon Xu Yun discovered one thing, this handsome gringo was actually a talker.

In addition to asking him about his specific age and academic status, he even took the initiative to care about his emotional status, and those who didn't know thought he was checking his household registration.

So taking advantage of the other party's pause, he turned passive into active and asked the other party a question.

"Dr. Minter, I don't know what your research direction is?"

"I'm mainly interested in prime numbers and the Goldbach conjecture, and if nothing else, the next solution to the world's mathematical problems will be me." Minter seems confident in his research and does not hide his truest thoughts.

Xu Yun was still calm when he heard this, and he didn't feel that the other party was boasting about himself excessively.

After all, geniuses always have their own pride, and there is nothing to prove the world's mathematical problems as their biggest goal.

However, this made his mind come alive, and he thought that he had been studying number theory recently, so he planned to exchange ideas with each other.

"Dr. Minter."

"It just so happens that I am also studying number theory during this time, so why don't we go to the side and communicate with each other."

"You're also studying number theory?" A look of surprise appeared on Minter's face.

To be able to prove the world's mathematical problem Hodge's conjecture will inevitably spend a lot of energy and time on algebraic geometric topology, but now Xu Yun says that he is studying number theory.

"Does he want to try to prove other problems?"

The thought quickly came to his mind, and he dispelled it away, and finally nodded in agreement.

Mainly, even if you are a genius, you can prove a world mathematical problem, and you are basically exhausted of inspiration and luck.

It is simply impossible to prove other difficult problems, let alone from algebraic geometry to number theory.
