"I didn't expect that the competition paper I was optimistic about before was actually completed by this guy and led the team."

On April 26, 2017, Xu Yun in the dormitory looked at the newly announced list of winners of the American Competition, and looked very surprised in his heart.

After the competition papers selected for the grand prize entered his mailbox last month, he also deliberately stopped writing his graduation thesis and fulfilled his obligation as a member of the organizing committee to analyze and research the competition papers.

In addition to the evaluation of each paper, the most preferred one was selected as the grand prize winner.

The selection of competition papers is mainly carried out from many aspects, such as ideas and processes, as well as the construction of models.

Compared with the domestic Higher Education Society Cup, which focuses on the process, the focus of the International Mathematical Contest in Modeling is on ideas.

In addition to the novel ideas, the competition paper in his photo could not find any problems in the process, and the three methods used in the model construction made his eyes shine and he liked it very much.

However, because the idea of answering the question was different from that of the domestic team, he originally thought it was an overseas group.

Unexpectedly, it was the group led by Pu Wenxing of Jinghua University, and Li Wenqing and another member won the special prize together.

You must know that the selection of the grand prize requires the support of many judges, and Pu Wenxing was able to win the grand prize, which shows that their answering ideas and process have indeed conquered the organizing committee.

The last time I participated in the Higher Education Club Cup, the other party only won the Innovation Award, and this time I won the Meisai Trophy to make up for the regret.

It's a pity that Zhou Qi and Zhang Xiaoyuan failed to achieve excellent results in their group.

The place is considered a consolation prize at best.

But this situation is normal, it can only be said that Zhou Qi and Zhang Xiaoyuan still retain the ideas and methods of answering questions when participating in the Higher Education Society Cup, and it is difficult to occupy an absolute advantage in the international mathematical modeling competition, and it is not in vain to participate in winning a consolation prize.

On the contrary, Pu Wenxing has done a good job in this regard, and has the flexibility to change his own style and that of the group.

Soon after his emotions calmed down, considering his identity as a judge and the relationship between Pu Wenxing and Li Wenqing, he hesitated a little and forwarded the list of winners on Weibo to congratulate the group of the two.

It is worth mentioning that he did not have a private account except for the company account before.

It was the Mathematics Society that proposed to register an account and use his identity and achievements in mathematics to stimulate everyone's passion for learning mathematics.

Thinking that this was not a troublesome thing, I registered a Weibo account.

The username is your own name, and the authentication information is only a simple information about being a member of the Mathematical Society.

Probably the heat brought by the previous proof of Hodge's conjecture, his followers reached one million not long after he registered, and the vast majority of fans were college students.

So not long after the news was released, a large number of comments were refreshed at the bottom.

"The front row pays homage to Xu Shen and blesses me for not failing the final exam."

"Can Xu Shen bless me with a good score in the college entrance examination this year, I also want to go to Jingzhou University."

"Was the grand prize won by Qin Hua this time, it should have been selected by Xu Shen."

"It's a pity that Xu Shen didn't participate, otherwise he would have been able to produce a double championship of the Higher Education Society Cup and the United States Competition."

"Can you help me with the paper, I can pay for it."

……

Xu Yun slid the mouse and glanced at it casually, then closed the page directly, not interested in continuing to browse.

Since signing up for his private account, he has been receiving a lot of private messages every day.

Some asked him for math problems, and some posted the original papers for him to revise, and the amount of tasks was simply more than that of professors in universities.

He is busy writing his graduation thesis, so naturally he can't have time to help with these things, so basically except for using Weibo, he will never open a login account.

After dealing with the list of winners, Xu Yun refocused his attention on his graduation thesis.

Continuing with the process of proving the existence of infinite primes in the Fibonacci sequence, write in the format of a paper.

As for the topological group theory method used in it, it is not explained in depth.

In addition to considering that there is still a lot of room for improvement, I also want to wait until I have time to write a separate paper later.

Because the whole argument has been successful, this makes the paper very quick to write.

It doesn't take much effort at all, it's like copying something.

That's it.

As the time entered May, his undergraduate thesis was finally completed.

It also includes courseware for the defense.

After Tang Yanshan learned the news, he did not review the paper in advance as he said before, but directly determined the defense time with Qin Xiangxin.

……

……

"I'm the only one who defends the defense, and I don't know how long it will last."

In late May, in a defense room of the Department of Mathematics, Xu Yun sorted out his courseware, raised his eyes, looked at the empty seats in front of him, and patiently waited for the defense committee to enter the venue to participate in his defense.

According to the normal tradition of the Department of Mathematics at Kyoto University, many people often defend in turn.

It is indeed the first time that he has defended alone like this, and the lineup of key tutors is rare even in the country.

Speaking of which, until now, he still doesn't know how many well-known domestic mathematics professors Qin Xiangxin has found, but you can imagine how brutal and sharp the question session will be later.

Fortunately, this graduation thesis was written by himself, and he did not let any teacher help revise it, no matter what kind of difficulties he faced, I believe that he can always maintain logical clarity and answer with ease.

Meanwhile.

With a commercial vehicle parked in the department, Dean Qin Xiangxin, Tang Yanshan and He Antai hurriedly caught up.

When the car door was opened from the inside, Yuan Chengming got out of it first, followed by five middle-aged men.

Judging from the hairstyle and temperament, they are obviously senior professors in colleges and universities.

"Dean Qin."

"We're not late, are we?"

"Whatever Academician Yuan said, the Mathematics Society is willing to support our Department of Mathematics of Beijing University, but I can't be grateful." Qin Xiangxin heard Yuan Chengming's words and hurriedly responded with a smile.

"Xu Yun is also a member of the Mathematics Society, and it is what we should do to participate in his graduation defense."

Yuan Chengming waved his hand and did not take the credit, his eyes were full of love when he mentioned Xu Yun.

He has recognized Xu Yun as a person who will promote the development of mathematics in China in the future, and he will take his place to lead the Mathematics Society, and he will definitely not refuse the request of Jingzhou University.

What's more, with Xu Yun's achievements, if he doesn't form a high-standard lineup, he is afraid that he will become a teacher in the defense.

When Yuan Chengming first got Qin Xiangxin's news, he talked about it within the Mathematics Society.

Unexpectedly, many professors enthusiastically signed up, according to their words, they all wanted to see what the thesis completed by the Proof of Hodge's conjecture would be.

After all, it all proves Hodge's conjecture, and if the dissertation is too unacademically worthless, it can't be used.

If it is the graduation defense of ordinary undergraduates from other schools, then even if the other party's principal personally invites them, they may not necessarily participate, but Xu Yun is a special exception.

In the end, Yuan Chengming selected five senior mathematics professors from the two universities of Jinghua and Imperial Capital to come to Jingzhou to cooperate with the Department of Mathematics of Beijing University to jointly complete Xu Yun's graduation defense.

"That kid is already waiting in the defense room, let's go over." After greeting each other, Tang Yanshan took the initiative to mention it.

When the topic got down to business, everyone didn't say anything more, and went to the Q&A room under the leadership of Qin Xiangxin and Tang Yanshan.

Since they are both in the circle of mathematics and are members of the Mathematical Society, they can also be called familiar with each other.

On the way to the Q&A room, Satoshi Tangtani, deputy dean of the Department of Mathematics of Imperial Capital University, took the initiative to ask questions.

"What is the direction of his graduation thesis?"

At this time, Tang Gu Cong was still a little worried, his research field was mainly number theory analysis, and Xu Yun was able to prove that Hodge's conjecture was obviously best at algebra and topology and mathematical analysis. Under normal circumstances, the graduation thesis will choose what you are best at, if you can't understand Xu Yun's graduation thesis at that time, it will be a shame for Imperial Capital University.

Therefore, it is necessary to understand a little bit of preparation before the defense officially begins.

And Tang Tani's words were also agreed by several other people, and they took over the conversation and echoed it as they walked.

"Lao Tang is right, knowing that his topic selection at least makes us a little mentally prepared."

"After all, he is a mathematical genius who proves Hodge's conjecture, and he really can't be serious if he is not serious."

"I'm afraid that when the time comes, a few of our old guys won't even be able to understand it, and it will be a real shame."

"The current students are very wicked."

Tang Yanshan listened to the words of several people in his ears, but his face was slightly embarrassed at the moment.

Because he doesn't know what the direction of Xu Yun's graduation thesis topic is?

organized the language a little, and said with a smile on his face: "I'm not afraid of your jokes, I'm afraid I'm not qualified to guide him to write his graduation thesis at my level, so I can't know what the specific topic direction is until the defense officially begins." ”

Hearing this, the expressions of several people, including Tang Gu Cong, were a little stagnant, thinking that even Tang Yanshan was not qualified to guide, so it seems that the academic value of this graduation thesis will not be low.

Just when a few people wanted to think about this, Yuan Chengming, who was walking in front, couldn't help it.

He stopped for a while, turned around and said with a smile: "You are all well-known mathematics professors in China, how can you participate in the graduation defense of an undergraduate, you are worried about this, worrying about that." ”

"Don't worry."

"As long as that kid no longer proves the world's math problems, there is no problem in helping him complete the defense at our level."

"When the time comes, I'll have to make it hard."

Regarding Yuan Chengming's words, although everyone wants to say that this is not an ordinary undergraduate, it does make sense when you think about it.

Hodge's conjecture may be difficult for them, but Xu Yun can't prove the world's mathematical problems again, but there is really nothing to worry about if the topic is selected normally.

After re-relaxing, he followed Tang Yanshan and Qin Xiangxin for a short time and finally arrived at the defense room.

At the same time, they all thought in their hearts, waiting for the questioning session to increase the difficulty so that Xu Yun could show his true strength.

A high level represents a high standard, and if it is really as simple as the graduation defense of ordinary undergraduates, they will not need to come to Jingzhou from the imperial capital.
