"I didn't expect that the competition paper I was optimistic about before was actually completed by this guy leading the team."
On April 26, 2017, Xu Yun looked at the latest announcement of the US competition winners list in his dormitory, feeling very surprised and surprised.
After the competition papers selected for the special prize entered his mailbox last month, he deliberately stopped writing his graduation thesis and fulfilled his obligation as a member of the organizing committee to analyze, research and select the competition papers.
In addition to evaluating each paper, the most favorite one was also selected as the winner of the grand prize.
The selection of competition papers is mainly based on ideas and processes as well as model construction and other aspects.
Compared with the domestic Higher Education Society Cup which focuses on process, the International Mathematical Modeling Competition focuses on ideas.
The competition paper he chose was not only novel in idea, but also had no flaws in the process. In addition, the three methods used in model construction made him very impressed.
However, because the way of answering questions was different from that of domestic participating teams, he originally thought it was an overseas group.
Unexpectedly, the team led by Pu Wenxing of Qinghua University, together with Li Wenqing and another member, won the special prize.
You must know that the selection of the special prize requires the support of multiple judges. Pu Wenxing and the others were able to win the special prize, which shows that their answer ideas and processes really conquered the organizing committee.
The last time we participated in the Higher Education Society Cup, the opponent only received the Innovation Award. This time, we made up for our regret by taking home the US Cup.
Unfortunately, Zhou Qi and Zhang Xiaoyuan's team failed to achieve outstanding results.
The ranking you get is at most a consolation prize.
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 they participated in the Higher Education Society Cup. It is difficult to gain an absolute advantage in the international mathematical modeling competition, and it is difficult to win a consolation prize. Participation is not in vain.
On the contrary, Pu Wenxing did a good job in this regard and was able to flexibly change his own and the team's styles.
Soon after he calmed down, considering his status as a judge and his relationship with Pu Wenxing and Li Wenqing, he hesitated for a while before posting the winner's list on Weibo to express his congratulations to their group.
It is worth mentioning that he did not have a personal account other than a company account.
The Mathematical Society proposed to register an account and use your identity and achievements in mathematics to stimulate everyone's passion for learning mathematics.
Thinking that this would not be a troublesome matter, I registered a Weibo account.
The user name is your own name, and the authentication information is only the simple information of membership of the Mathematical Society.
Perhaps due to the popularity brought by the previous proof of Hodge's conjecture, his number of fans reached one million not long after he registered, and most of his fans are college students.
Therefore, not long after the post was posted, a large number of comments appeared underneath.
"The front row looks up to God Xu and bless me not to fail the final exam."
"Can Xu Shen wish me good results in the college entrance examination this year? I also want to go to Jingzhou University."
"Did Qing Hua win the special prize this time? It should have been selected by Xu Shen."
"It's a pity that Xu Shen didn't participate, otherwise he would have won the Higher Education Society Cup and the American Championships."
"Can you help me with my essay? I can pay for it."
…
Xu Yun slid the mouse and glanced casually, then closed the page without any interest in continuing to browse.
Since registering a private account, he has received a large number of private messages every day.
Some asked him for help with math problems, and some posted the original text of a paper for him to revise. The workload was simply more than that of professors in universities.
He is busy writing his graduation thesis, so he naturally cannot have time to help with these things, so basically except for using Weibo, he will never open his login account.
After dealing with the award list, Xu Yun returned his attention to his graduation thesis.
Continue the process of proving the existence of infinite prime numbers in the Fibonacci sequence and write it according to the paper format.
As for the topological group theory method used, 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 paper alone.
Because the entire argument has already been successful, this makes writing the paper very fast.
It doesn't take much effort at all, it's just like copying something.
that's all.
As time passed into May, his undergraduate thesis was finally completed.
And it also includes courseware for 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 answering, and I don’t know how long it will last.”
In a defense room in the Department of Mathematics in late May, Xu Yun organized his courseware and raised his eyes to look at the empty seat in front of him, patiently waiting for the defense committee to enter the room to participate in his defense.
According to the normal tradition of the Department of Mathematics at Peking University, many people often defend themselves one after another.
This is indeed the first time he is defending alone like this. The lineup of key mentors is rare even in the country.
Speaking of which, he still doesn't know how many well-known domestic mathematics professors Qin Xiangxin has found, but he can imagine how brutal and sharp the subsequent questioning session will be.
Fortunately, he wrote this graduation thesis himself and did not ask any teacher to help him revise it. No matter what difficulties he faced, I believe he could always maintain a logical and clear answer with ease.
at the same time.
As a commercial vehicle stopped in the department, Dean Qin Xiangxin, Tang Yanshan and He Antai hurriedly greeted it.
When the car door was opened from the inside, Yuan Chengming got out first, followed by five middle-aged men.
Judging from their hairstyle and temperament, they are obviously senior professors in universities.
"Dean Qin."
"We're not late, are we?"
"Whatever Academician Yuan said, I can't even thank the Mathematics Society for supporting our Department of Mathematics at Peking University." Qin Xiangxin responded with a smile after hearing Yuan Chengming's words.
"Xu Yun is also a member of the Mathematical Society, and attending his graduation defense is what we should do."
Yuan Chengming waved his hand and did not accept the credit. When he mentioned Xu Yun, his eyes were filled with affection.
He has recognized Xu Yun as the person who will promote the development of domestic mathematics in the future, and he wants to take his place and lead the Mathematical Society. He will definitely not refuse the request from Jingzhou University.
What's more, with Xu Yun's achievements, if he doesn't form a higher-standard lineup, he will just be a teacher listening to the defense.
When Yuan Chengming got the news about Qin Xiangxin, he talked about it within the Mathematical Society.
Unexpectedly, many professors signed up enthusiastically. They said they wanted to see what the graduation thesis completed by the Hodge conjecture prover would be like.
After all, Hodge's conjecture has been proved. If the graduation thesis has no academic value, it will not be used.
If it were an ordinary graduation defense for undergraduates from other schools, they would not necessarily participate even if the principal of the other party personally invited them, but Xu Yun was a special exception.
In the end, Yuan Chengming selected five senior mathematics professors from Qinghua and Imperial universities to come to Jingzhou to cooperate with the Department of Mathematics of Beijing University to complete Xu Yun's graduation defense.
"The boy is already waiting in the defense room. Let's go over there." After greeting each other, Tang Yanshan took the initiative to mention it.
The topic turned to business, so everyone said nothing more and headed to the question and answer room under the leadership of Qin Xiangxin and Tang Yanshan.
Since they are both in the mathematics circle and are members of the Mathematical Society, they can be considered familiar with each other.
On the way to the Q&A room, Yugu Cong, deputy dean of the Department of Mathematics at Teito University, took the initiative to ask questions.
"What is the topic of his graduation thesis?"
At this time, Yutani Satoshi was still a little worried. His research field was mainly number theory analysis, and Xu Yun was obviously good at proving Hodge's conjecture in algebra, topology, and mathematical analysis. Under normal circumstances, everyone would choose what they are best at for their graduation thesis. If they can't understand Xu Yun's graduation thesis, it would be an embarrassment to Teito University.
Therefore, before the defense officially begins, it is necessary to have a little understanding and preparation.
Yugu Cong's words were also recognized by several other people, who took over the words and echoed them as they walked.
"Lao Tang is right. Knowing his topic selection at least gives us some mental preparation."
"After all, he is a mathematical genius who proved Hodge's conjecture. It's really wrong not to be serious."
"I'm afraid that we old guys won't even be able to understand it by then. That would be really embarrassing."
"The students today are all very evil."
Tang Yanshan listened to the words of several people, but his face looked slightly embarrassed at this moment.
Because he didn’t know what the topic of Xu Yun’s graduation thesis was?
I organized my words a little, and with a forced smile on my face, I said: "I'm not afraid of your jokes. With my level, I'm afraid I'm not qualified to guide him in writing his graduation thesis, so I won't know the specific topic selection direction until the defense officially begins. "
Hearing this, several people, including Yugu Cong, looked a little sullen, thinking that even Tang Yanshan was not qualified to guide, so the academic value of this graduation thesis would not be low.
Just when a few people were thinking about this, Yuan Chengming, who was walking in front, couldn't help it.
He stopped for a moment, turned around and said with a smile: "You are all well-known mathematics professors in China after all. How can you worry about this and that when participating in an undergraduate's graduation defense?"
"Do not worry."
"As long as that kid doesn't prove any more difficult mathematical problems in the world, there will be no problem in helping him complete his defense at our level."
"When the time comes, we will have to use all our strength to make things difficult."
Regarding Yuan Chengming's words, although everyone wants to say that this is not an ordinary undergraduate, but after thinking about it, it does make sense.
Hodge guessed that it might be difficult for them, but it was impossible for Xu Yun to prove the world's mathematical problems again. If he chose the topic normally, there was really nothing to worry about.
After feeling relaxed again, he followed Tang Yanshan and Qin Xiangxin and finally arrived at the defense room after a short walk.
At the same time, they all thought in their hearts that the difficulty would have to be increased during the question-and-answer session to allow Xu Yun to show his true strength.
High level means high standard. If it were as simple as the graduation defense of ordinary undergraduates, there would be no need for them to come to Jingzhou from the imperial capital.
