"The headmaster suddenly called us over in such a hurry, what do you say you ordered?"

November 16, 2016, Jingju University, Department of Mathematics Laboratory Building.

Dean Qin Xiangxin was talking to Tang Yanshan next to him, and the two came down the stairs together, and some doubts appeared in their eyebrows.

Yesterday, the news that Xu Yun and they won the Higher Education Society Cup Award came, and he was extremely happy.

With this honor, the Department of Mathematics of Beijing University will have more face as the dean of the school in the future.

Don't covet the results of other colleges.

The key is that since last year, he has blown out the cowhide.

Originally, I was really a little worried when I calmed down, afraid that I would not be able to get the trophy back and slap myself in the face, but fortunately, Xu Yun did not disappoint him and successfully led the team to win the highest national award in the mathematical modeling competition.

In the morning, he was thinking about making trophies and holding an award ceremony, and he planned to set a time as soon as possible.

At that time, it is better to invite someone from the organizing committee of the competition to come over and participate as the person who presents the trophy.

As a result, he suddenly received a call from the principal, asking him and Professor Tang to go over as soon as possible, and he seemed to be very anxious about something important.

Usually, the dean of the mathematics department is in charge of him, and it is really rare to be so attentive to the president.

Therefore, he didn't dare to delay, called Tang Yanshan, and the two went to the principal's office together.

"Is it to commend our Department of Mathematics for winning the highest award in the National Mathematical Contest in Modeling this year?"

Tang Yanshan kept walking at the foot of the mountain, and casually gave his guess about Qin Xiangxin's question.

"It's possible." Qin Xiangxin nodded approvingly.

Immediately, the two of them did not delay anything, and immediately accelerated their movements and walked towards the parking area.

The president's office is in the administration building of another campus, and I don't know if it will be the year of the monkey when I walk to it.

Driving through the roads of Jingzhou City, it will take a short time to reach the campus where the president's office is located.

Qin Xiangxin and Tang Yanshan simply sorted out their clothes under the administrative building, and when they went up, they saw that the door of the principal's office was open, so they walked in first and then said hello.

"Principal Wu."

As soon as he finished speaking, Qin Xiangxin looked up and saw that Xu Chongxing from the courtyard was also there, and subconsciously shouted.

"Lao Xu, are you here too?"

Xu Chongxing was standing next to him at the moment, facing Qin Xiangxin's shout, a smile quickly appeared on his face, and he replied in a very envious tone.

"Congratulations, Lao Qin, this time the mathematics department is famous."

Qin Xiang thought that the other party was talking about the Higher Education Society Cup, and suddenly grinned and said quite proudly:

"Next year, your institute will also organize people to participate, maybe you can also achieve good results."

Wu Zhongping was wearing a suit, wearing a pair of transparent narrow-rimmed myopic glasses on his face, and the whole person looked more formal and solemn.

However, after seeing Qin Xiangxin and Tang Yanshan coming, he changed his usual serious style, a smile appeared on his face, and he hurriedly got up and beckoned the two of them to sit down on the sofa next to him.

"You're coming, sit down."

Although Qin Xiangxin felt strange about the principal's attitude today, he still temporarily stopped talking to Xu Chongxing, and several people sat on the sofa next to him.

At this time, Tang Yanshan couldn't suppress his curiosity, and took the initiative to ask after everyone sat down.

"Headmaster."

"Did Dean Qin and I come over today because of the Higher Education Society Cup or did you say that there was any major topic that our Department of Mathematics would like to assist in research?"

"Neither." Wu Zhongping shook his head.

When Tang Yanshan and Qin Xiangxin heard this answer, they couldn't help but be even more curious.

Fortunately, Wu Zhongping didn't like to sell Guanzi, and then told the real reason.

"Last night, the school received a thank you letter from Princeton University on its official mailbox."

"Thank you to us for producing a genius for the mathematical community."

There was a temporary pause at this point, leaving time for Qin Xiangxin and Tang Yanshan to digest the news.

"A thank you letter from Princeton University?"

"Are we a student in the department?"

Qin Xiangxin and Tang Yanshan were shocked at the same time, and a large number of thoughts flashed through their minds in an instant.

Princeton's international prestige is well known to them, and it is not easy to send a thank you letter specifically for someone.

Upon learning of this, Qin Xiangxin's first thought was whether any doctor in the department had made some achievements in mathematics.

Just as he was about to ask further, Tang Yanshan's tentative voice suddenly sounded in his ears.

"Could it be that this genius is my student Xu Yun?"

Tang Yanshan could think that Xu Yun was not only because he was his own student, but also because he knew the level of other people in the main department.

It's almost impossible to suddenly make some academic achievements.

But Xu Yun is different.

In addition to his amazing talent in mathematics and extremely high learning efficiency, he is also the most unexpected special existence.

If you want to get Princeton University to send a letter of thanks, Xu Yun has this probability.

Regarding the answer given by Tang Yanshan, Wu Zhongping smiled and said nothing, but Xu Chongxing next to him nodded and closed the coffin.

"Old Don."

"You're really a good student."

"Xu Yun submitted a paper to the Annals of Mathematics, which was not only accepted by the editorial board, but also urgently published with this month's journal."

"The email from Princeton University is to thank Xu Yun for this paper."

Speaking of this, Xu Chongxing did not hide the envy and joy on his face.

How to say it.

I really wish Xu Yun was a member of their courtyard.

"Is it really Xu Yun?" Tang Yanshan couldn't believe it when he saw that his speculation was confirmed, he paused for two seconds to come back to his senses, and hurriedly confirmed to Wu Zhongping: "His paper was submitted to the Annals of Mathematics and was accepted by the editorial board?" ”

"That's right." Wu Zhongping smiled and nodded.

Tang Yanshan knew that Xu Yun had written a paper in the field of mathematics and submitted it to a journal in the first district of the Academy of Sciences.

But I never expected this journal to be an annual journal of mathematics.

As one of the four major journals in the field of mathematics, although the Annals of Mathematics is divided into the first section of the Academy of Sciences, the difference between them is very large.

Even if he wanted to successfully publish a paper in the Annals of Mathematics, the whole process was not easy.

It takes a long time to prepare.

Not to mention a thank you letter from Princeton University.

"This kid actually gave me such a big surprise." After the shock, Tang Yanshan couldn't help but whisper dotingly, obviously in a very happy mood at the moment.

If his own students can achieve such results, he will only feel a light on his face as a teacher.

At this time, Qin Xiangxin also reacted, knowing that he still underestimated Xu Yun's true level.

Being able to publish a paper in a mathematics yearbook as a sophomore, let alone winning the highest award in the Higher Education Society Cup, and participating in the competition with college students of the same grade, is completely a crushing game.

If you can't get it, that's the problem.

And thinking of what he had just said to Xu Chongxing, an embarrassed expression suddenly appeared on the old face.

"That old Xu, you just congratulated because of the paper?"

"What do you say?"

Xu Chongxing gave Qin Xiangxin a rare look, and replied in a deep voice: "Last year, our institute only won the first prize in the national physics experiment competition, and I will envy your mathematics department for a higher education club cup." ”

Wu Zhongping didn't look at the smile on Qin Xiangxin's face, his eyes still fell on Tang Yanshan.

"Professor Tang."

"I didn't expect your research in algebraic geometry and topology to go so far."

"Xu Yun's thesis has you behind the guidance, right?"

"You've made a great contribution to the school."

Tang Yanshan was thinking about waiting for Xu Yun to come back in the afternoon to ask him, why didn't he say in advance that the journal he submitted was the Mathematics Yearbook, but when he heard President Wu's words, his brain seemed to be emptied in an instant.

He didn't even know which journal Xu Yun was submitting to, let alone revised Xu Yun's paper.

How to talk about the word guidance.

For credits that are not his own, he will never take it from him.

Therefore, he was stunned for a moment, and immediately explained: "The principal really doesn't hide it, this paper was written by Xu Yun alone. ”

"I didn't even know he was voting for the Annals of Mathematics."

"What you say is true?" Wu Zhongping's face changed suddenly, and his expression was very serious.

Although he didn't know what was going on, Tang Yanshan still answered truthfully.

"It's all true."

Once again, Tang Yanshan confirmed that Wu Zhongpingrao was in the position of the president of the university, and the whole person couldn't help but be shocked.

And those with the same expression also include Xu Chongxing, the president of the Academy.

If it were just an ordinary math almanac paper, he would be glad that the school had such a genius.

But he had already read Xu Yun's paper just now.

Although only Xu Yun's own signature was on the paper, he thought that Tang Yanshan's guidance must be indispensable behind it, after all, Tang Yanshan is the most senior professor in the field of algebra in the Department of Mathematics.

As a result, Tang Yanshan's words made him completely subvert what he thought in his heart.

"It's incredible, young and promising!"

"It is the greatest pride of our Jingzhou University to have such students." Following Wu Zhongping's heartfelt emotion, Xu Chongxing couldn't help but answer.

It's just that this made Qin Xiangxin and Tang Yanshan next to him full of question marks.

I thought that even if I published a paper in the Annals of Mathematics alone, I wouldn't have had such a big reaction.

At this time, Wu Zhongping noticed the slightly confused expressions of the two, and quickly reacted to wait for the emotions to calm down a little, and opened his mouth to throw a rhetorical question to them.

"Do you know what Xu Yun's paper is written?"

"The Proof Process of Hodge's Conjecture." As soon as the previous sentence came out, I couldn't help but tell the result.

Almost the moment Hodge guessed that these four words were spoken, including Qin Xiangxin and Tang Yanshan, they stood up suddenly.

The two pairs of pupils can only be described as earthquakes, and in any case, he never thought that Xu Yun would be confident enough to prove Hodge's conjecture, you must know that even he, a senior professor in the field of algebra, would not dare to touch this kind of thing easily, otherwise he might fall into it if he was not careful.

"Headmaster, you're not kidding, are you?" Qin Xiangxin's expression was a little stiff.

As dean professor of the Department of Mathematics, he and Tang Yanshan are well aware of the difficulty of Hodge's conjecture.

Even the most powerful mathematicians in China formed a team, and they did not dare to say that they were sure to prove the Hodge conjecture.

But at this time, Xu Chongxing's words next to him brought them an even greater shock.
