Chapter 846: The Students Can’t Win, so the Instructors Kill Them Randomly?

"Professor, there is Tong Yang's defense this morning, which will be held in Room A2 of the Mathematics Building."

In the office, assistant Tang Ran knocked on the door and quickly reported.

At the desk, Xu Chuan put down the signature pen in his hand, nodded and said: "Yes, I understand."

He agreed to Tong Yang's graduation defense, or in other words, he would usually appear for every accepted student's graduation defense unless there were special circumstances.

In fact, according to general regulations, students' graduation defense generally has a system for avoiding instructors, but the implementation methods of each school are also different.

In some schools, tutors may not be present throughout the process, in some schools they may be present but silent, and in other schools, tutors may help students supplement knowledge points or experimental data.

This varies in different schools and different majors.

As for his side, the situation is rather special.

For the three students who have already graduated, the defense process is different from that of ordinary graduates.

Whether it was Amelia, Gu Bing, or even Cai Peng, strictly speaking, the first three did not follow the formal defense process.

After all, these three people all gave one-hour and forty-five-minute reports at the International Congress of Mathematicians.

And in the entire Nantah University, those with this qualification can count even a forty-five-minute report with a slap in the face.

In this case, rather than reviewing their defense, it is better to ask questions at the defense site.

So strictly speaking, Tong Yang's graduation defense was the first formal defense.

As a mentor, he should stand up for his students.

Along the tree-lined path of the campus, Xu Chuan came to the downstairs of the Mathematics Teaching Building.

Before he could enter, a cheerful voice came from the side, with some teasing and laughter.

"Hey~, isn't this Academician Xu a very busy man? Why are you free today?"

Following the sound, two middle-aged and elderly men came over from the other side. Seeing the coming people, Xu Chuan smiled and said hello.

"Academician Zhang, Director Zhou."

The visitors were all acquaintances. The former was Academician Zhang Weiping from Fudan University, and it was he who had just spoken out. He had known Xu Chuan for a long time, and they knew each other well because of their work in information security in high school.

The latter is Professor Zhou Hai, formerly a professor in the Department of Mathematics at NTU and now the director of the School of Mathematics.

"I thought you wouldn't come today, but I didn't expect you to be a primary school student." Zhang Weiping walked over with a smile and said with a smile.

Xu Chuan suddenly reacted, looked at Academician Zhang, and asked, "Can you be?"

Zhang Weiping smiled and said: "Why, can't you?"

Xu Chuan smiled and shook his head and said, "I didn't expect Tong Yang to be so honored to have an academician as the defense judge."

He really didn't expect that Zhang Weiping, Academician of Fudan University, would come over to attend Tong Yang's graduation defense.

After all, people at the level of academicians each have their own research or projects, and there are really not many who can run around.

Hearing this, Zhang Weiping smiled and said: "Let's go up first. I guess the others should have arrived early."

"Others?" Xu Chuan's eyebrows skipped a beat. He looked over and felt something was wrong.

Zhang Weiping smiled mysteriously and said: "Of course they are the other defense judges. You must know that I managed to get this spot."

"Rob?"

Xu Chuan was stunned for a moment, looked at Professor Zhou Hai and asked, "Director Zhou, who are the judges for today's defense?"

Although he agreed that Tong Yang would participate in his doctoral defense, he didn't really ask who would be on the defense committee. He thought it would just be a few professors from the mathematics department, so he didn't pay much attention to it.

Looking at it now, something seems a little wrong?

Zhou Hai coughed lightly and said with a smile: "We are all acquaintances, don't worry."

Seeing that the two of them were mysterious, Xu Chuan felt a little curious, but he didn't pay too much attention.

It was just a doctoral defense. He had read the thesis and there were no problems. The defense process was almost complete.

It wasn't until he entered the defense classroom that Xu Chuan realized what Professor Zhou Hai meant when he said they were acquaintances.

Good guys, we are all acquaintances.

Academician Zhang Weiping from Fudan University, Academician Qiu Chengtong from Shuimu University, Academician Zhang Gongqing from Peking University, Academician Chen Zhiming from the Academy of Sciences, Academician Li Jun from the Shanghai Institute of Mathematics and Interdisciplinary Studies, plus Rong Zhizhuan, dean of the School of Mathematics at NTU.

Indeed, they are all acquaintances, they have dealt with each other before, and they communicate with each other through letters and phone calls.

But Xu Chuan really didn't expect that these people would come together.

When he graduated, he didn't have such a big fight.

There are six defense judges, five academicians, and one dean of several colleges. If he, the mentor, had not come, Tong Yang would probably cry on the spot.

"haven't seen you for a long time."

Seeing Xu Chuan, Academician Zhang Gongqing from Peking University walked up to him with a smile, stretched out his hand to shake it, and said with a smile: "The last time we met was at Princeton. We haven't seen each other for many years."

"Academician Zhang, long time no see. I didn't expect you to come here too."

Xu Chuan smiled and stretched out his hand to shake the old man in front of him, who was a little thin and had a thin face.

Although the other party is from Peking University, it can only be regarded as a temporary position. Strictly speaking, he is from the Chinese Academy of Sciences, and his relationship with him is not shallow.

When he first entered NTU and solved the problem of weak Weyl_Berry conjecture, Academician Zhang had been to NTU.

Later, when he proved the Hodge conjecture at Princeton, Zhang Weiping gave him a gift, which included a large part of the questions for proving the Hodge conjecture. It was the academician Zhang Gongqing who proposed it. It was a big favor.

Zhang Gongqing smiled and said: "It just so happens that there is something going on in the Magic City during this time. I heard from Qiu Chengtong that one of your students has graduated, so we came over to have a look."

Opposite him, Qiu Chengtong smiled in this direction, with an expression on his face that didn't deserve a beating.

The corners of Xu Chuan's mouth twitched and he said, "This is really Tong Yang's honor."

Zhang Gongqing laughed and said: "His papers were published in "New Advances in Mathematics". They are very good. I really envy you. The students you brought out even won the Philippine Prize."

Xu Chuan: "I hope Mr. Zhang will show mercy."

Zhang Gongqing said with a smile: "Show mercy? How can you show mercy? When he can't beat him later, you go up and kill him randomly?"

"Ahem~" Xu Chuan coughed slightly and said with a smile: "Mr. Zhang really follows the trend."

Zhang Gongqing shook his head and said with a smile: "The world belongs to young people."

The graduation defense began quickly with a few people chatting.

Tong Yang, dressed in a very formal suit and leather shoes, walked up to the podium with a nervous look on his face.

Although his mentor is Xu Chuan, the caliber of the defense judges is probably unprecedented in the country. He is definitely nervous. No one knows what kind of questions these big guys will ask.

The only thing that made him feel slightly reassured was that his mentor was sitting below.

I hope I can 'catch' him at a critical moment.

With an uneasy mood, Tong Yang began to formally defend.

PPT starts showing.

After following the self-introduction process, he began to describe his paper and briefly reported the main points and conclusions of the paper.

This process is very short, only five or six minutes.

The next question-and-answer session is the focus of the defense.

Looking at the big guys sitting under the stage, Tong Yang's heart was beating anxiously.

In the classroom, the first person to raise his hand to ask a question was Qiu Chengtong. He asked straight to the point:

"In the ninth line of page seven of the paper, when you define the mapping process of the natural frame in the Euclidean space R, you use extremal hypersurfaces and minimal surfaces to connect. Can you explain this in detail? "

"Page seven, line nine?"

Taking a deep breath, Tong Yang quickly turned the paper to the place pointed by Academician Qiu Chengtong, and his brows immediately furrowed.

Without him, this position was exactly where Xu Chuan put forward his optimization suggestions when he first showed his graduation thesis to his tutor.

Pursing his lips, Tong Yang raised his head and said, "Can I use the blackboard?"

"Of course." Qiu Chengtong nodded.

"Suppose x:M→R^n+1 is a locally strictly convex hypersurface, given by a strictly convex function xn+1=f(x1, x2,...,xn) defined on a convex domain Ω R^n Out, assuming Y = (0, 0,..., 0, 1) is the classical relative method of the hypersurface, then the corresponding co-method field"

Looking at Tong Yang writing on the blackboard, Qiu Chengtong narrowed his eyes, nodded approvingly, and said, "Very good."

Not to mention that it is required by a doctoral student's graduation defense. This exquisite simplified idea is still very good even if it is applied to a full professor.

Not to mention the entire paper, at least this section can be said to be very good.

After briefly explaining what Qiu Chengtong asked, standing on the podium, Tong Yang hesitated before speaking:

"The idea for this section actually did not come from me, but from my mentor. It was he who proposed the optimization direction of this section and the relevant proof was obtained."

Hearing this, several defense judges in the audience looked at Tong Yang in surprise, with some praise in their eyes.

In the whole paper, there is no doubt that the most essential one is the proof of this paragraph.

Even they may not be able to think of using extremal hypersurfaces and minimal surfaces to connect the mapping defined under the natural frame in the Euclidean space R.

After all, mathematical research does not mean that if you are a master, you will be able to find all the optimal routes.

Originally, they thought that Tong Yang had completed this step independently, but they did not expect that the idea came from Xu Chuan.

However, looking at the entire paper, this is indeed somewhat different from the proofs in other places, and it is the most prominent point.

Of course, being able to bravely tell the truth during the defense process is commendable enough.

After all, he doesn't need to add any additional information, and I believe Xu Chuan will not take the initiative to say it.

But for academic research, sticking to your heart is an excellent virtue in itself.

Compared with a small piece of excellent proof, the latter is what these academicians value more.

With some praise in his eyes, Academician Zhang Gongqing from Peking University smiled and said, "I'll also ask two questions."

"Excuse me, teacher."

To Tong Yang's expectation, although there were five academicians participating in his graduation defense, the entire defense went extremely smoothly.

Although each academician asked a question, these questions were not difficult for him who had prepared a whole week in advance.

The defense soon came to an end. At this time, Academician Zhang Weiping of Fudan University smiled and said: "It is an excellent proof and a very outstanding paper. You have made great progress in analytic geometry and Riemann manifold optimization and its application. Have you considered continuing research in this area?"

"It just so happens that there is a similar research project at the School of Mathematics of Fudan University. If you are interested."

On the side, Rong Zhizhuan, the dean of the School of Mathematics of Nanjing University, who had been silent all the time, coughed and interrupted him: "You have so many talents in the School of Mathematics of Fudan University. This is a student of Nanjing University. Are you embarrassed?"

Academician Zhang Weiping laughed and said: "With so many talents, it is convenient to communicate, learn and conduct in-depth research. Dr. Tong Yang is very suitable to come to Fudan for research. School of Mathematics of Nanjing University"

Although it was not said explicitly, everyone knew the meaning of Zhang Weiping's words.

Although the strength of the School of Mathematics of Nanjing University has developed rapidly in recent years, it is still far behind the top universities in China.

After all, it is not so easy to dig out or cultivate top mathematics professors.

However, Rong Zhizhuan was furious when he heard this. He frowned and stared at Zhang Weiping and said unhappily: "What's wrong with the School of Mathematics of Nanjing University? The School of Mathematics of Nanjing University has the Fields Medal, does your School of Mathematics of Fudan University have it?"

Zhang Weiping's mouth twitched. How to respond to this?

But he didn't say anything. Rong Zhizhuan didn't intend to let him go. He just continued:

"The School of Mathematics of Nanjing University has the Nobel Prize, does the School of Mathematics of Fudan University have it?"

"The School of Mathematics of Nanjing University has the Crafford Prize, does the School of Mathematics of Fudan University have it?"

"The School of Mathematics of Nanjing University has it"

Seeing that Rong Zhizhuan was about to continue, Zhang Weiping interrupted and said: "Stop, stop, stop, you old man, you attribute all the glory of Xu Chuan to your School of Mathematics of Nanjing University, do you have the nerve to do that?"

Rong Zhizhuan: "Why, what's the matter? Xu Chuan is not a full professor of my School of Mathematics?"

Zhang Weiping: "."

MMP, if you have the ability, you can put Xu Chuan aside for comparison!

What kind of ability is flipping the table?

Academician Chen Zhiming of the Huazhong University of Science and Technology came over and said with a smile: "This guy went to the Huazhong University of Science and Technology to kidnap someone before, and almost told a researcher in my laboratory to leave. This time, he got humiliated."

Aside, Qiu Chengtong smiled and poked Xu Chuan, saying: "I remember that Lao Zhang also tried to get you to Fudan a few years ago, right? This guy still has the bad habit of trying to get people everywhere."

Xu Chuan held back his laughter and couldn't answer this.

After all, they were all elders, and Zhang Weiping was still very good to him.

Besides, Qiu Chengtong has done a lot of things like getting people everywhere.

When he didn't return to China, he wanted to get him to Shuimu to compete with Peking University several times, so don't laugh at each other.
