He ​​who can solve problems is certainly a master. But he who can ask reasonable questions also must be a master. In the history of mathematics, there are countless names of mathematical masters associated with problems: Fermat's Hypothesis, Riemann's Hypothesis, Poincaré's Hypothesis, Wei's Hypothesis

Conjecture, Hilbert's problem... The director of the Royal Mint once pointed out that without bold conjectures, great discoveries cannot be made. In the same way, if a student can make up his own questions without using any problem sets,

A set of test papers with rich content, moderate difficulty, and clear levels means that he must have a very thorough grasp of the knowledge points of the course.

Xu Shengzhou has recently read so many literature materials provided by Mr. Cheng, and is confident that he has a relatively thorough understanding of some branches of probability theory. Coupled with the mathematical vision cultivated in algebraic geometry and abstract algebra, he can come up with several in-depth and valuable articles.

The topic is definitely not a problem.

It was Xu Shengzhou's job to set the questions, and it was Ren Hongshan's job to answer the questions. Xu Shengzhou would not help him anymore. After all, there are academic standards here. If Xu Shengzhou even told him how to solve the problem, it would not be helping him, but harming him.

Him!

In the next few days, Xu Shengzhou was very busy, first filling out the defense application form, and then submitting the defense application. Fortunately, Mr. Cheng from the school had already said hello, and the technology and personnel departments were not too embarrassed. As for training,

The computer department of the unit even got the green light. While Xu Shengzhou was in retreat reviewing his thesis, making PPTs, and concentrating on preparing for the defense, Mr. Cheng also finalized the candidates for the defense committee.

When Hengping sent the list over, Xu Shengzhou's eyes suddenly dazzled, because the lineup was so luxurious, as if it was studded with crystal clear diamonds! The chairman of the defense committee is Academician Bai Cihe of the Institute of Mathematics. The old man should be seven

He is already in his teens. He not only became famous early, but also has a high seniority. It is said that he once attended Grothendieck's class and is the pioneer and founder of algebraic geometry in China. The committee members include Academician Tian Ziliang of Yan University and Mr. Cheng himself,

As well as two outstanding young people, Wei Zishu from Jimen Normal University and Yu Xiaohe who studied in the United States, almost all the famous celebrities in the field of algebraic geometry in Beijing are included.

Heng Ping was a little jealous: "Not to mention a master's degree, not many even a doctorate can get the treatment you do!"

Xu Shengzhou also felt very glorious: "Who can I invite? Isn't it because of the great dignity of the old man?"

"Then only if others are willing to come. For example, Tian Ziliang has such a big name, high status, and strong background that ordinary people can't even hire him! But in order to suppress him, Mr. Cheng even went to Mr. Bai, who rarely shows up.

We invited them all. When Tian Ziliang went abroad, Mr. Bai wrote a letter of introduction for him and contacted the school. He was so kind! If it weren't for Mr. Bai, I'm afraid others wouldn't be able to control him."

Only then did Xu Shengzhou understand why he put Mr. Bai first.

Heng Ping pointed to the list again and said: "Look, Mr. Bai is considered the first generation of algebraic geometry in the country, Tian Ziliang is the second generation, Wei Zishu and Yu Xiaohe are the third generation, and you are the fourth generation. The fourth generation

We are in the same room!"

"Then which generation do you belong to?"

"Me? I'm considered the 3.5th generation now, right? If I can get into the elite ranks in the next ten years, I can squeeze into the third generation. If I can't get into the ranks, I'll be considered the fourth generation - no, there's no need to rank me by seniority.

."

Xu Shengzhou nodded and patted Heng Ping on the shoulder: "When I study for my Ph.D., I will study with Academician Qiu Xindong for a period of time. It can be regarded as joining the Qiu family and becoming the junior disciple of Academician Tian Ziliang. In terms of seniority, I should also be

Second generation, when the time comes, Mr. Heng, you can call me 'Uncle Master' and your third generation will be promoted, right?"

"Go away! I have half-a-master friendship with you. It's good that I didn't let you become my master. You still want to be my uncle, and you want to rebel against you!"

Xu Shengzhou looked at the list again and asked with some confusion: "Who is the defense secretary?"

Hengping said angrily: "I'm standing in front of you and I don't even see you? Yes, it's me!"

As soon as the defense committee list was announced, it not only caused a strong response in the mathematics circle in Beijing, but also caused a lot of heated discussion in the private message circle. It was hailed by many people as "the strongest master's thesis defense lineup." On the day of the defense, Xu Shengzhou

It was rare for him to put on a crisp suit and shiny leather shoes, giving him a sense of immediacy as if he was attending a wedding. He was fine, but Ren Hongshan was like a female cat in spring, walking around restlessly in the dormitory, reminding him of this and other things.

That.

Xu Shengzhou was annoyed by him: "Can't you sit down for a while?"

"I'm so nervous that I can't sit still!"

"It's me who is defending, not you, why are you so nervous?!"

"Have you heard of that song, "Happy for You and Worry for You"?"

"..."

Xu Shengzhou decided to go to the defense scene in advance to avoid this guy with a rough appearance and a stuffy heart. Unexpectedly, he arrived at the scene more than an hour early, and there were already many people in the classroom. It was not clear whether they were here to observe or just join in the fun.

There was even a reporter holding a very exaggerated SLR camera, clicking and clicking randomly. Then he saw a familiar big belly and couldn't help but lost his voice in shock: "Director Zhao, why are you here?"<

/p>

Zhao Chen's big, plump face smiled broadly: "Look, this is not only a major event in your life as a leader, but also a major event in the development of the school. How can we not come and witness it?"

Us? Xu Shengzhou quickly looked behind him and found that Huang Gaohua, He Xinghua, Tao Wenxia, ​​and even Wen Lixiang and He Yuanying were also here to join in the fun. Are you here in a group? I can give you a vaccination and go back and forth for board and lodging.

Take care of yourself!

Huang Gaohua advised with a serious face: "Brother Zhou, please hold back on this argument!"

"Why?" Xu Shengzhou was puzzled.

"Have you forgotten? Last time you defended, you made an old man pass out with anger. Just now I looked at the list of today's defense committee, but there were three old men, and two of them were over seventy years old. You

If I don’t keep this in check, I’m afraid someone might die.”

This chapter is not over yet, please click on the next page to continue reading!

"..." Xu Shengzhou was speechless again. You are not here to cheer me up, but you are trying to make things difficult for me!

At this time, I saw the advantages of being a soft girl. Others were watching the excitement and didn't mind it. Only Wen Lixiang held Xu Shengzhou's arm and said warmly: "Brother Shengzhou is the best! There will be no problem in the defense! Come on!

!"

Don't bully your friend's wife.

Xu Shengzhou recited silently three times, then pulled out his arm without leaving any trace, and asked strangely: "Why are you here too? If I remember correctly, you are a junior, right? Shouldn't this semester be very busy, there are many professional courses?"<

/p>

"Hey, you can miss professional classes, but you can't make them up; for such a major and memorable life event, once you miss it, you can't make it up."

Well, you are so full of tea that it’s hard for me to answer the phone! Fortunately, Heng Ping appeared at this time and helped him out: "Hey, why are you hiding here? Let me find you easily. Hurry up and follow me

Come on, Mr. Bai is here, Teacher Cheng wants you to meet him."

Xu Shengzhou did not dare to neglect, waved his hands to everyone, and hurriedly followed Hengping to see Academician Bai Cihe. Mr. Bai had silver hair, his face was covered with age spots, and he had a rich figure. He was wearing a thick winter coat and was lying on the sofa, looking like an old man.

I was talking to him. I had only seen him in reference books before. I didn't expect to see him today. Xu Shengzhou quickly stepped forward to say hello: "Hello, Academician Bai!"

Mr. Cheng introduced from the side: "Brother Bai, this is my student, Xu Shengzhou."

"Xiao Xu, right?" Mr. Bai bowed slightly on the sofa and pointed to the chair next to him for Xu Shengzhou to sit down. "I heard from Mr. Cheng just now that you used to major in computer science. Last year, you made an exception and entered the mathematics department?

Are you also studying the direction of algebraic geometry?"

Xu Shengzhou replied respectfully: "You are right. I used to study computers. I was interested in mathematics as a hobby. I thought about it and wrote some papers. Unexpectedly, I got the title of Teacher, Dean Zhang, and Mr. Zhang from the Mathematics Institute of our school.

With the recognition and help of my teacher and teacher Heng, I made an exception and got a graduate degree, otherwise I would be a programmer now."

Mr. Cheng smiled and said: "He is so humble! The first paper he wrote casually was published in last year's "Mathematical Monthly" and was named the best paper of the year. Later he wrote several more articles and simply submitted them to "Mathematics Monthly".

Invent. Math.", it was actually published. Brother Bai, you said that such a student is not exceptional, but who is? Fortunately, we are close and can act quickly, otherwise we would be poached by Yanda and Liumei."<

/p>

Mr. Bai said: "You can publish "Invent. Math." through self-study. You are indeed a good candidate. Of course, if you are not a good candidate, you will not learn the direction of algebraic geometry. As we all know, algebraic geometry is difficult to get started. After two or three years of study,

There are a lot of papers that I can’t understand yet. Xiao Xu was able to complete his master’s thesis after half a year of studying, which is really amazing. By the way, did you publish any academic results during your graduate studies?”

Xu Shengzhou suddenly felt a chill in his heart.

It seems that Mr. Bai has not read his thesis at all, otherwise he would not have asked this question, because at the end of the thesis there is "Scientific Research Results and Academic Papers During the Study of Master's Degree Students", which specifically lists the publications he has published

The situation of the paper. I'm afraid that today's Mr. Bai is like a nuclear weapon, and the greatest significance of its existence is to deter.

Xu Shengzhou forced a smile and said: "Because I only studied for half a year, I only published two papers."

Mr. Cheng couldn't help laughing out loud: "Brother Bai, I am too humble as a student. He has only published two papers, but one is "Ann. Math." and the other is "JAG".

Is this level enough for a graduate student?"

Mr. Bai also struggled to sit up on the sofa and said: "Enough, enough! He has published two "Four Big" articles at a young age. He is really a young talent!"

Mr. Cheng added: "Xiao Xu, you are just a few years late because of your fate. If earlier, Mr. Bai had not suffered from macular degeneration and his eyesight was not bad. If you asked him to give you some advice on your thesis, you would definitely be able to do better."
