Xueba starts with change

Chapter 182 This interview...

When Chen Zhou observed the old man, the old man also observed Chen Zhou with great interest.

Looking at each other, Chen Zhou politely smiled at the old man, and the old man also smiled kindly.

Just when Chen Zhou was thinking about whether it was time for these judges to come up with a question.

I saw a person next to Mr. Qiu whispering a few words to Mr. Qiu.

The old man said a few words to the man with a smile, and then Chen Zhou saw the man looking at him.

The man looked at Chen Zhou, and slowly asked in English, "Tell me briefly how to prove that the group of order 150 is not simple."

Did you start with algebra?

Chen Zhou was slightly surprised.

This problem can only be regarded as the basic content of abstract algebra.

The idea is also very simple, just start with Ciro's theorem.

But to his surprise, the difficulty of the interview doesn't seem to be high?

After organizing the language a bit, Chen Zhou began to use English to state his answer to the question fluently: "First, 150=2×3×5^2. According to Sylow's theorem, Sylow 5 groups exist and are conjugate to each other..."

Chen Zhou talked about it in a calm and eloquent tone.

The overall idea and the details are taken care of very comprehensively.

Because of this, following Chen Zhou's narration, many judges nodded slowly.

"...This contradicts the Lagrange theorem about the order of subgroups, so it can be proved that the group of order 150 is not a simple group."

After Chen Zhou finished answering, he politely expressed his gratitude to the judge who asked the question, and then waited for the next question.

The judge nodded in satisfaction, and then communicated in a low voice with Mr. Qiu beside him.

Often such the simplest questions are the most able to examine a person's proficiency in knowledge.

And Chen Zhou's answer fully demonstrated his familiarity with knowledge.

After communicating with Mr. Qiu, the judge raised his head and looked at Chen Zhou again. Instead of being stern, he smiled and said, "This is the only question I have. I am very satisfied with your answer. In addition, there is a contest A friend asked me to ask other questions."

Although Chen Zhou was puzzled, he said politely: "Please tell me, if it does not violate the rules of the competition."

The man smiled again: "Don't worry, haven't I already communicated with you just now, so I won't delay you from winning the gold medal."

Hearing this, Chen Zhou smiled embarrassedly.

This person stopped talking nonsense and asked directly: "How far has your research on complex partial differential equations progressed?"

Hearing this, not only Chen Zhou was stunned, but even many judges on the judging panel were also stunned. What kind of problem is this?

Complex partial differential equations?
Isn't this kid an undergraduate?How did you start researching such a super-classical problem?
Thinking of the identity of the person who asked the question, these judges couldn't help guessing in their hearts.

However, except for these judges who don't really understand the purpose of this interview.

Other people who knew why they discussed Chen Zhou's interview alone looked at Chen Zhou with interest, waiting for Chen Zhou's answer.

Mr. Qiu himself was also waiting for Chen Zhou's answer.

Chen Zhou also reacted at this time.

Complex partial differential equations, isn't that what he mentioned in the research paper Clifford analyzed?
In addition to what the judge said, he asked on behalf of a friend.

Chen Zhou thought of a lot in an instant.

Regardless of whether this friend is real or not, at least this paper, the judge in front of him has probably read it.

Chen Zhou couldn't help guessing, is there any problem with the thesis?
Isn't it all over the manuscript, waiting for publication?

Chen Zhou finally decided to answer according to the paper.

He talked about the obtained Cauchy integral formula of the right canonical function and the functional properties of related operators, and some theoretical foundations established for solving complex partial differential equations.

Hearing Chen Zhou's answer, the judge nodded: "Okay, I will tell my friend the truth. I have no problem."

After finishing speaking, he turned his head and communicated with Mr. Qiu in a low voice.

Chen Zhou was puzzled again. Didn't you say that the interview for each subject is three out of five?This can only be regarded as a problem, right?

And it still gives points...

Different from Chen Zhou's doubts, after hearing Chen Zhou's answer and the judge's words, the expressions of the other interview judges, whether they knew the truth or not, became strange.

Before making Chen Zhou wait too long, Mr. Qiu signaled to the judges of other subjects to ask questions.

For the remaining four subjects of analysis and differential equations, geometry and topology, introduction and statistics, and applied and computational mathematics, the four judges asked four questions one after another.

The more Chen Zhou answered, the more he felt that something was wrong. Why did four people ask four bonus questions?
It made Chen Zhou think that he had a relationship with the judges, and they were deliberately throwing water...

After Chen Zhou finished answering all the questions, Mr. Qiu told Chen Zhou that he could leave.

Although Chen Zhou was a little confused, he still greeted him politely and prepared to leave the venue.

At this time, Old Mr. Qiu stopped Chen Zhou again: "Student Chen Zhou, I have an extra question."

Chen Zhou turned around and stood up again: "Professor, please tell me."

Mr. Qiu asked, "What do you think mathematics is?"

Chen Zhou was taken aback for a moment, feeling even more confused. After asking so many sub-questions, is this another philosophical question?
What is math?
In layman's terms, isn't mathematics just arithmetic?
To put it esotericly speaking, mathematics is the description of existing quantities and existing changes, and the method and process of verifying quantities and changes.

But this is obviously not Mr. Qiu's answer...

Chen Zhou glanced at this group of inexplicable judges, but they were looking at him with curious eyes.

Chen Zhou has a big head.

After a little hesitation, Chen Zhou said: "All applied sciences must start with pure science. All pure sciences must start with mathematics. Mathematics is the cornerstone of natural science and applied science, as well as the foundation of modern science and technology. It is also an important indicator for judging the comprehensive strength of a country."

The judges in the jury seat, upon hearing this, turned their gazes to the old man in the middle.

Staring at Chen Zhou, Mr. Qiu smiled and praised: "Well said, mathematics is pure, but it is not pure."

Now, no one stopped Chen Zhou, and he left the venue smoothly.

Before leaving, Chen Zhou took a special look at the name tags of those who gave him points in this interview.

After reading it, Chen Zhou felt even more confused.

Next to Mr. Qiu, the one who was asking questions on behalf of a friend was Professor Zhang Shouwu from Princeton University. The next four subjects were Professor Wang Fei from Huaguo Academy of Sciences, Professor Shu Wangqi from Brown University, and Yan Anjia from Huaguo Academy of Sciences. Professor and Professor Feng Liu of UCLA.

These are all well-known mathematicians, especially Professor Zhang Shouwu, who proved the "Bogomolov Conjecture" and promoted the Gross-Zakia formula.

After Chen Zhou left, Zhang Shouwu turned his head again and said to the old gentleman beside him, "How is it?"

Old Mr. Qiu said bluntly: "Exceeded my expectation."

Hearing this answer, Zhang Shouwu was slightly surprised.

In their previous internal discussion, Mr. Qiu had already given Chen Zhou a very high opinion.

And it is combined with the evaluation given by the independently completed paper.

Unexpectedly, this simple interview actually improved the old man's evaluation.

Old Mr. Qiu glanced at Zhang Shouwu, but he didn't explain what he meant by exceeding expectations.

After a pause, Mr. Qiu said, "Will you present the awards with me at tomorrow's dinner?"

Zhang Shouwu was taken aback for a moment, then nodded with a smile.

The other judges who heard this were shocked at first, and then they became more thoughtful.
