From a university student to a chief academician

Chapter 144 Ye Fei's Student

Time flies like water, and it's April in a blink of an eye!

March and April are very special periods for universities across the country.

The postgraduate entrance examination is not a national unified examination, but each school independently decides the time and content of the re-examination.

From mid-March to mid-April, a random time.

Moreover, the time for the postgraduate entrance examination for each school is not fixed every year.

This year, the re-examination for the postgraduate entrance examination of Zhonghu University is at the beginning of April, April 4.

The re-examination for postgraduate entrance examination is divided into written examination and interview.

The morning of the first day is a written test, and the morning of the second day is an interview.

October 4, early morning!

Many students on campus are in a hurry, holding books or documents in their hands, reciting on the road.

Ye Fei finished his run, took a shower and changed clothes, and after breakfast, he walked slowly to the interview room with a thermos filled with hot water in his hand.

Ye Fei walked into one of the teaching buildings. He was going to interview candidates today.

In fact, the interview process does not necessarily require a tutor to interview.

But Ye Fei needs to select the students he is satisfied with, so he has to go to the interview in person.

There are many candidates standing at the entrance of the teaching building, busy reciting things.

When Ye Fei walked into the classroom, there were already four teachers inside.

Ye Fei greeted them with a smile.

After sitting down, Ye Fei said to the person sitting beside him: "Dean, why are you here?"

The dean smiled and said: "I heard that your interview method today is very special, I want to see the excitement."

Ye Fei looked at the other three, Lu Yishan, Liu Yisheng and Zhou Kang.

They are all old acquaintances of Ye Fei, and Lu Yishan is Ye Fei's mentor.

Liu Yisheng is a good friend of Lu Yishan. He once taught Ye Fei when he was a graduate student.

Zhou Kang is a professor of the School of Computer Science. Ye Fei once cooperated with him in the computing power laboratory of Zhonghu University, and it was also there that Ye Fei created mathematical algorithms.

There are 46 examiners in the postgraduate entrance examination interview, and there are three to four examiners in each interview site.

Lu Yishan said: "I heard that there are 150 students who want to choose you as a tutor this year. You can't possibly interview every one of them. It will take a long time."

Each interview is usually 10 minutes, and 150 people are all interviewed, at least [-] hours.

And the interview must be completed today, so it is impossible to interview all 150 people.

Ye Fei shook his head and said: "Of course not. My interview process is also divided into written test and interview. The written test is very short, half an hour. A small part is selected from the written test, and the interview is conducted from this small part."

Ye Fei looked at the dean and asked, "Dean, my method will work!"

There are rules and regulations for the postgraduate entrance examination, whether it is the initial test or the interview, and few teachers will not follow the rules.

The dean smiled and said, "Do whatever you want!"

The postgraduate entrance examination is not a national unified examination. To put it bluntly, it is up to each school to decide how to take the test and what to test.

Of course, there are usually three written tests for the initial test, one written test for the second test and an interview.

All schools follow this approach with little variation.

Unless there are special circumstances.

For example, those with special requirements like Ye Fei.

"What about candidates who fail the written test?" Liu Yisheng asked.

"Candidates who fail the written test will be distributed to the rest of the teachers, who will continue the interview."

Liu Yisheng said, "Have you talked to the other teachers about this?"

Ye Fei said: "I have already said hello, and they said yes."

All the interviewers have a group, and Ye Fei is also in it, he has already greeted them a few days ago.

At this time, some students in front of the teaching building were discussing with each other.

Lin Yi and Wang Yuan were also among them, and they were sitting together by the flower bed.

They didn't know each other, they just sat together.

Lin Yidao: "Student, which exam room are you from?"

Wang Yuan said, "Exam room 201, what about you?"

Lin Yi said in astonishment: "Are you also choosing Professor Ye?"

Before the re-examination, the school sent a message to all candidates who chose the Department of Mathematics to collect who chose Professor Ye as their tutor.

After that, all students who choose Professor Ye as their tutor will be distributed in several classrooms and wait.

Therefore, students in examination room 201 must choose Professor Ye as their tutor.

The postgraduate entrance examination process is that first enter the classroom and wait, then draw lots to determine the interview order, and then go in for the interview.

Of course, this is the general process, and Ye Fei's interview today will be different.

Wang Yuan said, "You too?"

"Yes!"

In an instant, the eyes of the two were different.

This is a competitor!
Professor Ye can recruit up to three students, but this year, 150 people chose Professor Ye as their tutors.

Alexander!

Lin Yi said: "What questions do you think Professor Ye will ask us soon?"

Wang Yuan said: "It should be similar to the previous process. The whole process will be communicated in English, and some random questions will be asked."

The interview in the postgraduate entrance examination re-examination, according to the general process, is answered in English throughout the whole process, and the tutor will randomly ask some questions.

Of course, some schools do not need to use English all the time, it depends on the school's regulations and the arrangement of the instructor.

Don't ask why you speak English, because English is an international language.

Most of the documents in the world are written in English, and all international conferences are also communicated in English.

If you are not good at English, it is almost impossible to do well academically.

Unless you are a prophet, you are born with a lot of academic knowledge in your head.

If not, if you want to develop in academia, you must be good at English.

Of course, students who can pass the exam will not be bad at English.

Lin Yi nodded, agreeing with Wang Yuan's statement.

Lin Yi asked: "Professor Ye said he valued talent, what do you think about talent?"

Wang Yuan shook his head and said: "Who knows, maybe Professor Ye has some special method, we just need to review the algebra for undergraduate level, and we don't need to worry about the rest, even if we worry about it, it's useless."

"This is Professor Ye interviewing us, not us interviewing Professor Ye."

Lin Yi nodded: "That's true."

He asked cautiously again: "How sure are you?"

Wang Yuan said: "It's hard to say, I have prepared everything that should be prepared, how about you?"

Lin Yidao: "I should be more prepared than you. I have personally asked Professor Ye what preparations I need to make."

Wang Yuan: "???"

Obviously I was the one who asked. At that time, none of the postgraduate entrance examination students asked. It was I who sent the message to the group after asking.

Wang Yuan said, "What's the name of your ID in the group?"

"What's your ID?" Lin Yi said, "You tell me first."

"Little white dragon in the waves!"

Lin Yi's eyes widened in surprise, and said, "The little white dragon in the waves is you?"

Wang Yuan asked calmly, "What's the matter? Is there any problem?"

Lin Yi said: "I'm crazy like a summer head!"

"It's you when you're summer crazy." Wang Yuan said pleasantly, "We two often interact in the group!"

Lin Yi laughed and said, "Yeah, what a coincidence, the two of us interact the most in the group, and now we are sitting together again without knowing who the other party is."

Wang Yuan said: "Since you are crazy about summer, it is not you who asked Professor Ye, it was obviously me who asked."

Lin Yidao: "I asked about it a year ago, and I asked about it a year earlier than you, so I prepared for the re-examination a year ago."

Wang Yuan: "..."

Wang Yuan's mentality exploded a bit.

Lin Yi was preparing for the re-examination a year ago. Doesn't that mean that Lin Yi has a good chance of passing it.

One of the three is removed, leaving only two.

If Professor Ye only accepts two graduate students, then one of the two will be removed, leaving only one.

As far as Wang Yuan knows, there are 150 people who chose Professor Ye as their mentor.

2:151, or 1:151.

Wang Yuan instantly felt that the pressure in his heart was like a mountain, very heavy.

Lin Yi laughed heartily. He asked Ye Fei at that time, but he didn't get any information. He just asked him to go back and review.

Therefore, his start is the same as the rest of the candidates.

However, the interview not only tests the candidate's ability, but also tests the candidate's mentality.

If a candidate appears flustered during an interview, mistakes are likely to be made.

Lin Yixin said: "By blowing up the mentality of one of the opponents, my interview pass rate will be higher."

At this time, a voice sounded on the radio, saying: "All candidates, please enter!"

All the students in front of the teaching building clattered into the teaching building, and went to wait in the classroom according to their admission tickets.

The postgraduate entrance examination process is to wait in the waiting room first, then draw lots, and go to the interview according to the lottery number.

Of course, this is the general process, and it is different with Ye Fei.

Shortly after all the students entered the classroom and sat down, they saw a female teaching assistant walking in with a paper in her hand.

"Huh?" All the students were puzzled: "Why are you holding the test paper and not drawing lots?"

The female teaching assistant came in and said, "Everyone, please distribute the papers."

After all the students got their papers, the female teaching assistant said, "Everyone, please finish writing the papers within half an hour."

All the candidates looked down at the paper. There was only one question on the paper.

"One question for half an hour?" Many students were surprised: "Who do you look down on? I can usually write half a paper in half an hour."

After they continued to read, everyone was stunned.

What is this and what, no!
[For a given m, n∈Z≥0, let T be a set...]

The female teaching assistant looked at the students present and sighed in her heart: "I heard that there are 150 students who chose Professor Ye. This may be the tutor chosen by the most students in all universities in history."

"I don't know if there will be no one to come after, but there must be someone who has never come before."

"Professor Ye can get this kind of treatment, but other teachers don't have this kind of treatment."

Half an hour passed quickly, and some students didn't even write down a word. Although most students couldn't think of a solution to the problem, they wrote blindly.

It's really too difficult. I know every word and even know each word together, but I can't answer it.

There is at least one psychological comfort for writing but not handing in a blank paper.

And those students who didn't start writing, gave up completely.

It was so hard to lie flat.

The female teaching assistant said: "All candidates, please put down their pens and collect the papers now."

All the students put down their pens exhaustedly, this question was more tiring than they did the whole paper.

Usually when doing papers, although you may encounter problems, at least most of the content on the papers can be written.

But today there was only one question, and they racked their brains but couldn't come up with a solution.

If you don’t know this question, it means you won’t know the whole paper.

This is very painful.

After the female teaching assistant collected the papers, she said, "All candidates please wait here."

After finishing speaking, she took the paper into another classroom and handed it to Ye Fei.

Ye Fei had already received 150 papers at this time, and he distributed the papers to a few people around him, saying: "You also help me to screen and pick out the papers that have written content."

"Okay!" Several people said.

In the end, more than 110 papers were picked out, and only more than 30 papers were blank.

After Ye Fei got the test paper, he read more than a dozen in a row. He read it very quickly, and he could tell whether the written content was correct after a few glances.

Unfortunately, among the dozen or so papers, none of them gave the correct answer.

Ye Fei had thought about this situation a long time ago. He also came from his student days.

If you don't know how to write papers, just write blindly.

Anyway, as long as it is written, it is not a blank paper, at least I feel a little psychologically comforted.

150 two papers, read it in half an hour.

Ye Fei wrote down the names of ten of them in the paper.

150 two papers, only these ten people wrote correctly.

Ye Fei gave the names of these ten people to the female teaching assistant, and said, "Call these ten people in order one by one, and the rest can be arranged to go to other teachers for interviews."

"Okay, Professor Ye!"

After the female teaching assistant finished speaking, she went out and called the candidates in one by one.

"Ma Lintu, please follow me!"

A candidate walked in and was taken aback when he saw the teacher present.

Why is the dean here?

Professor Lu Yishan?Isn't this Professor Ye's tutor?

Professor Liu Yisheng?This is also a full professor of the School of Mathematics!

Isn't Professor Zhou Kang from the School of Computer Science?
What does he do for the postgraduate entrance examination for mathematics majors?
Ye Fei smiled and said, "This candidate, please sit down!"

Ma Lintu quickly bowed and said, "Hello, teachers, my name is Ma Lintu."

After speaking, he sat down.

Ye Fei said: "This candidate, please introduce yourself briefly in English."

"OK!" Ma Lintu said, "My name is Ma Lintu..."

He quickly introduced himself briefly in English.

Ye Fei said in English: "The algebraic integral ring of the known number field K..."

"Please give a simple explanation and solution to this problem."

While Ye Fei was talking, Ma Lintu recorded what Ye Fei said with pen and paper.

After Ye Fei finished speaking, Ma Lintu looked at the recorded question, thought for a moment, and then said in English: "This is a question on Diophantus. In this case..."

After Ma Lintu finished speaking, Ye Fei said, "It's ok, your answer is over, you can go out."

There was a trace of panic on Ma Lintu's face, only one question?Does that mean I failed the interview?

Ye Fei smiled and said, "Don't be nervous, I only ask one question for all candidates."

The panic on Ma Lintu's face dissipated in an instant. It turned out that it was not a failure, but Professor Ye's interview method.

Ma Lintu stood up and bowed: "Goodbye, teachers!"

After Ma Lintu went out, Professor Zhou Kang said: "You just ask one question? Don't ask a few more? I think his answer is pretty good!"

By convention, the examiner will ask several questions.

Ye Fei said: "One question is enough. I can already see the talent of this candidate in mathematics. What I need is quality, not quantity. It is useless to ask more questions."

The dean asked: "Then how is this candidate's talent in mathematics?"

"It's not bad!" Ye Fei said: "If you develop well, you can still do something on the road of mathematics."

The dean nodded, took out his mobile phone, and recorded Ma Lintu's name.

Since Ye Fei said that there is something to be done, then he can focus on it, maybe he can cultivate an excellent talent for the school.

Afterwards, Ye Fei interviewed five candidates, all of whom had good abilities and had a certain talent in mathematics.

But there is still some distance from Ye Fei's psychological standard.

Ye Fei also knows that the candidates who can come to Zhonghu University for the postgraduate entrance examination are not very outstanding in terms of the national postgraduate entrance examination students.

Those who are excellent will not come to Zhonghu University.

Therefore, Ye Fei did not set too high a psychological standard for candidates.

As long as you can understand your own literature and learn it in a short time, then you will meet the standard.

If you can't even meet this standard, Ye Fei won't accept it.

Even if one of the ten candidates fails to meet the standard today, Ye Feihui will not accept any of them.

Ye Feixin said: "I hope we can meet, otherwise the dean will not be able to explain it here."

At this time, a simple and honest young man with a square face walked in. He was tall and strong, and looked very honest.

Ye Fei saw a smile on the student's face, he knew this student.

It was Lin Yi who came to his office more than a year ago to inquire about his postgraduate entrance examination information.

"Hello teachers, my name is Lin Yi."

Ye Fei smiled and said, "This candidate, please sit down!"

After Lin Yi sat down, Ye Fei said, "Please give a brief self-introduction in English."

After Lin Yi finished introducing himself, Ye Fei said, "Assume K is a number field, and the elliptic curve E/K satisfies Gal(K(e[2]/K))..."

"Please give a simple explanation and solution to this problem."

Lin Yi recorded what Ye Fei said with a pen and paper, and after thinking for a moment, he said: "Suwei is real Suwei and..."

After hearing Lin Yi's words, Ye Fei's eyes lit up, he nodded slightly, and said in his heart: "To be able to answer this question, he has a good talent in mathematics, very good, he is one of them."

"Finally found one, I hope there will be another one, so my mission will be completed."

Ye Fei's interviews are very fast. Generally, an interview with an examiner takes about 10 minutes, but with Ye Fei, an interview is completed in about 10 minutes.

After nearly two hours, the interview ended.

The dean asked: "Ye Fei, how are you doing? Which ones do you choose?"

Ye Fei said: "Let's choose Lin Yi and Wang Yuan, these two students!"

Strange to say, both of these two students had come to look for Ye Fei.

But Ye Fei definitely didn't choose them because they had found him before.

Rather, these two are the best of the ten, and their math talent is the strongest.

"Only two?" The dean asked suspiciously, "I think the rest of the students are pretty good too!"

Ye Fei shook his head and said: "The rest of them are not good, their talents are not so good. These two students are the best among the ten students, which just meet my requirements for talents."

"You also know that mathematics is the most test of talent among all subjects."

"If it is a student with less talent, they may not understand a lot of my research, let alone do research with me."

Everyone nodded, that's the truth.

In the postgraduate entrance examination, students choose tutors, and tutors also choose students.

For students who are not capable enough, students cannot do a lot of research done by their tutors.

If so, why choose them.

The dean said: "Are the other eight people's mathematical talents good?"

Ye Fei nodded and said, "Yes, the other eight people are all talented."

The dean said: "Then I will arrange them for the rest of the mentors."
