Xueba starts with change

Chapter 94

Unconsciously, Chen Zhou has turned to the last content of Chapter 1 of "Concise Tutorial on Complex Variable Functions".

".The above concept of continuity and derivability on C generalizes to the extended complex plane."

After reading the last paragraph, Chen Zhou remembered the names of Riemann sphere and differential manifold.

Listening to it is quite tall, and learning to be even taller
After taking the scratch paper, Chen Zhou went through the key points of Chapter 1 again according to what he had recorded.

Then, Chen Zhou started to prepare to solve the exercise 1 after Chapter [-].

At this time, Yang Yiyi touched him lightly.

Chen Zhou turned his head and looked at her suspiciously, thinking that she had encountered some problem.

It turned out that Yang Yiyi raised her hand slightly and pointed.

Chen Zhou glanced in the direction Yang Yiyi pointed.

Two people, Professor Wu Xiping, who taught math scores, and Professor Zhang Zhongyuan, who taught Gao Dai.

Chen Zhou recognized Professor Wu Xiping at first sight, and he wanted to say hello.

But when he saw Professor Zhang Zhongyuan next to him, his instinctive reaction was a little embarrassed, and he wanted to pretend he didn't see it.

No matter what Chen Zhou thought, the two professors Wu Zhang saw him and were walking towards him.

Professor Wu Xiping has a good impression of this student, with strong self-learning ability and good study habits.

He remembered that in the first class, there were nearly 3 students from three departments, and Chen Zhou was the 12th-to-last answer.

By yesterday's numeracy class, Chen Zhou had already handed in the 12th positive answer.

The progress is very fast, and it is obvious that it is someone who has adapted to the Department of Mathematics of Yan University.

And Professor Zhang Zhongyuan's impression of Chen Zhou is very general, his high substitute class, Chen Zhou has nothing outstanding.

Even once asked a question, Chen Zhou didn't know the problem.

The two professors didn't come to Chen Zhou on purpose. Because they had a common topic, they made an appointment to meet and communicate in the seminar room of the library.

When the two professors passed by, Chen Zhou took the initiative to say hello and smiled at the two professors.

Wu Xiping also smiled at him and nodded lightly.

Zhang Zhongyuan just nodded.

After Chen Zhou said hello, he bowed his head and prepared to continue doing his own exercise one.

However, Chen Zhou found that Wu Xiping seemed to have stopped and stood behind him.

Without waiting for Chen Zhou to turn around, Wu Xiping patted him lightly and motioned for him to follow.

Chen Zhou got up, sorted out the information, talked to Yang Yiyi, and followed Wu Xiping to a small seminar room.

Wu Xiping asked directly: "Chen Zhou, why are you looking at the complex variable function?"

Chen Zhou was stunned for a moment, and then replied: "Looking at it, I saw this."

Wu Xiping didn't understand what Chen Zhou meant, and asked again, "What about your score? If I remember correctly, the complex variable function is a class that only starts in the second semester of the sophomore year?"

Chen Zhou: "I taught myself how to score in class."

Wu Xiping: "What do you mean? Have you finished all three volumes?"

Chen Zhou nodded slightly.

Wu Xiping looked at Chen Zhou in amazement. He remembered that after the first class and every subsequent class, the student seemed to be immersed in self-study, except for looking up at the last topic he wrote on the blackboard.

But this self-learning speed is too fast, right? !

Wu Xiping didn't speak for a while, not knowing what he was thinking.

Another professor in the room, Zhang Zhongyuan, said, "Chen Zhou, are you sure you have finished all three textbooks for grading?"

Chen Zhou thought about it and replied: "Because I have been studying by myself since the summer vacation, and Professor Wu's class also encourages students to study by themselves, so I studied mathematics in three volumes in one go."

Zhang Zhongyuan asked again: "Then why did you start looking at complex functions? According to your courses, you have already learned all the geometry you need to study in your freshman year? Also, have you learned all of my advanced substitute courses?"

"Cough cough." Chen Zhou coughed a few times, and then said, "Professor Zhang, I'm learning, I'm learning, but your senior generation is more difficult, so I'll learn more slowly."

"Is it difficult? Then I haven't seen you come to ask me?" Zhang Zhongyuan looked at Chen Zhou and said.

"Hey, old Zhang, Chen Zhou must have his own study plan. He is one of the few students I have met who has good study habits." Chen Zhou thought that Wu Xiping was speaking for him, but Wu Xiping said again , "Maybe Gao Dai is really not as interesting as my score, so he put it in the back, hahaha."

Zhang Zhongyuan glared at Wu Xiping, who was smiling, but the latter laughed even louder.

The two professors have a very good relationship, and they often joke with each other about the students' learning. You criticize me for not teaching well, and I criticize you for teaching boring.

But often Zhang Zhongyuan has the upper hand, because the math class is relatively more difficult than the high substitute class.

Scores belong to the need to come up with their own, there are more proof questions, many of the high generation know the basic knowledge, and the later questions can be brought in.

All in all, the score is a little more flexible.

Therefore, many students will complain that it is difficult to score, and then throw themselves into the arms of the high generation.

But like Chen Zhou, who finished mathematics in one breath, and then went to learn complex variable functions, it happened that Gao Dai, who also belonged to the core basic course, was the first student who didn't read it.

Wu Xiping finally stopped laughing, and then looked at Chen Zhou: "You said that you have finished all three volumes of mathematics, then I will test you."

Chen Zhou asked, "Teacher, are there any rewards?"

Wu Xiping was stunned for a moment, then smiled and said, "Yes. Lao Zhang and I are working on a topic, applied research on the interpenetration and fusion of advanced algebra and mathematical analysis. Are you interested?"

When Zhang Zhongyuan heard this, he glanced at his old friend, but didn't say anything to stop it.

Chen Zhou immediately replied: "Please ask the teacher to ask the question."

Wu Xiping: "Tell me about the connection between several differential median theorems."

Chen Zhou thought he had heard it wrong, and asked Wu Xiping again, and indeed asked him to explain the connection between the differential median theorem.

This is embarrassing. Professor Wu sent the points, so I can only accept it.

Chen Zhou first started with the content and proof of each theorem of the differential median value theorem, and then explained the connection between each theorem in simple terms.

This is probably the content that Chen Zhou is most familiar with and has the deepest grasp of.

After listening to Chen Zhou's answer, Wu Xiping's eyes showed admiration, and this understanding has surpassed that of most students.

Wu Xiping: "Then you can talk about the Cauchy criterion."

The Cauchy Criterion is the content of the second book of numerology, and it appears twice, once in the content of the series of several items, and once in the content of the book function sequence.

Chen Zhou organized the language, and then said: "The Cauchy criterion is mainly used to judge the convergence of series."

After Chen Zhou finished speaking, Wu Xiping nodded and said, "It's alright, you can leave me your mailbox, and I'll send you the project materials when you come back. You can take a look first."

However, Chen Zhou asked, "Professor Wu, have you not asked about the contents of the third volume of the score?"

Wu Xiping: "No need, you can leave a mailbox and read the book by yourself."

Chen Zhou glanced at Wu Xiping, found a note paper and wrote down his mailbox, and was ready to leave.

At this time, Zhang Zhongyuan said: "Look back and read Gao Dai's course first, as well as abstract algebra."

"Uh ok" Chen Zhou replied repeatedly, and then left the seminar room.

In the seminar room, Wu Xiping asked, "Old Zhang, what do you think?"

Zhang Zhongyuan commented: "It is a solid learning and it is worth cultivating."

Wu Xiping laughed and joked: "Aren't you angry that he didn't learn from your high generation?"

Zhang Zhongyuan glanced at him and said nothing.

Wu Xiping said again: "His scores should be learned after school starts."
