Chapter 131 Good Exam
Chen Zhou took out his Mi 3 mobile phone, connected to the network of Yanda Library, and began to search for documents.

I have to say that the performance of Mi 3 is not bad, that is, the screen is a bit small, which is not very convenient.

Chen Zhou found two important references.

[Sudbery, A. Quaternionic analysis: Bibcode, 1979]

[Brackx, F.; Delanghe, R.; Sommen, F. Clifford analysis: Longman, 1982]

The first literature is on quaternion analysis, which is the starting point for much research in Clifford analysis.

In the subsequent studies of Clifford analysis, many conclusions are similar to the conclusions of this literature.

The second is the pioneering work of Clifford's analytical research direction.

Chen Zhou took a notebook and wrote down the index numbers of these two documents, and took his computer with him at night to download them in the library.

It can only be said that rice 3 can be used, but it is really not convenient.

After reading the literature for a while, Chen Zhou felt a little uncomfortable. The literature in English was still uncomfortable.

For academic research, first-hand information is the most important, and the content after translation is always not enough.

Thinking like this, Chen Zhou secretly decided that he still needs to learn English in the future, at least there should be no obstacles when reading English literature.

He also roughly guessed why there is a component module of linguistics in the system. Language and writing are the concrete expression of thinking and the most important carrier of human civilization.

With language and writing, human knowledge can be communicated, thinking can collide, human knowledge can be recorded, and can be widely spread in space and time.

Withdrawing his thoughts, Chen Zhou marked the parts he didn't understand first, and continued reading after stumbling.

After a while, Chen Zhou felt his arm being poked, and he habitually looked at Yang Yiyi beside him.

Yang Yiyi pointed in You Yurou's direction, Chen Zhou looked over, and You Yurou had already packed her things and was about to leave the library.

"You said please eat." Yang Yiyi looked at Chen Zhou and said.

Chen Zhou smiled and rubbed her head: "Let's go."

The two packed up their things and walked towards the door of the library.

After leaving the library, Chen Zhou noticed that You Yurou seemed to be waiting for him and Yang Yiyi on purpose.

Yang Yiyi walked to You Yurou's side: "Come on, Yurou, someone invites you to dinner."

You Yurou hurriedly said to Yang Yiyi: "Then I won't be polite."

Looking at the appearance of Yang Yiyi and the two of them, Chen Zhou felt that he had been tricked?

Naturally, it is impossible to really eat rice bowls for dinner.

The three of them left the gate of Yan University and went to the snack street.

Yang Yiyi is a foodie, which Chen Zhou experienced in Luzhou Pedestrian Street.

But this petite You Yurou, he didn't expect that he was also a foodie.

After Yang Yiyi handed the backpack to Chen Zhou, she also took the little sister's backpack to Chen Zhou.

You Yurou showed an apologetic expression, and was dragged by Yang Yiyi into the snack street.

I saw two girls walking in front, stopping to eat and eat, while Chen Zhou was slowly following behind with three backpacks hanging on him.

However, Yang Yiyi didn't forget about Chen Zhou, she stopped from time to time to feed Chen Zhou.

Chen Zhou was also so happy, he had already sent a red envelope to Yang Yiyi, let's treat it as a treat.

It also saves him from worrying about what to eat.

When the two girls were full, Chen Zhou was almost full.

Thinking of the fact that he was going to check the literature at night, Chen Zhou proposed to go back to school.

Although Yang Yiyi and You Yurou were a little bit unsure, they didn't object, and the three of them returned to Yanda by the same route.

You Yurou said hello, and she didn't plan to make light bulbs anymore, so she separated from Chen Zhou and walked straight to the library.

Chen Zhou and Yang Yiyi walked hand in hand on the Yanda campus.

After that, Chen Zhou went back to the dormitory and brought out the computer, and the two went to the library.

The library was already overcrowded, the two searched for a while, and finally found two vacant seats.

Yang Yiyi took out linear algebra and started to read the book.

Yang Yiyi is not like Chen Zhou, although she is absolutely sure about the line agent test, she is still going to study for it.

At least, in terms of her attitude towards the exam, she was much more correct than Chen Zhou.

Moreover, when it comes to the exam, Yang Yiyi feels that it is true that one exam is missing and one is missing. She likes the feeling of testing her learning results.

Chen Zhou naturally didn't know what Yang Yiyi was thinking. If he knew, maybe he would correct his attitude towards the exam.

As he said in an interview many years later, he missed the time in Maochang High School very much.

Now Chen Zhou is full of thoughts about the documents he didn't finish reading this afternoon.

After taking out the computer, turning it on and connecting to the Internet, Chen Zhou found the two documents according to the index number recorded in the afternoon, and started to download them.

For one night, Chen Zhou was gnawing at these two documents.

No, it is one.

The depth of the content recorded in this thing made it a bit difficult for him to chew on it.

But at any rate, it can still be chewed on. Although there are a little more places marked, it will not turn the brain into a mess.

The library was closed at night, and Chen Zhou, who returned to the dormitory, sat down at the desk again and began to digest the knowledge he had learned.

It wasn't until Yang Yiyi sent a message reminding him to go to bed early that Chen Zhou got up to wash up.

Lying on the bed, Chen Zhou looked at the ceiling above his head, a little lost in thought.

Although [the properties of holomorphic functions and related operators in Clifford analysis], he has been thinking about it for a while.

But until today, he really decided to take this issue as his first research topic.

However, judging from the discussion with Wu Xiping and his own reading of literature, this topic is indeed a bit difficult for him now.

It involves the Stokes formula in complex Clifford analysis, the base elements of non-commutative Clifford algebras and the complex differential form of complex coordinates, and how to use this differential form to construct the Cauchy integral kernel in complex Clifford analysis. For him, It's all hard.

"Hey, let's take it step by step..."

Sighing lightly, Chen Zhou stopped thinking about it and turned over. His eyes could not help but fall on the pile of textbooks that he hadn't finished reading.

With a thump in his heart, Chen Zhou realized the crux of the problem, his foundation was still not solid enough.

Normally, he should finish reading all these textbooks before starting this subject.

After all, this topic is beyond his current knowledge and ability. Only by filling this ability gap can he carry out research on the topic smoothly.

After thinking about it, Chen Zhou made a decision to speed up the study of the remaining textbooks while researching the subject.

"Brother Chen, why are you sighing? Didn't you pass the geometry test today?" Zhao Qiqi's voice interrupted Chen Zhou's thoughts.

"What are you thinking? I think letting Chen Zhou fail the exam is harder than finding a girlfriend!" Zhu Mingli said.

"What's the matter with you, don't you have a girlfriend? You still blame me!" Zhao Qiqi said again, "Besides, don't I care about Brother Chen?"

Zhu Mingli said: "Chen Zhou has a girlfriend to care about, so I don't need you."

Zhao Qiqi stopped talking.

Chen Zhou said with a smile: "I remember the friendship, you two don't worry. Well, how did you do in the exam?"

Zhu Mingli: "It's okay, except for the score."

Zhao Qiqi: "It's not bad, it's really difficult to count points."

Li Li also said: "It's okay. How about you, Chen Zhou?"

Chen Zhou: "You did well in the exam."
