Chen Zhou took out his Rice 3 mobile phone, connected it to the Yanda Library's network, and began to search for documents.

I have to say that the performance of Rice 3 is OK, which means that the screen is a little smaller and 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 about quaternion analysis, which is the starting point for research in many Clifford analysis.

In the subsequent Clifford analysis, many conclusions were similar to the conclusions of this document.

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

Chen Zhou took the notes to record the index numbers of these two documents, and took the computer with him to the library to download it.

I can only say that rice 3 is OK, but it is really not very convenient.

After reading the documents for a while, Chen Zhou said that he felt a little uncomfortable. The documents in all English still felt uncomfortable.

For academic research, first-hand information is the most important thing. After translation, the content is still not tasted enough.

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

He also roughly guessed why there is a module of linguistics in the system. Language and characters are the specific 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 widely disseminated in space and time.

Retracting his thoughts, Chen Zhou marked the things he didn't understand first and continued to read them stumblely.

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

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

"You said you were invited to dinner." 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 and said, "Let's go Yurou, someone will invite her to dinner."

You Yurou said to Yang Yiyi with a slight slight silence, "Then I'm not polite."

Looking at Yang Yiyi and the others' appearances, Chen Zhou felt that he had been tricked?

Of course, it is impossible to really eat rice with drizzle for dinner.

The three of them left Yan University’s campus and went to Snack Street.

Yang Yiyi has the attributes of foodie, and Chen Zhou experienced it in Luzhou Pedestrian Street.

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

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

You Yurou showed a hint of apology, and was immediately pulled into the snack street by Yang Yiyi.

I saw two girls walking and eating in front, while Chen Zhou was hanging three backpacks and slowly following behind.

However, Yang Yiyi did not forget Chen Zhou, and stopped from time to time to feed Chen Zhou.

Chen Zhou was so happy that he had already sent Yang Yiyi a red envelope and just treated it as a treat.

It also saves him from worrying about what to eat.

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

Thinking of the fact that he was preparing to search for documents at night, Chen Zhou proposed to go back to school.

Although Yang Yiyi and You Yurou were still unsatisfied, they did not object, so the three of them returned to Yanda the same route.

You Yurou greeted her and didn't plan to make a light bulb anymore. She separated from Chen Zhou and walked straight towards the library.

Chen Zhou and Yang Yiyi held hands and took a walk on the Yan University campus.

Afterwards, Chen Zhou went back to the dormitory and took out the computer, and the two went to the library again.

The library was already overcrowded. The two searched for a while and finally found two empty seats.

Yang Yiyi took out linear algebra and started reading books.

Yang Yiyi is not like Chen Zhou. Although she is absolutely sure about the exams of the line generation, she is still preparing to review them.

At least, she is much more upright than Chen Zhou in her attitude towards exams.

Moreover, when it comes to exams, Yang Yiyi feels that she really misses one subject. She likes this feeling of testing 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.

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

Now Chen Zhou is thinking about the documents he hasn't finished reading in the afternoon.

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

Chen Zhou was judging these two documents all night long.

No, it's one.

It was a bit difficult for him to chew the depth of the content recorded by this thing.

But at least, I can still chew on it. Although there are a little more marked areas, it will not turn the brain into a ball of paste.

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

It was not until Yang Yiyi's news came, 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, feeling a little stunning.

Although he has been thinking about this issue for a while.

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

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

The Stokes formula in the complex Clifford analysis involved, the basis elements of the non-exchangeable Clifford algebra and the complex differential form of complex coordinates, and how to use this differential form to construct the Cauchy integral core in the complex Clifford analysis, is difficult for him.

"Oh, let's do it step by step..."

After sighing softly, Chen Zhou stopped thinking about it, turned over, and his eyes couldn't help but fall on the stack of textbooks that he had not finished reading.

My heart skipped a beat. Chen Zhou realized the key to the problem, but his foundation was still not solid enough.

Normally, he should finish all these textbooks before starting to work on this topic.

After all, this topic is beyond his current knowledge and ability range. Only by filling this gap in ability can he conduct 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 project.

"Brother Chen, why are you sighing? Didn't you do well in geometry today?" Zhao Qiqi's voice interrupted Chen Zhou's thoughts.

"What are you thinking? I think it's harder to get Chen Zhou to fail the exam than to find a girlfriend!" Zhu Mingli said.

"What's wrong with you? Don't you have no girlfriend? You're talking about me!" Zhao Qiqi said again, "Besides, don't I care about Brother Chen?"

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

Zhao Qiqi stopped talking.

Chen Zhou smiled and said, "I remember the friendship, don't worry. Well, how are you doing in the exam?"

Zhu Mingli: "It's okay, except for the number of points."

Zhao Qiqi: "It's OK, it's really difficult to count points."

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