Volume 1: Student Life Chapter 131: Good Test
Chen Zhou took out his Mi 3 mobile phone, connected to the network of Yanda Library, and began to search for literature.
I have to say that the performance of Mi 3 is okay, but 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 paper is about quaternion analysis, which is the starting point for many studies in Clifford analysis.
In subsequent Clifford analysis studies, many of the conclusions were similar to those in this paper.
The second is the pioneering work in the research direction of Clifford analysis.
Chen Zhou took note of the index numbers of the two documents and would bring his computer to the library to download them in the evening.
I can only say that Mi 3 is possible, but it is really not very convenient.
After reading the literature for a while, Chen Zhou said he felt a little uncomfortable. It was not very comfortable to read the literature written entirely in English.
For academic research, first-hand information is the most important. After translation, the content is always not authentic enough.
Thinking this way, Chen Zhou secretly decided that he would continue to study English in the future, at least so that he would not have any obstacles when reading English literature.
He also roughly guessed why there was a linguistics module in the system. Language and writing are the concrete expression of thinking and the most important carrier of human civilization.
Only with language and writing can human knowledge be communicated, thoughts can collide, and human knowledge can be recorded and widely spread in space and time.
Chen Zhou collected his thoughts, marked the parts he didn't understand, and continued reading haltingly.
After a while, Chen Zhou felt his arm being poked, and he habitually looked at Yang Yiyi beside him.
Yang Yiyi pointed in the direction of You Yurou. Chen Zhou looked over and saw that You Yurou had already packed her things and was ready to leave the library.
"You said you would treat me to a meal." Yang Yiyi said to Chen Zhou.
Chen Zhou smiled and rubbed her head: "Let's go."
The two packed up their things and walked towards the library entrance.
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 is here to treat us to a meal."
You Yurou said to Yang Yiyi mischievously: "Then I won't be polite."
Looking at the appearance of Yang Yiyi and the other person, Chen Zhou felt like he was being tricked.
Of course it is impossible to have rice with toppings for dinner.
The three of them left the gate of Yan University and went to the snack street.
Yang Yiyi is a foodie, and Chen Zhou experienced that on Luzhou Pedestrian Street.
But he didn't expect that this petite-looking You Yurou was actually a foodie.
After Yang Yiyi handed the backpack to Chen Zhou, she also gave her sister's backpack to Chen Zhou.
You Yurou showed an apologetic expression, and was then dragged by Yang Yiyi into the snack street.
I saw two girls in front, walking, stopping and eating, while Chen Zhou, carrying three backpacks, followed slowly behind.
However, Yang Yiyi did not forget Chen Zhou. She would stop from time to time to feed Chen Zhou.
Chen Zhou was quite happy about this. He had already sent Yang Yiyi a red envelope, which he considered as a treat.
It also saves him from worrying about what to eat.
By the time the two girls had eaten and drunk their fill, Chen Zhou was almost full too.
Remembering that he had to look up some literature in the evening, Chen Zhou suggested going back to school.
Although Yang Yiyi and You Yurou were still a little reluctant, they did not object, and the three of them returned to Yanda along the same route.
You Yurou greeted them and decided not to be a light bulb anymore. She separated from Chen Zhou and walked straight towards the library.
Chen Zhou and Yang Yiyi walked hand in hand on the Yanda 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 crowded, and the two searched for a while before finally finding two empty seats.
Yang Yiyi took out the linear algebra book and started to study.
Yang Yiyi is not like Chen Zhou. Although she is absolutely confident about the linear algebra exam, she still prepares to review it.
At least, in terms of attitude towards exams, her attitude is much more serious than Chen Zhou's.
Moreover, when it comes to exams, Yang Yiyi feels that one less subject to take is one less subject to take. She really likes the feeling of testing her learning outcomes.
Chen Zhou naturally didn’t know what Yang Yiyi was thinking. If he knew, perhaps he would correct his attitude towards the exam.
As he said in an interview many years later, he missed his time at Maochang High School very much.
Now Chen Zhou's mind is full of the documents he didn't finish reading in the afternoon.
After taking out his computer, turning it on and connecting to the Internet, Chen Zhou found the two documents according to the index numbers he had recorded in the afternoon and began downloading them.
Chen Zhou spent the whole night studying these two documents.
No, it's one.
The depth of the content recorded in this thing made it difficult for him to read through it.
But at least I can still read it. Although there are too many markings, it won't turn my brain into a mess.
The library closed at night, and Chen Zhou returned to the dormitory, sat down at the desk again, and began to digest the knowledge he had learned.
It was not until Yang Yiyi sent him 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 absent-minded.
Although he had been thinking about the problem of [properties of holomorphic functions and related operators in Clifford analysis] for some time.
But it was not until today that he actually decided to make this issue his first research topic.
However, from his discussions with Wu Xiping and his own reading of literature, this topic is indeed a bit difficult for him now.
The Stokes formula in complex Clifford analysis, the basis elements of non-commutative Clifford algebras and the complex differential forms of complex coordinates, as well as how to use these differential forms to construct the Cauchy integral kernel in complex Clifford analysis were all difficult for him.
"Well, let's take it one step at a time..."
Chen Zhou sighed softly, thought no more, turned over, and his eyes fell on the pile of textbooks that he had not finished reading.
With a jolt in his heart, Chen Zhou realized the crux of the problem: his foundation was still not solid enough.
Normally, he should finish reading all the textbooks before starting this project.
After all, this topic is beyond his current knowledge and ability . Only by filling this gap in ability can he carry out the research project smoothly.
After thinking about it, Chen Zhou made a decision to speed up the study of the remaining textbooks while conducting research on the project.
"Brother Chen, why are you sighing? Didn't you do well in the geometry exam today?" Zhao Qiqi's voice interrupted Chen Zhou's thoughts.
"What are you thinking about? I think making Chen Zhou fail the exam is harder than for you to find a girlfriend!" Zhu Mingli said.
"What's wrong with you? Don't you have a girlfriend too? And you're still blaming me!" Zhao Qiqi said again, "Besides, I'm just concerned about Brother Chen, right?"
Zhu Mingli said: "Chen Zhou has a girlfriend who cares about him, so he doesn't need you."
Zhao Qiqi stopped talking.
Chen Zhou smiled and said, "I'm remembering the social gathering, don't worry. Well, how did you do in the exam?"
Zhu Mingli: "It's OK, except for the points."
Zhao Qiqi: "It's OK, but counting the points is a bit difficult."
Li Li also said: "It's OK. How about you, Chen Zhou?"
Chen Zhou: "I did well in the exam."
