Halfway through December, Zhang Zhongyuan's project was completed on time according to the plan.

In addition, Chen Zhou also revised and improved all the work he was responsible for according to the relevant errors recorded in the wrong question set.

So much so that after Zhang Zhongyuan saw it, he was amazed in his heart.

The rigor of the calculations, the rationality of the logic, is hard to believe was the work of a freshman.

He discussed with Chen Zhou without hesitation: "Or will the writing of the paper be handed over to you?"

Chen Zhou politely rejected Zhang Zhongyuan's proposal.

If he writes a paper, then most of his daily time will be taken up by the paper, which Chen Zhou is unwilling.

After withdrawing from Zhang Zhongyuan's research group, Chen Zhou began his own plan.

Between the book and the subject, the cycle is not endless.

Clifford's analysis has been almost groped by him.

A tool that wants to use it well must be fully understood.

Starting from the research background and research status of Clifford analysis, Chen Zhou has a complete understanding of the past and present life of Clifford analysis.

There is also the Cauchy integral formula, which is one of the main formulas for single-complex analysis, multi-complex analysis, and real Clifford analysis, and serves as a powerful tool for studying the various properties of holopure functions.

After getting acquainted with Clifford's analysis, Chen Zhou began to find a way to find the Cauchy integral formula in Clifford's analysis.

These are all in the service of the whole subject.

It's just that Chen Zhou encountered difficulties at the beginning.

As Zhang Zhongyuan said, this topic is still beyond the scope of undergraduates.

It was also beyond the scope of Chen Zhou's knowledge, even if he had read so many books.

As for the solution, there is only one solution, and that is to enrich yourself.

If you don't have enough knowledge, then liver it!

The study of textbooks and Clifford's analysis are intertwined with the topic of Chen Zhou.

In class, Chen Zhou was brushing books, and after class, Chen Zhou was on the way to brush books.

Except for when he was with Yang Yiyi, Chen Zhou briefly broke away from the world of books.

The rest of the time, Chen Zhou only worked this one topic.

This process of working hard for one thing, working hard for an extremely difficult thing, if you don't get feedback, is actually very sad.

Because, if you don't get feedback for a long time, you will develop a sense of self-doubt, which will eventually lead to the collapse of confidence.

Fortunately, Chen Zhou doesn't need to worry about this problem, and the wrong question set is a good partner for his feedback.

Every idea, every formula, every knowledge point, he can get feedback from the wrong question set.

It is precisely this kind of pointing out the mistakes that enabled Chen Zhou to correct the direction in time and have enough energy to seize the inspiration of that moment.

Chen Zhou constructed a complex differential form containing non-commutable Clifford algebras and complex coordinates by constructing a complex differential form of Clifford algebras, and then constructed the Cauchy integral kernel in the complex Clifford analysis.

Then, through the Stokes formula in the complex Clifford analysis and the Stokes formula in the multiple complex variable functions, the Cauchy-Pompier formula in the complex Clifford analysis and the Cauchy integral formula of the right regular function are derived successively.

In this way, the problem of Cauchy integral formula was solved, which laid the foundation for the subsequent study of the various properties of holopure functions and the problem of partial differential equations in complex Clifford analysis.

After that, according to the definition of the T operator with Bocher-Martinelli kernel in the complex Clifford analysis, Chen Zhou also obtained the boundedness of the T operator in Lp space by using Herder's inequality.

It's just that the results that Chen Zhou has obtained now are still far from the solution of the entire problem......

December 25th.

Qiu Chengtong College Student Mathematics Competition, the official website registration entrance is officially opened.

Qiu Sai was initiated by the famous mathematician Mr. Qiu Lao, and was carried out among college students in colleges and universities in all regions of China.

From the five major directions of analysis and partial differential equations, geometry and topology, algebra and number theory, probability and statistics, and applied and computational mathematics, the mathematical knowledge, accomplishment and ability of college students are comprehensively tested.

Corresponding to the above five subject directions, the competition set up "Hua Award", "Chen Award", "Zhou Award", "Xu Award" and "Lin Award".

For the individual competition, there is no limit to the subjects that each person can register, and all five subjects can be registered.

In addition, in order to reward students with outstanding comprehensive ability, students who sign up for multiple subjects in individual competitions will be selected according to the best results in the competition, which is the "Qiu Award".

In addition to the individual competition, there is also a team competition, in which five people from the same school participate in a team, and each of them is responsible for a subject.

The first place in the team competition won the gold medal trophy.

Chen Zhou called Yang Yiyi together, plus Zhao Qiqi from the dormitory, and signed up for the individual and team competitions of Qiu Sai.

As for the subjects, Chen Zhou naturally enrolled in all five.

This time, he can collect these awards named after the great mathematicians of China.

The three brothers in the dormitory were naturally the same as Chen Zhou, and they reported all five subjects.

As a student of the Department of Mathematics of Yan University, how can you be afraid of mathematics competitions?

Yang Yiyi only reported two subjects: analysis and partial differential equations, and geometry and topology.

As for the team competition, she was responsible for the subject of Analysis and Partial Differential Equations.

Analysis and partial differential equations are widely used in physics, and Yang Yiyi's current freshman mechanics course has a great connection with partial differential equations.

This is also one of Yang Yiyi's most confident subjects.

After the registration, there are still nearly 4 months before the official start of the competition.

It's enough for each of them to prepare.

Counselor Huang Yemei also specially asked Chen Zhou whether they had signed up, who was the other person in the team, and so on.

In Chen Zhou's dormitory, when Huang Yemei knew that the fifth person in the team was Yang Yiyi, she glanced at Chen Zhou first, and then looked at Zhao Qiqi and the three of them with complicated eyes, thinking in her heart, didn't these three people pay attention to the campus network?

In addition, Huang Yemei also gave an answer to Chen Zhou's previous question.

It's okay to minor in physics, but you have to complete the undergraduate course in mathematics first.

Don't think about the situation of double majoring in the Department of Mathematics and the Department of Physics at the same time, this kind of student is not nothing, but in the last one or two decades, there is none.

As for how to complete the undergraduate course, Huang Yemei looked at Chen Zhou and smiled, giving a simple and crude method.

At the end of the freshman year, students take exams for each grade at the same time.

Speak with grades.

If you have excellent grades, you will naturally have no problems.

Otherwise, don't talk about it.

Huang Yemei said softly: "This condition is actually quite beneficial to you, how much have you read the textbooks you took from me?"

"I've seen more than half of it. Chen Zhou nodded back.

For him, it's not just the advantage, it's actually the easiest way to do it......

Moreover, the completion of the undergraduate course in the Department of Mathematics also means that he can graduate early.

All you need to do is complete your dissertation.

Chen Zhou, who was thinking like this, really heard Huang Yemei say: "If you want to graduate early, this condition is also a precondition, after completing the undergraduate course, you only need to complete the graduation thesis with a professor, and you can graduate early." ”

"As for the physics department, I don't know the specifics, but I guess it's about ......."
