Chapter 107 How did I become a scholar? (13)
"Probability theory and mathematical statistics? Applied stochastic processes? Stochastic process theory?"
Xu Qingshan listened with some interest on the phone as Professor Chen Dayue, who claimed to be the head of the Department of Probability and Statistics of the School of Mathematics at Peking University, spoke like a surging river.
"Professor Chen, I just happen to be studying by myself recently. If it's convenient for you, can you give me an overview of the process of undergraduate mathematics training at Peking University?"
Although it was listed in the materials Zhang Jincai gave Xu Qingshan, Xu Qingshan still wanted to listen directly to director-level professors like Peking University School of Mathematics.
"oh?"
Chen Dayue raised his head and glanced at Zhang Jincai, with a smile on his face.
"Well, let's do this. It's inconvenient for me to use Lao Zhang's cell phone to call you now. Besides, it's the number you dialed. The phone bill there is also expensive. So, I'll leave your contact information and I'll get back to you later. How about the office calling you back and then we keep in touch?”
Xu Qingshan naturally didn't know the situation at Zhang Jincai's side, so he agreed casually.
Chen Dayue raised his eyebrows at Zhang Jincai.
Zhang Jincai looked strange.
"Okay, stop being pretentious and show me Qingshan's paper again to see how his mathematical thinking is."
Chen Dayue confidently reached out to Zhang Jincai to ask for Xu Qingshan's paper.
"Don't be stingy. Every year during the admissions process, I'll leave you with my raw Pucha cakes. Look at the past two or three years, not many students from the School of Mathematics are willing to take the initiative to come to our Department of Probability and Statistics. It's all strange. you."
Chen Dayue muttered to ask for favors from Zhang Jincai.
Zhang Jincai was completely speechless.
"Here, here, take a look for yourself."
Zhang Jincai gave the information packet to Chen Dayue and rolled his eyes at him.
"You still blame me. Isn't that a problem with your probability statistics? It's hard to get academicians but not academicians, to be employed but not employed. It's hard to win awards and it's hard to write papers."
Zhang Jincai didn't know much about mathematics, but he was somewhat concerned about the situation in the Mathematics Institute.
"What's so hard about writing? Don't you think I'll just keep writing? After all, we're still developing, and we don't have as many people doing it like Complex Change. Besides, it's hard to find a job. In the Internet era in the future, our probability Statistics students are still very good at computers even if they don’t do academics.”
"Then why don't they just study computer science? Don't they want to?"
"I'm too lazy to pay attention to you. You're a philosophical guy who doesn't understand the beauty of our mathematics. I'm reading the paper."
Chen Dayue and Zhang Jincai quarreled for a while, and Chen Dayue read Xu Qingshan's paper seriously.
I even read his papers and interview records for other subjects.
The more he saw this, the happier he became. He would glance at Zhang Fuxi from time to time and nod approvingly.
Xiaozhang is a lucky star.
Until Chen Dayue excitedly got Xu Qingshan's contact information and ran back to his office with Zhang Fuxi.
Zhang Jincai was still standing by his desk, holding a tea cup in his hand and muttering with a strange expression.
"I've seen people who are eager to be wives for others, and I've seen people who are eager to give free guidance to others. This is the first time I've seen her today."
He drank some water and rinsed his mouth, but did not spit it out.
"Forget it, Lao Chen is pretty good anyway, let's use it first. Anyway, Lao Wen still has to find someone to help contact him."
Zhang Jincai is a teacher at Ma Yuan.
The most important thing in Ma Yuan was students, so he couldn't understand Chen Dayue's misery.
Every year, there are students from all walks of life and various subjects who want to be admitted to the Beijing University of Marathon.
As for why?
How about a change of clothes.
Xu Qingshan was actually a little confused.
Although Uncle Jincai did say that he would provide him with more resources so that Xu Qingshan could have a good understanding of various subjects before choosing his future direction.
But Xu Qingshan didn’t expect it to happen so soon.
He has not finished reading several textbooks on the progressive form of functions of complex variables in his hand.
It’s time for self-study class.
Xu Qingshan received a message from Chen Dayue and wanted to chat with him when he was free.
Xu Qingshan's attitude was respectful. This was the teacher who took the initiative to be prostituted for free.
"Hello, Director Chen."
"Hey, what do you call me when you're studying? Just call me teacher."
When Chen Dayue thought of Xu Qingshan's thinking and logic, he became elated, and his words were full of kindness.
"Okay, Teacher Chen."
Xu Qingshan did not stay in the classroom during his self-study class, so he sat on the playground with his mobile phone.
"As far as I can see from the training plan and curriculum given to me by Uncle Jincai, the basic subjects to be learned in the School of Mathematics are: mathematical analysis, advanced algebra, geometry, probability theory, functions of complex variables, functions of real variables, and ordinary variables. Differential equations and abstract algebra, right?"
Xu Qingshan has now taken the book on complex variable functions.
"Well, yes, these are pretty much the basic courses."
"Teacher, I'm currently learning functions of complex variables. Do you have any suggestions for my next course route or professional direction?"
"Hey, you've asked the right person."
When Chen Dayue heard this, he thought there was something interesting. "Normally speaking, the courses in this professional direction, like our probability and statistics, involve a lot and are very broad. The core of our probability and statistics are the two courses I teach, application of stochastic processes, and application of randomization. Analysis is very suitable for laying the foundation of our three disciplines of mathematics, physics and computer science.”
"For professionals, you have to learn mathematical statistics, measure theory, functional analysis, partial differential equations, topology, differential manifolds, mathematical models, set theory and graph theory. In fact, our probability and statistics can not only move towards pure numbers, but also Being able to do the counting cannot be defined simply by saying that probability and statistics are all counting.”
"I'm not bragging to you. The old guys from the Institute of Physics have to come to me for help from time to time. I also know a little bit about general physics, theoretical mechanics, and statistical physics. I am also the ordinary head of the Mechanics Department of the Institute of Physics. Level, okay, okay.”
Xu Qingshan was stunned for a while after hearing this.
Isn’t it an introductory subject?
Why did you start bragging?
Director Chen doesn't sound particularly reliable, but he also has advantages. He loves to communicate and can communicate, which makes him very suitable for free prostitution.
If Chen Dayue knew what Xu Qingshan was thinking, his heart would probably break into eight petals.
But he continued talking enthusiastically at this time.
"This undergraduate program basically requires you to master these. If you are still interested in probability theory and mathematical statistics, I think you are very suitable to come to my graduate school. I will personally teach you, starting from the undergraduate degree, just like my former disciple Ding Like an arrow, he is now recommended by me to go to Perez to study for a Ph.D. Yuval Perez is also a master in this field.”
"The graduate courses are more in-depth. You have to learn advanced probability theory, advanced statistics, stochastic process theory, stochastic analysis, functional analysis II, selected lectures on stochastic processes I, modern partial differential equations, introduction to Riemannian geometry, Probability limit theorem, modern time series analysis, these courses may be more difficult for you to study without a teacher, but you can also take a look first to see if you are interested.”
Chen Dayue's enthusiasm almost overwhelmed Xu Qingshan.
It's just that what Chen Dayue said didn't touch on the key points that Xu Qingshan wanted to know.
"No, Teacher Chen. With so many courses, I can't find the key points at the moment. I'm still quite interested in probability theory, but do you have any recommended route for me to learn?"
Xu Qingshan asked again, and Chen Dayue suddenly realized.
Just to show off how much I know and how much I can teach you, I forgot the original question.
"That's it."
Chen Dayue thought for a moment.
"I personally recommend that you read "Probability Theory" in the first stage, and then after reading it, I will give you a test paper. If you can get full marks, continue studying. In the second stage, study "Application of Stochastic Processes", "Real Variable Functions", "Mathematical Statistics". After studying these three subjects simultaneously, you will take the test together. Then in the third stage, you will study "Measure Theory" and "Functional Analysis", and then move on to "Advanced Probability Theory" and "Functional Analysis". II", and finally learn the theory of random processes, so that you can basically lay a very solid foundation in the direction of probability theory."
Speaking of which.
Chen Dayue was already thinking about it.
If Xu Qingshan follows the training plan he recommended, can he still be my student of probability and statistics? Could he still be my disciple, Chen Dayue?
That’s for sure!
This high-end game has been won!
"The foundation has been laid, and you will definitely have been in school for a long time by then. I will teach you "Stochastic Analysis" and "Advanced Statistics", and then take you to participate in seminars, academic seminars, and take you to Hold an academic conference and I guarantee that you will be able to write a valuable paper soon, and then you can easily stay at Peking University to teach.”
Chen Dayue not only imagined, he also said.
Here I was still thinking about continuing to draw cakes for Xu Qingshan, but Xu Qingshan just smiled after hearing this and remembered the learning route mentioned by Chen Dayue.
Professor from Peking University?
This kind of honor may be regarded as the pinnacle of life for ordinary academic masters and ordinary people.
But he is different.
He has his own ideas and his own route.
"Okay, thank you, Teacher Chen. Then I'll buy these textbooks. Will the version of the textbooks be the same as ours at Beijing University?"
"Hey, you don't need to buy them. I can just mail them to you. The most important thing I don't lack here is teaching materials. I will also send you copies of my lecture notes and some information papers. You can study without worry and just ask if you don't understand."
Chen Dayue is full of confidence.
He was so proud of his success in grabbing Xu Qingshan's good seed early that he felt a little carried away for a moment.
"It's okay. Even if you arrive at Beijing University and don't come to the School of Mathematics or our Department of Probability and Statistics, then you are still my student, Chen Dayue. If you need anything, just ask. As long as you can produce some results, I will be satisfied. "
At Chen Dayue's level.
In fact, in academic terms, unless it is a major breakthrough that can win the highest award, they will not be short of even the top journal papers.
There is no shortage of fame, no shortage of money, and no shortage of achievements.
What is missing is the sense of accomplishment that comes from being a great disciple.
"Don't worry, no matter whether I go to Shuyuan or not, I, Xu Qingshan, will be your student for the rest of my life."
Xu Qingshan is also a good talker.
These words made Chen Dayue's heart itch.
After chatting for a while, we hung up the phone.
Xu Qingshan sat on the stone bench in the playground and looked at the quiet and beautiful Longjiang Experiment, and suddenly felt happy.
I got another Peking University department chair for nothing.
And as far as the Chinese academic circle is concerned, Beijing University, Hua Qing University and Qing University are powerful.
After Chen Dayue said this, Xu Qingshan was already included in the ranks of disciples of the School of Mathematics at Beijing University even before he entered school.
Say so.
Xu Qingshan looked at the clouds passing by in the sky.
Hey, how can I become a master just by making a phone call?
Although this is not very accurate, Xu Qingshan does feel a little strange.
I feel that the text quality of 13,000 words is not vivid enough. I don’t know if there are status problems from time to time. I will start with 11,000 words in three regular updates to see if the subscription and rhythm will be better.
This is a new book. If you have time, you can help read it!
