Omnipotent Data

Chapter 397

"Graduate student majoring in mathematics?" The young man was taken aback first, then shook his head and smiled, "This article is not something a graduate student can understand."

Cheng Nuo shook his head, "That's not necessarily!"

"Oh?" The young man smiled, looked directly at Cheng Nuo's plain face, and smiled, "Then I will wait and see!"

The young man looked at Cheng Nuo, holding his arms, with a faint smile of disdain at the corners of his mouth, saying that he would like to start your performance.

Cheng Nuo ignored the young man. Instead, he lowered his head and fixed his gaze on the middle-aged man who had been sitting beside the young man without saying a word.

Cheng Nuo leaned down slightly and said with a smile, "This article should mainly describe the derivation of related formulas in the complex projective space of algebraic geometry in the Euclidean space with infinite points. Professor Russell, I Are you right?"

The middle-aged man raised his head suddenly and asked, "Do you know me?"

Cheng Nuo smiled, "Professor Russell is a big figure in the field of geometry, how can students not know him. I am currently focusing on geometry, and the teacher has let us read some of your papers!"

Russell didn't expect anyone to know himself, and he seemed to be an admirer of him.

He pushed his glasses and smiled politely, "My job as a mathematician is to write better papers to educate the next generation of you. If I have the opportunity, I can give you pointers. Oh, yes, I take the liberty to ask, which professor is your teacher, maybe we still know him."

"Oh, the student's teacher is Professor Fresnel." Cheng Nuo said.

Russell looked stiff.

His main field of geometry is good, and he is fairly well-known in this circle, but compared with Professor Fresnel, he is insignificant and has no comparison at all.

Among all the mathematicians who are still active in the academic circle of geometry, Professor Fresnel is the well-deserved first.

And a Professor Russell who was only invited to participate in the International Congress of Mathematicians and mixed into a small lecture with dozens of people was naturally not qualified to give advice to Professor Fresnel's students.

Professor Russell immediately became enthusiastic, with a cordial smile on his face, "Professor Fresnel is my idol. When I was young, I had the idea of ​​studying from him, but he didn't see him. You. As a student of Professor Fresnel, I am very envious! When you see Professor Fresnel, you must say hello for me!"

Cheng Nuo smiled and nodded, "Definitely."

"Oh, yes, this is my first student, Myron, now a lecturer in the Department of Mathematics at the University of California." Russell introduced the young man next to Cheng Nuo.

Cheng Nuo glanced at Myron deeply, without speaking.

The young Myron smiled slyly, and said haha, "It turns out that everyone is a friend. Then this little brother, you won't pursue the issue of the flight attendant with the wet information in your hand. After getting off the plane. I just print another copy."

Cheng Nuo shook his head and shrugged, "That's not necessary, the teacher's article, if I can't complete it, isn't it too unqualified for me as a student?"

"Have a pen?" Cheng Nuo reached out.

"Oh, yes!" The young man was in a daze, took a pen from his pocket and handed it to Cheng Nuo.

Cheng Nuo has read the part of the paper soiled by coffee.

After taking the pen, he wrote directly in a place where it was not wet.

[Given an n+1-dimensional complex Euclidean space Cn+1, consider the subset Cn+1{0}. Introduce the equivalence relation as follows: If for the points (z1, z2,..., zn+1) and (1, 2,..., n+1) in Cn+1{0}, there is a non-zero complex number ρ, such that ……】

[From the n-dimensional complex projective space CP, take out the equivalence classes with the point (z1, z2,..., zn, 1) as the representative elements. These equivalence classes form a subset of CPn, where each point corresponds to C Point (z1, z2,..., zn), this is a one-to-one correspondence to C. It will be regarded as equivalent to C, and then...]

[Let Ui (0≤i≤n) be the whole point of coordinate Xi≠0 in PR, then UiR, and U0, U1,..., Un constitute an open cover of PR. ……Establish the n-dimensional projective space PK on K. In the theory of generality, the projective space is also built on the integer ring Z, that is, the projective generality PZ is established. Therefore, PX can be established for any outline X to create fiber product. 】

When the pen was written, Cheng Nuo placed the paper and pen in the young man's hands in the shocked eyes of the flight attendant.

Cheng Nuo stood in front of the young man with a straight voice, giving him a feeling of needing to look up.

"Hey, this is the missing part of the article. Now, can you let the stewardess go?" Cheng Nuo asked.

The young man nodded Mumu, "Yes, you can..."

Cheng Nuo shrugged, returned to his seat and sat down.

"Sir, I really thank you just now." The flight attendant said to Cheng Nuo in a grateful tone, and the azure blue eyes were full of brilliance.

Cheng Nuo waved his hand, "It's just a matter of raising a hand, besides, they just quarreled me to sleep."

flight attendant:"……"

So I didn’t want the hero to save the beauty, so disappointed...

…………

No words all the way.

After more than four hours of voyage, no accident happened again.

The plane landed slowly at the Philadelphia airport. Cheng Nuo awakened the dozing Tan Weiwei and whispered, "We are here."

Cheng Nuo pulled two suitcases and Tan Weiwei, who was in a daze, stepped off the plane. Before he took a few steps, a voice came from behind him.

"This classmate, please wait a minute."

Turning to see, it was Professor Russell and his very poor-tempered student.

"Did you two come to Philadelphia?" Professor Russell asked curiously.

Cheng Nuo smiled, "Didn't you hear that the International Conference of Mathematicians will be held soon. Come join in the fun."

"Then Professor Fresnel?"

"Oh, the teacher will come tomorrow. By the way, I forgot to ask. Professor Russell must have been invited to this conference of mathematicians?"

"That's natural!" Professor Russell hadn't spoken~www.readwn.com~ His student spoke first, with his head held high, with a proud look, "My teacher not only received the invitation, I was also invited by IMU to give a lecture on the fifth day of the conference."

Cheng Nuo smiled, "If there is a chance, I will definitely go over to join Professor Russell!"

After saying goodbye, Cheng Nuo turned and left.

Professor Russell stood there and pondered for a few seconds, then turned to the young man and said, "He said he was going to cheer me up?"

The young man nodded, "He did say that just now. I think it's because of the teacher's reputation. He should still admire you."

Russell frowned. "I'm not talking about this."

"He is just a graduate student, and it is impossible to receive the invitation letter from this International Mathematician Conference. Why did he go to cheer me up?"

"This..." The young man slapped his head, "Could it be that we were tricked by him?"

Russell shook his head, "That's not good."
