Chapter 425

”when did you come back?” Professor Fang asked Cheng Nuo as he walked into the room.

”The 19th.” Cheng Nuo replied.

”There's a lot of pressure there, isn't it?” Professor Fang continued.

”Not bad.” The pressure does exist, but it is still within the range of Cheng Nuo.

He raised his hand and handed Professor Fang the bag he was carrying in his right hand. ”I brought some special products from home.”

”Then I will not refuse and accept it directly.” Professor Fang accepted it with a smile.

Walking into the living room, Cheng Nuo finds another person sitting on the sofa, sipping with a teacup in both hands.

”Oh, Cheng Nuo, let me introduce you. This is Professor Zhou Hong from the school of mathematics of Jinling University.”

”Hello, Professor Zhou!” Cheng Nuo said hello politely.

Professor Zhou and Professor Fang are about the same age, but they look much younger than Professor Fang.

Seeing Cheng Nuo, Professor Zhou raised his head slightly, and then his eyes brightened.

He got up, walked up to Cheng Nuo, warmly held his hand and said, ”are you Cheng Nuo's classmate?”

”Well, it's me.”

This is the first time they have met. It seems that Professor Zhou is a little too enthusiastic about himself, so he can only respond to him by chatting.

Professor Zhou just shake hands is not enough, finally seems to be in a mood to suppress, directly give Cheng Nuo a big hug.

Cheng Nuo's face was changed again and again by Professor Zhou.

This is Are you doing that?

Professor Zhou is so enthusiastic that Cheng Nuo doesn't know how to parry.

It was not until Professor Zhou's next sentence that Cheng Nuo suddenly realized.

Professor Zhou relaxed Cheng Nuo and patted Cheng Nuo heavily on the shoulder, ”classmate Cheng Nuo, your” Cheng Nuo theorem ”is very embarrassing to us Chinese mathematicians.”

Cheng Nuo rubbed some aching shoulders and said with a bitter smile, ”I didn't expect that disgraceful thing had spread to China.”

”Disgraceful?” Professor Zhou was stunned and retorted, ”ah, how can it be disgraceful! You don't know how exciting it was for the Chinese mathematical community to hear about your big moves at this International Congress of mathematicians

”When I heard the name of Cheng Nuo theorem, I knew that it was put forward by Chinese people, but I didn't know where the” Cheng Nuo theorem ”was. At that time, I still remember Lao Fang said that he had a student studying in the United States, which happened to be Cheng Nuo. We all took it as a joke and didn't pay much attention to it. ”

Professor Zhou was obviously very talkative, and continued to tell Cheng Nuo, ”but guess what, when we saw the live video, Lao Fang immediately recognized that the young man on the stage was his student, that is you, classmate Cheng Nuo!”

Professor Fang just stood aside, smiling and silent. He nodded to Cheng Nuo when Professor Zhou mentioned himself.

Professor Zhou gasped slightly, suppressing his inner restlessness.

Although Cheng Nuo's mind has no concept about the influence of Cheng Nuo's theorem on Chinese mathematics, Professor Zhou, who has been with the Chinese mathematical circle for more than 20 years, naturally and clearly understands this significance.

Mathematical theorem, also known as mathematical axiom, refers to the formula or text with universal application.

Different from conjecture that hard to ”create”, mathematical theorem is the existence, but lack of people to ”discover”.

Even if they all belong to mathematical theorems, they will be divided into three or six grades.

For example, those mathematical theorems mentioned in the textbooks of junior high school and senior high school are basically those of the first echelon. Belong to a field, the most basic but also the most important universal axiom.
