The Science Fiction World of Xueba

Wang Chongqing laughed: "These should be the students who listened to Teacher Pang yesterday. It is normal to see Teacher Pang excited. The linear functional analysis of Teacher Pang yesterday, I also benefited a lot from listening! Yes, Teacher Pang, What are you going to do today ’s report? How are you preparing? "

Xi Pang Xuelin said with a smile: "I'm ready to go and report at any time."

King Chongqing said: "That's good, it's not too late now, let's go to eat first, and then go straight to the ladder classroom after dinner."

"Row!"

Next, Pang Xuelin and Wang Chongqing's father and daughter went directly to the school cafeteria for dinner. After dinner, they went straight to the staircase classroom where the lecture was held.

When the three of them arrived, many people had already arrived in the classroom, and Luo Jianzhong, director of the mathematics department, was also present.

At this lecture, not only the majority of professors, associate professors, and lecturers in the Department of Mathematics were present, but also many students from the Department of Mathematics who were informed came over to watch.

I saw Pang Xuelin and they came in. Luo Jianzhong led several professors in the mathematics department to welcome him.

"Mr. Pang, you have finally arrived. Let me introduce you. This is Professor Zhang Jie of our Department of Mathematics. His main research direction is partial differential equations. This is Professor Xie Weijun. His main research direction is topology and dynamic systems. This is Professor Liu Yuan. His main research direction is algebraic geometry ... "

Luo Jianzhong introduced the professors of mathematics to Pang Xuelin.

"Hello Professor Zhang ..."

"Professor Xie, hello ..."

"Professor Liu, hello ..."

Uh ...

Xi Pang Xuelin shook hands with the backbone scholars of the Mathematics Department of Lincheng University.

Off the stage, with the exception of those students who had heard Pang Xuelin's lecture yesterday, most people looked at Pang Xuelin with a hint of curiosity.

From time to time I can hear some scholars whispering.

"This teacher Pang looks too young, does he really have such a powerful legend?"

"Director Luo and Professor Wang shouldn't look away. It is said that after looking at the papers he wrote, Director Luo thinks that this young man is enough to rank among the top mathematicians in China."

"I really don't understand why such a person would be a teacher in a rural elementary school."

"Who knows?"

Uh ...

After Wang Muhui entered the classroom, she sat down in the stepped classroom.

女生 A girl is sitting beside her.

沐 Wang Muhui was curious: "This classmate, did you listen to Teacher Pang yesterday? How did this teacher Pang say?"

The girl took a look at Wang Muhui and said, "You came here after listening to the rumors about Teacher Pang. I tell you, I will definitely not disappoint you. I took this semester for functional analysis Before he learned it, yesterday Mr. Pang made everything clear and clear, and the lecture level was much higher than that of Professor Wang. "

"Uh ..."

Wang Muhui could not help but feel a little awkward.

Cooperating with his father, Pang Xuelin was also beaten.

At this time, another person sat down beside Wang Muhui. When Wang Muhui turned her head, she couldn't help but faint a little: "Uncle Zhang, you are here."

Zhang Hewen said with a smile: "I'm not late!"

Wang Muhui said, "No, we have just arrived."

Zhang Hewen said: "Xiao Hui, I have a day with Teacher Pang today. Did you find any special circumstances?"

Wang Muhui shook her head and said, "Today I followed him for a day at the wholesale market. It seems that he really wants to do a small business a year ago to make some money. I don't know what he thinks. With his talent, he can clearly Live a good life in the city ... "

Zhang Hewen laughed: "It's very behavioral, and if this teacher Pang really goes to the market to sell things, you have to follow him ..."

"Relax, Director Zhang, I'm staring!"

【零零 看书 00ks】 ……

The two were talking. At this time, Luo Jianzhong stepped onto the podium and said, "Hello everyone, everyone is welcome to come to Mr. Pang's academic report. I believe that everyone here yesterday has heard about it and I can tell everyone It ’s true. Although Mr. Pang is only a primary school teacher, he has deep research in all areas of mathematics. Below, we have invited Mr. Pang to come to the stage to make a report for everyone. "

Not long after, there was a burst of applause in the classroom.

Except for those students who have heard Pang Xuelin's lectures, most mathematics scholars are looking at Pang Xuelin with his eyes.

虽然 Although they trust Luo Jianzhong and Wang Chongqing's vision, how well Pang Xuelin's true level depends on the performance of Pang Xuelin in this report.

Xun Pang Xuelin walked up to the podium without hesitation. His mentality was very calm. On such occasions, it was nothing at all for the reports he had experienced before.

He looked around and smiled, "Hello everyone, thank you very much, Director Luo, for giving me such an opportunity to do an academic lecture at Lincheng University. I believe everyone has heard of it. Yesterday, I took the lead and grabbed Professor Wang. In a class that gave students a section on linear functional analysis. Today, I will continue to report in the field of functional analysis ... "

The voice under the stage gradually quieted down ~ www.NovelMTL.com ~ Only Pang Xuelin's voice echoed in the classroom.

"The theory and methods of non-linear functional analysis have become one of the research hotspots in the international mathematical community in recent years because of their extensive and important application background. Today, I want to explain my personal research in non-linear functional analysis. Some new progress made in the report. The report is mainly divided into the following three parts, the first part, p (x) -equation and Zhikov conjecture, the second part, the variational principle and its application, the third part, non-smooth analysis ... "

"Zhikov guess?"

Off the stage, many people know that the face of this conjecture has changed slightly.

Luo Jianzhong, who was sitting beside Wang Chongqing, wondered, "Lao Wang, what is Zhikov guessing?"

千 There are thousands of conjectures in the field of mathematics. Therefore, even Luo Jianzhong, whose major research direction is topology and combinatorics, is not particularly familiar with this conjecture.

Chongqing Wang said: "The Zhikov conjecture is a relatively important conjecture in the field of functional analysis. This conjecture was a conjecture proposed by the Soviet Soviet mathematician Zhikov in the partial differential equation seminar of Moscow University in 1982. The main content of the conjecture is, when p (x) is a smooth function with a saddle point on Ω, the function f that satisfies certain conditions can be non-regular. This conjecture has been publicly proposed in many papers. Including Zhikov himself, there are international Well-known mathematicians in the field of less general analysis have studied this conjecture for more than ten years, but it has not been solved. If this conjecture is solved, there may even be a chance to be listed in the four major journals ... "
