Chapter 147 Let's Go to the Stage and Speak

After that number theory class, Lu Zhou also listened to a section on complex variable functions with the number one and two class of Shuying. After all, this class is in his schedule. The roommate went to listen, and he followed suit.

As a result, as soon as the class was over, the teacher saw him sitting there, smiled and pulled him up to speak for himself.

From the expansion of the complex plane to the Riemann sphere, Lu Zhou was not very proficient at the beginning, but later he became much more fluent.

However, when he was lecturing, he obviously ignored the acceptance ability of other people.

Lu Zhou spoke seriously on the stage, but the students in the audience were stunned.

Only a few people can keep up with his rhythm, such as Luo Rundong, the second student in Class 1 of Shuying. There are still a small number of people who can barely keep up with his rhythm, such as Liu Rui in the same dormitory...

"...The transformation function between the ζ-coordinate and the ξ-coordinate can be obtained by combining one of the mappings with the inverse of the other, and can be obtained through a not very complicated transformation. The unit sphere and the Riemann sphere are diffeomorphic."

He said it was not very complicated, but Lu Zhou, who had his back to the classroom, never stopped chalking on his hand.

This time, the classmates who were barely keeping up with the rhythm, now joined the army of billion-faced bullies.

And people who could keep up with the rhythm gradually began to feel strenuous.

For example, Luo Rundong, staring at the blackboard and frowning, thought for a long time before writing a few strokes on the draft paper.

Liu Rui's eyes were staring straight, the pen in his hand simply stopped, and he complained in a low voice.

"Damn it, what is this writing???"

Huang Xiaojian, who was sitting next to him, looked at the blackboard and blinked.

He wasn't confused, because he didn't listen the whole time.

"Little bitch, do you understand?"

"No," Huang Guangming shook his head vigorously, "Brother Lu said that he would die if he said to give points. Isn't it a basic operation if you don't understand something that Brother Lu said?"

Liu Rui was stunned.

It makes sense, but he couldn't refute it for a while.

Lu Zhou on the stage had finished writing on the blackboard, and stood aside to let the students in the classroom take notes.

The students in the first row were the first to come to their senses and took out their mobile phones to take pictures. The students in the back row were still still.

The old professor, who had been fishing beside him, put down the thermos with a smile on his face, walked to the podium, and tapped something on the blackboard.

"Remember, there is an exam at the end of the semester."

There was wailing in the classroom.

Looking at the almost full blackboard and holding up their mobile phones to take pictures, a few students had smiles on their faces, but despair in their hearts.

They don't want to say anything except one MMP.

Huang Guangming poked Liu Rui, who was about to go crazy, and said happily, "It's okay, anyway, brother Lu is in our dormitory, so I'll understand after PY at night."

Liu Rui ignored him.

His madness was not entirely due to the fact that his head was about to explode.

But because, his desperate discovery...

Is the gap already that big?

...

It is impossible to attend class, at least math class is impossible.

After that complex change class, Lu Zhou never went to math class again.

The same is true for him, the courses in this major are no longer interesting, and the occasional class at the zoo has become his new pastime. As for normal times, he still goes in and out of the library more often.

Except for the time when I went to the library, it got better afterward.

After explicitly declining several invitations to collaborate on papers, there were fewer people who bothered him.

After all, everyone has their own things to be busy with.

Enthusiasm is something that needs to be vented once.

Of course, it may also be because Lu Zhou sat in the corner of the library very low-key every time, and never came on time for the opening of the library.

I devoted myself wholeheartedly to the writing of the thesis.

When writing a thesis, for Lu Zhou, it was actually a learning process.

In order to introduce the Hilbert space into quantum mechanics and use mathematical problems to study the laws of motion of microscopic particles, he has read a lot of papers and took a few advanced quantum mechanics courses for graduate students.

It has to be said that Jin University is quite capable in the field of theoretical physics. What the old professor said in class inspired Lu Zhou a lot.

Of course, although the problems of quantum mechanics are fascinating, mathematics is his basic disk.

Therefore, when writing this paper, he still uses mathematical thinking to think more.

As for the things about quantum mechanics, it is just a superficial touch in the process of discussion.

[Equilibrium Problems in Hilbert Space and Viscous Approximation Methods for Finite Nonstretchable Maps]

【Abstract: In the real Hilbert space, a new iterative scheme is introduced, using the method of viscous approximation to approximate the common elements of the solution set of the equilibrium problem and the fixed point solution set of the finite nonextensive map, and get There is a strong convergence theorem. 】

In the last step, Lu Zhou wrote an abstract for the thesis, which can be regarded as a summary of the work during this period.

"You're done!"

Looking at the completed thesis, Lu Zhou let out a sigh of relief and entered the system space to confirm the progress of the next task.

Bonus task: Literature reading (13/50).

Just from the completion of this task, it is not difficult to see how much effort he has put in during this time.

Fortunately, these jobs are over.

All that was left was to change the thesis to the format of a graduation thesis and hand it over to Professor Tang.

Then he can start making PPTs and prepare for graduation defense.

As for the paper, he plans to translate it and submit it to Advances-in-Theoretical-and-Mathematical-Physics.

The Chinese translation of this journal is "Advances in Theoretical and Mathematical Physics", focusing on all areas where theoretical physics and mathematics interact, with an impact factor of 2.3. Although this IF value is not very high, this journal is quite prestigious in this field, and it belongs to the core journals of the first district.

These two jobs can be done at the same time without conflicting with each other.

After finishing his graduation thesis, Lu Zhou went to Lao Tang's office and handed in his research results of the past month. It was regarded as the final answer sheet for his undergraduate career of less than two years.

in the office.

After briefly reading Lu Zhou's graduation thesis, Professor Tang said.

"The point of view you put forward in the paper is very novel, and the research on real Hilbert space has many overlaps with my own research field. However, I will not ask you specific questions here. I will wait until the time of defense. Ask me again."

"I hope the teacher will hold your hands high." Lu Zhou smiled modestly.

Professor Tang smiled and said, "Heh, you're still afraid of me being picky? You can start preparing the PPT for your defense. Remember to put in some effort. There are quite a few people who want to be your defense judges, and you will be lucky when the time comes."

Lu Zhou coughed and said, "Professor, you shouldn't embarrass an undergraduate student."

"No, no, just ask a few random questions." Professor Tang waved his hand and said with a smile, "Dean Qin and I will definitely not embarrass you, but there are two old guys who read the topic you chose , if you insist on running over to be your defense teacher, you won't be able to stop him."

Lu Zhou asked cautiously, "Can I ask who it is?"

"It's okay to tell you," Professor Tang paused, and continued, "One is Academician Lu Shenjian from our school, and the other is Academician Xiang Huanan from the Chinese Academy of Sciences."

Hold the grass?

Professor Xiang Huanan didn't hear much about Lu Zhou, he only knew that he was the deputy director of the Mathematical Society. Lu Zhou has only read one of his papers, which seems to prove Lusztig's conjecture about the base ring for the affine A-type Weyl group. In short, this is also a bigwig in the field of algebraic groups and functional analysis.

As for Academician Lu's name, it was like a thunderbolt.

His identity is a member of international cooperation groups such as BESIII and LHCb, and in 2013, he discovered the tetraquark state Zc(3900) in the experiment of the Beijing Positron Collider, and this discovery was rated as one of the top ten advances in physics in the world that year head! Let the physics community in Huaguo feel proud internationally!

Although it is a great honor for these two big bosses to take time out of their busy schedules to give a graduation defense for this undergraduate student, at this moment, Lu Zhou has only one feeling in his heart.

I just want to get a diploma, as for...

Lu Zhou thought dumbfoundedly.
