Chapter 148: Graduation defense (4/4)

After a long preparation, it was finally the day of reply.
There were four judges in reply.
In addition to Dean Qin of the Academy, it is Professor Tang.
In fact, according to general regulations, there are instructors to avoid the system, but Lu Zhou's situation is special, and the process of defense is also very different from that of ordinary graduates. No one cares about such trivial matters.
In addition to the two Lu Zhou knew, the other two were one from Academician Lu Shenjian from the Jinda Museum, and the other from South China Academician Xiang Hua from the Chinese Academy of Sciences. At the same time, this professor Xiang is also an associate director of the Chinese Mathematical Society.
These two big brothers are not small, he has known before.
Standing on the podium, Lu Zhou looked as usual.
For this moment, he has been preparing for a long time, naturally there is no stage fright.
The PPT started showing.
After Lu Zhou introduced himself in accordance with the process, he began to read the dissertation, and briefly reported the main points and conclusions of the dissertation.
This process is very short, and it takes only five or six minutes.
The next question link is the top priority of the defense!
Professor Xiang Huanan's eyes were sharp and he asked straight away.
"On the fifth page of the paper, in line 11, I noticed that you mentioned in the paper that let C be a non-empty closed convex subset in Hilbert space. I have a Halpern type sticky iterative algorithm, what is the significance, can you explain it in detail? "
If it is a graduation reply of an ordinary undergraduate student, the answering judge will certainly not ask such a tricky question, but the person standing on the podium is not an ordinary undergraduate student, and the person sitting below the podium is not an ordinary answering judge.
Naturally, it will not be a common question.
There is no need to touch the thesis, what Lu Zhou naturally wrote at the beginning of the fifth page.
"It is used to prove that the sequence {xn} generated by 'Formula 8' strongly converges to a fixed point on T, and this point is the only solution to variational inequality V. In a detailed explanation, the mathematical problem is unclear in two words, Can I use the blackboard? "
Professor Xiang Huanan said with a smile: "Of course."
Normally it won't work, but that's just normal.
Picking up chalk, Lu Zhou is writing on the blackboard.
[X1 ∈ C, x (n + 1) = αn · f · xn + βn · xn + γn · T · xn, n≥1. Where f: C → C is a compressed image, where T: C → C is a non-stretched impression ...]
He narrowed his eyes towards South China and nodded approvingly, "Yes."
The respondent's qualifications are quite high, even by the standards of a doctoral student.
At least, this answer made him very satisfied.
Standing beside him, Professor Lu Shenjian said slowly: "I also ask a few questions."
Lu Zhou respectfully said, "Teacher, please."
Professor Lu Shenjian: "I noticed that you mentioned in your thesis that the application of your sticky iterative algorithm can also be used to study the pre-solutions of maximal monotone operators in Banach space, and this may become a research A tool for quantum mechanics. This is similar to the algorithm mentioned by Professor Kohsaka of Japan when he introduced non-stretching mapping in 2008, but you have not extended it further. Why? "
This problem actually caused Lu Zhou to chat for two seconds.
How can this be?
Because the point of this paper is not this!
Lu Zhou coughed and said, "Because you can write a dissertation by deriving further. This dissertation only discusses mathematical problems. Although it mentions applications in quantum mechanics, it does not involve specific content."
The academic problems are endless, and everything is extended a little. The dissertation written here is a kind of difference. Including his possible application of the sticky iterative algorithm in quantum mechanics, he only mentioned a few sentences.
Professor Lu Shenjian shook his head and preached in a long and focused voice: "This is not the mentality that a scholar should have, and you should strive to be perfect in your studies. Now that you have discovered this possibility, why not follow this idea and continue to dig Go down? "
Professor Xiang Huanan smiled suddenly and said: "Lao Lu, don't embarrass our classmate Lu. People who are good at mathematics are not necessarily good at physics. I think our classmate Lu is more suitable for research in the field of mathematics. . "
Professor Lu Shenjian raised an eyebrow: "I didn't say that. I mean, if he is interested, he can learn from me. The motion of microscopic particles needs to be regulated in Hilbert space, and vice versa , Observation of microscopic particles, and his research in the field of mathematics will certainly have a greater inspiration! "
"I don't agree," said Professor Xiang, shaking his head slowly, and said slowly. "I have also done a lot of research on excess subgroup theory and Yang-Baxter equation. Although mathematics can be a tool for physical research , But the mathematics itself is self-contained. The use of tools and polishing tools, after all, are two things. "
Having said that, Professor Xiang smiled, looked at Lu Zhou, and suddenly Feng Feng said, "As Professor Lu said, you have discovered a novel clue. Why not dig along this clue?" The Math Institute has a similar research project if you are interested ... "
President Qin, who has not spoken, coughed, interrupting his words: "You have so many talents from the Chinese Academy of Sciences, don't rob us, are you sorry?"
Professor Xiang Huanan didn't blush, and said with a smile: "I'll make such a suggestion casually."
Professor Tang grinned and did not expose him: "There is still time, please continue to reply."
In fact, there is nothing to ask.
Is there any reason to be able to write a graduation thesis of this level?
The so-called defense is just to test the authenticity of the thesis and to check whether the level of the students has passed. This goal was actually achieved before the reply began.
"What else do you want? Do these formalisms cleanly!" Mr. Xiang Lao was quite straightforward. He filled in the scores on the form and stood up with a smile.
Seeing the landing boat, he nodded with satisfaction. "Your accomplishments in the field of functional analysis surprised me. I rarely see undergraduates making such a wonderful answer."
Lu Zhou said sincerely, "Thank you teacher."
"No thanks, the reply is over," he waved to South China, "you go out first."
Lu Zhou looked at Professor Tang.
Professor Tang nodded: "You go out first, and you will be notified soon."
After the defense, the students responded in accordance with the process. The judges and teachers exchanged opinions, and gave a total score of 100 to the defense, thesis, and on-site performance. Evaluation.
Passing is definitely no problem.
If this doesn't work, I'm afraid no one can graduate from this school.
Out of curiosity, Lu Zhou wanted to take a look at how many points Xiang Lao gave his final evaluation, but the paper was a little far away and could not see at all.
After Lu Zhou left the classroom, the classroom was quiet for a little while.
Looking at Professor Tang, Mr. Xiang smiled: "Old Tang, I haven't brought any students in these years. This person is very old and is about to retire. I want to find someone to inherit the mantle. Convenience?"
Professor Tang grinned and looked at the old friend: "It's no use asking me here, I support this boy wherever he goes. You might as well ask the old Qin next to me."
Lao Qin smiled, but before he spoke, Academician Lu glanced at the old guy: "Don't even think about it!"
He pursed his lips toward South China, shook his head and sighed, "Stupidly."
In fact, he just asked such questions casually. If Ken Song is here on Jin Da's side, it would be a coincidence. Not to mention that he is useless, the director of the Institute of Mathematics is here, and most of the same.
However, today's trip, UU reading www.uukanshu.com is also satisfied with his curiosity.
The old guy Wang Xiuping bragged with him, saying that Jin Da had a little Tao Zhexuan. No accidents in 20 years, Hua Guo would have a Fields Medal.
Hearing this sentence, he didn't believe it. After all, the old man did not brag once or twice, and there were two "Little Tao Zhexuan" in Yanda.
But today he saw it, he believed it.
Thinking of this, Mr. Xiang could not help feeling in his heart.
"If young scholars are prosperous, then academics are fortunate, while academics are prosperous, but Bangxing is ... well."
In fact, even if he is not studying under his control?
By his age, a lot of things had been looked down on.
And those things that are not understated ...
He believes that he must have a chance to see it.
