Chapter 609: Proof of existence

in the afternoon.
Stepping on the bell of the class, he walked into the classroom and glanced at the crowded classroom. Lu Zhou smiled and made a simple and clear opening speech, and then began his first lesson in computing materials in his life.
In fact, in a strict sense, the subject of computational materials is not a required course for majors in chemical engineering. The mathematical knowledge and programming foundations involved are still too difficult for undergraduates.
However, with the development of computer technology, the existence of computational materials science is getting stronger and stronger, and Lu Zhou's position as the founder of this emerging discipline has led to this course being stuffed into a special course, and it is still necessary. Choose the kind.
After all, Jinling University has been running such a school for so many years, and it has won such a Nobel Prize. Nuo was not stopped by Lu Zhou, I was afraid that the statue would be erected.
However, in fact, the school thinks too much.
Even if there is no "required" level setting, he does not need to worry about the situation that no one will come to class.
It is not just Jinda's students who are sitting in the classroom. There are even students who come to take lectures from Dongda University on the subway, and even professors who are studying theoretical chemistry and nanomaterials. Even though most people will complain about "difficult" and "unintelligible" on social platforms after listening to the class, in fact, those who take notes in class seriously account for the vast majority ...
Finishing the class with a hundred and twenty spirits, Lu Zhou left the classroom in applause.
Standing in the corridor and glanced at the mobile phone, it was too early to see, so he turned and went to the office of several hospitals.
When he came to the office, several of his students and assistants were here.
Although he has not come to the office to show his face these days, several of his students still insist on attendance every day.
He came to his place and sat down, glanced at the clean and tidy desk, and Lu Zhou reached out and turned over the folder beside him, but he couldn't find what he was looking for, so he asked casually.
"What about the draft paper I put on the table?"
Upon hearing Lu Zhou's inquiries, Assistant Zhao quickly stood up and said, "I'm putting it in your drawer while I help you organize your desk."
Lu Zhou: "Well, thank you ... but I don't need to arrange my table for me, just keep it as it is."
Zhao Huan nodded embarrassedly: "Good professor, I will pay attention."
I found the draft paper in the drawer, and Lu Zhou flattened it on the table, thinking about the lines of formulas written a week ago, thinking about it for a while, and then continued writing along the back of it. .
Glancing in the direction of the landing boat, Feng Jin, who had previously written at the desk, hesitated, and finally made up his mind and stood up and walked towards him.
"professor."
Looking at the student standing near his desk, Lu Zhou in a good mood casually asked, "What's wrong?"
"That question ... have you figured it out?"
Lu Zhou smiled and said, "You looked at something on my paper?"
Feng Jin scratched his cheek awkwardly: "I accidentally glanced ..."
Glancing at the embarrassment on his face, Lu Zhou said nothing.
In fact, he didn't care much about Feng Jin peeking at the contents of his draft paper.
After all, if it's something important, you won't just throw it on the table, even if you don't hide it, you will at least put it in a drawer.
"Then what? Have studied it for a week?"
"... Um," looking at Lu Zhou who didn't care much, while Feng Jin was relieved, he scratched his head in shame, "I tried for a week, but I didn't have any clue."
"It's normal to have no clue. If you can solve that problem, don't read any master's degree, just come to be a professor."
Hearing this sentence, Feng Jin smiled awkwardly.
As soon as he came up, he challenged the Young Mills equation, and he admitted that he was a bit swollen.
Looking at the expression on his face, he probably guessed his thoughts. Lu Zhou smiled and continued, "Tell me about your feelings this week."
Feng Jin froze slightly: "Feel?"
Lu Zhou: "Yes, now that you have said it and thought for a week, no matter if you can think of a solution to the problem, you still have to think of something? Don't tell me you are just facing the draft paper in the office, A bunch of meaningless graffiti. "
Feng Jindi flushed, arguing: "It's not graffiti, and I'm thinking seriously."
With raised eyebrows, Lu Zhou asked, "For example?"
"For example ..." Wanting to say that he was afraid of Lu Zhou's joke, Feng Jin hesitated, and finally gritted his teeth, and boldly uttered his own thoughts. Massless, but strongly interacting media particles can have mass. In this case, if we introduce a scalar field on a space-time manifold, the problem may be simpler. "
Lu Zhou nodded approvingly: "Yes."
Feng Jin looked at Lu Zhou unexpectedly, but he did not expect that he would praise himself.
Lu Zhou: "Do you learn self-mechanism for excess electrons?"
Hearing this sentence, Feng Jin, who had some unexpected surprises, suddenly became depressed.
The professor who came to the boast is not his own idea, but the attitude of knowledge to the extra-curricular knowledge in advance ...
Looking at Feng Jin who nodded reluctantly, Lu Zhou smiled suddenly and said, "You remind me of someone."
Feng Jin froze slightly and asked subconsciously: "... Who?"
"A student I brought with me in Princeton is probably reading a Ph.D. in Witten now. His choice is mathematical physics. You have a little similarity in character, and both are stronger.
Speaking of time, time really passed so quickly that he had left Princeton for more than a year.
I don't know how his students are doing.
Qin Yue is probably still a lecturer at Princeton. Some time ago they also exchanged questions about number theory in the email.
Willa ...
The look was a little subtle and unnatural, and Lu Zhou coughed slightly, ending the topic.
"Dragging away, back to the previous topic, objective evaluation, your idea is not a big problem in a sense."
Upon hearing this, Feng Jin suddenly asked, "Really?"
"... Don't be in a hurry, what I'm talking about is just that there are no major problems," seeing Feng Jin's excited face, Lu Zhou continued, "However, in physics, it is not necessarily convenient Means right. "
"Doesn't mean ... right?"
"Yes," looking at Feng Jin who was there, Lu Zhou nodded slightly with approval, "Wait someday you can really understand the meaning of the sentence I said, the truth is far away from you Near. "
...
It was taken at school until six in the evening.
When Lu Zhou returned home from school, it was basically dark outside.
He walked straight into the already renovated study, opened his chair and sat down. He quietly picked up his pen and started to finish the final proof for the morning certificate.
Sometimes math problems are so magical.
After a line of thought has been worked out, and it can be continued foreseeably, the subsequent process is just a matter of course.
After finishing the last line of formula ~ EbookFREE.me ~ Looking at the stack of draft paper, Lu Zhou's mouth evoked a pleasant smile.
Although it is not a decisive result, it can be at least a phased result.
That is, the existence of a solution to the Young Mills equation is proved using a mathematical method.
The first half of the first part of the millennial puzzle about the Young Mills equation, this section of the question is actually not challenging for him.
Although he also used some mathematical skills to solve this problem, there is no innovative method.
Basically, the core part of the whole proof revolves around the L-manifold he figured out when solving the NS equation problem.
In any case, this problem is considered to be solved.
The next step is to find a general solution to the Young Mills equation ...
Compared to the existence of a separate proof of the existence of a solution, this part of the problem is undoubtedly more challenging ...
