Discuss the multiple effective solutions of the universal asymptotic pattern and the Lyapunov stability? ”

"The construction of this plane self-consistent system is very critical, the idea is very clear and clear, there is nothing special that needs to be modified, and the construction of this equation system is also clever."

Xiang Jun looked at these things written by Su Mu, Rao is usually cold, and he couldn't help but show a look of appreciation, and while speaking, he nodded to himself, as if he was affirming his analysis.

Xiang Jun took out a piece of scratch paper and a pen from the table, and immediately began to calculate and draw, wanting to verify some of Su Mu's effective points, many things must be actually operated to reach conclusions, but when he calculated and charted, he found that because Su Mu's ideas were very smooth, he just copied Su Mu's content ideas!!

Zhao Yuhui next to him was stunned.

Although Xiang Jun usually does not smile, he is still very good academically, not only with the classes of the third and fourth years, but also in the graduate tutor, the subject ability is also quite strong.

Therefore, when Xiang Jun was interested in Su Mu's content, Zhao Yuhui couldn't help but draw his head closer, wanting to see what was written.

Ten seconds passed.

Zhao Yuhui slowly retreated.

The face is a little unnatural.

“.......

There was no word for a while.

Because Zhao Yuhui found that he couldn't understand Nima.

He had studied differential dynamical systems.

But he couldn't figure out what these formula symbols meant when they were put together, it was a bit too much.

Although he could see that some of Su Mu's processes were very ingenious, he was a little confused now because he didn't specialize in it very deeply before.

Time passed slowly, Xiang Jun looked at Su Mu, pushed the things he calculated on the table closer to Su Mu, and said:

"The general direction is very novel, and some details are also in place, and the few places I marked are mainly some directions that can be extended and studied."

"For example, the trajectory structure near the singularity of nonlinear systems, as well as linear constant coefficient systems, can be discussed again, can you understand what I mean?"

"Huh?"

Su Mu turned Xiang Jun's scratch paper, looked at the things he marked carefully, and his eyes instantly brightened a lot.

I have to say that the strength of this teacher is really strong.

These two positions are the two weakest points of Su Mu's research during this time, I didn't expect Xiang Jun to see it directly at a glance, Su Mu because he could find it that could be skipped in the end, so he didn't discuss it in detail, and directly came to a conclusion, as Xiang Jun said, if you expand the discussion again, and then connect it with the later text, the whole paper will be richer and fuller.

"Got it."

"Thank you, teacher."

Su Mu nodded politely.

"What's so thankful for this, your paper is really good."

Xiang Jun once again expressed his affirmation of Su Mu and closed the pen in his hand. The eyes he looked at Su Mu now were already full of kindness, where was there still half a minute of indifference when he came in before?

This kind of serious and rigorous students are like treasures falling from the sky for teachers who are engaged in research. Even if you are not your own student, it is a very good experience to see that the students write their papers in such a comprehensive and pleasing way.

Zhao Yuhui: "......"

“emmmmm....”

You get it?

Looking at Su Mu's serious nodding expression, Zhao Yuhui was stunned for a while.

He could see that Su Mu really understood.

And that's the crux of the matter.

His paper has been revised three times, and the time spent discussing with Xiang Jun has been at least four or five hours, and in the end it may not be finalized.

Then, Xiang Jun only read the senior's thesis for five or six minutes, and after calculating it, there were only less than ten sentences in the entire dialogue! And so it ended???

it...

Now, Zhao Yuhui's heart can't say anything except for some slots.

......

......

"What class are you from, why don't you seem to have seen you before, which tutor's student are you?"

Xiang Jun opened his mouth and asked Su Mu.

Whoever can write this kind of thing, in his eyes, must also be a graduate student.

Chen Bing has not taken students for the past two years, and Su Mu should not be Chen Bing's direct subordinate, so Xiang Jun is really curious, why Su Mu is so good at studying differential dynamical systems, and he didn't find it when he recruited researchers, and missed such a good seedling.

This kind of top student, no matter which laboratory he is in, this kind of logical thinking is definitely one of the best.

"Uh...."

Su Mu was speechless for a while.

He originally thought that no one would care about this, but he didn't expect Xiang Jun to ask after all.

Chen Bing's face on the side was also very strange, and he replied instead of Su Mu:

"He's not from our academy... He is from the Faculty of Physics. ”

"The ??? of the Faculty of Physics"

Xiang Jun's face was a little surprised:

"It's a pity."

Su Mu's mathematics is really strong, just from the basic skills, he has reached the level of top students majoring in mathematics.

However, it also dawned on me a lot, the School of Physics will also produce many top math students every year, if Su Mu is the School of Physics, it can also explain why I haven't seen him.

Mathematics and physics were subjects in their own right for a long time, and Newton worked as a physicist, mathematician, and astronomer, establishing the theory and methods of calculus, and in his later years studied theology. Descartes is considered the father of analytic geometry by formulating the geometric coordinate system, and at the same time applied his coordinate geometry to the study of optics, and made the first theoretical deduction of the law of refraction in "Refractive Optics".

A qualified mathematician will have a great advantage in physics, and a physicist will naturally use many mathematical tools

Originally, Xiang Jun wanted to say that if Su Mu's tutor was someone he knew, he would see if he could have the opportunity to bring Su Mu over to help him do the project or something, but the group of people in the School of Physics regarded the students as treasures and were definitely unwilling to lend them, so Xiang Jun could only say that he sighed a little alone in his heart.

"Well, come on, if you have any questions in the future, you can ask me, just come to this office and find me, it's usually here."

Xiang Jun smiled at Su Mu.

Although Su Mu is a student of the School of Physics, he can love mathematical knowledge, which is enough to be worthy of his teaching.

"Yes, Su Mu, if you have any problems in the future, just come here generously."

Chen Bing also added.

"The desk on the right is An Jiajun, a teacher of geometry and topology, who is also very easy to talk."

Su Mu nodded.

Once again, I would like to express my gratitude to the two teachers.

......

......

"By the way, teacher, can I publish my little paper here?" After chatting casually for a few more words, Su Mu asked Xiang Jun tentatively. Because he heard that Zhao Yuhui seemed to be going to publish his paper in the core journal of Peking University, Su Mu wanted to try to see if he could increase his skills and something like if he published his paper.

"Huh? Absolutely. ”

Xiang Jun nodded, and then kindly reminded:

"But I think you'd better discuss this with your mentor..."

Although this kind of thing is not explicitly stated in academics, if a graduate student publishes a paper, there must be a first author, a second author, a third author, a corresponding author, and so on.

Generally speaking, the students themselves must be the first author, and then the tutor and other teachers who give help are the second authors, plus a right of authorship, and if the help is greater, they may even be tied with the students as the first author.

Of course, some disgusting teachers will even take away the first author of the student, but basically nothing like this will happen at Peking University, and everyone still has a bottom line and a scale.

As a student in the School of Physics, Su Mu wrote a mathematical paper.

Xiang Jun felt that it was better for him to talk to his mentor to avoid estrangement.

"I don't need to sign my words, and I didn't do you much." Xiang Jun opened his mouth and said that Su Mu's thesis was very complete, and he didn't need to rub this name.

"Huh?"

Su Mu was stunned.

He's only a freshman, where did he get some mentors.

Only then did I realize that the teacher seemed to have misunderstood.

Chen Bing also reacted suddenly, his face became extremely strange, Su Mu's paper almost made him forget that Su Mu was just a freshman student!!

"Mr. Xiang, he is a freshman this year.... I was a student at the World Mathematics Olympiad. ”

"What I mentioned to you is Su Mu who won the special prize for the Olympiad."

Chen Bing explained weakly.

"New...."

When he heard the word freshman, Xiang Jun suddenly didn't realize what kind of freshman he was and which college he was from.

But when he said the Olympiad, his face suddenly became confused, and he realized that something was wrong.

"Not ????" Xiang Jun even laughed out loud in surprise. "No, no, no... Wait wait. ”

"You say he's a freshman?

"Hmm."

"Freshman graduate student??" Although Xiang Jun already had some conjectures, he still didn't dare to believe it.

"Freshman." Chen Bing explained with a wry smile.

“.......”

Xiang Jun was stunned for three or four seconds before he really reacted.

The logical student in front of him is actually the student who won the special award of the Olympiad World Mathematics Championship before??

And now I've written a graduate-level dissertation to ask myself questions???

Xiang Jun suddenly had a sense of fantasy.

But looking at Chen Bing's appearance, it is likely that what he said is true!!

Zhao Yuhui also looked like he had seen a ghost, and his expression when he looked at Su Mu was even more stunned, and he suddenly couldn't find anything to complain about for a while.

He originally wanted to say that he would wait for an opportunity to consult this powerful senior.

As a result, Su Mu was actually a freshman who was so younger than himself.

Freshman??

Is there such a scary freshman??

He suddenly regretted staying here, because Zhao Yuhui was afraid that Xiang Jun would say that even a freshman could do it so well, but he revised it back and forth so many times.

However, his worries were clearly unfounded.

Because Xiang Jun is now in the same confusion as him at this moment.

In the end, Su Mu personally opened his mouth to explain to Xiang Jun, and Xiang Jun understood the ins and outs with a stunned face, and the praise in his eyes when he looked at Su Mu was even more learned.

To be able to make such an achievement at such a young age, if he is given the opportunity to develop, Su Mu's achievements in the future will definitely not be low!! Su Mu asked the two teachers again about the publication of the paper, and Xiang Jun and Chen Bing agreed that this paper can definitely be submitted to the core journal of Peking University.

But in addition, Xiang Jun also suggested that Su Mu make an English version first and give it a try.

According to Xiang Jun's estimate, if Su Mu adds some details, there is a great possibility that the manuscript will be passed!!

Although there is a precedent for Peking University to publish SCI students in their freshman year, no matter what, it is already the absolute top level!

With the guidance of the teachers, Su Mu's mood was much smoother.

Teacher Xiang Jun also gave Su Mu his contact information, telling him that if he has any problems in the future, he can come and disturb him at any time.

Even, when Su Mu was about to leave at the end, Xiang Jun asked Su Mu several times if he had any thoughts of transferring to the hospital.

The main Su Mu wanted to transfer to the college, and he could immediately use his connections to transfer Su Mu to the School of Mathematics, and even directly let him be his graduate student.

Su Mu naturally refused.

Even Professor Chen Bing refused.

Because Professor Chen Bing said that if Su Mu came to the School of Mathematics, even if he applied for a graduate project, he would have to put Su Mu under his name.

Looking at the robbery of the two teachers and professors, Zhao Yuhui didn't even dare to happen in the end, he only felt that the gap between people was really big.

Originally, Zhao Yuhui thought that his strength was strong enough, but now compared to Su Mu, he is simply a scumbag.

.......

......

When Su Mu returned to the dormitory, the sky had already darkened, Zhuge Chuixue was writing homework in the dormitory, during this time he had settled down a lot, except for some projects in the student union, he was basically studying hard, and he rarely even played games.

Lin Shaojun was playing with his mobile phone in his seat, Su Mu's brows furrowed, Lin Shaojun played games more frequently than he imagined, almost every time Su Mu came back, Lin Shaojun was playing games.

Although it is said that when Lin Shaojun plays games, he will not be as bumpy as Zhuge Blowing Snow, but in line with the idea of thinking about his roommate, Su Mu feels that he still has to persuade him not to be too obsessed.

After thinking about it, it happened that the class was doing a poor student identification recently, so Su Mu opened his mouth and asked:

"Lin Shaojun, is your poor student's identification form ready, it's going to be handed in this weekend."

Seeing Su Mu talking to himself, Lin Shaojun was stunned, and while playing a game, he raised his head hesitantly: "I don't report poor students...."

"You don't report the poor students?" Now it was Su Mu's turn to be stunned, because he was the class leader, he still knew a little about the information of the students in the class.

Because Lin Shaojun's family conditions are not very good, the counselor even told him to take care of Lin Shaojun more.

But now, he actually said that he didn't report the poor students?

This incident even made Su Mu forget to persuade him to play less games.

"Why don't you apply, if you apply for a bursary, it will be one or two thousand yuan. With you..."Su Mu originally wanted to say that Lin Shaojun's family would definitely be able to pass, but suddenly felt that it didn't seem good to say this, so he stopped.

"It's okay.... I'll go find a part-time job when the time comes, I don't really want to apply for a poor student. ”
