Liang Qiushi was stunned.
Xiao Yi's expression remained the same.
I quickly finished reading the paper brought by Liang Qiushi. Although it has more than forty pages, it does not require much effort for Xiao Yi.
After all, after Liang Qiushi just told him his idea, he already knew how to solve this problem, not to mention that Liang Qiushi came to him to ask about the method some time ago.
After Liang Qiushi went back, he quickly solved the problem that stumped him according to Xiao Yi's guidance. At the same time, he also read the paper recommended to him by Xiao Yi. After reading it, Liang Qiushi had an idea about the non-homogeneous Baker-Sprindzuk conjecture he had encountered.
This non-homogeneous Baker-Sprindzuk conjecture itself is not very difficult. After Liang Qiushi had studied the subject to that extent, it was no longer far away from solving this conjecture. After a simple study, it was successfully solved.
Therefore, when Xiao Yi looked at his paper, he only needed to look at a few key points and was basically sure that there was no problem with his paper.
As a mathematical paper, the originality of this paper goes without saying. It successfully extended the non-homogeneous Diophantine approximation method on Real Domain to the function domain, and also successfully proved the non-homogeneous Baker-Sprindzuk conjecture in the process. As a novel result, the innovation is enough.
In terms of the most important rigor of mathematics, the logical structure is rigorous, the argumentation process is clear, accurate, and complete, and there are no logical loopholes or errors; definitions, assumptions, conditions, etc. are clearly given, and the necessary lemmas and theorems have strict mathematical proofs, and no problems can be found.
Therefore, Xiao Yi made the final comment. "Very good. Your paper has met my expectations for you. Of course, it has also met the graduation requirements."
"Then... congratulations."
Xiao Yi put down the paper with a smile and congratulated Liang Qiushi.
Liang Qiushi At this time, he had recovered from the shock, and then he smiled and said, "Thank you for the teacher's guidance!"
Xiao Yi shook his head with a smile and said, "Don't thank me in a hurry. Check all the formats as soon as possible after you go back, and then upload them to the website. I will invite a few more experts to listen to your defense next month. They will not give me face by then."
"It depends on your own abilities, kid."
Liang Qiushi was not timid at all, he waved his hand directly and said, "You can shout whatever you want, I will guarantee that I will take it down easily."
"That's it." Xiao Yi nodded with a smile.
"But..." Liang Qiushi suddenly said, "I can't be the only one like this, right? Chen Muhua, and Sun Yuan, they should also be like this, right?"
Xiao Yi rolled his eyes and said, "You kid still wants to enjoy it alone, don't worry, they are indispensable."
"That's good!" Liang Qiushi nodded happily.
"Then teacher, I'm going to leave first?"
Xiao Yi nodded. "Okay, go ahead."
However, after a while, the two of them said together, "Wait a minute."
Both of them were startled, and then Xiao Yi asked, "What else do you want?"
Liang Qiushi scratched his head, pointed to the paper by Xiao Yi, and asked, "Teacher, when can I see this paper of yours?"
Xiao Yi said, "You can see it tonight."
Liang Qiushi nodded and smiled, "Then I'm just waiting to see how Hailstone Conjecture solved it."
"Just wait and see."
Xiao Yi just smiled lightly, and then asked, "But, I heard that you are getting married soon?"
"Ah!" Liang Qiushi was stunned and said repeatedly, "Yes, teacher, I originally planned to tell you later, but I didn't expect you to know now."
"It wasn't that guy Chen Muhua who told you, was it?"
Xiao Yi smiled and said, "This has nothing to do with Chen Muhua. But don't forget, I am still a teacher at the School of Physics. Your girlfriend has already told her teacher, and Professor Liu from the School of Physics just told me about this matter two days ago."
When Liang Qiushi first entered school a few years ago, Xiao Yi asked why he would apply here with his grades. After all, based on Liang Qiushi's undergraduate performance, it would be no problem to apply for MIT, Princeton University, etc.
Then I learned that he was chasing his girlfriend.
His girlfriend's name is Chen Chunhua, which matches his name very well.
The relationship between them has probably always been very good, otherwise they wouldn't have planned to get married by now.
"So that's it."
Liang Qiushi then realized this and shook his head helplessly. Since it was his fiancée who revealed it, he could only be angry and had nothing to do. He could only say that his teacher was well-informed.
Then he said, "Yes, the wedding day is set for August 8 this year, which happens to be the Chinese Valentine's Day."
Xiao Yi smiled and nodded, "Yes, very good."
Liang Qiushi also had a happy smile on his face.
He and his girlfriend were not childhood sweethearts, they just met in college.
There are so few cases of childhood sweethearts being admitted to the same top university together, and being able to secure graduate degrees together, and it even feels unreal.
But until now, they have known each other for almost seven years. Now being able to get married means that they have overcome the test and ushered in victory in these seven years.
"It's just that the wedding won't be held at Fei City by then, and will go back to my hometown." Liang Qiushi said, "I will definitely send an invitation letter to the teacher by then, whether he comes or not."
Xiao Yi knows that Liang Qiushi's hometown is in E Province, Jiang City, and the two provinces can be considered neighboring provinces, but getting to Jiangcheng City from Fei City is not as close as to Jinling.
What's more, thinking about it, he didn't have much reason to go to Jiangcheng City.
In the end, he could only nod and said, "Okay, even if I can't go, I will give you a red envelope."
Liang Qiushi just smiled and said, "That's a good relationship! Then when you have the teacher's wedding banquet, I will definitely give it to you."
"I just don't know, does the teacher have a partner now?"
Xiao Yi immediately waved his hand and said, "You don't need to worry about this anymore. Let's go quickly."
Liang Qiushi chuckled and then quickly slipped away.
"Tsk tsk..."
Seeing Liang Qiushi close the office door, Xiao Yi sighed with emotion.
Time waits for no one, even his own students are getting married.
As for himself?
"Don't think about this, the paper is not finished yet."
Then Xiao Yi continued to write the paper.
Until the evening, when the paper is sorted out, others may still care about the font format, but he doesn't need to care at all.
It's a personal website anyway, so you can do whatever you want.
So, he immediately uploaded the paper directly to the Internet.
After finishing this matter, I looked at the time, but it was already too late, so Xiao Yi didn't stay any longer, contacted Wang Li to get in the car, and then went back to rest.
Perhaps Xiao Yi has not uploaded a paper on his website for a long time. For a while, the paper was not discovered immediately after it was uploaded.
Probably because it was late, most people had already taken a break. Even those self-media who insisted on logging in to the website every day to see if they could see any "surprises" had stopped working at this time.
As for people from abroad, they won't log on to Xiao Yi's website with nothing to do. Therefore, every time there is a new paper on Xiao Yi's personal website, the news usually comes from China first.
However, if the self-media does not read it, other people will.
And this person is Liang Qiushi who got the "insider information".
Because he had completed his thesis, he was quite happy that night and was ready to have fun with his fiancée, who was about to enter the palace in a few months.
While he was singing in a KTV, he suddenly slapped his head, took out his mobile phone, and logged into his mentor's personal website. Then he saw a brand new paper appear on the website.
The name of the paper is very simple, it is called "Hailstone Conjecture", and it is published in Chinese and English.
He immediately slapped his thigh and said "fuck".
Seeing his excitement, his girlfriend next to him also stopped singing and asked, "What's wrong?"
"Look, my teacher's personal website."
"Professor Xiao?"
Knowing that it was related to Xiao Yi, my girlfriend also became curious.
Back then, she was also a student who tried to apply for Xiao Yi, but failed in the end. Of course, she would not have any complaints about this. Anyway, there were countless students who applied for Xiao Yi. Compared with other people, she did not have many advantages.
However, it did not prevent her from being interested in Professor Xiao.
After all, she studies nuclear physics, and Xiao Yi has solved one of their biggest problems in nuclear physics - how to achieve controllable nuclear fusion power generation.
Therefore, none of them who studies nuclear physics does not admire Xiao Yi.
In other words, Xiao Yi will not start classes in their physics school, otherwise, the threshold may be broken.
"Look at this paper, it is the latest achievement of my mentor."
Liang Qiushi Show it to your girlfriend.
My girlfriend was stunned. "Hailstone Conjecture? Is this another mathematical conjecture? Similar to Goldbach Conjecture?"
"Yes, you should have heard of this conjecture. It's written in elementary school textbooks."
Then, Liang Qiushi introduced to his girlfriend what Hailstone Conjecture looked like.
After some understanding, his girlfriend naturally didn't know how difficult this problem was. After all, she didn't specialize in mathematics, but she just didn't know how difficult it was.
Especially knowing that this problem has not been solved for decades, and former mathematics masters also said that the mathematics community is not ready to face such a problem.
"Professor Xiao is so amazing!" his girlfriend sighed with emotion.
"Of course!" Liang Qiushi had an expression that said, "It's up to you to say that." Then he began to share this matter with various groups he had added.
In order to spread this important matter to more people.
In the world of mathematics, another difficult mathematical conjecture has been solved.
"Humph, this is my first-hand information, isn't it great? I saw it when I went to the teacher's office at noon today and reported to him the completion of the thesis." Liang Qiushi showed off in front of his girlfriend.
"It's awesome." My girlfriend smiled and said, "Then can you be as awesome as Professor Xiao in the future?"
As soon as I heard this question, Liang Qiushi was stunned.
"There is no pot that cannot be lifted. My mentor is simply not something that humans can surpass."
His girlfriend laughed, and then handed the microphone to him again. "Okay, now let's continue singing. As we keep singing, maybe you will become as good as Professor Xiao."
"Okay, okay." Liang Qiushi naturally didn't believe such a thing existed, but he took the microphone and started singing a love song with his girlfriend.
"Sister, you sit on the bow of the boat~Brother is walking on the shore..."
Liang Qiushi has joined a lot of groups, and naturally posted a lot of groups, including some in mathematics.
So not long after, the topic of [Chief Designer Xiao solved Hailstone Conjecture] spread directly in the domestic mathematics circle.
Domestic mathematics scholars or students were immediately shocked.
For example, in one of the groups called [China Mathematical Society Exchange Group] added by Liang Qiushi, related discussions immediately broke out.
As the name suggests, this group was naturally organized by the Chinese Mathematical Association. Liang Qiushi had previously participated in an academic conference, and then others learned that he was a student of Xiao Yi, so they invited him in.
Now, Liang Qiushi naturally posted the message in this group, and immediately, a lot of people appeared in this group.
[ah? Real or fake? Professor Xiao took care of Hailstone Conjecture again?]
[It's true, you can see it on Professor Xiao's personal website! (Screenshot. jpg)]
After seeing someone actually post a screenshot of Xiao Yi's personal website, they immediately became even more excited.
[I am super! I also saw it, it's true, Professor Xiao is awesome!]
[I have downloaded the paper, Wo Ri, it turns out to be true!]
[No, Chief Designer Xiao just developed controllable nuclear fusion not long ago, right? It's only been a few months, and then you got Hailstone Conjecture by the way? How did he do it?]
[Look, I asked again, it's still rare and strange.]
[After reading it, there are more than sixty pages in total. I don't know if Professor Xiao has really succeeded in proving it.]
[Just kidding, Professor Xiao has published a paper, do you think it is really proved? Especially take another look at this summary.]
As he said this, a screenshot of the abstract of the paper was posted in the group.
The abstract is simple and straightforward: This paper uses Representation Theory to transform Hailstone Conjecture into an inequality problem about the invariant vector dimension in the representation space. By establishing a recursive formula for dimensions and using the properties of vector spaces, it was proved that there is a unified upper bound for the dimensions of invariant vector spaces, thus deducing the finiteness of the hail sequence periodic orbit classification tree and completing the proof of Hailstone Conjecture.
Afterwards, everyone in the group began to speculate on how Xiao Yi completed the proof.
Soon, however, they gave up.
Representation Theory?
Inequality problem with constant vector dimensions?
Hail sequence periodic orbit classification tree?
These are completely new fields and terms for the research of Hailstone Conjecture, so those who want to deduce the proof process of Xiao Yi through abstracts completely give up.
[No, Scholar Xiao What kind of proof is this? Prove Hailstone Conjecture from Representation Theory? Can this thing really be done?]
[I really don't understand something. Scholar Xiao's thinking is always different from ours.]
[...]
During the discussion among many mathematics scholars in this group, more and more people have learned about this important event.
Naturally, the news eventually spread abroad.
The international mathematics community is going to be lively again.
