"Let me introduce you to Xu Yun. This is Professor Tang's old friend Zhang Yitang. He came back from overseas specifically to see you." As soon as Qin Xiangxin walked to the door, his cheerful voice reached his ears. .
Xu Yun stood up and looked toward the door. His eyes passed over Qin Xiangxin and Tang Gucong and landed on Zhang Yitang.
When the other person is near, take the initiative to say hello.
"professor Zhang."
At the same time, a question mark slowly emerged in my mind?
What is the other party looking for?
Since you have studied number theory, it is impossible not to know Zhang Yitang.
In particular, the label of late bloomer attached to the other party is even talked about in the academic circles.
Although there has been no progress in twin prime numbers for many years, Zhang Yitang was able to achieve a major breakthrough in this number theory problem with one paper, which is indeed worthy of the respect of the mathematics community.
When he was studying number theory before, he also read this paper to help him understand.
But I never expected to meet in this way.
Just as he was secretly thinking about the other party's purpose and what he thought of, the other party's voice suddenly sounded in his ears.
"A genius boy in mathematics."
"Hello."
Seeing that the other party was so formal, Xu Yun did not dare to hesitate and quickly stretched out his hand to shake the other party's hand.
"Take a seat first, professors."
Although he was a junior in front of the few people in front of him, as a host, it was not good for the guests to take the initiative, so he immediately moved chairs and invited a few people to sit down.
Qin Xiangxin, who was next to him, took advantage of the situation and said, "You guys, please don't be formal. Just treat yourself as if you were in your own office."
"Xu Yun is right, let's sit down and talk slowly." Tang Gucong agreed.
After everyone was seated, Xu Yun poured a few more glasses of water before sitting down next to him.
Then they chatted with each other and said some polite words. In short, it was the so-called business flattery.
Xu Yun was quite happy with this. Since the other party didn't mention business first to express his intention, he would definitely not take the initiative to bring up the topic.
"One of you is a late bloomer and the other is a young genius. You should really communicate more." At this time, Yu Gucong took advantage of the end of the brief chat between Zhang Yitang and Xu Yun and said this half-jokingly with a smile on his face.
Perhaps seeing that the topic was a bit dry, Qin Xiangxin simply took the initiative to ask.
"I wonder what the main reason for Professor Zhang coming back this time is?" He got straight to the point.
Zhang Yitang was a little embarrassed at first, so he didn't express his intentions for a long time, but now he responded to Qin Xiangxin's words.
"It's true."
"Actually, I was mainly interested in the paper that proved the existence of infinite prime numbers in the Fibonacci sequence."
"I want to discuss some issues with Xu Yun."
When he expressed his intention, his eyes always fell on Xu Yun. It was obvious that these words were actually addressed to Xu Yun.
Xu Yun thought that the other party had been engaged in the research of twin prime numbers, and he basically guessed the other party's purpose. He really didn't expect that someone would actually come all the way from overseas to urge the update offline.
You see what this is called.
Just when he was about to inform the other party that the paper had not yet been written, Zhang Yitang took the lead in making his request.
"Can I see the manuscript of your thesis?"
"manuscript?"
Xu Yun felt a little surprised.
He thought the other party wanted to urge him to update his paper on topological group theory, but he didn't expect that he just wanted to see the content of his draft.
He did use a lot of draft paper when he demonstrated topological group theory before. After the paper was completed, he put away these drafts. Thinking about it carefully, it is indeed easier to understand topological group theory by studying the draft than the paper.
After confirming that the other party was not here to remind him of the change, Xu Yun breathed a sigh of relief and immediately stood up and walked towards the desk.
"Professor Zhang, wait a moment."
"I'll get it."
In the meantime, he did not forget to respond generously.
Zhang Yitang uttered two words relatively calmly when he heard this.
"Not urgent."
But if you look closely, you will find that his eyes are always on Xu Yun, which shows that he is still quite excited.
Soon Xu Yun took out all the drafts and walked back to Zhang Yitang with a slightly embarrassed look on his face.
"The order of that draft may be a little out of order, and I'm afraid it will look difficult."
Compared with others who deliberately organized their drafts, Xu Yun seemed very casual in this regard. In addition, when he went into the school doctor's office that day after the effect of the energy potion, his classmates helped collect the things, so many drafts would inevitably be mixed together.
On the other hand, Zhang Yitang didn't care about this. He reached out to take it and couldn't wait to check it out.
"It doesn't matter."
It is no exaggeration to say that it takes almost a few breaths to be immersed in it, which is almost comparable to the effect of concentration.
It can be seen from this that Zhang Yitang really loves number theory very much.
Because there was a lot of content in the draft, it would take a lot of time to read it all. Qin Xiangxin and Tang Gucong got up and wandered aside, with Xu Yun naturally accompanying them.
At this time, out of the corner of his eye, Yugucong glanced at a book in English on the table, with a little surprise on his face.
"Eh~"
"Are you still reading this book?"
The English translation on the cover of the book is Pattern Recognition and Machine Learning. He also knew something about it and knew that it was a relevant textbook for relevant majors in the Institute of Engineering.
That's why I was puzzled when Xu Yun read this book.
At present, the entire number theory community is waiting for Xu Yun to publish his paper on topological group theory. In his opinion, Xu Yun should concentrate on research, perfect topological group theory as soon as possible and make a major contribution to the development of number theory. However, Xu Yun instead studied Pick up computer related stuff.
Xu Yun did not hide anything when facing Tang Gucong's question, and answered directly and truthfully: "I have been studying artificial intelligence and machine learning recently."
After hearing this, Qin Xiangxin, who was next to him, also echoed: "In addition to being a member of our Institute for Advanced Study, Xu Yun is also a graduate student of the president." He introduced Xu Yun's two identities to Tang Gucong.
Tang Gucong naturally knows the field of Wu Zhongping's research, and also understands that learning computers with a mathematical foundation will get twice the result with half the effort.
But thinking about the topological group theory proposed by Xu Yun, I couldn't help but ask more questions.
"What about your research on topological group theory? Is the number theory community waiting for you?"
Xu Yun really didn't expect to avoid Zhang Yitang, and Tang Gucong was watching, and they would give him a face-to-face reminder no matter what.
Although I felt a bit dumbfounded in my heart, I still responded: "There is still a lot of room for improvement in the research of topological group theory, which cannot be solved in a short time. I also want to study other things to consolidate myself." Yutani couldn't find it. reasons for rebuttal.
After a while, it turned into a sigh.
"What you said makes sense. Matters in mathematical research cannot be solved by time."
yes.
Nothing comes naturally in mathematics.
No matter how well you master the basic knowledge, if you lack that inspiration, you still won't be able to achieve a qualitative change.
As Zhang Yitang's old friend for many years, he feels this deeply.
Otherwise, the other party would not have written the paper that promoted the progress of twin prime numbers until he was middle-aged.
It wasn't until lunchtime that Zhang Yitang looked away from the pile of draft paper.
He rearranged it, stood up and moved his body, and then walked up to Xu Yun without concealing the heat in his eyes.
"Your understanding of number theory is already higher than mine. This topological group theory is indeed amazing."
"If the famous conjecture of number theory can be completely solved, I believe this person must be you."
After Zhang Yitang roughly read the argumentation process on the draft paper, he was completely impressed by Xu Yun's genius thinking. At this moment, he put aside the age gap between the two people and expressed himself in a tone like a friend and confidant. Expectations for Xu Yun.
Although he had a high opinion of Xu Yun's paper before returning to China, he did not believe that topological group theory alone could solve number theory problems.
Even on the phone with Yutani Satoshi, he maintained a conservative attitude.
After all, number theory problems, as difficult problems in world mathematics, have troubled the mathematics community for too many years since they were proposed.
It's not that easy to solve.
But today, through the argumentation process on the draft paper, he had a new understanding of the proof method proposed by Xu Yun. Perhaps with the improvement and optimization of this method, it might be possible to use it to prove number theory problems.
After all, the bridge to the highest palace of number theory has appeared, and sooner or later mathematicians will walk in.
Xu Yun did not expect that Zhang Yitang would suddenly give him such a high evaluation, which made Tang Gucong and Qin Xiangxin beside him fall into ecstasy. I am afraid that at this moment, they were already thinking about the scene where the number theory problem was solved by the Chinese.
But Xu Yun is very clear that he still has a long way to go before this step.
Especially without turning on brain overclocking.
After all, the proof process of Hodge's conjecture is the product of random rewards, which is different from the topological group theory he created on his own.
"Thank you Professor Zhang for giving me such a high evaluation, but topological group theory still needs to be continuously improved."
"I don't dare to be too ambitious and overconfident."
With a faint smile on his face, he responded in a more humble tone.
This sentence also doubled Zhang Yitang's favorable impression, and he felt like he had been friends with Xu Yun for many years.
Next, the request was made again.
"There are also some areas where I need to ask you for advice. This may be helpful to my research on twin prime numbers."
"Of course." Xu Yun agreed generously.
However, as soon as the two of them finished speaking, they were interrupted by Qin Xiangxin next to them.
"If you have any questions, let's discuss them in the afternoon. We've been busy all morning and it's time to eat."
"Dean Qin is right, let's go eat first." Tang Gucong nodded in agreement.
Previously, Zhang Yitang had been immersed in the draft and temporarily forgot about eating and didn't feel hungry at all. Now that he was reminded by the two people, his stomach started to grow.
You must know that using your brain consumes a lot of energy.
So the few of them went to the restaurant first and agreed to discuss number theory related knowledge in the afternoon after eating.
Xu Yun naturally had no objection to this.
In this way, he spent the entire afternoon discussing and communicating with Zhang Yitang. It can be said that both parties benefited a lot.
After Zhang Yitang left, Xu Yun's life got back on track.
In addition to staying in the High School to study algorithms and sort out mathematics, I also went to Wu Zhongping on the old campus to ask for advice on programming and architecture issues in artificial intelligence.
Just as Xu Yun was thinking about the first project he would participate in as a graduate student, Zhou Zhi suddenly called him over.
