"I have a meeting in the evening. You can do your own thing. If you want to go out, call Director Xue. But don't be too late. Come back early to prepare tomorrow's report!" After the meeting, Professor Zhang took him and the new executive

The directors finished their meal and then gave instructions.

"Okay, I'll just walk around the school! I won't go out!" The day's plenary meeting is over, but tonight there is still the last standing council meeting, which Professor Zhang will participate in; according to the meeting schedule,

Tomorrow night is the meeting of this session's standing committee, and I will probably participate in it then.

As a result, his plan of taking a stroll could not be carried out after all. As soon as he came out of the restaurant, someone came to chat with him. Lu Qiujian couldn't resist, so more and more people gathered at the door of the restaurant.

"Dr. Lu, I have read all your articles in the Annals of Mathematics, but I still have some doubts about the one about partial differentials!"

"Dr. Lu, tell us about your attempt to crack the Poincaré conjecture!"

"I have a newly written article here, and I would like Dr. Lu to correct me!"

Lu Qiujian glanced at them and saw that most of the people gathered around them were "young scholars" in their thirties and forties. Those who were older may have been proud of their status and did not come forward.

"Well, everyone has blocked the road to the restaurant, why don't we change places?" Since we can't go out for a walk, we simply find a quiet place to have a detailed chat. Although we have a big tree at our back, we still have an extra knot.

Good karma always has benefits.

"There is a small conference room upstairs! The chairman and the others went to the villa for a meeting and couldn't use it. I went to the hotel to tell them to use it!" Immediately, a local gangster from the school went to deal with it. After a while, he got the key.

The young scholars walked up the stairs talking and laughing.

"Hmph, a bunch of people who follow the trend!" Professor Wu came out of the restaurant and saw this scene. He couldn't help but twist his nose in anger, and reached out to grab Lao Liu behind him, "Let's go back to the room and play chess!"

Lao Liu hesitated in his steps, and said as if he was defending or mumbling to himself, "We both study low-dimensional topology. It's not easy to have such an opportunity to communicate. Why don't you come up and listen?"

When Professor Wu heard this, his heart moved, but he could not take a step forward after all. He did what he did to Lu Qiujian yesterday. Today, he couldn't get rid of his old face no matter what; so he said a little irritably, "How about you go!"

I have a headache and won’t go away!”

After speaking, he walked out quickly. Lao Liu looked at his back and shook his head. After all, he didn't chase him and followed the stairs to the small conference room upstairs.

Arriving at the conference room. As soon as everyone sat down, scholars from Jiangcheng University greeted people and brought tea and fruits. A group of people let Lu Qiujian sit at the head. At the beginning of the exchange, there was still going back and forth, but slowly

It became a pattern where everyone asked questions and Lu Qiujian answered.

"Dr. Lu, I have been studying the problem of Lie groups recently, and I have been struggling with one part for a long time. I wonder what you think about the application of Lie group theory in fluid mechanics?"

"Oh, I understand what you mean. This problem can be solved using the Boltzmann equation. You only need to give the simplification of the Boltzmann equation on s3(1)"

"Dr. Lu, I have an article about using group theory methods to solve integer programming problems. The general content is"

"On the basis of transforming and relaxing the integer programming problem, it transforms and decomposes it into a group theory programming model. The two methods for solving the decomposition results are"

Questions were asked one after another, and the scope of the questions was increasing and the depth was getting deeper and deeper. At first, when others asked questions, others could listen carefully, or frown and think hard, or be confident; but later,

There are fewer and fewer people who can think deeply after the question is raised, and most of them look at each other. Those questions are beyond the scope of their understanding. After all, there are too many branches of mathematics.

"eleven!"

"twelve!"

"Thirteen!"

A scholar next to Lao Liu would report a number after a while; huh? What is he doing? Lao Liu couldn't help but curiously asked, "What are you doing?"

"I'm counting how many branches of mathematics the questions answered by Dr. Lu involve. In just a short time, eighteen questions have been answered. They belong to thirteen different ones." Just as he was speaking, another scholar

After asking his own question, Lu Qiujian continued to answer, "Now is the nineteenth question, the fourteenth branch of mathematics!"

He couldn't help but turn around and look at Old Liu, "How old do you think he is? It's fine if he has studied a certain field deeply! Why does it seem like there is no field that he doesn't know how to do! What's going on?

Learned it?”

Old Liu was speechless and continued to listen to Lu Qiujian's answer silently.

It wasn't until almost twelve o'clock that he returned to the standard room he shared with Professor Wu. When he opened the door, he saw that Professor Wu still had the light on, "Hey, you're not asleep yet?"

"I'm too old to sleep!" Professor Wu shook his head, "Why did you come back so late? What was the gain from the exchange just now?"

"It's a worthwhile trip! It's really a worthwhile trip!" As soon as he mentioned this old Liu, he immediately became energetic, "The exchange tonight was very fruitful! These Dr. Lu don't look young, but in

His mathematical attainments are truly extraordinary."

"Oh? Tell me about it?" Professor Wu poured a cup of tea and handed it to Lao Liu.

"At first, like me, everyone thought Dr. Lu only had in-depth research on the Poincaré conjecture, but I didn't expect it was much more than that!" Old Liu said with emotion as he took the tea cup.

"What? He also does research in other fields?" Professor Wu asked with a complicated mood.

Old Liu stretched out his right hand, first raised his index finger, and then raised his thumb and index finger. "From the end of the meal to now, he has answered a total of eighteen questions in different branches of mathematics! No one who asked the questions was dissatisfied with the answers he gave."

Yes! They say that his research in this area is deeper and more thorough than mine!"

"Eighteen different branches of the problem?!" Professor Wu was as amazed as the Shaolin monks who saw Jiumozhi perform eighteen kinds of seventy-two unique skills. How did they learn such things!

This kind of emotion not only happened in the room between Lao Liu and Professor Wu, but all the scholars who participated in tonight's exchange were impressed by Lu Qiujian's overly young age and overly extensive mathematical knowledge.

Those who asked the questions wrote down the suggestions given by Lu Qiujian as soon as they returned to the room. Those who did not seize the opportunity made up their mind to ask the questions that had puzzled them for a long time tomorrow night; Lu Qiujian

Jian’s first informal appearance in front of domestic scholars was a great success. (To be continued.)
