"I still have a meeting in the evening, you can do your own activities, if you want to go out for a walk, call Director Xue, but don't be too late, come back early and prepare for tomorrow's report!" After the meeting, Professor Zhang took him and the new executive directors to eat and then admonished.

"Okay, I'll just walk around the school! Don't go out!" The plenary meeting during the day is over, but tonight there is the previous session of the Standing Council, which Professor Zhang is going to attend; according to the meeting arrangement, tomorrow night will be the current session of the Standing Council, and I am expected to participate in it by then.

As a result, his plan to take a stroll was not implemented after all, and someone came to talk to him immediately after coming out of the restaurant, and Lu Qiujian couldn't shirk it, so more and more people gathered at the door of the restaurant.

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

"Dr. Lu, tell us about your debunking of the Poincaré conjecture!"

"I have a new article here, and I would like to ask Dr. Lu to correct it!"

Lu Qiujian glanced at it, and most of the people around him were "young scholars" in their thirties and forties, and those who were older may have not stepped forward because of their own identity.

"Well, everyone has blocked the road to the restaurant, should we change places?" Since there is no way to go out, just find a quiet place to communicate in detail.

"There's a small conference room upstairs! The chairman of the board of directors went to the villa for a meeting, and they didn't need it, so I went to the hotel and told them to use it!" Immediately, the head snake of the university went to deal with it, and after a while, he got the key, and a group of young scholars walked up the stairs with a smile and a smile.

"Hmph, a group of people who tend to be inflammatory!" Professor Wu came out of the restaurant and saw this scene, he couldn't help but tilt his nose angrily, and reached out to grab Lao Liu behind him, "Let's go, let's go back to the room and play chess!"

Lao Liu's pace was a little hesitant. As if to justify, he muttered to himself, "We both study low-dimensional topology, and it's not easy to have such an opportunity to communicate, why don't you go up and listen?"

Professor Wu's heart moved when he heard this, but he couldn't take a step after all, he treated Lu Qiujian like yesterday, and today he couldn't pull off his old face no matter what, so he said with a little irritation, "Why don't you go! I don't go if I have a headache!"

After saying that, he walked out quickly, Lao Liu looked at his back and shook his head, but he didn't chase after him. I also went down the stairs to the small conference room upstairs.

When they arrived at the conference room, as soon as everyone sat down, a scholar from Jiangcheng University beckoned someone to bring tea and fruits, and a group of people let Lu Qiujian sit at the top; at the beginning of the exchange, there were still contacts, but slowly it became a pattern of everyone asking questions and Lu Qiujian answering.

"Dr. Lu, I have been studying Li Qun's problem recently, and there is a place that I have been entangled in for a long time, I don't know what you think about the application of Li Qun's theory in fluid mechanics?"

"Oh. I see what you mean, this problem can be solved with the Bulzmann equation, you just need to give a simplification of the Bolzmann equation on s3(1)"

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

"On the basis of transformation and relaxation of integer programming problems, the transformation and decomposition of group theory programming models are carried out, and the two decomposition results are solved by "

One question after another was raised, and the scope and depth of the questions became more and more in-depth. At first, when others ask questions, others can listen carefully, or frown and think about them, but later, there are fewer and fewer people who can think about the questions after they are asked. Most of them look at each other, and those problems 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 was about to report a number after a while; hmm? What is this doing? Lao Liu couldn't help but ask curiously, "Are you here?"

"I'm counting how many branches of mathematics are involved in the question that Dr. Lu answered, and I have already answered eighteen questions in just a few years, which belong to thirteen different ones" Just as he spoke, another scholar finished asking his own question, and Lu Qiujian continued to answer, "Now it's the nineteenth question, the fourteenth branch of mathematics!"

He couldn't help but look back at Lao Liu, "How old do you say he is? If he has studied a certain field quite deeply, it's just that! Why does it seem that there is no field that he doesn't know now! How did he learn this?"

Lao 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 shared with Professor Wu, and when he opened the door, he saw that Professor Wu was still on the light, "Yo, haven't slept yet?"

"I can't sleep when I'm old!" Professor Wu shook his head, "Why did you come back so late?

"It's worth it! It's really worth it!" As soon as he said this, Lao Liu immediately became energetic, "This exchange tonight has been very fruitful! These Dr. Lu don't look young, but their attainments in mathematics are really extraordinary. ”

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

"At first, everyone thought that Dr. Lu was just doing in-depth research on the Poincaré conjecture, but I didn't expect it to be much more than that!" Lao Liu took the teacup and said with emotion.

"What, he also has research in other fields?" Professor Wu asked with mixed feelings.

Lao Liu stretched out his right hand, first raised his index finger, and then cocked his thumb and index finger, "From the end of the meal to the present, he has answered a total of 18 questions in different branches of mathematics! None of the answers he gave were not satisfactory to anyone who asked the question! They all said that his research in this area was more in-depth and thorough than his own!"

"The problem of eighteen different branches?!" Professor Wu's amazement at the moment was no less than seeing the monks of Shaolin Temple who performed eighteen kinds of seventy-two stunts by Gu Mozhi, how did they learn this special thing!

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

Those who had asked questions had written down the advice given by Lü Qiujian as soon as they returned to their rooms, and those who had not seized the opportunity had made up their minds to ask the questions that had puzzled them for a long time tomorrow night, no matter what.
