Zhang Shouwu also managed to squeeze out of the lively crowd.

As the chairman of the subcommittee of the algebra group, as a professor at Princeton University, as a big bull in the direction of algebra, and his close students, the number of professors is second only to Mr. Qiu.

Chong Chen Zhou and Yang Yiyi smiled, and Zhang Shouwu said with a smile: "I really have something to do with you, is it convenient to talk about it alone?"

Chen Zhou glanced at Yang Yiyi, and Yang Yiyi said softly: "I'm waiting for you here." ”

Chen Zhou got up and followed Zhang Shouwu to the balcony of the banquet hall.

"That girl is your girlfriend, right?" Zhang Shouwu noticed that after Chen Zhou walked to the balcony, he also glanced inside.

"Yes. Chen Zhou withdrew his gaze from the banquet hall and nodded slightly.

"Then it's not surprising, this girl is pretty good at math. Zhang Shouwu complimented.

Chen Zhou glanced at Zhang Shouwu and thought to himself, why did this person keep trapping?

Of course, Chen Zhou just silently complained in his heart.

??“ Ahem......" Zhang Shouwu was a little embarrassed, so he turned to the topic, "During the interview, the friend I said contacted me. ”

Hearing this, Chen Zhou roughly understood what Zhang Shouwu was going to do.

However, he didn't rush to answer, but waited for Zhang Shouwu's words.

Zhang Shouwu looked at Chen Zhou and continued: "He would like to invite you to join the research group and work together on the direction of complex partial differential equations. ”

After speaking, Zhang Shouwu observed Chen Zhou's expression attentively.

In fact, before the start of the Qiu race, his friend found him and asked him to help contact Chen Zhou.

But he was skeptical.

Because, this person named Chen Zhou, he has never heard of it at all.

Later, after finding Chen Zhou's information through friends in China, he became more and more confused.

Because it is clearly written on the information, Chen Zhou has just been a freshman at Yan University.

He didn't think a freshman could complete such a piece of paper.

Because, he also read Chen Zhou's paper on Clifford's analysis, not to mention the core content and so on.

Just the choice of words and sentences, he didn't feel like a freshman could write it at all.

So, he hesitated to talk to that friend of his.

After all, the academic atmosphere in China is really not flattering.

At this time, the sixth Qiu Sai began, and he received an invitation from the Tournament Committee and Mr. Qiu Lao, hoping that he could come back for the Qiu Sai interview.

After some consideration, coupled with some special reasons, Zhang Shouwu decided to come back and test Chen Zhou's true level by the way.

The results were naturally unexpected.

Chen Zhou's performance in Qiu Sai can be said to have surprised him.

Mr. Qiu was also on the side when he was reading Chen Zhou's pen test papers.

After seeing Chen Zhou's answer, he began to believe that the paper was written by Chen Zhou.

After all, the calculations are just as rigorous.

It's a calculation with a very strong personal label.

But if anyone has understood Chen Zhou's calculations, the next time they see the calculations made by Chen Zhou, they will definitely recognize them at first sight.

As Mr. Qiu said, Chen Zhou's calculations are extremely rigorous, the logic is meticulous, and the ideas for solving are extremely clear.

Because of this, there will be those questions asked by Chen Zhou in the later interview.

Only now I am looking for Chen Zhou alone and sending out an invitation.

At least, in his opinion, Chen Zhou passed his investigation.

Chen Zhou naturally didn't know what Zhang Shouwu was thinking, and he groaned slightly.

If Chen Zhou could receive such an invitation earlier, he would definitely be extremely happy.

But now, he has made the hail conjecture his research topic, and he has spent so much time.

If you want him to change the subject halfway, how is that possible.

Eventually, Chen Zhou said, "I'm sorry, Professor Zhang, thank you and your friends for your kindness. Although I am still interested in the direction of complex partial differential equations, I really don't have more time now, and I am afraid that I will not be able to join this group. ”

Zhang Shouwu was slightly stunned, and then smiled softly: "It's okay, I will tell him what you mean." ”

Chen Zhou smiled slightly: "Thank you for your understanding." ”

After a pause, Chen Zhou asked curiously, "Is that friend of yours the editor of the Journal of Function Analysis?"

Zhang Shouwu shook his head and said, "It's not an editor, it's an external reviewer, and I was invited by "Function Analysis". He was so impressed with your calculations in the paper that he asked me to contact you. ”

Chen Zhou now understands that it seems that his paper can be published so quickly, mainly because his calculations are more powerful.

However, having already rejected other people's invitations, it is difficult for Chen Zhou to ask the other party's identity anymore.

Zhang Shouwu did not continue to dwell on this topic, and instead chatted with Chen Zhou about the field of algebra that he is good at.

The content of the talk is not very profound, it is all something that can be discussed with Chen Zhou.

Chen Zhou also found out at this time that this Professor Zhang was quite approachable.

And for the content in the field of algebra, some of his insights gave Chen Zhou a refreshing feeling.

Sure enough, the reason why the big bull became a big bull is not unreasonable.

This insight alone is not something that ordinary people can understand.

But what Chen Zhou didn't know was that as the two talked, Zhang Shouwu became more and more surprised.

The student in front of me, who is only a freshman, has an extraordinary understanding of mathematics and is familiar with mathematical knowledge.

Even in some places, it is deeper than the understanding of some graduate students.

Zhang Shouwu suddenly had a thought, he looked at Chen Zhou and asked, "When do you plan to go out of Yan University?"

Chen Zhou was also frank: "Let's end my sophomore year." ”

Zhang Shouwu said strangely: "Sophomore, it won't take that long, right?"

Chen Zhou explained with a smile: "Well, generally speaking, it doesn't take that long. However, I also plan to minor in physics. ”

Zhang Shouwu was stunned for a moment, and looked at Chen Zhou a little strangely: "You shouldn't study mathematics to study physics, right?"

Chen Zhou shook his head: "No, isn't mathematics the study of all other disciplines?"

Zhang Shouwu: "......"

Chen Zhou glanced at the banquet hall again at this time, and almost all the people at their table had returned.

"Ahem...... Zhang Shouwu coughed lightly twice, and said simply, "Are you going to come to Princeton?" ”

Chen Zhou looked at Professor Zhang beside him, this was his second invitation tonight, and it didn't seem good to refuse directly......

Moreover, if other students heard Zhang Shouwu's invitation, I am afraid that they would have been busy agreeing a long time ago.

It's just that Chen Zhou thought about it and said: "Princeton is indeed a good place to study mathematics, but thank you for your kindness, I haven't thought about it yet." ”

Zhang Shouwu said with a little regret: "Okay, if you plan to come to Princeton, you can contact me in advance, and I will try my best to help." ”

Chen Zhou said gratefully: "Thank you." ”

Chen Zhou noticed that Yang Yiyi was waving at him, and seemed to have something to look for him.

He said hello to Zhang Shouwu and prepared to go back.

Zhang Shouwu nodded slightly, then thought of something, and said loudly: "Chen Zhou, it's convenient to say, what have you been studying recently?"

After speaking, Zhang Shouwu added: "It's purely personal curiosity." ”

Chen Zhou thought for a moment and said softly, "Hail conjecture." ”

Zhang Shouwu: "???"
