Two o'clock.

Lu Zhou, dressed in a suit and leather shoes, walked up to the podium, and the lecture hall, which was originally a little noisy because of the exchange of ears, fell silent for a moment.

No one maintained discipline, everyone was very tacit, and their eyes were fixed on the person on the podium, either suspicious, expectant, or expressionless.

If it's a different person, let alone talking about math problems, I'm afraid my legs will be weak when I am stared at by so many big guys.

But Lu Zhou, who was standing on the podium, had a calm expression, and he did not have stage fright at all because of the pressure transmitted by that pair of eyes.

The mental preparation that should be done has already been made when you are offstage.

What's more, it's not the first time he's faced this kind of occasion.

"Thank you for coming from all over the world to Princeton and to hear me stand here and report on the results of the Goldbach conjecture."

As is customary, to thank the scholars who were invited to listen to the presentation, Lu Zhou began to describe the process of the presentation.

"I will divide my presentation into two parts, one on the group construction method that I used to prove the Goldbach conjecture, and the other on the proof of the Goldbach conjecture."

"I'm sure you've all read my paper before I came here. For the long and tedious steps in the paper, I will abbreviate them in the PPT. As for my explanation, it will mainly focus on the key steps and thoughts and ideas. ”

"In addition, I will devote as much time as possible to the question session."

Preparing for the presenter's paper before the start of the academic presentation is both a common practice in academia and a necessary etiquette. If it comes to the question session, the questions that stand up and ask are all written in the paper, or are inconsequential, it will be considered a very rude and unqualified thing.

For all of you here, such a problem will naturally not arise.

In the same way, there is no need to go through the PPT again for those parts that have been clearly written in the paper. After all, everyone's time is precious, and they didn't come to Princeton to watch the slides.

At the end of the opening remarks, Lu Zhou went straight to the point.

"The so-called group construction method is the abbreviation of the 'overall structure research method of group theory', and its core idea is to use the concept of cyclic group to study the problem of infinity as a whole. Based on the theorem that the multiplication group of integer modulo p is always a cyclic group, we can get the ......"

While explaining, Lu Zhou's laser pointer roamed the white curtain.

【…… Let the finite group G and |G|=p1α1p2α2··· piαi, where pi is a prime number and αi is a positive integer. Let p∈π(G), define deg(p)=|{q∈π（G）|p~q)|

Deg(p) is called the number of times the vertex p. Redefine C(G)=......]

Compared with the proof of Goldbach's conjecture in the second half, the theory of group construction is more crucial, because only by understanding the content of this part can those who sit in the lecture hall and listen to him understand what he is doing.

Therefore, Lu Zhou explained the content of this part in great detail, and explained every point as clearly as possible.

And the people sitting in the audience, whether they were invited scholars or uninvited students, listened very carefully.

James Maynard, in particular, sat in the middle of the room with his arms crossed, and listened very attentively.

As the saying goes, peers are enemies, and he is also a leader in the field of analytic number theory among the new generation of British mathematicians. As one of the popular candidates for the Philippine Award, he originally planned to use the twin prime problem to increase his 18-year Fields Medal, but he didn't want to be taken first by Lu Zhou, so he burned the manuscript in anger.

It can be said that he made a special trip from England to find fault with his competitors.

But that's what it said......

The more he looked down, the more intriguing his expression became.

The logic of this Chinese scholar is so rigorous that now he not only does not find any problems, but even can't help but applaud it......

Sitting next to him was his PhD student, also a British guy named Evan.

Looking at the lines of text flashing across the screen, the British guy gradually began to lose a little bit of his pace.

Finally, he couldn't help himself and asked in a low voice.

"Professor, what is his group construction method talking about?"

Maynard stared at the PPT meticulously and was silent.

He could answer that question, but he couldn't.

First, he didn't want to miss any details because of distractions, and second, he was afraid that as soon as he opened his mouth, he couldn't help but express his praise for this ingenious method...... And just the day before yesterday, he also threatened on his personal blog that the 50-page paper was all waste paper, and that he would expose the trick of this Chinese on the spot at the report meeting in Princeton.

However, even if he doesn't want to admit it, he now has to admit that the gap between his strength and his opponent may be separated by more than one Philippine award......

Yes or no, math is such a realistic thing.

On the other side, in the back row of the lecture hall, two old men sat in the corner of the venue in a very low-key manner, watching the report meeting and whispering in a casual tone.

"I didn't expect that I had only been away for a few years, and the Institute for Advanced Study in Princeton had another talent." Looking at the young people on the stage, Andrew Wiles nodded approvingly, "Yes, half of my demeanor back then." ”

After returning to his alma mater, Oxford, in 2011 to teach, Andrew Wiles rarely returned to the Institute for Advanced Study in Princeton. And the position of head of the mathematics department at Princeton University was given to another genius, Charles Fepferman.

And the year he was talking about was the most important lecture on mathematics at the end of the 20th century held by the Newton Institute thirteen years ago. More than 200 mathematicians listened to the lecture, even though only a quarter of them could fully read the Greek letters and equations on the blackboard.

As for the remaining three-quarters, they have traveled thousands of miles to England just to witness history.

It's the same now.

Although Goldbach's conjecture is more like an intelligence test than Fermat's theorem, which is widely used, this intelligence test can be included in the eighth question of the twenty-three questions, which shows its status in number theory and even in the field of mathematics as a whole.

Solving it may not change the world like the millennial problem, nor can it change mathematics like Fermat's theorem, but the tools created in solving this problem are invaluable to the entire mathematical community.

There is no doubt that all of us sitting here are witnessing history.

"Hehe," Deligne said mercilessly, "I don't know who it was at the beginning, with an apocalyptic expression all day long, planning to apologize to the New York Times, and preparing to return the champagne that was opened." ”

Wiles coughed lightly and lightly recounted this dark history: "Only when one is faced with a desperate situation can one drive a burst of inspiration." I'm just pushing myself into a corner, and then I'm desperate...... As far as the results are concerned, I did. ”

Deligne unceremoniously debunked: "Wasn't your last explanation performance art?" ”

"Well, my dear friend, let's change the subject," said Wiles, quietly shifting the subject, looking at the curtain, "Goldbach guesses that I don't know very well, and from your point of view, is his thesis proof?" ”

Deligne: "You should ask Ivanets and Faltins this question. They're experts in analytic number theory, and I'm just dealing with prime numbers. Of course, after reading his paper, my opinion is more optimistic. ”

If he is not optimistic, he will not arrange this report meeting for Lu Zhou, but suggest that it be revised.

Wiles' expression was surprised: "Faltins is here too?" ”

"It's not that he's coming," said Deligne after a pause, "but that no one wants to miss—"

At this moment, a small exclamation sounded in the venue.

It was an astonishing amazement.

At the same time, it also contains praise.

Deligne and Wiles stopped communicating and looked back at the stage.

After a while, Wiles smiled and said, "It seems that our worries are unnecessary. ”

Looking at the equation on the curtain, the corners of Deligne's mouth finally stretched a smile of relief.

"I've never been worried."
