In the auditorium of Negative Dan University, Xu Ning stood on the podium and talked.
“...... If we start from any ring on the sphere, we can slide it to a point, and when we do this, we call the ring 'equal to 0', because the ring can then become a point..."
Offstage.
Schultz and Professor Faltins, among others, are listening carefully.
Although they have understood Xu Ning's manuscript in the past two days, they basically have no doubts about the E8 manifold.
But it's not that you don't have to listen without doubt.
What they needed was Xu Ning's train of thought.
They wanted to know how Xu Ning thought when deriving the transformation of the Hodge conjecture in topological space, and how he shaped the E8 manifold in his mind.
These problem-solving ideas and ways of thinking are very informative for these top mathematicians.
Except for Schultz and others, although most mathematicians have seen Xu Ning's derivation process and generally understand it, they actually have more or less doubts.
They listened most seriously on the spot, because they could take this opportunity to listen carefully to Xu Ning's review.
As for those students....
"What is Xu Ning talking about?"
"Why is it that as soon as I bow my head and look up, the part is finished, I still haven't understood it!"
"Big guy, what is called 'deduced from this', 'obvious', we really don't know how you pushed it out, can you explain it in detail?!"
They are calm on the surface, and some people even take notes in a similar way, but in fact, they have long begun to shout in their hearts.
But they also understood that it was not that Xu Ning was not clear, but that their academic level really could not understand what Xu Ning said.
It's like a first-grader who insists on going to college to listen to advanced mathematics.
Isn't this pure abuse?
Of course, they are much better than the audience in the live broadcast room.
After all, they all have some mathematical foundation, but most of the audience is watching a lively one, and many of them are not mathematics majors.
So....
- [Abba Abba, Macabaka~].
——[When I saw Xu Ning speaking so seriously and the teachers and students in the audience listening so seriously, I had a deep sense of guilt and pain caused by ignorance in my heart~].
——[Laughing to death, you don't really want to understand what Xu Ning said, do you know what is called the Hodge conjecture, there is a random academic term in it, we can't understand, so give up! ]
——[Alas, I suddenly have an urge to study well, but when I look in the mirror, I am thirty, study? Learn a fart! ]
——[What Xu Ning said made me deeply understand that there is a big difference between geniuses and ordinary people, and even I think we are not talking a language, he is talking about mathematics, I am talking about lying groove! ] ]
On the podium, Xu Ning spoke for almost an hour before finishing the E8 manifold.
This is still his deliberate speed, otherwise, two to three hours will not be able to stop.
After speaking, Xu Ning said: "If you have any doubts, you can raise your hand and ask me questions." "
No one raised their hands in the student area, but more than twenty scholars in the front row raised their hands.
Xu Ning nodded one by one and answered their questions one by one.
Time passes like water.
After most of the questions were answered, the hour hand finally came to the number 12.
At the end of the morning meeting, everyone went to lunch either in groups or alone.
The meeting resumed at 2.30 p.m.
It was still Xu Ning who came to the stage, who added and answered the questions that had been mentioned in the morning, and then began to tell the process of proving the Koratz conjecture.
This is the request of many scholars.
They really couldn't wait for the Annals of Mathematics, and Xu Ning's paper proving Koratz's conjecture had not been published to this day.
This time, everyone came to the negative dan, just to listen to Xu Ning himself tell the proof process of the Koratz conjecture.
After a whole afternoon, Xu Ning finished the derivation process of the Koratz conjecture.
The reason why it took so long is not because the Korats conjecture is more complex than the E8 manifold, but that everyone has not seen the proof process of Xu Ning's Kolatz conjecture before.
So Xu Ning needs to be more detailed and slow.
When it was dark, the scholars present finally stopped raising their hands to ask questions.
The first day of the meeting was successfully concluded.
Well, only Xu Ning's first day on stage was over.
In the next two days, some other mathematicians shared their academic discoveries and experiences, and Xu Ning only needed to be an audience.
That evening, Xu Ning, Professor Qiu Chengtong, Professor Faltins and others went to a restaurant together.
While waiting for the dish, Professor Faltins couldn't help but say: "Xu, your talent in mathematics is the only thing I have seen, I don't know if you are interested in teaching at Princeton, I think you can get the best academic environment there, so as to perfectly display your talents and talents." "
Schultz glanced at Professor Faltins and said with a smile: "In fact, the University of Bonn is not bad, if Xu Ning is interested, you can also consider it." "
Professor Qiu Chengtong did not speak, because although it was only a brief contact, he felt that Xu Ning did not look like a person who reneged
Since Xu Ning agreed to take office, he will definitely not consider going to other schools in a short period of time.
Even if Princeton is known as a mecca for mathematical researchers?
Things did go as he expected.
Xu Ning didn't think much about it, and replied directly: "Thank you for your kindness, I don't want to go abroad at present, I just want to stay in Negative Dan to teach." "
"Okay, I respect your choice, but if you change your mind and want to come to Princeton in the future, I can help you contact the school, I think they will be happy to see you join."
Professor Faltins was not annoyed by the rejection, but said calmly.
Xu Ning smiled, "Let's talk about future things in the future, who knows what will happen after that..."
