Chapter 273

Simon and Carl are at arm's edge.

Gu Lu glanced at Simon and then at Carl, confused.

Seeing Carl leaving, Gu Lu whispered to Simon and asked, "You had a holiday with Carl?"

Simon nodded, and said, "It's not just me who contradicts him, to be precise, it's our holidays at the University of Bonn and the University of Cambridge. ”

As soon as he heard that it was a private matter between the two universities, Gu Lu didn't ask any more.

"I went up and prepared in advance. ”

At 7:50, Simon pointed to the table and said to Gu Lu.

At eight o'clock, Simon was going to begin his 45-minute presentation.

And Gu Lu's report on today's meeting was placed in today's finale.

Simon and Gu Lu reported two games, one was placed at the opening and the other was placed at the finale.

I have to say that this arrangement of the International Mathematical Union is quite scheming.

Simon walked up to the stage and briefly tested the equipment.

At eight o'clock sharp, the 45-minute meeting report officially began.

The host first introduced Simon's resume.

The resume is quite luxurious.

It can be said that except for a Fields Medal and the Wolf Medal, Simon has won all the awards in the field of algebraic geometry.

Next, I would like to invite Professor Simon of the University of Bonn, Germany, to bring the report of today's meeting. ”

Papapapa~!

There was a round of applause.

Simon walked over to the chairman's table with the microphone in hand.

Next, open the slides and project the title of the presentation onto the screen.

《Hitchin type moduli stacks in automorphic representation theory》。

This is the title of the Simon Conference report.

Translated, it is "Hitchin Modular Stack in Autoisomorphic Representation Theory".

Simon coughed lightly, and under the gaze of more than two hundred mathematicians, the forty-five minute report began.

Gu Lu also raised his head and listened carefully to Simon's report.

Simon is known as one of the five genius mathematicians in the field of algebraic geometry, and for good reason.

In the front-end time, although Simon suffered losses under Gu Lu, it did not mean that Simon was weaker than Gu Lu.

If Simon gives it his all, it is unknown who will win and who will lose.

Gu Lu opened his notebook and recorded the contents of Simon's meeting report.

“…… To put it simply, in the study of self-defending representations on the domain of functions, the Hitchin stack and its deformations will occur quite naturally. Their geometric properties are helpful for the comparison of trace formulas. ”

Then, in his report, Simon reviews the application of this observation to the following questions.

For example, relative basic lemma, arithmetic basic lemma, higher Gross-Zagier formula......

The Hitchin mold stack has always been one of the hot research directions in the field of algebraic geometry.

And Simon's report can be regarded as the most cutting-edge research results in the direction of Hitchin model stack.

It is obvious that many mathematicians who are currently working on the Hitchin stack have their eyes lit up, listening to Simon's report and writing down something on paper.

Simon finished the report in about thirty minutes.

There were fifteen minutes left in the question-and-answer session, and the people below were very enthusiastic.

Simon easily answered the difficult questions raised by many mathematicians, winning bursts of applause from the audience.

…………

Lunch, Gu Lu and Simon were eaten from the hotel.

"The morning's report was good. While eating lunch, Gu Lu said with a smile while sandwiching a piece of spicy chicken from the dinner plate.

Simon, who had just tasted a piece of spicy chicken, was hissing and spitting cold air.

"Thanks for the compliment!"

Simon said as he sipped mineral water.

"You're not used to eating spicy food?" Gu Lu suddenly asked with a smile.

"Not used to it. Simon pointed to his red lips.

"Then the next time you come to Huaguo, I will take you to Sichuan and Shu when I have time. Gu Lu smiled at the corner of his mouth.

…………

Afternoon.

Gu Lu's forty-five-minute report was scheduled to start at five o'clock.

Sitting in the conference room, Gu Lu crossed his arms, and the old god was looking at the mathematicians who came to the stage to give a ten-minute report.

As mentioned before, in the one-hour report and the forty-five minute report, there is also a ten-minute report.

This 10-minute presentation is reserved for mathematicians who have not been invited to give presentations by the International Mathematical Union.

As long as you apply to the organizing committee of the International Congress of Mathematicians in advance, basically every mathematician will be given 10 minutes to report on the stage in the breakout session.

It is also one of several ways that many unknown mathematicians become famous overnight.

But......

From the morning to now, Gu Lu has listened to at least a dozen ten-minute meeting reports.

But to tell the truth, there is not a single one that can give Gu Lu a bright feeling!

The more Gu Lu listened, the more bored he felt.

I even had the idea of going to other branch venues for a walk.

And at this moment, a Chinese mathematician took the stage.

The Chinese mathematician looked young, about thirty years old, with a square, masculine face and a simple dark suit on his body.

After taking the stage, the Chinese mathematician first glanced in the direction where Gu Lu was without a trace, and then took a deep breath, looking at the more than 200 people below with a somewhat nervous expression.

"Good afternoon, my name is Xu Chenyang, I am from Tsinghua University, China, and the topic of my speech is "The Interaction between Singularity Model and Minimal Model Program". ”

"Interaction between singularity theory and the minimal model program" is the theme of Xu Chenyang's projection to the screen.

After seeing this topic, Gu Lu leaned forward, and his gaze became interesting.

Last year, because Gu Lu solved the two major problems of the minimalist program in one go, the minimalist program, an unpopular direction in the field of algebraic geometry, became a popular research direction in just a few days.

In the past year, papers on the research results of the minimameter program have been published in major journals, and the specific research content is different.

The interaction between the minimalist program and the singularity model has always been a difficult point in the direction of the minima.

After such a long time, there is still not much breakthrough.

Therefore, when he saw that the theme of Xu Chenyang's report was the interrelationship between the singularity model and the minimalist program, Gu Lu was immediately interested.

It's not just Gu Lu.

The rest of the mathematicians in the conference room were also interested, and looked up at Xu Chenyang, who was a little nervous on the stage.

Xu Chenyang took a deep breath and began to report.

In the report, Xu Chenyang first reviewed the latest research on singularity theory, and then discussed their relationship with the minimalist program, including the structure and properties of dual complexes, the proof of the logarithmic canonical threshold rising chain conjecture, and the research results of the "local stability theory" of the KLT singularity.

Since there was only 10 minutes of time for the report, Xu Chenyang only talked about the results of many contents, but did not elaborate on the specific research process.

But what Xu Chenyang said alone was enough to make Gu Lu's eyes shine.

After Xu Chenyang's report ended, Gu Lu was the first to take the lead in applauding.

Then, the meeting burst into applause.
