Chapter 160

Academic lectures are ongoing.

The topic is about affine DL clusters.

Although the original origin of affine DL clusters is derived from arithmetic geometry, many of the related problems are problems of Lie algebra.

Therefore, Academician Di's lecture is to introduce the latest research results on affine DL clusters from the level of Lie algebra.

Similarly, it includes connections and applications to arithmetic geometry.

There is a lot of content involved, algebra, geometry, functions, and the content is complicated.

And considering the factor of time, Academician Di spoke very quickly, almost at the speed of two or three minutes of a page of PPT.

Auditorium.

Gu Lu raised his head and listened carefully to Academician Di's lecture, while raising his pen to quickly record lines of formulas in his notebook.

Gu Lu was excited now.

This lecture is simply worth it!

Regarding the research of affine DL clusters, Academician Di is undoubtedly at the forefront of the world.

And the content expounded by Academician Di in this lecture is also full of dry goods.

Almost the core results of the research on affine DL clusters in the past year and a half were shown to the audience one by one.

Let all the audience present have a hearty feeling.

At the same time, I was amazed by the academic research achievements of Academician Di.

It is not an exaggeration to say that the content expounded by Academician Di in this academic lecture is simply the study of affine DL clusters.

With such a significant research achievement, it is fully capable of impacting next year's Fields Medal.

Unfortunately, Academician Di is over 40 years old for the Fields Medal and cannot be included in the list of candidates.

This made everyone present, including Gu Lu, a little regretful.

This is also the current situation of the Chinese mathematics community.

The golden generation of mathematicians has not yet fully grown up.

On the world stage, it is still the older generation of mathematicians like Academician Di who are barely supporting the cards of the Chinese mathematical community.

Although it is not to be said that there is no shortage of mathematicians, it is a fact that no one among the young and middle-aged mathematicians in China can carry the banner of the Chinese mathematical community.

............

The lecture continues.

According to the pre-arrangement, the whole lecture will last for three hours.

Two hours of explanation time, one hour of Q&A time.

When Academician Di lectured on Lange's theorem and finite reduction groups, it was clear what Academician Di needed to explain in this lecture, and it was almost at the end.

Sure enough, five minutes later, Academician Di ended his speech, and then looked at the audience with a kind smile.

"That's all I want to say, let's move on to the Q&A. Later, someone will give you a small note, and you can just write the question on it, one question for each person. I'll pick a few targeted questions to answer. ”

Academician Di did this in order to avoid someone asking some innocuous questions and wasting everyone's time.

Gu Lu's side, waiting for someone to hand out pieces of paper, Gu Lu glanced at the content recorded in the notebook, and then thought about what questions to ask.

Suddenly, Gu Lu realized that he had overlooked something, and turned his head to look at the seat next to him.

Su Xi sat next to Gu Lu, completely entering an unconscious state at the moment, his little head was little by little, looking like he wanted to sleep but didn't dare to sleep.

For her, listening to such a highly professional mathematics lecture is indeed difficult for her.

Gu Lu smiled bitterly and shook Su Xi's arm.

Su Xi woke up instantly, and when he realized what had just happened, Su Xi's face was slightly red, "I'm sorry, I just couldn't hold back, so I fell asleep." ”

At the beginning of the first ten minutes of the lecture, Su Xi still cheered up and listened carefully.

However, Su Xi knew every word that Academician Di spoke, but when they were connected together, it was like a book from heaven to her as a liberal arts student.

What affine DL cluster, Lange's theorem, feature subset, Frobenius morphism, Su Xi didn't understand what it was at all.

But Su Xi still barely listened.

But then...... I couldn't resist the sleepiness of opening the shop, so I fell asleep.

"The lecture is over?" Su Xi asked in a happy tone when he saw that Academician Di on the stage did not speak again.

Gu Lu shook his head and replied, "Not yet, I guess there will be an hour before it ends." ”

Gu Lu saw Su Xi's sleepy face, so he said, "Why don't you go back first, and I'll just take a taxi back after the lecture is over." ”

Su Xi stubbornly shook his head, "No, I'll accompany you!"

The note was quickly sent to Gu Lu, who picked up the pen and wrote the questions he wanted to ask on it, and then folded it and handed it to the staff.

The staff handed over the collected notes to Academician Di.

While picking out the questions, Academician Di explained to everyone, "Due to time reasons, I can only pick a few important questions to answer. As for those questions that were not picked, you can talk to me privately if you have the opportunity. ”

"Let's take a look at the first question, which asks about affine DL clusters, can they be studied by pure arithmetic geometry?"

My reasons are twofold: first, affine DL clusters are derived from arithmetic geometry, but they are only ......."

The pace of Academician Di's answers to questions is still very fast.

However, there are too many questions, and some of them require a period of time to calculate, so after half an hour, only five or six questions were answered.

"Alas, I wonder if Elder Di will answer my question?"

Didn't Di Lao say it, just answer some high-quality questions, and skip those questions that are only symbolic, or the level of difficulty is not high. ”

"However, I don't fully understand what Elder Di explained earlier, and I can't ask a high-level question!"

"Me too, there are a lot of things that I don't fully understand. So I asked a perfunctory question, and it is estimated that most of Academician Di will not answer me. ”

Several mathematicians sitting in the front row of Gu Lu were discussing in a low voice.

Su Xi, who was swiping his mobile phone next to him, also heard the conversation of the people in front of him, so he turned his head to look at Gu Lu beside him.

"Among the questions that Academician Di answered just now, are there any questions you asked?" asked Su Xi.

Gu Lu shook his head and smiled bitterly, "No." ”

"Then do you want me to ask Academician Di out in private, and you ask him questions in person?" asked Su Xi with a blinking of his sparkling eyes.

"Uh...... That's not necessary. Gu Lu waved his hand and refused, "Don't bother Academician Di so much, I'll just ask others when I go back." ”

As far as he knew, there was an old professor who studied affine DL clusters in the Yan University School of Mathematics, and if Academician Di didn't answer his question, he could go back and ask the old professor.

Just as Gu Lu and Su Xi bowed their heads to talk, Academician Di on the stage swept his eyes to a piece of paper, and then sighed softly.

"Hey, that's an interesting question. ”
