Chapter 161

Academician Di's light voice naturally attracted the attention of many people in the lecture hall.

After all, from the beginning of the lecture to the present, Academician Di has been indifferent.

That slightly surprised look appeared on Academician Di's face for the first time.

"Interesting, that's kind of interesting. Academician Di glanced at everyone and said with a smile.

Then, Academician Di helped the microphone and explained to everyone in the audience, "I found an interesting question, you can listen to it." ”

"The question is: in the case of the Lie group analytic mapping that fluctuates irregularly at the zero point, does the affine function of the DL cluster?"

"To be able to ask this question shows that I have almost understood what I have just said. The reason why I say this question is interesting, in fact, those who notice it will find that I have mentioned this question in one stroke when I just talked about it. ”

"We have been doing this research, but so far there is no conclusive conclusion, so I can only give you an answer that I understand. ”

Offstage, Gu Lu raised his head abruptly the moment Academician Di finished reading the question, and his eyes stared at Academician Di.

"What's wrong?" asked Su Xi curiously.

Gu Lu swallowed his saliva and said slowly, "What Academician Di is talking about now is the question I just wrote on the note. ”

After saying this, Gu Lu pricked up his ears and concentrated his attention, trying not to miss every word and word that Academician Di said!

On the stage, Academician Di continued, "As we all know, Li groups are real manifolds or complex manifolds with group structures, and the addition and inverse operations in groups are analytic mappings in the group. If we let a k be an algebraic closed field, and let A^n be the n-dimensional affine space over k. ”

From this, it can be easily concluded that f∈k[X1,X2,X3...... Xn], Z(S)={x∈A^n|f(x)=0 for all f∈S}. ”

"If S exists such that V∈A^n satisfies V=Z(S), a non-null algebraic set V is considered irreducible, so that I(V) is the ideal of all functions with zero values on V, I(V)={f∈k[x1,x2,x3,...... xn]|f(x)=0 for an arbitrary affine algebraic set V, whose coordinate ring is the quotient of the polynomial pair above ideal. ”

"So, here's the problem......"

On this issue, Academician Di seems to be very enthusiastic. The first few questions answered were all seven or eight minutes old, and this question has been explained for nearly twenty minutes before it has the momentum to stop.

"That's all I understand about this. It's just some very conceptual stuff, after all, I've been working on affine DL clusters for almost two years, but I still haven't made a landmark breakthrough on this issue. Perhaps, in the future, one of you may be able to solve it. ”

After speaking, Academician Di sighed, and then his eyes fell on Professor Myers in the second row, "Professor Myers, what is your point of view?"

In the entire newspaper hall, except for Academician Di, this Professor Myers is undoubtedly the person with the highest attainment in the field of DL clusters.

After pondering for a few seconds, Professor Myers shook his head and said in English, "In the case of the irregular fluctuation of the Li group analytic mapping at the zero point, the study of affine DL clusters is much more difficult than the case of zero point determination, especially the study of its K value function, I can't imagine how difficult this coefficient is." ”

"I can say very responsibly that no one will solve this problem in the next five years! ”

Gu Lu, who got the answer from the two bigwigs, leaned back in the chair all of a sudden, and a feeling of loss and boredom came to his heart.

It feels like sitting on the edge of the bed and smoking a cigarette after just finishing a naked hand-to-hand fight.

Gu Lu's question was certainly answered by the two bigwigs, but the answers of the two bigwigs were very unified.

That's ......

For Gu Lu's question, they can't give a standard answer!

That is...... Can't answer!

Gu Lu is very uncomfortable!

According to Professor Myers, most of his doubts will not be answered in the next five years.

Unless......

In front of the lecture table in the lecture hall, Academician Di held up the note and looked at the audience with an inquiring gaze, "Finally, I would like to take the liberty of asking, I don't know which one here raised this question, can you let me know about it?"

One second, two seconds, three seconds......

The atmosphere fell into an eerie silence, and more than ten seconds passed, and no one in the audience raised their hands.

Su Xi stabbed Gu Lu who looked up at the sky in a daze and was slightly distracted.

"What's wrong?" Gu Lu came back to his senses.

Su Xi pointed to the platform, "Academician Di is calling you." ”

"Call me?" Gu Lu was stunned for a moment, but still stood up at Su Xi's signal.

Academician Di thought that the mathematician who wrote this note did not want to show up, but when he was about to give up, he saw a tall and handsome figure suddenly standing in the back row.

A look of surprise flashed on Academician Di's face, he lifted the piece and looked Gu Lu up and down, "Young man, this piece of paper is yours?"

"If no one else asks the same question, I think this piece of paper would be mine. Gu Lu directly and generously admitted.

"The future is terrifying, the future is terrifying!" Academician Di sighed, "Which school are you, I don't seem to have seen you in the Chinese Academy of Sciences before?"

Gu Lu replied, "I just entered Yan University this year as a lecturer. ”

"At this age, you're already a lecturer, not bad, not bad!" Academician Di said two good in a row, "Then who is your teacher?"

"Ji Changyi. ”

"Academician Ji?" Academician Di seemed to think of something, "You should be the closed disciple of Academician Ji, if I remember correctly, your name should be ...... Gu Lu!"

"Exactly the students. ”

"I'm still weird. How could a person who seemed to be still in graduate school ask such a profound question, but Gu Lu's words, it would make sense. I just met with Academician Ji some time ago, and he mentioned you, and he praised you very much! He said that in less than ten years, you will definitely stand at the top of the world's mathematical pyramid!"

Gu Lu waved his hand and smiled modestly, "The teacher really thinks too highly of me." ”

Academician Di smiled, and then said softly, "Did you hear the answers I and Professor Miles gave to your question just now?" ”

Gu Lu nodded, "I heard it." ”

"Do you have any ideas for the question you raised, that is, the k-value function of affine DL clusters in the case of Lie group analytic mapping fluctuating at zero point?"

"There are some. ”

"Oh?" Academician Di's interest was raised at once, "Then you can talk about it." ”

Gu Lu pondered for a few seconds, and then slowly spoke, "Regarding the construction of a function that expresses the K value of affine DL clusters, I think it ......."
