Chapter 399 (1/2)

At the end of the academic report of chapter 402, Professor bill on the stage took over several pieces of paper with questions from the front row and answered them one by one.

Cheng Nuo stood in the corner. Although he understood some questions, he still listened very carefully.

”It's not my turn yet.” After listening to him for a while, Cheng Nuo murmured in a low voice.

A mathematician sitting in the last row, very close to Cheng Nuo, seemed to hear Cheng Nuo's soliloquy. He shook his head and laughed, and waved to Cheng Nuo, ”waiter, come here for a minute.”

The first sound, although Cheng Nuo heard someone call the waiter, but he has not yet put into the role, did not react to it is himself.

”Waiter, come here for a minute!”

Until the mathematician called for the second time, Cheng Nuo was stunned for a second time. With a waiter like smile on his face, he went to the mathematician and said, ”Sir, do you call me?”

You look at the hotel and ask, ”is this a mathematician?”

”Yes, sir. I've just been working in the hotel for a few days, so if there's anything inappropriate, please forgive me.” Cheng Nuo estimated that the mathematician should have seen himself sitting in his seat listening to lectures, so he said so.

”I think you were listening carefully to Mr. Bill's academic report just now?” The mathematician asked with a smile, ”how much do you understand?”

Cheng Nuo waved his hand. ”Sir, I'm just admiring a Fei prize winner like Mr. bill. After listening to this, I can't understand how much.”

”Only understand more than 90 percent.” Cheng Nuo added in his heart.

Mathematician a pair of true such expression, smile way, ”although do not understand, but feel this kind of atmosphere is also very good.”

Obviously, he interpreted Cheng Nuo's ”not understood much” and his subconscious understanding was ”not understood at all”.

He waved to Cheng Nuo, ”please get me a drink.”

Although he was reluctant, because he didn't know when Professor bill would answer his question, he still nodded with a smile to avoid exposure. ”OK, sir, wait a moment, now.”

After saying this, Cheng nuomi hurried out of the back door of the auditorium.

…………

In the auditorium, Professor bill, who was standing on the stage, had just finished answering the last question and simply took a drink of water, then he picked up the next note.

Professor bill glanced and said with a smile, ”that's a little interesting.”

Then he picked up the microphone and explained to the audience, ”I found an interesting question. You can listen to it.”

”The problem is: in the case that the analytic map of Lie group fluctuates irregularly at the zero point, the k-value function of affine DL family?”

”If I can ask this question, I understand almost everything I have just said. Why do I say this topic is interesting? In fact, those who have noticed it will find that I have already mentioned this problem just now. ”

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

Cheng Nuo also came in from the back door with a drink. Seeing that he had already talked about his problem, he immediately stopped to listen.

Professor Bill went on to say, ”it is well known that lie groups are real or complex manifolds with group structure, and the addition and inverse operations in groups are analytic mappings in the manifold. If we let K be an algebraically closed field and a ^ n be an n-dimensional affine space on K

”From this we can easily conclude that f ∈ K [x1, X2, X3 Xn], Z (s) = {x ∈ a ^ n | f (x) = 0 for all f ∈ s}. ”

If there is s such that V ∈ a ^ n satisfies v = Z (s), a nonempty algebraic set V is considered irreducible, such that I (V) is the ideal of all functions with zero value on V, I (V) = {f ∈ K [x1, X2, X3 Xn] | f (x) = 0 for any affine algebra set V, its coordinate ring is the quotient of polynomial to the above ideal
