Chapter 402

At the end of the academic report, Professor Bill on the podium took a few notes with questions written by him handed over 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 seriously.

"It's not my turn to have a problem yet!" After hearing for a while, Cheng Nuo muttered in a low voice when he saw that his problem had not yet been reached.

A mathematician sitting in the last row, very close to Cheng Nuo, seemed to hear Cheng Nuo talking to himself, shook his head and smiled, and waved to Cheng Nuo, "Waiter, come here!"

The first sound was that although Cheng Nuo heard someone calling the waiter, he had not yet taken part in the role and did not react.

"Waiter, come here!"

Until the mathematician called him for a second time, Cheng Nuo was stunned for a moment, and walked to the mathematician with a waiter-like sign smile on his face, "Sir, are you calling me?"

The mathematician nodded, looked at it and asked, "Are you the waiter of this hotel?"

"Yes, sir, I have just entered the hotel for a few days, so if there is anything inappropriate, please forgive me." Cheng Nuo estimated that the mathematician should have seen him sitting in his seat and listened to the lecture, so he said so.

"I see, you were listening to Mr. Bill's academic report carefully?" the mathematician asked with a smile, "How much did you understand?"

Cheng Nuo waved his hand, "Sir, joking, I just admire Philippine Award winners like Mr. Bill. After listening to it, I just joined in the fun, how could I understand how much?"

"I only understood more than 90%." Cheng Nuo added in his heart.

The mathematician looked like this indeed and smiled, "Although I don't understand, it's good to feel this atmosphere."

Obviously, he subconsciously understood Cheng Nuo's words for "not understanding much".

He waved his hand to Cheng Nuo, "Please help me get a drink."

Although I was reluctant, because I didn't know when Professor Bill on the stage would answer his questions, in order to avoid being exposed, I still smiled and nodded, "Okay, sir, wait a moment, right away."

After saying this, Cheng Nuomai walked out of the back door of the auditorium in a hurry.

…………

In the auditorium, Professor Bill, who was standing on the stage, just finished answering the previous question, took a simple sip of water, and picked up the next note.

Professor Bill glanced at him and laughed, "This question is interesting."

Then, he picked up the microphone and explained to everyone in the audience, "I discovered an interesting problem, everyone can listen."

"The problem is: when the Li group analytical map is fluctuating irregularly at zero point, is the k-value function of the affine dl cluster?"

"Being able to raise this question means that I have already understood almost all of the content I just said. Why do I say this question is interesting? In fact, those who notice it will find that this question was mentioned in one sentence when I just talked about it."

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

Cheng Nuo also walked in through the back door with a drink. Seeing that he had already talked about his problems, he stopped and stopped and listened.

Professor Bill continued, "As we all know, Li group is a real manifold or a complex manifold with a group structure, and the addition and inverse operations in the group are analytical maps in the page. If we make a k an algebraic closed domain and a^n is an n-dimensional affine space on k."

"From this, it can be easily concluded that f∈k[x1,x2,x3...xn],z(s)={x∈a^nf(x)=0 for all f∈s}."

"If s exists so that v∈a^n satisfies v=z(s), a non-empty algebraic set v is considered irreducible, so that i(v) is the ideal of all functions that take zero values ​​on v. i(v)={f∈k[x1,x2,x3,...xn]f(x)=0 for any affine algebra set v, and its coordinate ring is the quotient of the polynomial for the above ideal."

"Then, the question is..."

Regarding this question, Professor Bill seemed very enthusiastic. The previous questions answered were all done in one or two minutes, and this question has been explained for more than five minutes before it can stop.

"What I understand about this issue is these things. Of course, what I am talking about may not be correct. If you have different opinions, we can discuss them privately."

"Finally, I want to ask, I wonder if anyone here asked this question, can I get to know me?" Professor Bill held up the note high and looked at the audience with his exploratory eyes.

One second, two seconds, three seconds...

The atmosphere fell into a strange silence. More than ten seconds passed, and no one in the audience raised his hand.

The mathematician sitting in the last row looked at the half-note that Professor Bill held up, and for some reason, he felt a familiar feeling.

Professor Bill's expression was also a little embarrassed, and he smiled embarrassedly, "Since this colleague is unwilling to show up, let's talk in private, and talk in private..."

After saying that, he picked up the next note to answer the question.

In the audience, the hundreds of mathematicians who came to listen to the lecture were also talking.

"What's going on with that person? I gave up on the opportunity to get in touch with Professor Bill so easily. What did you think?!" The mathematician in the last row muttered without deliberately lowering his voice.

Cheng Nuo smiled bitterly. He didn't expect that Professor Bill would attach so much importance to it just by asking a question.

He also wanted to touch the boss in the front row, but reality did not allow it, so he had to give up.

Just treat this as a secret.

"Sir, the drink you want." Cheng Nuo said to the mathematician who was still muttering.

The mathematician took the drink handed over by Cheng Nuo and said dissatisfiedly, "So long."

Cheng Nuo said apologetically, "When I first came in, I heard Professor Bill talking about a very interesting question, so I stopped and listened for a while."

"Interesting?" the mathematician snorted, "For you laymen, it's probably just interesting. The meaning of this question is not that simple."

Cheng Nuo stood aside with his hands down, without saying a word.

The mathematician waved his hand, "Okay. Go down and do your business."

"Sir, I'll go to work first, and you can talk if you have any needs." The mathematician did not say that, but Cheng Nuo was ready to leave.

The one-hour academic report is about to end. I heard everything I want to hear and ask, and I gained a lot. He needed to find a place to digest it and then rush to the lecture.

Just as Cheng Nuo was about to take a step, he heard the mathematician's voice coming from behind him again, "Your shoelaces are open."

Cheng Nuo looked down and said, "Oh, thank you."

Cheng Nuo squatted down and tied his shoelaces, quickly left the auditorium, without noticed that half of the paper fell out of his pocket.

The mathematician saw this scene and was about to remind Cheng Nuo, but he seemed to have thought of something, and his eyes opened wide unconsciously.

If he remembered correctly, the half piece of paper dropped by the waiter was exactly in line with the torn lines that Professor Bill showed them on the stage.

It should be... the same piece of paper.

Then, wouldn't it mean...
Chapter completed!
