The super scholar system becomes a scholar in one second

Chapter 348 Sieving Method
If it is proven, then everything is easy to say, but if it cannot be proved, then Qin Luo's reputation will be completely shattered, and he will even bear the infamy of being too ambitious.

So ambitious?Suicide?
Hearing Father Ye's words, Ye Liang nodded approvingly.

This guy Qin Luo is committing suicide.

Qin Luo didn't hear the sneer of the Ye family's father and son, but even if he heard it, Qin Luo would only smile.

As a top student with a system, he really couldn't take the Ye family father and son seriously.

Even after Ye Liang made a wonderful report on topological functions, the same is true.

Qin Luo wrote very slowly, every word, every word was written carefully, but as time went by, there were more and more calculations on the whiteboard.
"1. If D cannot be adjacent to ABC at the same time, the color number will not increase. If D cannot be adjacent to C, then DC will use one color..."

"2. If D is adjacent to ABC at the same time, on the plane, then D must be in the center or periphery of the adjacent graph of ABC..."

"3.……"

5 minute, 10 minutes, half an hour...

Time passed by every minute and every second, and the noisy discussions gradually disappeared, the hearty voices gradually disappeared, and in the end even the breathing stopped, and the entire lecture hall fell into a deadly silence.

"Have you brought a pen and paper?" When Qin Luo's formula occupied more than half of the whiteboard, Wang Xuecai turned to look at the teaching assistant behind him.

The teaching assistant is a graduate student, about 24 to [-] years old. When he heard Wang Xuecai's words, he immediately took out a pen and paper from his briefcase and handed it to Wang Xuecai.

"Give me a copy too." Song Baoguo said suddenly.

"And me." In the next second, Zhou Haizhong was not to be outdone.

The corner of the assistant's mouth twitched, and he silently emptied his briefcase.

"Thank you."

Wang Xuecai nodded with a smile, took the pen and paper and put it on his knee, his eyes gradually became serious.

But after a while, his brows gradually wrinkled.

As one of the leading figures in the Chinese mathematics field, he can be regarded as one of the people who have gone the furthest in the Chinese mathematics field. He sees problems more clearly than others.

The method Qin Luo uses is slightly different from the conventional method, he uses the sieve method!

Sift out all the impossible, and the rest is the answer!
However, countless examples have proved that the four-color conjecture may not be suitable for the sieve method argument.

What is he trying to do?The wrinkles between Wang Xuecai's brows became deeper and deeper. He unscrewed the cap of his pen and began to check the calculations in his notebook.

The Ye family father and son sitting in the corner on the other side did not have the slightest worry on their faces, but had a smile on their faces.

Like Wang Xuecai, they are also outstanding in the field of mathematics. Among them, Ye Liang is a professor of mathematics at Johns Hopkins University, which is enough to show his extraordinary ability.

Therefore, Wang Xue was able to understand Qin Luo's argument, and he could understand it too.

Watching Qin Luo's argument process that filled the whiteboard, the corners of Ye Liang's mouth curled up.

"Sieve method!"

What does he want to do?
Not only he was thinking about this question, Ye Kang was also thinking about it.

The sieve method is a common argumentation technique in the process of mathematical argumentation.

But this method of mathematical demonstration is only applicable to some specific conjectures.

However, the four-color conjecture is not included.

The reason is also very simple, there are too many possibilities for four-color conjectures, and they cannot be screened out at all.
