"It's mostly the man who wants to make a fuss." At the thought of this, Denise shook his head and was about to drop the slab.

But the next second, his wrist stopped, and a people appeared in the corner of his eye, Mr: Qin.

He had just seen this name not long ago, and the other side successively proved Zhou's conjecture and twin prime number theory!

"Interesting boy." Denise grinned, braced up and began to slide the slab.

The next second, however, Denise froze.

What did he see?

4 quick shapes of different maps, they are labeled in turn, ABCD.

The following is a reasonable inference made by Qin Luo.

"1. If D cannot be adjacent to ABC at the same time, then the color number does not increase. If D cannot be adjacent to C, DC uses the same color..."

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

”Sifting! "The corner of his mouth rose, and he gave a faint smile.

As a senior professor of mathematics in Princeton, he used the method of mathematics.

However, there are many people who use the sieve method to verify the four color conjecture, but none of them succeed.

Denise laughed and shook his head. "Another stubborn young man. "

" what? "When he heard dline's words, Henrik next to him came up.

"There is a young man in China who wants to prove the four color conjecture with sieve method." Said Denise with a smile.

Sieve method?

Henrik laughed and said, "it's another young man who doesn't know the height of the earth."

"By the way, who is he?"

"Qin Luo."

Qin Luo?

Hearing Qin Luo's name, Henrik was stunned for a moment. He flashed doubts between his eyebrows and murmured, "what a familiar name."

"The young man who proved Zhou's conjecture and twin prime numbers."

"It's him Henrik suddenly realized, and then there was a light in his eyes.

"I'll have to have a good look."

And Henrik's head came up.

At this moment, they widened their eyes and couldn't move their eyes for a long time.

"OMG, how could this be possible?" Henrik could not help but let out a cry.

What's the situation?

Hearing Henrik's voice, farjens, a blonde, inquired.

"What's going on?"

"Farjens, you've come just in time. Look at this paper. Someone uses the sieve method to prove the four color conjecture." Henrik waved to farjens and said aloud.

"Four color conjecture demonstration?" Farjens raised his eyebrows, and a fine light flashed through his eyes.

He would like to see what's special about the paper that can surprise Henrik.

Farjens looked at every word and every word carefully.

For a few minutes, farjens's face grew more and more astonished, and for the first time he saw someone using the sifting method so skillfully.

When D is in the adjacent center of a, B and C, then D is surrounded by a, B and C, and the area of D increases significantly From this point of view, the four color theorem should be understood as "3 + 1" color. This 1 represents the color that can be used again. In other words, when expanding outward, there is one color that can be used again, that is, the "1" color. "

"According to the above inference, the four color theory is established."

"Tap!"

The flat panel falls to the ground, and the screen instantly turns into fragments.
