Chapter 553

"How do you say he will prove it?" Dreine turned to look at farser, who was beside him.

"It's said that he used the sifting method well..." Farshyan said with a smile.

Although for mathematicians, they can use almost all the mathematical tools, but there are also some very handy ones, such as Qin Luo. In his proved conjectures, almost every one of them has the shadow of sieve method.

According to farshyan's estimation, qinluo is no exception this time.

"It will be." Said Denise with a smile.

Sift method and Goldbach conjecture, almost completely do not match, but for qinluo, he really has a little expectation.

Maybe qinluo really used the sieve method to find out Goldbach's scientific model.

Of course, Qin Luo, who is standing at the top of the report at the moment, doesn't know the ideas of dlinese and farshyan. If he does, he may burst into laughter, because the method he quoted this time is really sieve method, which is different from the previous screening method. This time, he uses the original even number screening method!

In the eyes of all, Qin Luo twisted off his pen cap and wrote on the whiteboard,

R (n) ≤ "7.8 Π{(p-1) / (P-2)}Π{1-1 / {(p-1) ^ 2} {n / (lnn) ^ 2}.

among them, the numerator of the first series is greater than the denominator, and the value is (the fraction greater than one). The limit value of the second series is 0.66... And its 2 times are greater than 1.

N / (lnn) is about the number of prime numbers contained in N number: where (lnn) is the natural logarithm of N, which can be converted to 2 {ln (√ n)}

……

At the beginning, people didn't like it, because Qin Luo's angle of penetration was very general. In the whole mathematical world, countless people started from the same angle, but no one could successfully deduce.

People should think that Qin Luo can only break halberd.

However, it did not take long for the public to stare at the whiteboard in front of them.

At the same time, Wang Xuecai, who sits at the end of the team, also stares at the whiteboard.

Although he is old and his eyes have lost their original sharpness, at this moment, he is trying his best to see clearly and clearly.

"Lao Zhou, come on, bring me your reading glasses..." Wang Xuecai said without looking back.

"Don't even think about it. Here you are. What can I bring?" Zhou Haizhong said.

"Lao Zhou, I said why you are so stingy. If you come back home, I will buy you 100 pairs. No, 1000 pairs. I will let you take them every day and change them into fancy ones. In three years, you can't get the same kind." Wang Xuecai said.

Zhou Haizhong looked at Wang Xuecai deeply, then pushed his glasses with pride on his face and said, "don't even think about it."

“……”

If you can, Wang Xuecai would like to put Zhou Haizhong on the ground!

-

in the front row, a crowd of Princeton bulls gradually turned up their mouths.

They guessed right. What Qin Luo used was still the sieve method he was familiar with!

However, with the passage of time, their smile gradually solidified in the face.

The sieve method used by Qin Luo seems to be a little different from that used by others.

"Val, have you ever seen this sifting?" Said dlinese.

"No, but there seems to be a lot of sifting." Said Jens in a calm voice.
