Chapter 553 Proof Begins
"What method do you think he will use to prove it?" Deligne turned to look at Farsyan beside him.
"I heard that his algorithm is good..." Farsyan said with a slight smile.
Although for mathematicians, they use almost all mathematical tools, but some of them are useful and handy. For example, Qin Luo, among the conjectures he proved, almost every conjecture has the shadow of an algorithm.
According to Farsyan's estimation, Qin Luo will be no exception this time.
"That's right." Deligne said with a smile.
The sieve method and Goldbach's conjecture almost did not match at all, but for Qin Luo, he really had a little bit of expectation.
Maybe Qin Luo really used the sieve method to find out Goldbach's scientific model.
Of course, Qin Luo, who is standing on the reporting platform at the moment, doesn't know what Deligne and Farsyan are thinking. If he knew, he might laugh out loud, because the method he quoted this time is really the sieving method , but it is different from the previous sieve method, this time he used the original double-number sieve method!
Under the scorching eyes of everyone, Qin Luo unscrewed the cap of the pen, and then began to write on the whiteboard,
r(N)≤《7.8∏{(p-1)/(p-2)}∏{1-1/{(p-1)^2}}{N/(LnN)^2}.
Among them: in the first series, the numerator of the parameter is greater than the denominator, and the value is (a fraction greater than one). The limit value of the second series is 0.66, and its multiple of 2 is also greater than 1.
N/(lnN) is about the number of prime numbers contained in N numbers: among them, (lnN) is the natural logarithm of N, which can be converted to 2{ln(√N)}...
If it is possible, Wang Xuecai really wants to kick Zhou Haizhong to the ground!
-
However, it didn't take long before everyone's eyes widened and they stared straight at the whiteboard in front of them.
"Old Zhou, quickly, bring me your reading glasses..." Wang Xuecai said without turning his head.
At the beginning, everyone didn't care, because Qin Luo's angle of entry was very general. In the entire mathematics world, there were countless people who started from the same angle, but none of them could successfully deduce it.
"Old Zhou, I told you why you are so stingy. At worst, I will buy you a hundred pairs when you return to China, no, a thousand pairs, and let you carry them every day. You can change the patterns and don't carry the same ones for three years." Wang Xuecai said.
"Don't even think about it, I brought it for you, what should I bring?" Zhou Haizhong said.
"..."
……
Although he is old and his eyes are not as sharp as before, but at this moment, he is also exhausting his eyesight, wanting to see more clearly, and more clearly.
At the same time, Wang Xuecai, who was sitting at the end of the line, was also staring at the whiteboard.
Everyone took it for granted that Qin Luo could only lose his halberd.
Zhou Haizhong took a deep look at Wang Xuecai, then pushed his glasses proudly, and said, "Don't even think about it."
In the front row, the corners of the mouths of a group of big bulls from Princeton gradually turned up.
They guessed right, what Qin Luo used was still the sieving method he was familiar with!
However, as time went by, the smiles at the corners of their mouths gradually solidified on their faces.
The sieving method used by Qin Luo seems to be a bit different from the usual sieving method.
"Fare, have you seen this kind of sieving method?" Deligne said.
"No, but it seems to be a shadow of repeated screening." Faljens said in a calm tone.
