From Almighty Scholar to Chief Scientist

Chapter 101 How Did He See It? !
After a while, a few more people came in from outside the door.

They are academician Yuan Ya, chairman of Huaguo Mathematics Society, Gong Zhou, secretary-general, and Chen Fei, deputy secretary-general.

The three of them were officially invited to participate on behalf of the Huaguo mathematics community, while Lin Xiao and the others went there in their personal capacity.

Academician Yuan Ya walked in and looked around, and after making sure that everyone had arrived, he said, "Everyone has arrived, so there is no need to say anything else. We have 27 people from the mainland this time, and we will try to live together as much as possible." In a hotel, the conference provided a discounted price, which was cheaper. Of course, except for the six professors who received invitations to report, oh, there is also a classmate Lin Xiao.”

Speaking of this, Academician Yuan looked at Lin Xiao and smiled at him.

After Lin Xiao came back from Romania, Academician Yuan also met and had a meal with these six math geniuses who returned victoriously. Among them, Lin Xiao was naturally the one he paid the most attention to.

In any case, after Lin Xiao published an article in the "Annual Journal of Mathematics" and received a report invitation from the International Congress of Mathematicians, the only difference between them and them was age and qualifications.

Then Academician Yuan turned around and continued: "ICM provides all the charges for the speakers, so I won't say more. Then, our planned departure time is set at [-] o'clock this afternoon, everyone. If you have any questions, just ask them now."

Naturally, there was no problem, and then they discussed other problems. When they were basically gone, they went back to make preparations. After taking their suitcases, they took the bus to the airport together.

It takes 30 hours to travel from Beijing to Rio de Janeiro. After all, one is in Asia and the other is in South America, separated by the Pacific Ocean.

Therefore, these thirty hours were quite tormented.

Thirty hours later, I arrived in Rio de Janeiro. At this time, Brazil time was 7 am on July 29.

After getting off the plane, there was a receptionist at the airport who led them to the bus and went directly to the hotel.

After a long journey, everyone felt extremely tired, so they rested for a day. Anyway, the conference started on August 8, and there were still two days left.

……

The time came to the next day, July 7.

As an invited speaker in the field of number theory, Lin Xiao received a notice from the organizer of the conference that he would come to hold a meeting of speakers in the field of number theory, so he came directly.

The conference will be held at the Rio Centro Convention and Exhibition Center, which will also be the venue for the Congress of Mathematicians.

The Mathematicians Conference is naturally a place where mathematicians gather. Although it hasn't started yet, it is already lively here. There are various reporters and media outside taking pictures. Besides, there are a bunch of people gathered outside.

Some of them wanted to enter the exhibition hall, but they needed to show the staff their participation or work badges. Lin Xiao and the others had already got them from the staff when they arrived, and he was wearing them around his neck at this time.

Looking at those people, Lin Xiao wondered what they were here for.

So he moved closer and listened.

"I proved Goldbach's conjecture! Let me in!"

"I proved the twin prime number conjecture, do you know what you are doing? You are stopping a mathematician!"

……

Hearing these voices, Lin Xiao was startled.

Where did all this come from... Boss?

Or to be more precise, it should be Minke?

Is there a proof of brother's guess, and a proof of twin primes?

I am afraid that the lectures at this International Congress of Mathematicians are not so outrageous.

Probably only folks have this kind of... rich imagination, right?

When Lin Xiao was speechless, he couldn't help admiring the spirit of these people.

It was so persistent that I went straight to the International Congress of Mathematicians.

He looked around again, and there were some heavyweights nearby.

They even pulled posters or blackboards directly to show their achievements on the street.

For these people, the staff turned a blind eye, probably because there were too many people and they were too lazy to take care of them.

Lin Xiao couldn't help being interested. He wanted to see how these folks dealt with the problem. He glanced at it and found that a person not far away showed the Mersenne prime number judgment formula.

The problem he solved was the Mersenne prime number. At this time, I was curious about how this person did it. Moreover, the person who can study the Mersenne prime number judgment formula should not be very 'civilian', right?

He thought about it, anyway, there is still half an hour before the meeting starts, why not take a stroll.

So he walked over and stood in front of the blackboard to read it.

There is a Brazilian squatting next to the blackboard, who is the owner of the blackboard.

When he saw Lin Xiao coming, and the sign on his neck, which indicated that he was here to attend the meeting, he immediately showed an enthusiastic expression on his face.

Those who participated in the meeting knew mathematics, so he stood up directly and said, "Hi, you also know Mersenne prime numbers? Look at my judgment formula. I can be sure that it is definitely better than the Lucas-Lehmer test. better!"

The Lucas-Lehmer test is the current method used to retrieve Mersenne primes and has been around for decades.

As a result, this person directly said that it was better than this method?

Lin Xiao was noncommittal, and simply looked at it, but there was only a short line on the blackboard.

"Let m be an integer, set prime number a, c greater than zero, c greater than a, if (2^a-2)/(2^c-1)=m, then 2^c-1 is a Mersenne prime."

Lin Xiao: "...So this should be a conjecture, right? You didn't prove it."

"If you want to talk about conjecture, then it should be. If it is based on my name, it should be called Ronald's conjecture!"

Hearing Lin Xiao's words, he was very excited, as if he had found a way to make himself famous through the ages.

But soon he said again: "Of course, although it is a conjecture, we can assume that it is true now, and then through this method, we can also accurately find Mersenne prime numbers."

As he spoke, he found a blackboard pen and started writing on the blackboard.

"Look, now we can make a equal to 7, c equal to 19, 7 and 19 are both prime numbers, and then substitute them into the formula, the numerator can be divisible by the denominator, so when the exponent is 19, M19 is a Mersenne prime number."

"Let's give another example. For example, a is equal to 3 and c is equal to 13. They are still valid, and M13 is also a Mersenne prime number."

"For another example, a=5 and c=31, a=13 and c=61..."

"We can find that it's all achievable!"

This Brazilian, probably named Ronald, listed seven sets of numbers, all of which came true.

At this moment, some people around were also attracted by the discussion here, and many people also came here. They were a little surprised when they saw Ronald's display.

It seems... something?

Can it really work?

But at this moment, after observing the formula, Lin Xiao suddenly said, "Try a equal to 29, and c equal to 67."

Hearing Lin Xiao's words, Ronald was taken aback, then found a calculator from the side, and tried it.

As a result, everyone was silent.

When entering the two values ​​mentioned by Lin Xiao, the original formula can be divided evenly, but it cannot get a Mersenne prime number!
People around couldn't help looking at Lin Xiao in shock, how did he see it?
