Chapter 211: Simplifying the calculation process

Classroom 210.

Xu Qingzhou followed the instructions of the girl with the bun hairstyle, moved the extra tables to the side, and carried a broom to help clean up.

"Why are you cleaning now?"

"This place was originally for stacking miscellaneous items." The girl pointed to the tables stacked on the side and said helplessly: "However, it seems there are many more people coming this time than expected."

Xu Qingzhou nodded, and then heard Ren Chujun sigh and say: "The arrangements for these people are really amateurish. The posters and guide signs are unclear, and the equipment was all checked temporarily and is full of loopholes. It's too worrying."

"What are your thoughts?" Xu Qingzhou smiled.

"Of course, it's to push through all the processes in advance, assign work responsibilities to individuals... Of course, the most important thing is to consider all the variables that might be encountered."

But Xu Qingzhou used full English, and those technical terms soon made her dizzy, so she simply acted as a heartless tool person.

"Senior sister, from today on, you are my idol!"

The old gentleman shook his head and continued to lower his head, doing calculations.

Stavine had already opened the paper on the proof of twin primes and asked impatiently.

"According to the numerical research done by Rosser and Schoenfeld in 1962, it is known that when x≥114514..."

Another boy also said.

Hearing the girl talk eloquently, Xu Qingzhou couldn't help but point out: "So, why are you working here alone?"

Xu Qingzhou shook his head and drank water to moisten his throat: "To be precise, I'm not from your school."

!.

*Thump~ thump~* A thin, tall middle-aged man walked in with two students, looking around the classroom, somewhat surprised: "Little Ren, you've already finished cleaning? The speed is enough..."

Xu Qingzhou signaled, and she took an eraser to wipe the blackboard clean.

Two minutes later, Stavine was thoughtful, and finally, his eyes brightened, evaluating: "Hmm, this step is done perfectly."

The old gentleman's pen tip tapped a few times: "Student Xu Qingzhou, in the 48th formula, mp~2c_2\frac{x}{(\lnx)^2, can it be scaled down to mp(z)(m, p′...?"

Ren Chujun handed Xu Qingzhou a bottle of mineral water and asked: "Junior brother, you look familiar. Which department are you from?"

This old gentleman was named Wang Yiyuan, an academician of the Academy of Sciences. He was the first in Xia Nation to apply the sieve method in analytic number theory to the study of the Goldbach conjecture, proving 2+3. This was the first time Xia Nation scholars had jumped to the world's leading position in this research field.

Xu Qingzhou explained it to the other person bit by bit.

Xu Qingzhou glanced at the paper, pondered for a few seconds, stood up: "Directly calculating the value of the prime-counting function is very inefficient, so I used the Prime Number Theorem."

The middle-aged man's voice stopped abruptly, looking at Xu Qingzhou: "Xu Qingzhou?"

Ren Chujun pulled up a stool and watched from the side, originally wanting to listen more and gain some knowledge.

Ren Chujun was choked and coughed for a long while, staring at Xu Qingzhou with wide eyes, stunned: "You... you are not from our school?"

While he was speaking, he wrote a row of formulas on the blackboard.

Xu Qingzhou unscrewed the bottle cap and said: "I'm not from the Student Union."

Xu Qingzhou looked at her without speaking.

He completely proved the twin prime conjecture, but whether it was mathematics or physics, there were changes with each passing day every year.

Ren Chujun didn't have time to dwell on it and started working.

A boy had an admiring expression: "Senior sister, you actually dragged the big god here to clean!"

Xu Qingzhou turned his head to look at Ren Chujun and raised the mineral water: "Then I'll go get busy first. This bottle of water will serve as my reward."

"Actually, I know there are still many people who want to hear your brilliant report." Deng Deng Zeer shrugged and said: "It's a pity, the visas for your Xia Nation are too difficult to handle."

Ren Chujun cheered herself up and said: "The teacher sent me here to be a staff member, helping you with odd jobs and such."

In Xia Nation, and even in the world, he could be considered a leading figure.

Dragging a guest to do work—although the teacher didn't criticize, it was estimated that he would be laughed at for a long time. Although Andrew Wiles's proof of Fermat's Last Theorem was hailed as a masterpiece in the history of mathematics, his original proof process was complex and lengthy, involving profound mathematical theories, such as elliptic curves, modular forms, and Galois representation theory, etc.

This person was exactly the teacher who had just taken Deng Deng Zeer to pick up friends.

After speaking, he took the document bag next to him and left.

From the work permit, it could be seen that this girl was named Ren Chujun, the deputy minister of the Publicity Department of the Student Union. However, she always had a heart to usurp the throne and become the chairperson.

"Oh, so it was... Hmm? *Cough cough~*"

"Oh, so it's the Mathematics Society?" Ren Chujun drank some water.

"Xu, let me introduce you. This is my colleague Stavine Jell, and this beautiful lady is Grace Aiheti, from Princeton."

Ren Chujun was tearful; at this moment, she felt her dream of being chairperson seemed to be shattered.

Just like when Zhang Yitang proved that the prime gap was less than 70 million, establishing a framework, mathematicians continuously improved his method based on this framework, successfully reducing 70 million to 246.

"Regarding the adjacent iterative expression of the prime difference interval here, how did you get pn+1-pn=（pn/n）^2=（nlnpn/n）...?"

Xu Qingzhou immediately cheered up and listened carefully to the other person's exposition.

"."

"Well, actually, it's because the people in our department have all been arranged to go out by the teacher."

Grace said: "Yes, compared to these people, we are lucky." Xu Qingzhou smiled and invited everyone to sit down. At this time, Ren Chujun next door walked in with a bitter face.

"Hmm, please speak."

"Arrived." The middle-aged man replied, his brain not having turned around yet.

30 minutes passed in a flash. There were 8 more people in the classroom. Sitting on the left was an old gentleman with white hair.

"Hello everyone." Xu Qingzhou said. These three people all looked to be around 30.

Xu Qingzhou also wrote down the formula and verified it, finding that the entire calculation process was indeed much simpler. He thanked him: "Old Wang, thank you for your train of thought."

"."

"Okay."

"Actually, my question is about Cramer's theorem." Grace spoke up.

"Xu, regarding this formula between page 45 and 46 of your paper, can you explain it in detail?"

"Hmm." Xu Qingzhou smiled and nodded, standing up: "Deng Deng Zeer and the others have arrived?"

"Capable people do more work. I am someone who wants to be chairperson in the future, so of course I have to do it myself."

"Why did you come?" Xu Qingzhou asked.

Xu Qingzhou had just simply gone through this place initially; he could calculate the result he wanted, so he didn't bother with it.

"Then please help me wipe this blackboard." Seeing Ren Chujun somewhat reserved, Xu Qingzhou thought about letting her do something so she wouldn't feel uncomfortable.

The two spent 20 minutes cleaning the classroom inside and out and sat on chairs to rest.

Once the conversation started, the girl talked eloquently about a lot of things.

"Here, it is necessary to first prove pn+1-pn=2k..."

On this side, Xu Qingzhou came to 209 next door. Besides Deng Deng Zeer, there were three more foreigners.

Subsequently, mathematicians subtracted the redundancy, rearranged the lemmas and theorems in the proof, and used higher-dimensional algebraic varieties or more complex elliptic curve families to replace the original elliptic curves.

Besides these, those classic theories in the mathematical world were also being improved, such as the original Riemann function r(x), which was a special function defined on the interval 【0, 1】.

Someone proved that the Riemann function is continuous at all irrational points in (0, 1) and discontinuous at all rational points, but there is a limit at every point, and the limit is 0.

There was also calculus. Over a long period of time, mathematicians introduced limit theory to strictly define differentiation and integration, solving the problem of logical imprecision that existed in the early days of calculus.
