Chapter 199: Someone got there first?!

In the laboratory, Xu Qingzhou was studying the organized data.

Just as expected, when the crystal length was 1.5mm, a maximum vacuum compression of (3.6±0.2)dB was obtained at an analysis frequency of 1MHz, which was (7.0±0.2)dB after considering losses, which was the best experimental effect.

He opened the thesis he had written part of earlier, dragged the data chart into the thesis, and continued typing: The theoretical change curves of system threshold (a) and compression (b) with crystal length. The black dashed line and red solid line are the results without and with spatial walk-off, respectively.

no=1.82, x=3.54pm/v, o=0.0468, t=0.1.

At 3:00 PM, when Xu Qingzhou went to the lounge to drink water, he found that Professor Gu Zhizhong had called twice and there was a message asking him to come to Classroom 1205 of the School of Mathematics if he had time.

Xu Qingzhou guessed that they probably encountered some problems during the demonstration process and returned the call.

Sure enough, they were stuck on two difficulties. The school was urging them quite tightly, hoping to announce the results Xu Qingzhou achieved before "Mathematical Invention," but these two points were very difficult to demonstrate and quite time-consuming.

Xu Qingzhou thanked him: "Thank you, Wang Wang Shixiong."

Read! {

This was his first time feeling the disparity in the human world.

Xu Qingzhou sat down beside Song Yao and tapped the head of Er Miao in her arms.

"Find a time and exercise with me." Song Yao glanced at the exhausted boy. This guy seemed even weaker than before; this couldn't go on.

Xu Qingzhou greeted them.

Therefore, Professor Gu intended to let him, the person involved, explain it.

Simply put, it's simply not human!

"Look at Er Miao, the more I look, the more I think Er Miao is good-looking."

"Hello Academician Wang, hello Professor Feng."

"What are you looking at..." Song Yao subconsciously put her legs down and put on her slippers, imagining that this guy was becoming more and more brazen.

"Hehe, you're welcome." Su Kewei was now completely convinced. If these people were called "Academic Masters," then this junior was probably an "Academic God."

"Kloosterman sum is used here, mainly for dealing with prime number distribution, or rather, the correction of the Selberg sieve method. After all, if the essential defect of the sieve method isn't fixed, this part of the content on prime number distribution can't be handled."

Click on the email.

In the entire classroom, perhaps Su Kewei was the most relaxed. Anyway, he couldn't understand it, so he might as well just give up.

Professor Gu and the others also noticed Xu Qingzhou entering and introduced him with a smile: "Little Xu, this is Academician Wang from the Academy of Sciences, and this is Professor Feng from our school. Both of them are experts in number theory."

Xu Qingzhou nodded: "Fine, wait until I'm busy these few days."

Xu Qingzhou clicked on the URL again. This was a news webpage.

"Up to this step, we can estimate the value of m. For example, as long as we can calculate the upper bounds corresponding to t1i, t2i, t3i, we can estimate the size of (11)."

"So that's how it is. Not bad, not bad. The formula transformation here is very brilliant."

Classroom 1205.

Xu Qingzhou took a sip of soup and nodded, saying: "Mm, that's right, using the Perron formula and some common Z(s) properties."

However, he didn't doubt the strength of the three old professors because of this. Mathematics is like this. When he looks at a certain step in a mathematician's proof process, he also feels inexplicable and has to slowly find the logic within it.

The content wasn't much. After greeting, she said she discovered something interesting and let Xu Qingzhou take a look if he had time.

In the classroom, it was very lively. Rows of complex formulas were reproduced under chalk. With Xu Qingzhou's participation, the demonstration speed was much faster, but solving this part of the derivation still took more than 40 minutes, mainly because precise verification was needed to ensure there were no logical or numerical loopholes.

Xu Qingzhou's gaze slid over the white socks without a trace, thinking that the texture must be very good to touch. Several desks were piled with calculation manuscripts, three old men were surrounding a blackboard, and Wang Wang Shixiong Su Kewei was also there.

Looking at Xu Qingzhou explaining to the three big shots, Su Kewei sighed again in his heart. He hadn't been idle these past few days either; he had been deducing when he had time, but unfortunately, he had only completed one-tenth so far, and it was very difficult.

After communicating with the professors until 8:00, Xu Qingzhou finally returned to the laboratory and stayed there until 11:30 before finishing the collection of today's data and slowly going home.

At 6:00, Su Kewei brought in 5 boxed meals.

Xu Qingzhou shrugged and leaned on the sofa to rest. It was another all-nighter, and his brain was running at high intensity, so he was really tired at this point.

Song Yao chuckled twice in her heart, not believing this guy's nonsense. It's just feet, what's there to look at? Thinking this, she moved her toes again, pushing up the cute pattern on her slippers.

He held the water cup on the table, drinking water while checking messages. This was an email from the UK, and the sender was Katherine Mills.

Ding~ At this moment, Xu Qingzhou's phone rang.

Actually, they should have gone to the cafeteria to eat, but Academician Wang and the others were chatting happily and felt that running to the cafeteria was too wasteful, so they simply let Su Kewei bring it back.

Unexpectedly, this became a difficult point.

But the derivation of this conclusion requires the use of Kloosterman and Weil conjectures, etc. This involves algebraic geometry concepts. When he wrote to this point at the time, he disliked the length and deleted it.

Academician Wang greeted him and pulled Xu Qingzhou directly to the blackboard, saying: "Little Xu, you came just in time. Tell us how this formula transitions to this formula."

However, even while eating, they were discussing the steps.

!.

"I don't know who used to call people clown cats every day."

"Junior." Su Kewei greeted, his movements not slow, already holding a paper cup and pouring tea for Xu Qingzhou.

Xu Qingzhou agreed. When Ren Xiaoling returned at 3:30, he packed his things and went to the School of Mathematics.

Xu Qingzhou thought for a moment, picked up a piece of chalk, and wrote: "Improved theorem, when =1/1168, r=n^+, z=n^, (21) satisfies en(logn)^a"

"We used three methods here, but none of them could be pushed through." Professor Feng took a sip of tea to moisten his throat.

"The younger generation is to be feared."

Professor Gu and Professor Feng showed contemplation. The former had already put down his chopsticks and pulled out a draft paper for verification.

Below is a URL.

Tsk tsk, white socks.

If there was enough time, Professor Gu and the others would probably be able to find a suitable method.

Xu Qingzhou looked at the calculations on the blackboard. For this part, in order to obtain the improved Selberg sieve method, Xu Qingzhou first proved: The Bombieri-Vinogradov theorem in formula (9) can indeed be improved into a new theorem when the value of d is certain.

"Little Xu is here."

In about ten minutes, Xu Qingzhou arrived home, pushed the door open, and Song Yao was sitting cross-legged on the sofa watching TV, with Er Miao lying comfortably in her arms, flicking its tail from time to time, which made him feel very envious.

When he saw the title, the water Xu Qingzhou swallowed into his throat almost sprayed out.

【Indian Imperial Institute of Technology Institute of Advanced Mathematics: Twin Prime Conjecture about to be proven!】

What the hell?

Someone got there first?!
