Chapter 174: Hmm, steady

The two finished their meal and sat down. Xu Qingzhou said helplessly: "It seems that there is really no time to move this month."

Last weekend, he went to clean the new home once. Since then, he hasn't been there, soaking in the laboratory all day, while Song Yao is still in the dormitory, occasionally bringing things over, waiting for him to move things together.

"I have already laid the cotton wool. You can go to sleep directly if the experiment is late in the future." Song Yao nodded slightly, knowing that Xu Qingzhou was busy.

Moreover, she really liked the feeling of decorating the home little by little with her own hands.

Xu Qingzhou smacked his lips. Is this the feeling of having a girl by his side? He didn't have to do anything, just lie down and enjoy it. It was a bit cool.

"I'm leaving on the 28th, do you really have nothing to bring?"

Song Yao shook her head: "No."

She didn't say one thing: she had everything... he just needed to bring himself back.

Sun Qingli glanced at the boy reading by the window when he spoke, originally wanting to see if he should change seats with Xiao Ran, seeing Xiao Ran sitting next to another boy, very unhappy.

Read! {

Wrote a quarter, the rest is ready to be written after the business trip.

Hmm, steady.

Explain the concept of the Cramér conjecture, clearly define the Cramér conjecture, give its standard expression, and briefly introduce the mathematical concepts and theories related to the Cramér conjecture.

Xu Qingzhou smacked his lips, so cold, it looks really busy.

"Okay, okay." Sun Qingli nodded with a smile. Anyway, there is still a week, no rush.

"It's quite good here." Ran Na smiled and took out her fruit phone, preparing to punch in and take pictures.

"Fine."

After a while, he looked around at the environment, and said to himself with some regret: "Unfortunately, we bought the tickets in a hurry, and there were no tickets, otherwise we should have bought business class."

In the proof of the Twin Prime Conjecture, it is still smooth, using the sieve method + function mode, using functions to make up for the defects of the sieve method.

Song Yao: "Hmm."

Xu Qingzhou just finished Song Yao's call, just about to read the information on the Cramér conjecture, and received a call from Professor Gu Zhizhong again.

"Professor Gu... hmm, okay, I know... contact Wang Wang Shixiong Zhao Zheng after getting off the plane."

Ran Na could only smile perfunctorily: "Let's talk about studying abroad later, this time it's mainly for relaxation."

【selberg noticed \sum_{d|n}\mu(d)】

Moreover, this boy also looks a little handsome.

This person talks a lot and likes to pretend. If it weren't for the fact that traveling alone is really boring, she wouldn't want to be together.

However, Xu Qingzhou's thoughts were soon interrupted by the chattering voice of the boy next to him.

This makeup took 1 hour to get out. Don't say such a little brother, even a salaryman who has been tortured by society for a long time will not refuse the request of such a beautiful sister.

Sure enough, the other party's message jumped out: "Pay attention to safety, call me when you arrive."

Xu Qingzhou was still thinking about the Twin Prime Conjecture, automatically shielding the surrounding noise, and suddenly felt someone poke his arm.

Next, Xu Qingzhou spent a week writing the report, and also rehearsed all kinds of questions and difficulties that might be encountered to ensure that he could respond freely at the report meeting.

【This article reports a proof of a long-unsolved problem in the field of mathematics—the Cramér conjecture. Since the Cramér conjecture was proposed, it has been in the field of number theory...】

During the period, he also started his own thesis, titled: The Influence of Spatial Walk-off on the Compression Characteristics of Quantum Optical Frequency Combs.

Sun Qingli sat down, his tone full of emotion, "Universities in China now, the environment is not good, and the ones taught are all nerds, completely incomparable to foreign countries."

!.

For such a long-distance trip, Ran Na likes to lean against the window, the space is relatively large, and she doesn't have to be too close to Sun Qingli.

Ran Na had already been a bit impatient, but still kept a smile on her face, and nodded from time to time. He stood still, feeling that walking like this was a bit missing, and planned to continue waiting for Song Yao's news.

At 8:50 AM, Xu Qingzhou boarded the international flight to London, starting a long 11.5-hour journey. The funding from the School of Mathematics was very sufficient, business class, but Xu Qingzhou only bought an economy class ticket. Finding his seat, he took out the information on the Twin Prime Conjecture from his schoolbag.

She was very confident that the boy in front would agree.

He knew that what Xiao Ran hated were those nerds.

"Glasgow University is recruiting many international students these years. With your grades, there is no problem at all." Sun Qingli continued.

But seeing the pile of messy things in the other party's hand, he felt relieved.

After rebirth, the first time going abroad.

"Xiao Ran, studying abroad for a master's degree is definitely the best choice."

Xu Qingzhou nodded with satisfaction, replied "Okay," and carried his suitcase to the subway.

Seeing that the girl didn't take it, Sun Qingli planned to test it, and then joked: "Or apply for our University of Glasgow, we can also take care of each other."

Half a month ago, Academician Xu Shihui brought students to communicate here.

By the window, Xu Qingzhou frowned slightly, his fingers tapping his arm.

Based on Xu Qingzhou's understanding of her, it is estimated that there is really none.

A senior brother named Zhao Zheng came to pick him up.

He turned his head and saw the girl tucking the broken hair beside her ear, looking at him with style, "

After Xu Qingzhou left the dormitory, he messaged Song Yao, who was in class, to tell her he was leaving.

Sounds approached from afar, followed by a thick scent of perfume. There was a rustling movement beside him as a girl sat down next to him, while another young man took the aisle seat.

By 8:30, Xu Qingzhou was already at Beijing Capital International Airport; this flight was primarily from Beijing Capital International Airport to London Heathrow Airport.

When busy with experiments, papers, and writing academic reports, time seemed to be on fast-forward. March passed quickly, and in the blink of an eye, it was March 28th.

After eating, the two didn't linger together; Xu Qingzhou went straight to the library, while Song Yao returned to the dormitory to rest, as she had classes all afternoon.

Early on the 28th, in Dorm 101, Xu Qingzhou packed his things, said goodbye to his three "adopted sons" in the dorm, and set off for the airport.

Every time, it felt like something flashed through his mind, but he couldn't quite grasp it—much like the feeling of being at the Great Perfection stage described in novels, on the verge of a breakthrough.

The report formats for mathematics and physics are similar.

On the side of the Jingda School of Mathematical Sciences, Academician Xu Shihui was invited to attend this conference, and Zhao Zheng was Academician Xu Shihui's student.

To be precise about living with the school beauty, the days of cohabiting with Song Xiaohua were postponed until he returned from his business trip.

The most important part is the methodology, detailing the proof methods and ideas he adopted; this can be roughly divided into five subsections, each corresponding to a key step or sub-problem.

In the library, Xu Qingzhou opened the document, preparing to write the academic report on the Cramér conjecture.

Hearing this, Xu Qingzhou gave him a faint look, shook his head, and shifted his attention back to the materials in front of him. There were too many people like this—the moon abroad was always rounder than at home—and he couldn't be bothered to argue anymore.

【Therefore, when n=1, it takes 1, and at other times it is 0; thus, as long as \lambda_1 is not less than 1, the formula for the sixth step determined by the arbitrary real sequence {\lambda_d} can become the required upper bound.】

Just as she expected, a warm smile appeared on the boy's face.

"Not changing."

"Thanks."

The other "thanks" stuck in Ran Na's throat. She stared at the boy in front of her in astonishment, a voice popping up in her mind: "What are you talking about?"
