Chapter 407

The location of Xu Qingzhou and Song Yao's apartment is quite good. Standing by the window, one can see the brilliant Charles River in the distance, especially on such weekends, there are more people by the river than usual.

Looking further, one can see the brilliant city stretching into the distance, finally disappearing into the skyline.

Xu Qingzhou came out after washing the dishes, and Song Yao was reading at the desk, her expression cold, with an expression of 'don't come disturb me'.

He shrugged, but didn't feel discouraged.

How does the saying go, as long as the effort is deep, the iron pestle can be ground into a needle.

He had already seen Song Yao through; this girl is a paper tiger, the more she puts on this look, the more empty she feels inside.

Wait slowly.

Thinking this, Xu Qingzhou sat at the table, took out the manuscript from the morning, and focused his attention on the thing in front of him.

Actually, Siegel had already proven in the 1930s: in the range that cannot be effectively calculated, the Landau-Siegel zero does not exist.

But his proof is incomplete.

For example, in a certain range, if the premise is that only one Landau-Siegel zero exists, since there are many functions, one already has a zero, the other functions don't have zeros...

If a larger range is given... then all functions have no zeros.

In short, assumptions were used inside.

By setting an upper or lower bound, this inequality can ensure that the distribution of prime numbers under given conditions satisfies certain mathematical laws.

After some effort, Xu Qingzhou had already successfully finished writing the second inequality and entered the writing of the third inequality.

This third proposition inequality is different from the first two; it is not used to prove or argue things about prime numbers, but to connect the logical chain between the first two inequalities and the Landau-Siegel zero conjecture.

This inequality can be used to prove that if a Landau-Siegel zero exists, it will cause one or some conditions in the first two inequalities to be unsatisfied, thereby triggering a contradiction.

Song Yao was indeed a bit panicked.

This pervert Xu Qingzhou keeps making strange requests...

Leading her to be led astray as well.

While despising those behaviors, she would actually give birth to a sense of excitement and anticipation.

Song Yao's hand writing stopped, and she began to worry again. Thinking back, if Xu Qingzhou dared to make these requests before, she would definitely have hammered him.

It's only been three years, and she's already been corroded.

Or rather, she fell into the pit Xu Qingzhou dug, although... she herself enjoyed it.

She propped up her chin and looked openly at her boyfriend; this guy is actually quite handsome when he's serious, indeed very charming...

As for Xu Qingzhou, he was already used to the school beauty Song's double standards. If he stared like this, she would have threatened him with her fists. Moreover, this girl was still in a special period, so having some strange ideas was very normal.

Saying more leads to more mistakes, so it's better to keep silent.

"Aren't you panicked?"

Xu Qingzhou had seen through Song Yao, and Song Yao had seen through Xu Qingzhou just the same; this guy just wanted to wait for her to take the initiative, so he could make some kind of request.

"Haste makes waste."

Xu Qingzhou was thinking about the calculation steps and said subconsciously, but instantly realized something was wrong.

"Can I explain?"

"What do you think..."

Time passed slowly.

The night sky was exceptionally clear, the bright moonlight was like the Milky Way spilling, splashing white waves on the vast earth; at this time, the whole world seemed to quiet down.

Xu Qingzhou was writing brush-brush, on the manuscript were complex formulas, someone used their foot to scrape their own calf.

"Are you seducing me?" Xu Qingzhou asked.

"Che." Song Yao che-ed, muttering: "Accidentally touched it."

Xu Qingzhou said "Oh", tapped his temple with the pen tip; although he is an old pervert, he does serious things when he needs to, thinking about the last formula describing the quantity of prime numbers in a specific interval.

Song Yao closed her notebook, reminding: "12:00, time to sleep."

"10 minutes." Xu Qingzhou answered. Song Yao stepped on slippers and returned to the bedroom.

Xu Qingzhou finished writing the formula in five minutes, packed up, dived into the quilt, hugged Song Yao in his arms, smelling the faint hair fragrance, "Sleep, good night."

Although he was seen through, those who wish to be hooked will be hooked.

"Mm."

Song Yao secretly breathed a sigh of relief; Xu Qingzhou didn't seem that impatient.

That's good, she could sleep normally.

10 minutes later.

The bedroom was pitch black.

Song Yao opened her eyes, moved uneasily, and said in a low voice: "If you want to... I can help you."

Heard that boys can't hold it for too long, it's bad for the body.

No errors in the content, keep reading!

"How to help?"

Song Yao turned back and glared at Xu Qingzhou: "Xu Qingzhou, don't go too far!"

It's this question again, what 'how to help'.

Creak~

In the dark night, Xu Qingzhou turned over and came on top.

Two pairs of eyes met. Touching the boy's scorching gaze, Song Yao's heart skipped a beat; that sense of tension and excitement surged up. She wanted to struggle, but her hands were already pinned by Xu Qingzhou.

Xu Qingzhou smiled and lowered his head.

A long time later.

"Xu Qingzhou, if you dare... you're dead."

The girl's eyes were moist; although she was shouting threatening words, her voice was soft and glutinous, without a hint of threat.

Sunday.

Xu Qingzhou had just finished washing up when he was pinned to the sofa by Song Yao and beaten up properly, to avenge the hatred of this guy "forcing" her last night.

In front of the desk, Song Yao's expression was still sour.

Xu Qingzhou lay on the sofa, one hand covering his waist, his hair also messed up by Song Yao; sure enough, happiness has a price.

After a long while, he stood up.

First, reply to Richard's email, explaining his progress here, such as having already constructed the wave function model, and next planning to try to see if he can find different data from other abnormal peaks.

Richard's side plans to combine two quarks into a diquark, and then consider the interaction between the diquark and the remaining quark and antiquark.

Starting from a physics perspective, hoping to find traces related to the abnormal peak from the quarks around the abnormal peak.

After Xu Qingzhou finished replying to Richard's email and confirmed the next work, he honestly stood up to cook.

In the afternoon, he spent two hours writing the lesson plan for the "Prime Number Gaps" course.

Monday afternoon, there was a class. Professor Roberts and Holen flew to Cambridge a few days ago, and the heavy responsibility of teaching fell on Xu Qingzhou.

Actually, generally, teaching assistants basically just help handle some homework, or answer some questions.

But this class is just an elective course, so Professor Roberts threw this matter directly to Holen, but he would occasionally go to the classroom to answer students' questions; this time he was completely playing the role of a hands-off manager.

The Academic Affairs Office had no opinion at all.

Who is Xu Qingzhou? To a certain extent, it can be said that in this world, there might not be many young scholars who understand prime numbers better than him.

Him coming to teach, the school has already earned it, okay.
