Chapter 338: Long-term plan
The next day.
After everyone had breakfast, they stayed at home and played games all morning. It was not until noon that Guo Ziyang and Ding Jiahui prepared to take the subway after finishing last night's leftovers.
At the subway entrance, Ding Jiahui reluctantly held Song Yao's hand: "Yao Yao, I'll come and play with you next time."
When we were chatting in high school, we said that since we were all in Kyoto, we could see each other often, but now we only date once every month or two.
"Let's go shopping together next time." Song Yao nodded, with a look of reluctance in her eyes.
"Well, we're going to go shopping all day!"
Xu Qingzhou and Guo Ziyang stood aside, listening to the two girls arranging the next activities. They suddenly had a headache and could not fully appreciate the joy of shopping.
After saying goodbye, Guo Ziyang and Ding Jiahui walked into the subway entrance.
"Tian Yansi asked me to help him get something."
Ding Jiahui said unhappily: "Let him take it by himself, stay in the dormitory by himself, and let him take things every day, and we don't go to the backstreets."
She was worried that Guo Ziyang was being led astray by a grown boy who did nothing but stayed in the dormitory playing games every day.
"How should I refuse?" Guo Ziyang handed the phone to Ding Jiahui.
“I don’t know how to refuse now.”
Ding Jiahui hummed softly, took the phone, and muttered while typing: "Weren't you very good at speaking yesterday?"
"That's right."
"."
Guo Ziyang was punched by Ding Jiahui.
In the distance, Xu Qingzhou looked at Guo Ziyang who was being beaten, and said to Song Yao: "Look, classmate Ding Jiahui has been led astray by you."
"If you also want to get fucked, just tell me directly." Song Yao said.
Xu Qingzhou coughed slightly, and the two friends disappeared at the subway entrance. He took Song Yao's hand and put it in his pocket, asking: "Do you want to go back first or go for a while to soak up the sun?"
"Go shopping for a while." Song Yao exhaled a puff of white hot air.
On weekends, pedestrians walked slowly on the road, without the rush of the past. The coldest month of January has passed. In late February, the temperature has increased significantly, but the cool wind blowing on the face is still a bit chilly.
However, the sunshine was good today, which dissipated some of the chill. The branches on both sides were still bare. The sun's rays shone through, and the shadows of the trees swayed on the old wall.
Song Yao has long hair draped on both sides, delicate facial features, a red scarf around her neck, and a brown coat. Coupled with her slightly cold face, she is enough to instantly kill all the beauties on the Internet who have a sense of first love.
Noticing that her face seemed a little tired, Xu Qingzhou asked with a smile: "Didn't you get a good rest last night?"
"Yeah." Song Yao nodded, wondering if she was used to sleeping with this guy every day and woke up several times last night.
"You can't sleep without me holding you."
"No."
Song Yao would not admit that it was because of Xu Qingzhou, otherwise, with this person's mean character, he would definitely become arrogant again.
"Why is that?"
"Are you a hundred thousand whys?"
"Are you curious?"
"No!" Song Yao directly hugged Xu Qingzhou's arm and liked the feeling of just following Xu Qingzhou without having to think about where to go.
Xu Qingzhou thought that it must be like this. When he usually sleeps, this girl likes to hump against him.
The two of them walked and passed by an agency. Xu Qingzhou said with a smile: "After graduation and a job is confirmed, we can also buy our own house."
"Four rooms and one living room." Song Yao stretched out a hand to feel the temperature of the sun.
Xu Qingzhou pondered: "Are there too many rooms?"
"It's not much. We have one bedroom, a study room, and two guest bedrooms. Our parents can stay there when they come, when we have them."
Song Yao was talking about her big plan, but suddenly she got stuck.
"What are you waiting for?" Xu Qingzhou also stopped and looked at her, vaguely guessing what the school beauty Song wanted to say.
Song Yao looked away, looking at the shadow of the trees in the distance, and continued what she had just said: "You can stay here when other guests come."
"I don't think that's what you want to say."
"That's it." Song Yao was very sure. She spoke so quickly that she almost revealed the picture she had thought about the future life of the two of them. They were not even married, and having children was too far away.
Xu Qingzhou smiled and shook his head, thinking that this arrogant ghost had a lot to think about.
Song Yao put her hands back in her pockets, "I always feel that our plan will not develop as expected."
Xu Qingzhou nodded in agreement. When he was reborn, he only thought that he could live like those in those middle school novels every day. He never thought that one day he would live with a girl.
I guess Song Yao is like this too.
This girl used to say very proudly: "I don't want to fall in love before I graduate from college."
Look at it now, that's called a clingy person.
After wandering on the street for 20 minutes, the two went home.
Song Yao laughed, pulled Xu Qingzhou into the bedroom, and asked Xu Qingzhou to sleep with her.
Looking at Song school beauty who was already lying on the bed, Xu Qingzhou couldn't help but said: "Well, although we are still young, we don't have to be moderate."
"Come up quickly!" Song Yao raised her eyebrows and urged.
"Oh, okay." Xu Qingzhou climbed onto the bed obediently. As soon as he got into bed, Song Yao turned over and hugged him.
Smelling the familiar scent, Song Yao thought happily: "Compared with Jiahui, Xu Qingzhou is more comfortable to hold."
Xu Qingzhou was ready to be ravaged by Song School Beauty, but then he found that she had closed her eyes and was going to sleep.
He hooked the school beauty Song's calf with his foot.
When sleeping, school beauty Song likes to hint to herself like this.
Song Yao was indifferent.
Xu Qingzhou scraped his white and tender calves a few more times.
Song Yao still closed her eyes and just threatened: "If you dare to move again, I will beat you."
"."
Oh, my feelings are treated like a big warm baby by this girl.
Xu Qingzhou smiled, hugged the girl, closed his eyes, and prepared to take a nap.
February passed, and in early March, Kyoto once again experienced heavy snow.
Outside the window, large swathes of snow petals were falling down in the wind, and they were white, and there was a layer of ice flowers in front of the floor-to-ceiling windows.
Xu Qingzhou was sitting at the table, immersed in calculations.
There was already a pile of discarded manuscripts on the left side.
In the past four days, he has verified the method of obtaining some regularity on average completion time, and is currently looking for ways to improve the estimation of local smoothness.
Today, there are two mainstream research methods for estimating local smoothness of half-wave operators.
The first is to establish the square function estimation corresponding to the plate decomposition, combined with the Kakeya maximum function estimation method.
The second type is Wolff type separability inequality.
However, after a day of calculations, Xu Qingzhou discovered that when p is close to the endpoint 2n\n-1, the second separable inequality method is no longer so effective.
Therefore, he planned to use the first one, and he was also trying to establish a stronger square function inequality in the past few days.
After thinking for 20 minutes, Xu Qingzhou found a new path and wrote repeatedly.
Here, it can be roughly assumed that Z and F are smooth compact Riemann manifolds satisfying dimZ=3 and dimy=2 respectively.
Xu Qingzhou was busy writing. On the sofa next door, Song Yao was lying down with a blanket covered with a blanket. Ermeow was still lying on the radiator.
At 1:30 in the afternoon, seeing that it was almost time, Xu Qingzhou got up and poured a cup of hot water to send to Song Yao.
On the sofa, school beauty Song has woken up and is staring at the ceiling in a daze.
"Would you like to drink hot water?"
Song Yao shook her head.
Xu Qingzhou took a sip of water, pulled a chair and sat down in front of her, pulled out his soft hands from the quilt, "Are you feeling better?" Song Yao nodded slightly and said, "Well, much better."
I'm usually fine, but this month my period suddenly started to hurt.
Song Yao was completely bare-faced today, wearing a suspender skirt that exposed her small and delicate collarbones. She had just finished taking a nap, her hair was a little fried, and she felt more broken than before when she came to visit her aunt.
Xu Qingzhou felt a little distressed. It seemed like it really hurt. This girl was usually as energetic as if she had taken a fairy pill.
He reached out and pinched her delicate face. Although it was easy to get beaten, it could divert her attention.
Song Yao stared at the ceiling without moving.
She could already tell that this guy liked her weak look.
"With my weak expression, if I resist again, he might feel even more excited."
Huh~
Xu Qingzhou was greatly surprised. Normally the school belle from Song Dynasty would have glared at her.
He poked Song Yao in the face again.
Song Yao still didn't move.
He looked strange and said: "You don't want to fight?"
"Then you will feel more excited?" Song Yao said lazily.
Xu Qingzhou was silent for a long time, squeezed his little hands, and said seriously and solemnly: "I think you may really have misunderstood me. I am not a pervert."
Song Yao didn't answer, she just let out a "hmm" in her nose.
Xu Qingzhou shook his head helplessly.
Song Yao ignored the shocked Xu Qingzhou, turned to look out the window, and murmured: "The snow is still falling."
"This may be the last snow before spring. You bumpkin from the south who has never seen snow, shouldn't you commemorate it?"
"You are the bumpkin."
"I didn't know who it was at first, but even after it snowed, I was so excited that I was pulled out." Xu Qingzhou said leisurely.
"This is called romance."
"Romantic? So you have been plotting against me for a long time?"
"No." Song Yao replied with two words.
"There must be someone who has the toughest mouth in the whole body."
"It's obvious that you are plotting evil against me. You talk about sealing your heart with concrete. You often come to mess with me. When we go out to live, you start to set a trap for me. You pretend to be drunk to express your love."
Song Yao began to count Xu Qingzhou's crimes.
"Stop."
Xu Qingzhou interrupted and denied that Song Xiaohua had to go over all the old accounts.
He admitted: "I was wrong."
"As long as you know you were wrong." Song Yao was very satisfied with Xu Qingzhou's attitude.
Xu Qingzhou felt that he could not let the school beauty Song put all the blame on himself: "If you don't cooperate secretly, these little plans of mine won't be realized, right, Teacher Song~"
He deliberately emphasized the last three words, and then saw School Beauty Song pulling his hand over: "You"
Just when he was confused, the girl bit him on the arm.
"Hiss~Song Yao, you are really a dog!"
Although Xu Qingzhou bared his teeth, it actually didn't hurt, because the school beauty Song didn't bite her hard, and there was only a slight sting on her arm. The numbing stinging feeling was even a little comfortable.
Song Yao relented and glared: "Don't call me Teacher Song."
"Only the state officials are allowed to set fires and the people are not allowed to light lamps." Xu Qingzhou sighed, looked at the two neat rows of tooth marks on his forearm, thought about it, and said, "I want to bite it back."
"You want to be a spoiled child." After hearing this, Song Yao subconsciously covered her chest.
It took several days for the marks from the last time I was bitten by this guy to fade away.
Looking at Song Yao's movements, Xu Qingzhou fell silent, realizing that in the eyes of Song Yao's beauty, he seemed to be a complete pervert.
"What am I going to do? Jie Jie Jie, what do you think."
Xu Qingzhou's eyes darkened, as if he was about to take action.
"Xu Qingzhou!"
Song Yao was a little anxious.
It's broad daylight.
Sometimes it's so weird. I feel fine in bed because I do other things, but once I'm alone, I find it's very perverted.
Xu Qingzhou didn't tease her, "I'll rub your belly for you."
He put his hand on School Beauty Song's belly and rubbed it gently.
"I'll go to Academician Chu's place later, you can do it yourself."
"Teacher Xu, I'm just here to be your aunt, and I'm not disabled." Song Yao muttered.
Xu Qingzhou helped Song Yao rub her belly for a while, got up, cleaned up briefly, poured a cup of hot water for Song Yao, and went out with the computer and manuscript paper.
Outside the window, the snow was still falling. Song Yao sat cross-legged on the sofa, holding a cup and taking a sip of hot water.
Chatting with Xu Qingzhou and letting him rub his belly made me feel much better.
"However, although this guy is being mean-spirited because he wants to divert my attention, but... humph, write it down first and deal with it when I feel better."
Several courtyards.
"Ah sneeze~"
As soon as he entered the office, Xu Qingzhou sneezed and couldn't help but sigh: "Who missed me? I just met the school beauty Song. It should be Ms. Wang and the others."
"Xiao Xu, the temperature has dropped drastically. Be careful of catching a cold." Chu Jiangfeng motioned Xu Qingzhou to sit down.
"Hey, it's okay. I'm wearing thick clothes. Where is Senior Brother Yang?"
Chu Jiangfeng said: "He is going to Shanghai to hold a seminar and will come back tomorrow."
Xu Qingzhou smiled and nodded, sat down, and took out the manuscript containing the problems encountered during this period.
The two simply calculated directly on the blackboard next to them.
"Have you tried using localization and translation methods?"
"I have tried, through calculation, to find a standard form of the phase function that has a suitable local coordinate system that satisfies conditions (H) and (H)."
Xu Qingzhou asked questions in Chu Jiangfeng's office, and the two of them didn't finish until 4 p.m.
After the discussion, Chu Jiangfeng said regretfully: "Xiao Xu, the issue of local smoothness is not my research field. I don't have much advice for you. You still need to explore it yourself."
"You have helped me a lot."
Xu Qingzhou said sincerely.
For example, this afternoon, the two discussed the different forms of evolution of half-wave operators in the sense of local coordinates, and he benefited a lot.
Chu Jiangfeng said with a smile: "However, this thing is closely related to other conjectures in the field of harmonic analysis. You can find relevant information on the Bochner-Riesz summation and its derived maximum Bochner-Riesz conjecture."
"I'll look for it when I get back." Xu Qingzhou nodded.
"You don't need to be too stressed. You're new to this field. It's not that easy to get results. It's still the same as what I told you at the beginning. You are not required to publish many papers."
Chu Jiangfeng paused and continued: "Of course, just the paper on Polignac's conjecture is enough, not to mention a master's degree, even a doctorate."
"By the way, have the schools where you study abroad thought about it carefully?"
"I prefer MIT." Xu Qingzhou said.
Chu Jiangfeng thought for a moment and nodded slightly, "The academic atmosphere of mathematics in this school is very strong, which is very suitable. What about the doctoral supervisor?"
"I haven't thought about this yet."
Chu Jiangfeng smiled and said, "Don't worry, it's still early. I think many mathematics masters would like to have an outstanding student like you."
At 4:30 in the afternoon, Xu Qingzhou came out of Shuyuan, went to the vegetable market, bought a chicken, and took it back to make soup for the school beauty of Song Dynasty.
