Chapter 335 Song Yao’s trump card
The cabin was slightly quiet.
Xu Qingzhou took off his hat, which allowed several people around him to see his appearance clearly.
Peng Jingqiu stared at Xu Qingzhou with wide eyes. His hair was messy and did not meet her requirements for a delicate boy at all, but he was indeed handsome and seemed familiar.
Liu Dongxuan had a similar expression. She thought the man looked familiar, but she couldn't remember it for a while.
Xu Qingzhou nodded to the two people beside him. He didn't care about the scrawled hair now, but looked at the calculations on the manuscript.
It's a bit like the problem he once told his schoolmates in the question and answer room about using complex analysis to prove the prime number theorem.
Both involve the need to extend ζ(s) into a meromorphic function on the right half plane.
After thinking for a moment, Xu Qingzhou already had an idea to use the open covering principle to establish a series of ordered points on γ for finite open covering. Then use Euler's summation formula) Let f be differentiable on [m, n].
Here, Xu Qingzhou has already begun to write, because s=1 is the extreme point, and there are
[|ζ(s)|=|h(s)1]
Analyzing in the neighborhood, we can get: [ψ(x)≥∑p≤xlog(p)≥∑xα≤p≤xlog( p)≥(π(x)π(xα))log(xα)】
Lines of complex calculations appeared on the blank manuscript paper.
Peng Jingqiu stared at Xu Qingzhou for a long time, and seemed to have thought of something. Her eyes widened, and she excitedly grabbed Liu Dongxuan's hand and said, "Xu Qingzhou, sister Xuanxuan, she is Xu Qingzhou!"
Liu Dongxuan paused for a moment, her eyes filled with astonishment, realizing that this boy really seemed to be Xu Qingzhou!
Xu Qingzhou was still immersed in calculations, but at this time he was pulled out of his thoughts by the excited voice, and looked at Peng Jingqiu with an excited expression in confusion.
"Are you Xu Qingzhou?" Peng Jingqiu's small round face was full of excitement.
"Yeah." Xu Qingzhou nodded.
“Sister Xuanxuan, it’s really Xu Qingzhou!”
Peng Jingqiu excitedly held Liu Dongxuan’s hand and looked at Xu Qingzhou, “I grew up listening to your stories”
< br>
Xu Qingzhou: "."
Why did you grow up listening to my stories?
He reminded: "I'm only 19 now."
Peng Jingqiu finally realized that she had a language problem, blushed, and quickly changed her words, "I said it wrong, I said it wrong, I'm listening to you The story of getting through the difficult senior year of high school!"
"As long as it helps you," Xu Qingzhou smiled softly.
Liu Dongxuan was shaken by Peng Jingqiu, and she came back to her senses at this time. When she met Xu Qingzhou's gaze, she was hit in her heart.
Oh, it turns out he is Xu Qingzhou.
She secretly looked at the appearance of the boy next to her. Well, he was much more handsome than the photos she saw on Weibo.
The hair is a little messy, but this undoubtedly makes his lazy temperament more attractive.
Peng Jingqiu was still excited and said: "Well, Xu Shen, can we take a group photo?"
"Okay."
Xu Qingzhou did not refuse.
Peng Jingqiu raised her phone and took a few photos along Liu Dongxuan's path.
Next door, Huang Haoyu twitched the corner of his mouth, and just wanted to say: "Damn it, so what you are playing is true?"
Looking at the three people taking pictures together, and With emotion, if it were Xu Qingzhou, everything would be reasonable. He is not pretending to be cool, but he is awesome.
After Peng Jingqiu took the group photo, she looked at Xu Qingzhou pitifully: "Xu Shen, can you reserve a WeChat friend seat?"
"Waiting until we get off the plane."
"Thank you, Xu Shen! ”
Xu Qingzhou was freed from Peng Jingqiu’s enthusiasm and focused on the calculation just now.
After a brief interlude, the previously lively and lively atmosphere suddenly died down, and the cabin became somewhat quiet.
Huang Haoyu was a little bit shocked. Compared with Xu Qingzhou, he seemed weak.
"No, compared to Xu Qingzhou, 99.99999 people in this world are weak."
Thinking about it this way, he felt much better.
Peng Jingqiu and Liu Dongxuan did not speak, fearing to disturb Xu Qingzhou's thoughts. Peng Jingqiu looked away from Xu Qingzhou from time to time, looking at the completely incomprehensible calculations on the manuscript paper with adoring eyes.
Liu Dongxuan was much more reserved. Although she felt a little fluttering in her heart, it was not as obvious as her cousin.
20 minutes passed.
Xu Qingzhou stopped writing and had already solved the problem that Yang Yongze had just asked. He had written two large pages of manuscript paper. He raised his head and glanced in the direction of Yang Yongze.
Peng Jingqiu was sitting on one side of the aisle. Seeing that Xu Qingzhou wanted to hand the manuscript to Yang Yongze, she took the initiative and said, "I'll help you."
"Thank you." Xu Qingzhou thanked him.
Peng Jingqiu seemed to have taken over some important task, with a calm expression, holding the manuscript paper in both hands, a few steps away from delivering the manuscript, and suddenly walked out of a different sense of ceremony.
Xu Qingzhou took out the bottle and wanted to drink water, but then he remembered that the bottle was empty.
"Drink mine." Liu Dongxuan handed the water in front of her to Xu Qingzhou. Seeing Xu Qingzhou stunned for a moment, she hurriedly said: "I have never drank it."
"Okay, thank you. ."
Xu Qingzhou smiled.
11 hours passed like this.
Read information, sleep, eat, three points and one line.
After more than ten hours of flying, not to mention people in their fifties like Chu Jiangfeng and Wang Lin, even Xu Qingzhou suffered from back pain.
“Xu Shen, goodbye.”
Peng Jingqiu waved at the airport gate.
"Goodbye." Xu Qingzhou smiled and nodded, and he and Chu Jiangfeng got into the car sent by the school to pick them up.
Peng Jingqiu sighed: "It's great, we actually met Xu Qingzhou!"
"Yes, we met Xu Qingzhou." Liu Dongxuan murmured, looking in the direction where the car disappeared.
What girl is not pregnant?
Xu Qingzhou fulfilled all her fantasies about the male protagonist in the novel.
However, she also knew that the possibility between them and Xu Qingzhou was not high, not because of the difference in status, but because Xu Qingzhou seemed to already have a girlfriend, and the person on the screen saver was very beautiful.
"After I got back, I sent it to Moments. Hey, Uncle Meng came to pick us up."
"Let's go."
Xu Qingzhou got off the car at the gate of the community and said goodbye to Chu Jiangfeng and the others. , pushing the suitcase and walking towards the community.
It was already 12 o'clock in the morning, the twilight was thick, and there were only sparse vehicles on the streets. The noise during the day was replaced by silence at this time.
In the north, it is still very cold in February, especially at night.
Squeak~
Xu Qingzhou pushed the door open and walked in. Suddenly, the aroma of food came, and the second cat squatted on the shoe cabinet, meowing non-stop.
“Miss me?”
Xu Qingzhou held Er Miao in his arms and pushed the suitcase into the house with one hand.
As if hearing the noise, Song Yao leaned out of the kitchen with a spoon and looked at her boyfriend: "Wash your hands and get ready to eat."
Xu Qingzhou put down the two cats and felt inexplicably moved in his heart. When he came back from a business trip, his home was warm and he could eat delicious food. This is how people live their lives.
“What are you doing Xu Qingzhou, the apron is covered with oil!”
In the living room, Xu Qingzhou gave Song Yao a big hug, “I don’t dislike you.”
"I really want to beat you." Song Yao muttered. Although she said this, she still enjoyed the feeling of being in her boyfriend's arms.
The long black hair carries the unique fragrance of shampoo and Song school beauty. The hair is a little moist, and it is immediately clear, "She has just taken a shower."
Xu Qingzhou noticed it and couldn't help but press his head into the school beauty Song's neck.
Song Yao moved uneasily a few times. The hot breath made her hand holding the spoon tremble slightly, "Itchy~ Xu Qingzhou, are you a dog?"
< br>"Don't you bite me often."
The two hugged for a while, Song Yao pushed Xu Qingzhou away, "Hurry and wash your hands." "Okay." Xu Qingzhou went to the bathroom to wash his hands and helped Then pour out the pork ribs soup.
Braised pork, green peppers and stir-fried lotus root. Two people, three dishes and one soup.
I was on a business trip for a while and ate Western food every day. What I missed the most was the braised pork and white rice at home.
In one meal, Xu Qingzhou ate three large bowls of rice.
After eating and drinking, Xu Qingzhou leaned back on the chair comfortably, recharging his energy. He looked at the girl opposite and praised: "It's good to have a little cook at home."
"Hmph, who said yesterday that he would prepare delicious food for me when he came back?"
Song Yao raised her eyebrows. Seeing Xu Qingzhou enjoying it so much, she felt very happy and had a sense of accomplishment. She said to her heart: "No matter how good you are, your family still has to rely on me."
"It's not just food that can be eaten. "Xu Qingzhou whispered.
"Huh?" Song Yao looked unkind, suspecting that this guy was driving again.
Xu Qingzhou did not refute. He has always been in a state of "the enemy is strong and we are weak" in this family. He just needs to get used to it.
He stood up, "I'm going to wash the dishes."
As soon as he reached for the bowl, Song Yao slapped him away.
Song Yao said: "You go take a shower, I will wash the dishes."
Xu Qingzhou instantly understood what this girl meant, but this guy always likes to pretend, pretending not to understand: "What are you doing in the shower?" , I just washed it last night, hey, I’m so tired, I just packed up and went to bed.”
Song Yao squinted her eyes, and she could tell from the narrow smile in Xu Qingzhou’s eyes that this guy was pretending again.
Then don’t blame her for showing her trump card.
"Xu Qingzhou, are you dying?"
"."
Xu Qingzhou went to get clean clothes with a dark face.
In the living room, listening to the sound of running water coming from the bathroom, Song Yao curled up her lips and hummed a little tune to put away the dishes.
10 minutes passed.
Xu Qingzhou walked out of the bathroom and glanced around. He saw that the school beauty Song had gone back to the bedroom, and the second cat was wandering around in the living room with its tail swept.
Taking a deep breath, he turned off the light in the living room and walked towards the bedroom.
Inside, the school beauty Song has her hair tied up and is ready.
Sure enough, it was just as I guessed.
Tonight is destined to be a sleepless night.
Xu Qingzhou's eyes were firm and he strode towards the master bedroom.
Jiejiejie~
Today he wants to let the school beauty Song understand a truth, you can eat randomly, but you can't talk nonsense!
Bang~
As the bedroom door closed and the last light in the living room disappeared, Ermeow was not affected and nimbly jumped from the armrest of the sofa to the table.
Poof~
It seemed like someone was knocked down, and then the sound of Twolegs came from the bedroom.
"Song Yao, it's too much, come down!"
"No, I want to be on top."
"You are a girl, why do you always like me? On top, woo~”
Stupid Twoleg.
The sound coming from the bedroom made the second cat's ears twitch. He meowed twice in disgust, then fell from the table to the ground and walked slowly towards his little nest in the corner.
The sound is quiet there.
The first night home,
The next day, 9:30 in the morning.
Xu Qingzhou put his hands behind his head and stared at the ceiling in a daze. He slept very comfortably. The jet lag was no match for the fatigue that hit him, especially since he was back in a familiar and warm environment.
Finally home.
There has been some progress on the local smoothing effect of the Euclid space half-wave operator. The LP estimation has been completed and will be a little smoother next.
Perhaps, I will use this as my graduation thesis.
Then there are government-sponsored studies abroad.
Princeton, Cambridge, MIT
As long as he is willing, these schools will definitely extend an olive branch.
The first choice is still the United States. I have to say that the school is the first choice. He really wants to go to Princeton, where he is familiar with the school. The only difference is that he once studied physics, and this time he focused on mathematics.
Of course, now he needs to consider the future of the two. If possible, he would prefer to choose a school that is slightly closer to the school beauty Song.
Beside him, school beauty Song was sleeping soundly. This girl looked majestic in the first half, but in the end, he was the superior one and killed her so hard that she dropped her armor and screamed in agony.
The girl murmured, woke up, closed her eyes and squeezed in his direction.
The two people stuck together, and Song Yao asked: "What are you thinking about?"
"Study abroad." Xu Qingzhou did not hide it.
Song Yao still had her eyes closed, "Professor Li suggested that I go to Stanford or Harvard as an exchange student next year."
"The economics majors in these two schools are indeed the top majors. You Which one do you want to choose? ”
"Not sure." Song Yao closed her eyes and could feel the beating in Xu Qingzhou's chest.
Xu Qingzhou laughed and said: "Then I don't have to worry. I choose MIT and you Harvard. Both schools are in Cambridge, Massachusetts, USA. They are close to each other. They are only separated by a road called Charles River. "
This is a good choice. I vaguely remember that it takes half an hour to walk to the other school and 15 minutes to take a taxi.
Song Yao opened her eyes and lay on Xu Qingzhou, poking Xu Qingzhou's face, "Do you want to choose MIT?"
She was worried that Xu Qingzhou went to MIT for her. Science and engineering.
"You followed me to the United States." Xu Qingzhou said solemnly.
Song Yao understood what Xu Qingzhou meant. She followed Xu Qingzhou to the United States. Xu Qingzhou chose a school close to her. When two people are together, they have to consider each other.
“But.”
Although she also wanted to be with Xu Qingzhou, if he had another school that he liked more, she still wanted Xu Qingzhou to go to that school.
Xu Qingzhou smiled, pinched her face, and continued: "Nothing to worry about, MIT's mathematics is one of the best, and it is among my alternatives."
Song Yao held Xu Qingzhou's face and slapped him hard on the mouth: "Teacher Xu, thank you."
"Kiss me again when you wake up."
"Hmph , I just want to stink you." Song Yao groaned and lay back in Xu Qingzhou's arms, spreading her erect soft flesh on Xu Qingzhou's chest.
Xu Qingzhou gasped, the school beauty Song’s unintentional action was so provocative.
The clothes on the two of them had been thrown away long ago, and they could completely feel each other's every move.
Song Yao was still enjoying the warmth her boyfriend brought to her, but then her body suddenly froze and she got up and looked at him angrily.
“You, you.”
School beauty Song’s face was covered with a blush. She was so tired last night. How can this guy still hold on now?
"Natural reaction, who told you to move around on me, ah~"
Xu Qingzhou would not admit that he was a pervert.
When Song Yao saw this guy throwing the blame on her, she pinched the bad thing under her and got up from the bed angrily, "Get up!"
Lie down again to figure out the problem.
Today happens to be Saturday, and Jiahui and the others are coming to play today.
Xu Qingzhou was lying on the bed, "Some people like to do things like demolishing bridges in rivers. They like it when they need it, but they don't need it anymore. Woo~"
Song Yao just put on her clothes. After hearing this, he was so angry that he pinned the bitch on the bed and beat him up. However, as he was beating him, he found that the clothes he had just put on gradually fell to the ground.
In the living room, the two cats were chattering and lying on the nest with their heads drooped.
Twolegs, don’t let the cat sleep anymore!
