Chapter 334 Today is destined to be difficult Since the 22nd, Xu Qingzhou's life has become quiet again. He occasionally attends two academic seminars, and spends the rest of the time in the hotel doing calculations, or making soup on the phone with the busy Song Yao. The afternoon before I returned home, it was just getting dark in Jerusalem. That day, Xu Qingzhou was standing in front of the window, talking on the phone with the school beauty Song about making soup. At 1 . Kyoto time, Song Yao had just finished taking a shower and was lying on the bed ready to rest. She said pitifully, "Teacher Xu, I'm so tired." This is what happens after the two people get to know each other. School Beauty Song is no longer the cold and arrogant goddess. Whenever she is extremely tired, she will act coquettishly with Xu Qingzhou. Xu Qingzhou also felt a little distressed, and said softly: "When we get home, I will make you something delicious." Song Yao was indeed very busy these past two days. Li Daiyue did not treat this girl as an undergraduate student. After the meeting on the first day, he assigned her the task of studying the comparability issues of Penguin Video's financial analysis. Draw a performance graph, analyze competitors' business models, and finally conduct a penetration analysis. Although it looks simple, this research report is actually almost as difficult as a doctoral thesis. School beauty Song is smart and quick-witted, but she still seems to be struggling.
The two chatted for a few more minutes, and seeing that Song Yao was already sleepy, he said, "Okay, go to bed early, see you tomorrow." "Well, Mr. Xu, good night." "Good night, Mr. Song." When Xu Qingzhou called her "Teacher Song", Song Yao woke up from her sleepiness and glared at her and warned her: "Xu Qingzhou, don't call me 'Teacher Song'." The word "teacher" easily makes her think of something bad. It's just that the sofa is a little wet, she's not the only one with it. "I understand, Teacher Song." Xu Qingzhou always likes to seek death, especially when Song Yao can't deal with him. Song Yao gritted her teeth, but she couldn't do anything about her boyfriend who was far away, so she could only snort and threaten, "Just wait for me." The two hung up the phone. Xu Qingzhou refilled his coffee and stopped by the window to rest. The dusk deepened, and the city in the distance had already lit up with brilliant lights. Further away was a commercial street that looked quite lively, and stars could already be seen in the night sky. "Phew~ Last night here." Xu Qingzhou took a sip of coffee, sat down at the desk, and focused his attention on the calculations in front of him again. Today's content involves the local smoothing effect of the half-wave operator in Euclidean space, so I got stuck. The optimal Lp estimate must be calculated first. Based on the optimal Lp estimate, the space-time estimate must be derived, that is, for all t in a certain time interval, the integral of the Lp norm after the half-wave operator acts on f satisfies a certain estimate. In short, it is a bit complicated, which is one of his shortcomings. Xu Qingzhou quickly got into the state. Here, we can assume that f is the Schwartz function, the Cauchy problem of the wave equation. υ can be expressed using the half-wave operator: 【u(x,t)t^ S f + e~it'/^ f ).】
After a while, Xu Qingzhou shook his head, frowned, and took away the manuscript paper. There was something wrong with the calculated result. The night passed like this. the next day. At the entrance of Penguin Building, Wang Yijuan said, "Lao Li, Xiao Song, the company has arranged a hotel for you, just stay here for two days before leaving." "No, there are still many things in the research group that need my attention." Professor Li smiled and shook his head. The most important thing is that this girl is rushing back to see her boyfriend. Although I have always advised Song Yao not to be too obsessed with love, what can I do? I have to pamper my students. Wang Yijuan sighed: "You, I've known you for decades, and you've always been so busy, not giving yourself any time to rest." Li Daiyue did not comment and said, "Next time you come to Kyoto, I will treat you to a meal." Wang Yijuan nodded and looked at Song Yao: "Xiao Song, are you interested in working at Penguin after graduation? Don't worry, I can give you three times the salary according to the industry standard." This young girl is a talent. Although she is only an undergraduate, her working ability is better than those of the old employees who have worked here for more than ten years. "cough~" Li Daiyue coughed and stared at Wang Yijuan unkindly. "You want to poach my apprentice? No way." "No, thank you Mr. Wang, I want to focus on my studies right now." Song Yao shook her head. Wang Yijuan shook her head regretfully. She had been mentally prepared. If Lao Li kept her by his side at this time, it must be that he wanted to take her as his last disciple. She added: "No matter what, the door to Penguin is always open to you." "Xiaoyao, let's go." Li Daiyue called Song Yao to get in the car, and decided in her heart that the things she had just said about treating her to a meal were gone. Thousands of kilometers away. At 26:6 in the morning on the th, Xu Qingzhou and his group boarded the flight back home. The first-class cabin was sold out, so they directly booked business-class tickets. In order to choose a window seat, Xu Qingzhou was not sitting with Chu Jiangfeng and the others, and there was a row of seats between them. Compared to the first time, the surroundings were much more lively this time. Because there were two young girls next to Xu Qingzhou, chattering non-stop, and there were also three boys sitting side by side on the right, all young people. However, looking at Xu Qingzhou, the three boys had some envy in their eyes, and they wished they could switch places with Xu Qingzhou. There is a feeling of pity for their misfortune and hatred for their lack of struggle. There were two beautiful girls next to him, but instead of taking the opportunity to chat with them, he just went to sleep. When the time came, the plane began to taxi on the runway. Xu Qingzhou pulled the hood of his sweatshirt over to cover half of his face, and prepared to take a break at this time. Last night, he stayed up until 3: in the morning to solve the problem of the half-wave operator in Euclid space.
He also made a fatal mistake. School Beauty Song sent a photo of breakfast, and he subconsciously took out his phone to comment. Although he reacted quickly and didn't reply, the fact that "the other party is typing" exposed the fact that he was staying up late. Then, I saw the familiar words: "Just wait for me." It's not going to be a good day going home today, it's bound to be a bit dangerous. As he sighed, Xu Qingzhou's consciousness gradually became blurred. Next to Xu Qingzhou was a girl with long hair and heavy makeup. She was pretty. Next to her was a little girl wearing glasses, with a bun and a bit of baby fat. She was secretly looking at Xu Qingzhou. The boy had already sat down when they got on the plane. Judging from the half of his face that was exposed, he must be a handsome guy. Too bad I can't see his face. "Still looking? You've lost your soul." Seeing that her cousin was still peeking at the boy by the window, Liu Dongxuan reminded her in a bad mood. "Sister Xuanxuan~" Peng Jingqiu is acting coquettishly. Seeing that Xu Qingzhou was sleeping, the two girls consciously lowered the volume and gathered together to select photos from that period. "I need to do some work first." Peng Jingqiu held the phone. When he found that the two beauties had already chosen their photos, the boy on the right side of the aisle took the initiative to strike up a conversation with them, “Beautiful ladies, are you here for a trip?” Peng Jingqiu nodded and replied, "Yes, I've been here for more than ten days." "We are the same. We are taking advantage of the winter vacation to go out for a walk." Huang Haoyu said with a smile. This cute girl is not very old, probably a freshman or sophomore. The beauty next to her is much more mature and is also his target. Peng Jingqiu's eyes lit up, revealing her surprise at finding like-minded teammates, and asked, "You are students too?" Huang Haoyu smiled and nodded: "Yes, the three of us are from Kyoto Sports University, what about you?" Peng Jingqiu said directly: "Kyoto Normal University." Liu Dongxuan didn't say much, thinking that her cousin was still too naive and could be easily tricked into revealing things. The following topics were easily opened up, from school to daily interests and then to travel destinations. Sitting in the front row, listening to the laughter coming from behind, Yang Yongze shook his head helplessly and said with emotion: "Young people are still passionate." Chu Jiangfeng also smiled and nodded. They were all old. They used to be able to be energetic after taking a flight for more than ten hours, but now, their waists and eyes would hurt after sitting for a while. Wang Lin stroked his reading glasses, glanced in Xu Qingzhou's direction, and joked, "Not entirely. Look at Xiao Xu, he's already falling asleep." "This kid is just like Old Gu, very steady." Chu Jiangfeng also said with a smile. Yang Yongze took a look and said: "He really fell asleep. I was just asking you a question about prime numbers. Teacher, how about you..." "You guys." Chu Jiangfeng shook his head and said unhappily: "Ask your junior brother later. We old bones are not like you. We can withstand the torment." Yang Yongze laughed and said, "Then you two should have a good rest."
Long-distance flights are commonplace for Xu Qingzhou. When he woke up, the plane had leveled off. Next door, a few young people were chatting happily. Well, I almost forgot, he is a young man himself. "Sure, I definitely want to go to southern Xinjiang. Maybe we can go together then. It will be more fun with more people," said Huang Haoyu. Peng Jingqiu pulled Liu Dongxuan and said, "Okay, okay, we can still drive ourselves, right, Sister Xuanxuan." Liu Dongxuan was not very involved in the conversation, only saying a few words occasionally. This time she just smiled and said "hmm". She knew very well what the boy was thinking. The other party brought the topic to her several times and it was obvious that he was interested in her. But unfortunately, she has no intention of falling in love at the moment. These people are all too immature. However, when meeting strangers and chatting with them during the journey, at least Peng Jingqiu won't be so bored during the more than ten hours. "If you want to drive yourself, you've chosen the right person. Brother Yu is a certified racing driver." The boy next to Huang Haoyu joined in the conversation. "Racing driver?!" Peng Jingqiu's expression showed admiration. "Well, I am very interested in this kind of competitive sports." Huang Haoyu said with a smile, looking at Liu Dongxuan intentionally or unintentionally, hoping that this matter would attract Liu Dongxuan's attention. Girls who like to go out and have fun should be very interested in these. But he regretfully discovered that the girl he liked seemed to be paying attention to the boy next door who had just woken up. "Whoo~" On this side, Xu Qingzhou stretched, moved his neck, and drank a sip of water. He was not interested in the conversation of the people next to him. After moistening his throat, he looked out the window again, letting his thoughts slowly come back. Liu Dongxuan also noticed that Xu Qingzhou woke up. How should I put it? She found him more interesting than the two people next to him who were talking about how many places they had been to. She thought: "There seems to be a special aura about this boy." This was exactly what attracted her, a bit like the melancholy and cold male protagonist in the novels she had read before. Huang Haoyu, who was chatting with Peng Jingqiu, also noticed this scene. Compared with Peng Jingqiu, he still prefers a slightly cold and aloof sister like Liu Dongxuan, who inexplicably makes him feel more conquered. At this time, seeing that the girl he liked, Liu Dongxuan, had all her eyes on Xu Qingzhou, he felt a little unhappy. After staring out the window for 2 minutes, Xu Qingzhou retracted his gaze and took out the notes he had taken during this period from his bag. Oh, reading a book? Seeing this scene, Huang Haoyu, as a boy, like most boys, had two words popping up in his mind: "Pretend to be cool." Who reads on an airplane? However, seeing that Liu Dongxuan's focus was always on Xu Qingzhou, it was much more useful than his previous remarks about diving, Maldives and the like. He secretly said: "I learned it, this is a good way to attract girls. Many girls like literary style now." Liu Dongxuan had the same idea at first. This person wanted to attract her attention, but she soon realized that the other person was looking at her very seriously and still didn't seem to want to talk to her at all. At this time, she noticed a young man standing up in front of her, also holding manuscript paper in his hand. Everyone's eyes fell on the man who suddenly stood up. He was wearing glasses and was very gentle. The A4 paper in his hand was full of scribbles.
Huang Haoyu complained in his heart, "Damn, what kind of weird people are on this plane." The young man with glasses had come over and stopped in front of Peng Jingqiu. He smiled apologetically at Peng Jingqiu and Liu Dongxuan, then turned his gaze to Xu Qingzhou who was looking down at his notes. "Junior brother, junior brother? I have a question about the upper bound of the Riemann function. If you have time, please help me take a look." "it is good." Xu Qingzhou took off his hoodie, glanced at the question, smiled and nodded, "I'll give it to you later." Yang Yongze nodded, nodded apologetically to the several stunned young people around him, and returned to his seat. In front, Wang Lin said with a smile: "Old Chu, to be honest, I am a little jealous of you. Both of your students are good." One is a rare genius, and the other has also achieved considerable success and has not slacked off. Who wouldn't envy such students? Chu Jiangfeng was also reading the information and said with a smile, "You are envious, right? I wish I had asked you to supervise two doctoral students, but you thought it was too much trouble." "You are lucky. If I had met Xiao Xu and Xiao Yang, you would have thought I would accept them." Wang Lin said unhappily. Next door, several people were still in a daze. The information they had just received was too much to process for a while. Although Chu Jiangfeng and Wang Lin were talking in low voices, the plane was very quiet at that time, so every word was clearly audible. What kind of thing is it to just take two doctors to play with? These days, are even PhD students so worthless? (End of this chapter)
