Chapter 384: Boil the frog in warm water, take it slow 8 pm. After coming back from dinner outside, they were both exhausted. "I went to take a shower." Xu Qingzhou lay on the sofa for two minutes, then got up and prepared to take a shower. "Oh." Song Yao was still selecting the photos she had taken today and would send them to the group that included Ding Jiahui and Guo Ziyang. "Would you like to join us?" "Do not want to." Song Aojiao refused subconsciously. "Okay." Xu Qingzhou shrugged and went into the bathroom with his clothes.
"This guy" Song Yao raised her eyes and looked towards the bathroom. It was very wrong that they gave up so easily. There must be a conspiracy. Ten minutes passed. "It's your turn. I'll blow dry my hair myself." "okay." Xu Qingzhou stared at the back of School Beauty Song and thought secretly. As a hunter, you have to be patient. Children make choices about things like bathrooms and sofas, but adults want them all. As for the rest, we'll take it step by step. He looked away and stared at the ceiling in a daze. Graduated with a master's degree. Another small step in life planning has been completed. The next step is to study for a doctorate. He was sent abroad to study on a government scholarship or through joint training. After obtaining his doctorate degree from MIT, Peking University will also issue him a diploma. Kyoto University has already completed the docking work with MIT. Now he only has to consider the issue of a supervisor. There seem to be many mathematics masters at MIT, so he can take his time to consider it. Not long after, Song Yao came out of the shower. She had just taken a shower yesterday, so she didn't wash her hair and covered it with a shower cap. As usual, she leaned on the sofa and put her feet in Xu Qingzhou's arms. Seeing that he was in a daze, she rubbed her toes on Xu Qingzhou's belly a few times. "Want to play?" "That's right, I always feel like there's something important that hasn't been done yet." Xu Qingzhou came back to his senses and murmured.
Song Yao's eyes darkened and she rubbed Xu Qingzhou's thigh with her foot. "You're seducing me." "Bah! Shameless." Song Yao would never admit it. Xu Qingzhou narrowed his eyes and slowly fell on top of School Beauty Song. "Teacher Song, tonight. Hmm?" "No." Song Yao still refused, it was too messy. She avoided her boyfriend's burning gaze and paused, "At most, at most. I can take a bath with you." Xu Qingzhou smiled gently. From the sofa to the bathroom, hehe, boiling the frog in warm water, the plan is successful. For the following period of time, Xu Qingzhou was not so busy and he treated the three people in the dormitory to dinner on Friday night. Then I went to the library to read books, and Professor Zhao Shengwen later sent me some information about lithium batteries. In the past year, trams have experienced explosive growth. Although there is still a gap between them and what they will be in a decade or so, with support from the national level, the prospects are quite bright. While reading the materials, he was also thinking about which direction of research to pursue next. Without a doubt, it is the field of basic mathematics. You should first max out your mathematical skill points. At the same time, you can simultaneously advance other research while conducting mathematical research. Of course, when you are abroad, even if you do other research and experiments, most of them are theoretical content. Science has no nationality, but scientists do have a nationality. What he is thinking about now is the specific field he is working in. Most people follow their own supervisor's projects during their graduate studies, but Xu Qingzhou still likes the feeling of being in control of everything. After working hard for most of my life, I finally have my own say. Now I can't go back to the old ways. I don't need to consider algebra directly, I'm quite familiar with it. Does combinatorial mathematics study discrete structures? The properties and counting problems of sets, graphs, and arrangements can be skipped directly, I'm not interested. Or. Continue with the reconciliation analysis? Scattering theory of nonlinear dispersion equations, theory of fluid dynamics equations Xu Qingzhou considered the direction in his mind and shook his head again. He had just been working on it for more than a year, and it was Fourier again. After all, when it comes to harmonic analysis, it is related to Fourier. It mainly studies the expansion of functions into Fourier series or Fourier integrals, as well as various problems related to such series and integrals. According to Mr. Hua Luogeng, the operation of expanding a known function into a Fourier series is called harmonic analysis. In short, I'm a bit tired of it and need a change of taste. So, back to number theory? Xu Qingzhou thought about it and marked out all the points that could be advanced in the field of number theory. In the afternoon, the sun is shining brightly. "Whoo~"
In the library, Xu Qingzhou exhaled slowly and leaned back in a chair to rest. There is a mind map on the manuscript paper. Analytic number theory: the integral mean distribution problem of Hurwitz zeta-function; the weighted mean distribution problem of Dirichlet L-function. Algebraic number theory: function approximation theory and divergent series summation theory; fusion of topology and number theory. Topology was also ticked off and labeled "Poincaré conjecture." Also, the theory of prime number distribution. "Since we are back to number theory, then...is it possible?" Xu Qingzhou squinted his eyes, and a bold idea suddenly popped up in his mind. He took out a new manuscript and wrote four words on it - Riemann hypothesis. This is something that Academician Xu Shihui mentioned a few days ago. "Professor Maynard and his team have completed the recalculation of the new large value of the Dirichlet polynomial." This is actually also his credit. He proposed to transform the problem into a study of energy distribution based on the location of the large value points of the Dirichlet series, so as to achieve a more accurate estimate of the frequency of occurrence of large values. It seems that there is a lot of potential. Xu Qingzhou tapped the manuscript paper with the tip of his pen. "but" Xu Qingzhou was a little hesitant. Just as he had compared it before, the Riemann hypothesis was like the blueprint of the Eiffel Tower that appeared in the Stone Age. It was very grand in description, but it was just a castle in the air in the Neolithic Age. Of course, two years later, things are a little different. He solved the twin prime conjecture. The twin prime conjecture focuses on the distribution pattern of prime numbers, especially the existence of pairs of prime numbers whose difference is 2. The Riemann hypothesis focuses on the distribution of zeros of the Riemann zeta function, which are closely related to the overall distribution of prime numbers. The solution to the twin prime conjecture makes it possible to solve the Riemann hypothesis to a certain extent. Despite this, it seems that it is still a long way to fully solve the Riemann hypothesis. library. Xu Qingzhou twirled the pen in his hand, wondering whether he should continue to act stubbornly. "Xu Shen." Someone is shouting. He looked up and saw a little girl standing nervously in front of him. "Mr. Xu, can you give me an autograph?" The little girl lowered her voice, her face full of excitement. "can." The little girl immediately handed over a notebook. Xu Qingzhou wrote down his name with a smile.
"Thank you, God Xu!" The little girl returned to her seat with her notebook, and then started taking pictures with her mobile phone. Xu Qingzhou couldn't help but smile, he seemed to be more popular than in his previous life. "and many more." Xu Qingzhou slapped his head and cursed himself for being sick. "Damn it, I'm already reborn, why am I still tangling so much? I wonder if this is embarrassing for a reborn person." As a cheater, if I don't act willfully, this rebirth will be meaningless.
