Chapter 397: Let You Feel the Passion of Boston Women In the office, Xu Qingzhou sat down and greeted the white-haired old man: "Professor Roberts." Professor Roberts looked as tired as Horn. He couldn't help but sigh that these two were indeed master and disciple, as they both looked to be in poor spirits. Fortunately, there was the school beauty Song. otherwise I might become one of them, with dark circles under my eyes and thinning hair every day. "Welcome to MIT, please take a seat." Professor Roberts moved the manuscript on the chair and signaled Xu Qingzhou that he could sit down. "Try my hand-brewed coffee." Horn had already poured coffee for Xu Qingzhou and Professor Roberts. "Thank you." Xu Qingzhou thanked. "I assure you, I am better at making coffee than I am at doing math calculations." Horn said with a smile. Professor Roberts piled the manuscripts at his feet, took a sip of coffee, and said with a smile: "Horn's coffee-making skills are definitely the best in MIT. Many professors come over to ask for a cup of coffee during their breaks."
"It was delicious." After tasting it, Xu Qingzhou praised it, saying that it tasted really good. "It's a pity. If I hadn't studied mathematics, I would definitely have become an excellent barista." Horn sighed with pride. Professor Roberts put down his coffee and got down to business: "It's been a week since our last discussion. Are you still planning to study the Riemann hypothesis?" "Well, in life, you always have to do some challenging work." Xu Qingzhou took a sip and nodded. "I also studied the Riemann hypothesis when I was young, but..." Professor Roberts paused and said, "We are planning to do a project on linear algebra, specifically, large-scale matrix computing and its application in recommendation systems. If you are willing to come, I would welcome you." "Of course, you can choose the Riemann hypothesis, or work on other topics separately." Xu Qingzhou has learned about this topic. During this period, short video platforms are emerging, and the design of algorithms for efficiently processing large-scale sparse matrices, especially in recommendation systems, and how to use these algorithms to accelerate the similarity calculation between users and items and improve recommendation accuracy and real-time performance are indeed hot topics in the next few years. "Thank you for the invitation, Professor." Xu Qingzhou smiled and said, "I'd better try the Riemann hypothesis. You know, it seems to have a different kind of magic for those who study mathematics." Professor Roberts nodded slightly, understanding the young man's thoughts. Not only him, but even his mentor had tried it before, but in the end there was no result. He said: "I'm sorry that I may not be able to give you much advice on this subject, but if you want, you are welcome to discuss it with me." "Xu, you are very talented. I don't have too many rigid requirements for your graduation, and I won't interfere with your projects. But for your graduation thesis, I hope you can come up with a good result that at least meets the standards of Mathematical Inventions. I believe you can do this easily." Xu Qingzhou nodded, it was indeed not difficult. Professor Roberts smiled and said, "However, although I don't require you to participate in my project, there may be some work that you may need to do. Don't worry, it won't distract you too much." "What job?" Xu Qingzhou was not surprised by this, as it was common for doctoral students to help their supervisors share the work.
Before Professor Roberts could speak, Horn smiled and said, "Teaching assistant. My previous job was to occasionally give lectures to undergraduates. This should be easy for you." "Analytical prime number theory." Professor Roberts added. "no problem." Xu Qingzhou agreed with a smile. Horn joked, "Giving lectures often broadens your thinking. Xu, maybe you will suddenly solve the Riemann hypothesis while giving a lecture." "I hope I'll be that lucky." Next, everyone did not waste any time, and Horn accompanied Xu Qingzhou to go through the admission procedures. Unlike domestic universities, the campus, city and community of the school here are integrated with each other, with no obvious dividing lines. When walking on the street, you can indeed feel the strong academic atmosphere. The two crossed two streets and found the registration address written in the email, Room E18-172. Because Peking University has already been connected, the MID card number and Athena account are already prepared, so the procedure is very simple, just sign your name and confirm whether to stay in the hotel. Oh, and here’s the bank card number for the scholarship. Like school beauty Song, he has a full scholarship. The admission procedures are completed in about 10 minutes. "Xu, if I wasn't flying to damn New York later, I would definitely take you out for a drink." Horne chuckled and said, "Let me show you the passion of Boston women." "Drinking is fine, but women are not necessary. I have a girlfriend." Xu Qingzhou didn't want to be beaten up by the school beauty Song. "That's a shame. But we'll have a drink when we get back anyway." "Sure." Xu Qingzhou nodded with a smile. When the two came back, Professor Roberts handed Xu Qingzhou a pile of manuscripts, saying that they were his research manuscripts on the Riemann hypothesis and he hoped that they would be useful to Xu Qingzhou. Xu Qingzhou expressed his gratitude. Professor Roberts and Horn were in a hurry to catch their flight, so they left in a hurry, and Xu Qingzhou returned to the hotel with the manuscript. hotel room. Er Miao was lying on the windowsill with his head hung. He was much more miserable than Xu Qingzhou and the others. He had to sit on a flight for more than 20 hours and could only stay in a narrow cat bag. Seeing Xu Qingzhou coming back, Er Miao came over and rubbed his thigh, meowing. "Wait a minute, I'll feed you right away." Xu Qingzhou put down the manuscript. This stupid cat was probably hungry. There used to be automatic feeding machines, but now Er Miao’s belongings were left in Yandong Garden, and he needed to buy new ones after he settled down. He took out a plastic bowl from his schoolbag, poured cat food into it for Er Miao, and then sat down on a chair, intending to read the manuscript given by Professor Roberts first. During the few days on the road, he has figured out how to further analyze the Riemann hypothesis using an algebraic method. Next, he plans to use the method of analytical extension to expand the domain of the zeta function from real numbers to complex numbers.
In general, we must first understand what the Riemann hypothesis is. Er Miao was burying his head in the food, making a crunching sound. Xu Qingzhou then remembered that it was time for lunch. Song Yao was eating at school today, and he was too lazy to go downstairs. He just asked the waiter to bring a bowl of pasta while he opened the manuscript. After eating in a few bites, I continued to do my business. The first one is the application of Riemann hypothesis in integer distribution. It uses analytical methods to study the problem of integer distribution with a fixed number of prime factors, and applies Riemann hypothesis to give an estimate of the error term in its mean distribution. In the manuscript, the distribution of integers with a fixed number of prime factors is also studied. (End of this chapter)
