I just want to be a quiet scholar

Chapter 258 Equations
After staying in New York for a week, Ouye's parents are going back to China.

Before leaving, Lao Ou talked to Shen Qi alone.

Old Ou said: "Actually, I firmly oppose Ouye's coming to the United States, but she insists on coming, so I can only follow her."

Your objection is invalid, Comrade Ou, your wife has the final say.Shen Qi, who has grasped the main contradiction, is not afraid of Lao Ou now, Lao Ou is just a little monster, and Mrs. Ye is the core figure.

If you offend Lao Ou, at most you will be beaten.

If he offends Mrs. Ye, the real estate tycoon, Shen Qi may never see Ouye again in this life.

"Uncle Ou, please rest assured. I will definitely take care of Ouye with my life. She is your daughter and my girlfriend." Shen Qi solemnly made a promise that no matter what, Old Ouye is Ouye's father. You have to respect him even if you are not afraid of him.

"Hey, my daughter is old enough to have her own choice." Lao Ou leaned melancholy on a tree, took out a pack of Marlboro, took out a cigarette, took two puffs and then extinguished it: "American cigarettes are too difficult to smoke."

Old Ou's attitude was no longer so tough, Shen Qi struck while the iron was hot: "I will give Ouye the happiest home."

Old Ou asked: "Let's be honest, you and Ouye plan to return to China in a few years? You are both 22 years old this year, and you are not too young after finishing your studies."

Shen Qi said: "Actually, I can go back to China after I get a PhD from Princeton in September this year. The main reason is to see Ouye's study progress. When she wants to go back to China, I will go back with her."

"How did your kid study so fast? You have only been in the United States for less than two years. You can get a master's degree and a Ph.D. degree? It's so easy to get a degree from Princeton?"

"I don't have any special skills, Uncle Ou, I only know how to read."

"When I met you for the first time, I admired you very much. After seeing you a few times, I have some opinions on you. Although you have many problems, I admit that you are a genius in reading, and you are also a clever person. My only My request is that you must not bully Ouye or disappoint Ouye, otherwise I will not let you go." Old Ouhu's body shook, and he paid equal attention to kindness and power.

Shen Qi raised his finger: "I swear to mathematics, I only love Ouye in my life!"

"I swear it's a fart, you have to do it with your heart!" Lao Ou scolded, but he could also see that Shen Qi was sincere to Ouye.

Old Ou took out a Marlboro and handed it to Shen Qi. This was the first time he handed Shen Qi a cigarette: "Do you smoke?"

Shen Qi waved his hands and said, "No, no, smoking is harmful to your health. Uncle Ou, you should also smoke less."

"It's better not to smoke." Lao Ou put the cigarette back into the cigarette case, and asked again: "Do you drink?"

"Drink a little wine once in a while."

"Then I don't worry, eating, drinking, whoring, gambling, smoking, men have to be the same, if you don't like anything, and study like a saint all day, then I will think you have a big problem." Old Ou inspected Shen Qi The method is quite special, it can be regarded as the final trial, but it has to pass, Ouye has already come to the United States.

The next day, the old Ou couple left the United States. They will effectively supervise Shen Qi's promise through irregular unannounced inspections and phone spot checks.

Columbia University female dormitory, Ouye's room.

"Come on, give me a hug, Little Ye Zi." Shen Qi hugged Ouye a lot.

"Hmm...take a bath first...bad guy...my parents just left..."

"Did you know, Xiao Yezi, I'm going to name a new theorem soon, Shen's proximity theorem."

"Amazing……"

"It doesn't make sense for me to name a hundred theorems when you're not with me. Thank God, you're here at last. Let's make a Shen-Eu equation together, shall we?"

"Okay...what aspect?"

"You are the best at Diophantine equations, shall we start with Diophantine equations?"

"Well... today I can only solve... one-degree equations... more than two-degree equations... I can't do it..."

……

……

Shen Qi spent the night in Ouye's dormitory. The young couple hadn't seen each other for a year, and they were very affectionate, and there was no need to express if they had a good understanding in solving the equation.

Ouye's physical condition can only solve the equation once at most, Shen Qi knows Ouye well, he has a sense of proportion.

Skills The use of reasonable solutions to equations is conducive to strengthening the relationship between mathematical couples, and can also promote blood circulation and metabolism.

After dawn, Shen Qi took Ouye to meet Ouye's mentor Gong Changwei.

"Brother, it seems like your home stadium." Ouye held Shen Qi's hand, she was a formal student of Columbia University's Department of Mathematics, and Shen Qi was a family member of the student.

"I know Professor Gong very well. We have held meetings together. He was my reviewer. Walsh guessed that he passed the verification." Shen Qi and Ouye walked into the Department of Mathematics building of Columbia University hand in hand. Professor Gong Changwei, an expert in number theory, arrived.

"Senior Brother, Professor Gong Da, Ouye is counting on you. You need to guide her a lot in mathematics, especially in number theory." Shen Qi said.

"Your general university still needs to worry about the internal business of our brother university?" Gong Changwei laughed.

"The Ivy League eight schools are one family, you have me, and I have you." Shen Qi also smiled.

"Hi, Ouye, hello, we interviewed on video, we are not strangers." Gong Changwei greeted Ouye.

Ouye replied politely: "Professor Gong is good, please give me your advice."

Gong Changwei explained some of the basic academic requirements for graduate students in Columbia University’s Department of Mathematics, which are similar to those of Universities. Ouye needs to attend classes, assist research, and write papers. It can take one or two years at the earliest, and at least three to five years to obtain a master’s degree in mathematics at Columbia University.

After leaving the Department of Mathematics building, Ouye reluctantly said to Shen Qi: "Qi, you should hurry back to Pudong University, your studies have been delayed too much recently."

"The Ph.D. students at Pudong University are free-ranging. There is only one requirement, and they drink coffee every Wednesday." Shen Qi said, "But I still have to go back to Pudong University first. I have nothing to delay. What I am afraid of is delaying yours." Studies. After all, you are new here, and your studies are heavy, and you need to meditate for a while to find your academic status."

Ouye nodded: "Well, I will work hard."

"Then I'm leaving. I won't come to Columbia within a month. I'll come to see you in a month." Shen Qi kissed Ouye goodbye, and then drove back to Princeton.

It's more than an hour's drive from Princeton to Columbia University. It's not far or close. It's convenient if you have a car.

Shen Qi really has nothing to delay, he has already finished all the preparation materials for PSU's Ph.D. graduation before Christmas, and now he is waiting for his Ph.D. graduation defense.

Although there is no hard requirement, Shen Qi still wants to do something meaningful. He started to draft "History of Number Theory", which is his hobby and not a necessary condition for obtaining a PhD.

Number theory studies pure numbers, because of her pure and noble origin, she is known as the "Queen of Mathematics".

Number theory can be divided into two main branches, one is the study of the solution of equations, namely Diophantine equations, the history of this branch can be traced back to about 2000 years ago, the founder is Diophantus, a great Greek mathematician.

Masters such as Fermat, Andrew Wiles, and Faltings have all made contributions in this field. The famous Diophantine equations include Fermat's last theorem, Catalan's theorem, and BSD, the first two of which have been proved , BSD is crazy hard, one of the seven millennium problems.

The Walsh conjecture proved by Shen Qi also belongs to the Diophantine series of equations. The Walsh conjecture was renamed Walsh's theorem a year ago and can be directly quoted.

Another branch of number theory is analytic number theory, which was jointly founded by Gauss, Riemann, Euler, Dirichlet, Weyl and other masters.

Famous cases in analytic number theory include Gaussian triangle sum theorem, Euler's pentagonal number theorem, Dirichlet's proof of two prime number problems, Weyl's exponent sum formula, Goldbach's conjecture, Riemann's conjecture, etc.

Most of the well-known problems in analytic number theory have been solved, leaving only Goldbach's conjecture and Riemann's conjecture to be overcome.

Shen Qi tried to gain a deeper understanding of Diophantine equations and analytic number theory from the perspective of the history of number theory.

Forcibly attacking until you vomit, it is better to find some inspiration from the mathematics masters in history.
