Zhou Yu'an finished the TOEFL test last month, with a score of 112, one point higher than Ou Ye, his English has always been good, and he participated in the IMO in the UK a few years ago, and Zhou Yu'an acted as Shen Qi's temporary translator.

The GPA is also 4.0, and Zhou Yu'an is an excellent student.

According to the 100-point system, the average score of Zhou Yu'an's professional courses is 0.8 points lower than that of Ou Ye.

It is not difficult for Zhou Yuan to apply for an American university, but the difficult thing is an offer from Princeton.

Compared with Ou Ye, Zhou Yu'an's scientific research experience is limited, and he is currently working on a project with Sun Erxiong, the project code name SOZ, and the results have not yet been published.

Ou Ye is also a member of the SOZ project team, and Ou Ye will always be overwhelmed by Zhou Yu'an in terms of scientific research experience.

If it is similar to Shen Qi's season, the Princeton Department of Mathematics only recruits one graduate student in China in a season, then Ou Ye and Zhou Yu'an, two classmates, form a competitive situation, and there is always a priority for who goes to Princeton.

Zhou Yu'an's pressure is not small, and he regards Shen Qi as an academic catch-up target.

"Take care, force the king, goodbye. Zhou Yu'an hugged Shen Qi goodbye, six simple words, the first two words convey blessings, the middle two words carry hope, and the last two words let go of dreams.

Shen Qi took the flight to leave Hong Kong and return to Princeton.

Life has to go on, and there is no end to academic learning.

In order to let his family and beloved live a better life, Shen Qi must not stop and must move forward bravely.

In the first semester of graduate school at Princeton, Shen Qi chose to take 16 courses.

In the last two months of the first semester, Shen Qi focused most of his energy on important research topics such as the Walsh conjecture, the ζ of the Riemann Zeta function (2n+1), and the characterization of the Orbifold group embryonic embryo, resulting in him only completing 10 of the 16 courses, and the remaining 6 courses were delayed until the second semester.

Shen Qi got 80 credits for 10 courses, and the results of the project "Proof of the Walsh Conjecture of the Diphantom Equation Equation" were researched and verified by the Department of Mathematics of the University of Liberal Arts, and finally converted into 70 credits to Shen Qi.

Then Shen Qi got 150 credits in the first semester through the combination of course study + thesis publication, which is still 75 credits away from the goal of 225 credits for the master's degree of the Department of Mathematics of General University.

Tao Zhexuan and Yun Wei received their master's degrees in only two semesters while studying at Princeton, which is very amazingly efficient.

Because of the curriculum of the Department of Mathematics of the University of Mathematics, as well as the verification and publication cycle of mathematics papers, Shen Qi felt that it was the limit to get a master's degree in the Department of Mathematics of the University in two semesters, and Tao Zhexuan and Yun Wei's fastest records could only be equaled and could not be refreshed.

Harvesting a master's degree in the Department of Mathematics of the University in one semester, this kind of super-god-like performance, it is difficult for the god of mathematics to do it, unless it is the resurrection and rebirth of the mad demon Ora in his heyday.

It is generally believed in the mathematical community that among the four main gods, Euler has the fastest hand speed, the most diligent update, the best body, the most energetic, and the most single-minded.

The number of papers published in his lifetime is less than half of Euler's, but there are as many as 110 theorems and formulas in mathematics and physics named after "Gauss", which is more than twice that of Euler. Gauss only makes high-quality products, creating a brand reputation of the Göttingen School for hundreds of years.

Newton was the most erudite and knowledgeable, and his strengths and weaknesses were equally obvious, he had a genius brain and a more utilitarian mortal heart.

Archimedes was the most imaginative, his most legendary but the most tragic of all, when he was stabbed to death in his home by a Roman nobody.

The portrait of the four main gods of mathematics, Shen Qi hung in his apartment in Princeton, and he set a new medium and long-term plan for himself with the four main gods as his idols, the four major awards as his goals, and the four major journals as the cornerstone.

Of course, Princeton's PhD needs to be obtained as soon as possible, Shen Qi has held meetings in the United States and Hong Kong, and it is a bit embarrassing for the high-end mathematics circle in these years to not have a doctorate title to support the façade.

"In this way, in the second semester, I only need to publish a paper in the four major journals and complete a course to complete a master's degree and a Ph.D. ”

The paper on the ζ of Riemann zeta function (2n+1) was jointly drafted by Shen Qi and Mary, and submitted to the Annals of Mathematics, the most prestigious and IF of the four major journals.

Months have passed, and the paper is still peer-reviewed, and there seems to be no progress.

After returning from Hong Kong to win the award, Shen Qi was in a brave state and full of inspiration.

The unpopular topic "Orbifold Basic Group to Characterize Xin Orbifold Group Embryo", which once almost forced Shen Qi into a neuropath, has now made new progress.

Shen Qi completed this subject independently, his hand speed was fast, he was very diligent in renewal, his body was burning, and his endurance was long-lasting.

"Ora possessed!"

Shen Qi picked up the lantern and fought at night, and the pencil was broken twice.

"Obviously, {,}g is well defined and satisfies bilinearity, antisymmetry, Jacobian and Leibniz identities!"

"I have a bold idea!"

"Let g=(G0,G1),h=(H0,H1) be group embryos, and through smooth mapping processing, theoretically I can get an orbifold Poisson map!"

"I have a bolder idea!"

"If the orbifold basic group of g is trivial, and the orbital space ∣g ∣ = G0/G1 is the connected topological space, then ...... Rule...... Then?"

Shen Qi, who was at the top of his life, came to an abrupt end, and the most critical moment suddenly couldn't come out.

"Whew...... That's the end of today's work, all in all, a major breakthrough has been made in the subject of orbifold. Tomorrow I will ask Professor Müller for advice. ”

Trembling to the extreme, you will be empty and tired for a while.

The shivering is even more exhausting and depressing.

Shen Qi was tired, took a bath and slept, it was already two o'clock in the morning.

In the history of mathematics for thousands of years, orbifold is very young, and the concept of orbifold only appeared in the 50s of the last century, it cannot be regarded as an independent branch, it is a new theory produced by the intersection of topology and differential geometry.

After decades of development, orbifold theory involves many branches of mathematics and physics, such as topology, algebraic geometry, string theory, etc.

"Professor Müller, I am now facing a problem, if the orbifold basic group of g is orbifold is ordinary, and the orbital space ∣g∣=G0/G1 is a connected topological space, I want to get an orbifold fiber connected and orbifold single connected existence, how to deal with it?" Shen Qi threw out this topic at Professor Müller's regular academic meeting.

"Shen Qi, congratulations on winning the Chern's Mathematics Award, amazing boy. Cherry was a great mathematician, and I had meetings with him more than once. Mueller did not immediately answer Shen Qi's academic doubts.

"Thank you. Shen Qixin said, doesn't Old Man Muller understand?

"I think we should solve the problem of the Riemann Zeta function ζ (2n+1) first", Shen Qi, after all, you are one of the participants. Mueller said.

"Okay. Shen Qi nodded, and said, "But are there any other topics that need to be discussed in the Problem of the ζ of Riemann Zeta Function (2N+1)?" We have submitted it to the Annals of Mathematics and are currently under review. ”

"Of course there is a problem, it was rejected and needs to be overvised. Mary Xian's distress, she is also one of the authors of this paper.

"What sad news. Shen Qi was hit, and he put a lot of effort into this paper on analyzing number theory.
