I Just Want to Be a Quiet Top Student

Chapter 623 You, you, and you

Zhao Tiangan laughed twice: “Hey, studying and playing.”

“Then let’s study together.” Ou Ye walked to the blackboard and carefully observed the deduction formula on the blackboard.

“Sister Ye Ye sit.” Zeng Han pulled the chair behind Ou Ye.

“Yeah.” Ou Ye sat down.

“Sister Ye Zi drink water.” Xiaoyun poured a cup of hot water and handed it to Ou Ye.

“Thank you.” Ou Ye took the glass and didn’t drink it, just warmed his hands.

Tick ​​to tick, time goes by.

Ou Ye didn’t speak, and the three students were silent.

This may be their way of research.

For a long time, Ou Ye asked: “Xiao Zhao Baoyan came to our hospital, right?”

Zhao Tian nodded again and again: “Yes, yeah, I really want to choose Sister Ye Zi as my master’s tutor, but Sister Ye Zi, you don’t have students recently, so I can only choose Professor Liu.

“Oh, Professor Liu is a good teacher, he is very good at group theory.” Ou Ye said, she turned to ask the other two people: “What is your grade point?”

Zeng Han and Xiaoyun said in unison: “40.”

“Oh, excellent.” Although there are not many members in the club where Ou Ye is the instructor, all members are the elite of the students.

After a few brief chats, Ou Ye stopped talking. She focused on the mathematical symbols on the blackboard.

A teacher and three students just looked at a blackboard quietly.

After a long time, Ou Ye stood up, and she erased the chalk on the blackboard, leaving only a lonely line: e(q) is an infinite set. The necessary and sufficient condition is l(e, 1)=0.

Prove this sentence, that is, prove the bsd conjecture.

But in fact, “e(q) is an infinite set if l(e, 1) = 0” is not the form when Birch and Swinnerton-Dale first proposed this conjecture. They originally made the assumption. In the mathematical sense, it is stronger than this sentence, which is the so-called strong bsd conjecture.

The line on the blackboard is a weak bsd conjecture, and the three students are shocked. Did Ye Zijie find a breakthrough from the weak bsd conjecture?

Ou Ye continued to write below the weak bsd conjecture:

l(e,s)=(s-1)r higher-order terms

The strong and the weak are clear at a glance. Of course, the following equation is stronger, which is the expression of the strong bsd conjecture.

Whether it is strong or weak, it is not difficult for outstanding students in the mathematics department to understand the bsd conjecture.

Ou Ye hesitated for a while, and finally erased the weak bsd conjecture, leaving the strong bsd conjecture.

“Let’s do this.” Ou Ye knocked on the blackboard.

“Sister Ye Zi, what do you mean by doing this?” Zhao Tian asked.

Ou Ye: “Prove it.”

“Prove the strong bsd conjecture?” Zhao Tian was stunned.

Ou Ye: “Yes, we prove it.”

“Sister Ye Zi, do we mean?” Xiaoyun asked.

Ou Ye: “You, you, and you, plus me.”

“Sister Ye Zi, you are really playing!” Zhao Tian thought he had heard it wrong.

Ou Ye was puzzled: “You three, is it fake?”

Zhao Tian was a little incoherent: “I… I, I, I… what I just said, the three of us who studied the bsd conjecture is a joke! Just talk about me, I also studied p vs. np, I believe Professor Shen I must have studied these issues. Studying it does not mean that we must prove it… We just watched it, and never thought of conquering it.”

Zeng Han, who hadn’t spoken all the time, suddenly said: “Brother Zhao has already secured research. Senior Sister Yun and I have nothing to do. It is better to follow Sister Ye Zi and learn the skills to prove strong bsd conjecture.

I easily brushed my grade point to 40, and I am not interested in dating. Zeng Han and Xiaoyun are really fine at ordinary times, so Xiaoyun applied for the Hong Kong and Macau Pass. Zeng Han wrote and wiped the blackboard here every day. Various academic problems.

Ou Ye stared at Zeng Han. This thin, tall, unsmiling big boy seemed to have the calm and calm temperament of a science student compared to Zhao Tian who was bluffing.

Zeng Hanxian was a little uncomfortable being stared at by sister Ye Ye so straightforwardly. He smiled shyly, and the small dimples on his cheeks were looming.

Suddenly, Ou Ye said: “Xiao Zeng, I remember you, you are the 15-year-old gifted child who recommended Yan Da.”

“I dare not call a genius, I just know how to do questions.” Zeng Han scratched his head, looking silly.

“Are you underage this year?” Ou Ye asked again.

Zeng Han said: “A few months before reaching 18 years old.”

“Excellent.” Ou Ye nodded.

I don’t know if it’s because 15-year-old recommends Yan Da to be great, or under 18 years old is great. Anyway, Zeng Han is very happy to be praised by Sister Ye Zi.

Ou Ye knocked on the blackboard again, and said: “You three want to do it, just follow me. If you don’t want to do it, just forget it.”

Zeng Han was the first to express his position: “I will do it with Sister Ye Zi.”

Xiaoyun then raised her hand: “I will do it with Sister Ye Zi, too.”

The younger brother and younger sister are determined. As the senior and the president of the Ouye Computer Society, Zhao Tian can’t remain indifferent.

Zhao Tian stood up and said, “Count me!”

So in this ordinary day, a frail female mathematics professor took three undergraduates and launched a formal attack on the bsd conjecture, one of the millennial problems.

Ou Ye determined to solve the strong bsd conjecture, which is understandable.

Ou Ye needs an assistant, which is understandable.

It is understandable that the assistant is a doctoral student or a master student.

However, Ou Ye’s assistant is three undergraduates… well, one of them is a postgraduate student.

Even if you count Zhao Tian, ​​a prospective graduate student in the Department of Mathematics, Ou Ye’s assistant is still not strong enough.

At least it seems so.

How did Ou Ye think about it?

She has been observing this morning.

l(e, s) can be extended into a function that gives an answer to any complex number s, and the calculus method can be applied to this function. This means that l(e, s) can be represented by the famous Taylor polynomial.

So the strong bsd conjecture can actually be expressed as: The necessary and sufficient condition for e(q) to be an infinite set is but for n=0,……,r-1, each coefficient n is 0, Here r is the rank of e.

Another more intuitive description is that counting the number of zero terms at the beginning of the Taylor polynomial provides a measure of the degree to which the function is zero at the relevant point.

So another way of saying the strong bsd conjecture is that the rank of e gives an accurate measure of the degree to which l(e, 1) is zero.

The three undergraduates had a “fun” meal on the blackboard, which has touched the core part of the strong bsd conjecture.

This is Ou Ye’s observation and conclusion.

Things like mathematics, you can see talent at a glance.

Zhao Tian, ​​Xiaoyun, and Zeng Han may be vague in terms of the overall situation, but they are smart enough, talented enough, and focused enough on mathematics. These three students are big and young, but none of them are in love. They think math is much more interesting than falling in love.

Near noon, Ou Ye said to the three students: “Everyone, go eat first, and gather here in one hour.” (https://)
