Chapter 354

Ying Shu Li Jiani: "Then again, there is really a question that needs your help from the teaching assistant!"

Li Jiani was not joking when she was >, but she really had a problem to ask others to solve.

It was an assignment from their real function and functional analysis teacher last week.

She first pondered alone with a pen for half an hour, but did not figure it out.

Later, after asking my roommates, I also found that everyone would.

There is no way, Li Jiani can only ask the top student in the class, but the result is...... Neither will they!

This makes Li Jiani very uncomfortable!

As for the seniors and seniors, Li Jiani is not familiar with them.

Besides, since the math bosses in his class have said that they can't solve it, even if he just finds a senior senior, it is difficult to say that he can give the answer.

Coincidentally, Cheng Nuo said so in the group chat, and Li Jiani thought of this stubble.

One is to help me solve math problems, and the other is to test whether my young teaching assistant is really as young and talented as rumored!

"Send me the question and I'll take a look at it for you. Cheng Nuo didn't finish his words.

If he said that he would be 100% sure of it, then Li Jiani's classmate directly threw him in the face with a Goldbach guess, what should he do?

Let's wait for the topic to come out!

"Teaching assistant, wait for me in a while, I'll take a picture of the topic and send it to you. Li Jiani replied.

In a few seconds, Li Jiani posted a picture in the group chat.

Cheng Nuo clicked it open with a little apprehension, and after a second, exhaled lightly.

"How is it, can you solve it?" asked Li Jiani in an uncertain tone.

"Wait for me for a minute. ”

After Cheng Nuo finished sending this paragraph, he directly closed his mobile phone and put it on the table.

Then, I opened the notebook on my desk, tore off a random sheet and used it as scratch paper, picked up a pen, and wrote formulas on the paper as if I were handy.

The topic, Cheng Nuo has already seen it, and it is a very routine topic.

Of course, this convention is compared with the Riemann conjecture, the four-color theorem, and the Goldbach conjecture.

Cheng Nuo was really worried that Li Jiani, a little girl, would come up with a world problem that would make him unable to get off the stage in front of more than 100 people.

But fortunately, Li Jiani should be regarded as sincere in seeking advice.

[Please prove that if (X,τ) is the second linear topological space, (Y,||.) -||) is a linear norm space, if TnX→Y(j∈J) is a family of continuous mappings, and ...... To everything j∈J, there is T, U∈V.]

This is a topic that belongs to the field of functional analysis.

The difficulty of the questions is there, but that's only for ordinary outstanding students, and for Cheng Nuo, hehe......

It can only be said that it is not even a plate of appetizers.

He had long since lost interest in such low-level and interesting topics, if it weren't for the sake of pretending to be ......

Rub, said leaked.

If it weren't for answering questions, you would think Cheng Nuo would solve this kind of problem.

The tip of the pen is like a swimming snake, swimming quickly on the paper.

After all, it was said that it would be done in a minute, and if it was not written because there were too many formulas, it would be really embarrassing at that time.

And in the group, after Cheng Nuo posted the message of "wait for me for a minute", the group also began to discuss.

Ying Shu Wu Yong: "One minute? The teaching assistant won't go to the arithmetic tool, right?"

Shutong Li Yunteng: "Just take paper and pen, why did it take so much time, I think eighty percent went to the toilet." ”

Ying Li Jiani: "I don't know if the teaching assistant can handle such a difficult topic?"

Ying Shu Lu Qiu: "It should be possible." I consulted a graduate student at noon on this question, and he just replied to the message saying that he had a clue and estimated that he would be able to solve it tomorrow. If you ask Assistant Teacher Cheng to come, it should be done in an hour!"

A minute passed.

In the group, Cheng Nuo first sent a message: "It's done!"

Got it?

Seeing the three words, everyone in the group was stunned for a while.

However, when I saw the picture posted behind Cheng Nuo's text, I was shocked one by one, and my mind cleared up all of a sudden.

No, it's only been a minute?!!

They all thought of that possibility, their fingers trembling, and they hesitantly clicked on the picture.

What catches your eye is the chic and heroic word "proof" written in a black carbon pen.

Below, a series of formula combinations.

That's the specific proof step.

[Since Λx∈X , the set {Tjx;j∈J} is (Y,||.) -||) , so Λx>0, ns<0, and ......]

Line by line, step by step.

Cheng Nuo wrote the solution ideas very clearly, even their group of Tsinghua undergraduates, after reading one side, they could thoroughly understand Cheng Nuo's proof ideas.

At the same time, I also know whether Cheng Nuo's proof process is correct or not.

One minute, according to Li Jiani, it was only a minute after the question was sent to him!

The current demons are all so perverted!

How can we live in the same era as him!

Cheng Nuo didn't look at the "terrifying" comments of the classmates in the group.

After playing a few games, Cheng Nuo climbed into bed and went to bed.

Tomorrow, there is one more thing waiting for him, not too big or small.

............

The next day, in the morning.

Today is an important day for students at many universities around the world.

Because at this time of the year, the winners of the American Collegiate Mathematical Contest in Modeling will be announced on the official website.

Subsequently, the certificates and medals will be shipped from the headquarters of the Mathematical Association of the United States to universities around the world.

Early in the morning, Cheng Nuo was called to the office building of the Institute of Mathematics and sat in front of a computer with several teachers who looked like leaders.

At 10:00 Kyoto time and 22:00 rice country time, the official website of Meisai announced the list of winners of the major awards.

This time, Tsinghua School of Mathematics is naturally going for the O Award.

For them, one O award is more important than ten F awards and M awards.

Tick tock, tick tock!

The hour hand keeps turning, and it gets closer and closer to that point in time.

Tick!

Ten o'clock sharp.

The dean of the Department of Mathematics glanced at Cheng Nuo behind him, took a deep breath, opened the official website of Meisai, and opened the "List of Winners" column.

The awards are listed in descending order.

First there were twenty O awards, then F awards, and then M awards.

The internal rankings of the awards are in no particular order, and the list is arranged in alphabetical order.

The head of the mathematics department looked at the first column of the O Prize.

The winning team is from Harvard University, and the topic is topic B, and the name of the paper is ......

The second column is from the University of Oxford.

The third column is from the University of Porphy, Degu.

............

He glanced at the line, but he never saw the familiar name of the school. He sighed in disappointment, but his gaze froze suddenly.

In the eighteenth column of the O Award, he saw the familiar school and name.

Winning team members: Cheng Nuo, An Yang, Shi Qi

Nationality: Huaguo

School: Tsinghua University

Topic selection: Question A

Title of Paper: "Research on the Model of Overtaking in One-way Driving Lanes"
