should be Li Jiani: "in other words, there is really a topic that needs the help of the TA!"

Li Jiani typed in the wechat group.

She's not joking, but she really has a problem to ask someone else to solve.

That's a homework problem left by their real variable function and functional analysis teacher last week.

First, she thought about it for half an hour alone with a pen, but she didn't come up with it.

After I asked my roommates, I found that every one of them would.

I can't help it. Li Jiani can only ask the Xueba in her class. The result is Neither will they!

This makes Li Jiani very uncomfortable!

Li Jiani is not familiar with senior students.

What's more, since the math masters in my class say they can't solve it, it's hard to say that they can give an answer even if they find a senior student.

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

One is to help me solve my math problem. On the other hand, I also want to test whether my young teaching assistant is really as young and talented as it is rumored to be!

"Send me the questions, and I'll take a look at them for you." Cheng Nuo is not full of words.

If he said that he would be able to solve it 100% of the time, what would he do if Li Jiani directly threw Goldbach's conjecture in his face?

Or wait for the topic to come out!

"The TA, wait for a moment. I'll take pictures of the title and send it to you." Li Jiani replied.

A few seconds later, Li Jiani sent a picture in the group chat.

Cheng Nuo a little bit uneasy to open, a second later, light breath.

"Well, can you work it out?" Li Jiani asked in an uncertain tone.

"Give me a minute."

Cheng Nuo finished this paragraph, directly shut off the phone, put it on the table.

Then, he opened the notebook on the desk, tore off a piece of paper as a draft, took up a pen, and wrote the formula on the paper like a brush.

The title, Cheng Nuo has already read it. It's a very regular topic.

Of course, this routine is compared with Riemann's conjecture, four color theorem and Goldbach's conjecture.

Cheng Nuo is really worried that Li Jiani, a little girl, takes out a world problem and makes him stand down in front of more than 100 people.

But fortunately, Li Jiani's classmate should be regarded as sincerely asking for advice.

[please prove that if (x, τ) is a second class linear topological space, (y, | - |) is a linear quasi normed space, if TNX → y (J ∈ J) is a family of continuous mappings, and For all J ∈ J, there is t, u ∈ v.]

this is a topic in the field of functional analysis.

The difficulty of the topic is some, but it is only for ordinary excellent students, and for Cheng Nuo, ha ha

Not even an appetizer.

He had no interest in this kind of low interest topic, if it was not for pretending to force

Wipe it. It's a slip of the tongue.

If it wasn't for answering questions, you thought Cheng Nuo would solve such problems.

The tip of the pen swims like a snake on the paper.

After all, it is said that it will be finished in one minute. If there are too many formulas to finish, then it will be really embarrassing.

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

Wu Yong: "one minute? Can't the ta go to the computing tool

Shu Tong Li Yunteng: "just take paper and pen, which used so much time, I think 80% went to the toilet."

Li Jiani should count: "I don't know such a difficult topic. Can the TA solve it?"

Should count Lu Qiu: "should be able to. I consulted a senior graduate student at noon about this topic. He has just replied to the message and said that he has a little clue. He is expected to solve it tomorrow. If you let TA Cheng come, it should be done in an hour! "

One minute, it's going to be over.

Within the group, Cheng Nuo first sent a message: "done!"

Done? What's done?!

Seeing the three words, the crowd was confused for a while.

However, when you see the picture behind the text of Cheng Nuo, all of them are horrified and startled, and the brain suddenly wakes up.

No, it's only a minute?!!

They all thought of that possibility, their fingers trembling, hesitant to open the picture.

What comes into view is the bold and unrestrained "proof" written with black carbon pen.

Here is a series of formula combinations.

That's the specific proof step.

Because ∧ x ∈ x, the set {Tjx; J ∈ J} is a bounded set in (y, || - |), so Λ x > 0, there exists ns < 0, sometimes 】

step by step.Cheng Nuo's idea of solving problems is very clear. Even if they are Tsinghua undergraduates, they can understand Cheng Nuo's proof ideas thoroughly after reading one side.

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

One minute, according to the question Li Jiani sent him, only one minute later! And the specific proof steps have been shown in front of them.

Now the demons are so abnormal!

How can we live at the same time as him!

Cheng Nuo did not go to see the group of students themselves that "terror like this" evaluation.

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

Tomorrow, there is a big thing waiting for him.

…………

The next day, in the morning.

Today is a very important day for many students in universities around the world.

Because at this time of year, the winners of the mathematical modeling contest for American college students will be published on the official website.

Certificates and medals will then be shipped from the headquarters of the Mathematical Association of America to universities around the world.

Early in the morning, Cheng Nuo was called to the office building of several institutes and sat in front of a computer with several leading teachers.

At 10:00 Kyoto time and 22:00 U.S. time, the official website of the US match announced the winners of the major awards.

This time, Tsinghua University of mathematics is naturally running for the o prize.

For them, an o prize is more important than ten f awards and M awards.

Tick, tick!

The clock keeps turning, and it is getting closer and closer to that time node.

Tick!

Ten o'clock sharp.

The head of the mathematics department glanced at Cheng Nuo behind him and took a deep breath. He opened the official website of American Games and opened the column of "prize list".

The order of awards is from big to small.

First there are twenty o awards, then f awards and M awards.

However, the internal ranking of the awards has no priority, and the list is arranged according to the English initials.

The head of the mathematics department looked at the first column of the o prize.

The prize winning group is from Harvard University in the United States, and the title of the paper is

The second column is from Oxford University in Yingguo.

The third column is from boffin University in ancient Germany.

…………

He scanned line by line, but never saw the familiar name of the school. I was about to sigh with disappointment, but my eyes suddenly stopped.

In column 18 of the o prize, he saw the familiar school and name.

Members of the winning group: Cheng Nuo, Anyang, Shi Qi

School: Tsinghua University
