Chapter 354: O award

Chapter 354
Should count Li Jiani: "Speaking of that, there is really a problem, and I need your help from a teaching assistant!"
Classmate Li Jiani typed in the WeChat group. . Fastest update
She was not joking, but really had a problem to ask others to solve.
That was a homework problem left by their teacher of real variable and functional analysis last week.
She first thought about it alone with a pen for half an hour, but didn't figure it out.
After I asked my roommate later, I also found that every one would.
There is no way, Li Jiani can only ask the big scholars in the class, but the result is...neither will they!
This makes Li Jiani very uncomfortable!
Li Jiani was not familiar with the senior elder sister.
Besides, since the mathematics elders in my class have said that they have not solved it, it is difficult to say that they can give the answer even if I find a senior elder sister casually.
It just so happened that Cheng Nuo said so in the group chat, and Li Jiani thought of this.
One is to help myself solve math problems, and the other is to test whether my young teaching assistant is really as young and talented as the rumor has it!
"Send the question, I'll help you see it." Cheng Nuo didn't say anything.
If he said that he would be able to solve it 100%, then classmate Li Jiani directly flicked his face with Goldbach's guess, what would he do?
Let's wait for the topic to come out!
"The assistant teacher, wait for a while, I'll take a picture of the subject and send it to you." Li Jiani replied.
In a few seconds, Li Jiani posted a picture in the group chat.
Cheng Nuo clicked on slightly anxiously, and after a second, he breathed out lightly.
"How is it, can you solve it?" Classmate Li Jiani asked uncertainly.
"Wait for me for a minute."
After Cheng Nuo sent this passage, he turned off the phone and put it on the table.
Then, I opened the notebook on the desk, randomly tore off a piece of paper as a draft paper, picked up the pen, and wrote the formula on the paper like a hand.
The topic, Cheng Nuo has already read, is a very regular topic.
Of course, this routine is compared with Riemann’s conjecture, the four-color theorem, and Goldbach’s conjecture.
Cheng Nuo was really worried that Li Jiani, a little girl, would come up with a world problem and prevent him from getting off stage in front of more than 100 people.
Fortunately, Li Jiani should be sincerely asking for advice.
[Please prove that if (x, t) is a linear topological space of the second order, (y, -) is a linear quasi-norm 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 question is there, but it is only for ordinary outstanding students, and for Cheng Nuo, ha ha...
It can only be said that it is not even an appetizer.
He has long lost interest in such low-level interesting topics, if it weren't for pretending...
Wipe, say you missed it.
If it weren't for answering questions, you thought Cheng Nuo would solve this problem.
The pen tip is like a snake, swimming quickly on the paper.
After all, it took a minute to complete. If there are too many formulas to finish, then it will be really embarrassing.
In the group, after Cheng Nuo sent the "Wait for me a minute" message, the group also began to discuss.
Should count Wu Yong: "One minute? The teaching assistant will not go to the calculation tool, right?"
Li Yunteng: "Just take paper and pen. It took so much time. I think 80% of them went to the bathroom."
Should count Li Jiani: "I don't know such a difficult subject, can the teaching assistant handle it?"
Should count Lu Qiu: "It should be possible. I asked a graduate student about this topic at noon. He just replied to a message with a bit of clues, and it is estimated that he will be able to solve it tomorrow. If Assistant Cheng comes, it should be done in an hour! "
One minute will pass quickly.
In the group, Cheng Nuo first sent a message: "It's done!"
Get it? What's done? !
Seeing the three words, everyone in the group was dumbfounded for a while.
However, when I saw the picture posted after Cheng Nuo's text, all of them were horrified, and their brains suddenly became clear.
No way, it's only a minute? ! !
They all thought of the possibility, their fingers trembling, and hesitantly clicked on the picture.
What catches the eye is the word "proof" written in black carbon pen.
Below is a series of formula combinations.
That is the specific proof step.
[Since Λx∈x, the set {tjx; j∈j} is a bounded set in (y, -), so Λx>0, there is ns<0, sometimes there is...]
Line by line, step by step.
Cheng Nuo wrote the problem-solving ideas very clearly. Even their group of Tsinghua undergraduates can fully understand Cheng Nuo's proof ideas after reading one side.
At the same time, I also know that Cheng Nuo proved the correctness of the process.
One minute, it was only one minute after Li Jiani sent him the question! The specific proof steps have been shown before them.
Now the evildoers are so perverted!
How can we live in the same era as him!
Cheng Nuo didn't see the "horrible" evaluation of the students in the group.
After playing a few games, Cheng Nuo climbed into bed to sleep.
Tomorrow, there is something not big or small waiting for him.
…………
The next day, in the morning.
For many students in major universities around the world, today is a very important day.
Because of this time of year, the winners of the American College Student Mathematical Modeling Contest will be announced on the official website.
Subsequently, certificates and medals will be shipped from the headquarters of the American Mathematical Society to universities around the world.
Early in the morning, Cheng Nuo was called to the office building of the academy and sat in front of a computer with a few teachers who looked like leaders.
At 10:00 in Kyoto time and 22:00 in U.S. time, the official website of Meisai announced the winners of the major awards.
This time, Tsinghua University of Mathematics is naturally rushing for the o award.
To them, an o award is more important than ten f awards and m awards.
Tick, tick!
The hour hand keeps turning, and the distance to that time node is getting closer.
Tick!
Ten o'clock.
The director of the Department of Mathematics glanced at Cheng Nuo behind him, took a deep breath, and opened the official website of Meisai, and opened the "Winner List" column.
The order of the awards is from largest to smallest.
First there are twenty o awards, then f and m awards.
The internal rankings of the various awards are in no order, and the list is arranged according to the English initials.
The director of the Department of Mathematics looks at the first column of the o award~EbookFREE.me~ The winning team is from Harvard University in the United States.
The second column is from Oxford University in Yingguo.
The third column is from Bofei University in Germany.
…………
He scanned line by line, but he never saw the familiar school name. He was about to sigh in disappointment, but his eyes froze.
o In the eighteenth column of the award, he saw a familiar school and name.
