I really don't want to lie down and win

Xu Mang was a little confused.

At any rate, he was an associate professor, but he couldn't do a doctoral-level topic in the first place. It seems that he didn't learn mathematics well...the business ability is not enough.

somewhat autistic,

For the first time, Xu Mang had doubts about his mathematics.

Logically speaking, if you glance at this kind of problem from the corner of your eye, you will know how to solve it. However, this is not the case, and even a second glance is not enough. Not only that...I still don't know the answer.

Xu Mang found a cafe on the campus of Tsinghua University. He thought that no one would come to this kind of place, but it was full of people.

After finally grabbing a seat, Xu Mang ordered a cappuccino, asked the waiter to borrow a black pen and some white paper, and began to solve this doctor-level super-difficult power series convergence problem.

counting, counting,

Xu Mang found out that it wasn't that he had a problem with his professional ability, but that this professor was a wolf!

good guy...

This is deliberately making things difficult for those PhD students!

No wonder it takes two days. It is estimated that half of the PhD candidates will be unlucky.

In fact, this is not a simple mathematical analysis problem. It integrates many problems into it. In the blink of an eye, it is just a power series convergence problem, but its real meaning is not this.

Just like Yang Xiaoman,

Looking at the back at first glance, it feels like a fairy descending to earth, but looking at her front, the fairy descending to earth is not in the right posture, and she fell flat.

It's not rough, it's almost the same.

interesting!

Very challenging!

Xu Mang was aroused by this problem for a long time to fight, and began to solve the problem on the draft paper. Since Xu Mang learned advanced mathematics, his thinking has changed. Even elementary school math problems, he is used to using micro Points to solve problems.

The temperature of the coffee was about the same as Master Lu's, so it was completely cold, but after such a long time, Xu Mang only managed half of it.

at this time,

A girl sitting next to him was staring at Xu Mang.

looks very ordinary,

Not very pretty, compared to Yang Xiaoman, this girl is a passerby.

"classmate?"

"Are you from the mathematics department?" the girl asked curiously.

"No."

Xu Mang shook his head, and said silently, "I'm from the Milky Way."

"..."

"I...uh...you are so funny." The girl was amused, and said with a smile: "A sophomore in the Department of Materials, my name is Zhang Ting."

"Oh..."

"My name is Xu Yang." Xu Mang reported the name of his future son. Xu Yang was taken from the surnames of Xu Mang and Yang Xiaoman. This was the name they gave their child on a whim one night. The boy's name is Xu Yang, and the girl's name is Xu Aiyang.

Xu Yang?

What a strange name!

"Your name is a bit strange." Zhang Ting said, "Both are surnames..."

Hearing Zhang Ting's words,

Xu Mang put down the black pen in his hand, and asked cutely for a year, "Is the name Xu Yang strange?"

"It's not very strange. I thought it was strange at first, but after a long time, I found that this name is quite good." Zhang Ting said with a smile: "Your father's surname is Xu, and your mother's surname is Yang?"

"..."

"Actually, my name is Xu..." Xu Mang was about to announce his name when he was interrupted.

"Junior Sister!"

"I didn't expect you to be here."

suddenly,

A rather handsome young man came, and after seeing Zhang Ting, his face was full of joy.

but,

When he saw Xu Mang, his face turned from sunny to cloudy.

"Who are you?" The handsome young man was full of hostility towards Xu Mang.

"..."

"Guess?" Xu Mang suddenly became mischievous, and said with a smile, "Guess?"

I...

After confirming with his eyes, he is not his competitor.

Tingting probably doesn't like this kind of psychosis.

"School girl."

"Recently, I discovered some flaws in Xu Mang and Xu Dashenguang's theory of self-torque...I want to discuss it with you alone." The young man said with an embarrassed expression, "How is it?"

Xu Mang: 囧
