Dreaming can be a boss

Of course, just finding a proof method is not very powerful. After all, there are many ways to prove Cauchy’s median value theorem. At most, it is not very valuable to post an article in some ordinary journals.

However, Su Lu's special conversion method was the one he spent the longest time researching. He has blazed a new path in the past, and it can even supplement the current differential geometry.

Differential geometry is a branch of mathematics that uses differential calculus to study the graphic properties of curves and surfaces in three-dimensional Euclidean space. Su Lu's new method is enough to surprise the masters of mathematics.

In fact, he can't wait to enter the dream now and go to those masters for verification.

Put away the draft paper on which the proof process was written, put it in the bag, and at the same time say to Sister Shiyuan next to her, "Let's go, sister."

But when he turned his head, he saw Ning Shiyuan's pouting, unhappy appearance, and then he was startled suddenly, covering his mouth.

Just now because he solved a difficult problem, he was overjoyed by the joy brought by him. He went up and hugged his sister and kissed him, completely forgetting where he was.

Seeing Su Lu covering his mouth, Ning Shiyuan's cheeks were slightly rosy, and he gave him a hard look, then began to stuff his notebooks and books into his handbag, and then took Su Lu's hand out Walk.

It's not easy for the library to clean up this guy, let's go out and talk about it!

Su Lu was pulled, lost his footsteps, and those beside him looked at him with curiosity, teasing and envy. He was speechless, stared back, and said in his heart: A bunch of theatergoers, I have a daughter Friends envy you to death.

But he didn't realize that if he glared at someone, his powerful mental power would attack violently, and the average person would be startled. If he was a timid person, he might be terrified for several days.

When he stared at him, many people who looked over were startled, as if he had done something wrong, he was stared at by his father and dared not look up.

Fortunately, Su Lu didn't concentrate all his energy on staring at one person, but only attacked in a range, and the consequences were not too great, but those people didn't dare to look at Su Lu anymore, and they were secretly shocked: this person's eyes are too terrifying.

However, such a terrifying person was dragged out of the library by a woman, just like a mother dragging a child who made a mistake.

When he came outside, Ning Shiyuan said angrily: "Brother, have you become more courageous? So many people just... dare to mess around?"

Su Lu scratched his head, feeling like he wanted to say something to death: Do you mean that if there are few people, you can mess around?

But he still held back, not to mention that Ning Shiyuan still called him "brother", which meant that he was not particularly angry, but just because he was shy.

So he showed a smile, held his sister's two hands, and when his sister was about to throw away in anger, he explained with a smile: "Sister, listen to me. Guess what I just proved?"

Ning Shiyuan struggled to pull out her hand, and said angrily, "No guess, no guess! You! Little hooligan! Little villain!"

Su Lu saw that the misunderstanding had become bigger, so he quickly let go and said, "If this proof is published, at least it can be published in the journals of the second district! So I kissed my sister just now when I was happy."

Ning Shiyuan, who had let go, hid her hands behind her back and glared at Su Lu again, but when she heard "Journal of the Second District", she was stunned and asked, "Journal of the Second District? Which Journal of the Second District?"

Su Lu chuckled and said, "Which other periodicals are there in the second district? It's the periodicals in the first district and the second district."

Ning Shiyuan was stunned again, the embarrassment just now was completely forgotten.

Second district paper?

If she can write a thesis in District 211, she can directly graduate with a Ph.D. It might not be too difficult to even apply for a [-] university.

However, this also shows that it is difficult to write papers in the second district.

The doctoral students of the School of Finance are required to be officially published in domestic A-level or B-level journals, and the classification of papers is relative to international journals, sorted according to impact factors, and the method of Chinese Academy of Sciences is usually used in China to classify papers.

The second district is the paper with the impact factor in the top 6 to 20, whether it is SCI or SSCI, it is this classification.

The paper Su Lu researched was a mathematics paper, which was published in an SCI journal. If Ning Shiyuan wanted to graduate, it would naturally be a financial paper, which belonged to social science, and would be published in an SSCI journal.

But no matter what, a second district paper was enough to surprise her.

And my younger brother and boyfriend, who just entered the sophomore year, can publish a second district paper after casually studying for more than half a month?

What kind of magic realism is this?

"Really...really?" She asked in a daze.

Su Lu smiled and nodded. Seeing his sister like this, he wanted to laugh, not to mention how much he wanted to laugh. He held his sister's little hand again and said, "To celebrate, let me kiss you again."

After recovering from the surprise, upon hearing this sentence, Ning Shiyuan directly pulled her hands back, glared at Su Lu beautifully, and said angrily: "You think beautifully, little rascal, sister forgive you today, don't allow me next time." Recklessly."

"So it's okay if you don't mess around?" Su Lu asked with a smile.

"Go! Go away!" Ning Shiyuan snorted, pinched Su Lu's arm vigorously, after a while, lowered her head again, and said in a low voice: "If you want to kiss, you need to get my consent first."

Although the voice was very low, Su Lu could hear it clearly, and he was immediately overjoyed: "Then, does my sister agree now?"

"You're going to die!" Ning Shiyuan, who was ashamed again, raised her pink fist and lowered it towards Su Lu.

However, Su Lu had already run away with a smile on his face.

…………

Three days later, the Office of the Dean of the School of Mathematics.

"Eh? Why are you here, Su Lu? Do you have any questions?" Dean Jiang, who seemed to be about to leave with his bag, asked when he saw Su Lu knocking on the door and entering.

Su Lu showed a shy smile, and then said with some embarrassment: "I have completed the proof."

Dean Jiang shook his hand, put the bag back on the desk, and asked in disbelief, "What?"

"It is about the proof of Cauchy's median value theorem. I found a new method, and at the same time I promoted my proof idea, and proved both the Lagrange median value theorem and the integral median value theorem, and it was successful. "Su Lu had humility written all over his face.

Dean Jiang was stunned for a while, thanks to him being a math student, otherwise he might have to count how long it took Su Lu on his fingers.

But he still quickly recalled that less than a month had passed.

His expression was full of surprise, he stared at Su Lu's face, and finally couldn't help asking: "Are you so fast?"

Chapter 78 Suddenly thought of

Hearing this unexpected soul questioning, Su Lu scratched his head, and suddenly felt that this sentence was a bit familiar.

During the summer vacation, Professor Zhang seemed to ask him the same question...

Can you talk quickly about work and academic matters?

Men can't say fast, they have to say big... Cough cough.

But this sentence can only be slandered silently in my heart, but I can't say it to the old professors.

At this time, Dean Jiang, who had calmed down, recalled what Su Lu said just now, and then caught the key point, and was surprised again, and he asked hastily: "You mean, your way of thinking can be generalize to proofs of other theorems?"

Seeing the old man's excited appearance, Su Lu blushed for a while, he was really afraid that Dean Jiang's blood pressure would be high and he would faint.

He took out an A4 paper that he had printed out from his bag, handed it to Dean Jiang, and said with a smile, "Dean Jiang, don't get excited, this is my thesis, you can read it first."

Dean Jiang nodded, and he calmed down again. He really lost his composure just now, and he really had to read the paper first.

Mathematics is a rigorous science. Every step of the proof process cannot be wrong. As long as there is a mistake, it basically means that most or even all of the process will fall short.
