Dreaming can be a boss

The light on the stage dimmed, and the staff quickly ran up to the stage to transfer various props and pianos in the dark, but the audience below began to feel a little aftertaste, and then secretly regretted that such a performance would not be heard for a long time.

And Su Lu, who returned to the backstage, had time to shake hands with the conductor and express his gratitude for this cooperation. After all, the performance on the stage just now was for the people of the whole country, so there is no need to repeat the rules of the orchestra. released.

"Very good, I look forward to cooperating with you next time." The conductor and Su Lu shook hands and said with a smile.

"I'm looking forward to it too." Su Lu nodded slightly, then shook hands with each of the principals, and then quickly left the studio. It's only around [-]:[-], and there's enough time to catch up with the plane after [-]:[-]. .

…………

After Su Lu's performance ended, it quickly aroused heated discussions among many people. Unlike the previous performance at the Chopin Competition, which was only known to a few people, this time it was a program that the people of the whole country paid attention to. Su Lu's performance undoubtedly sparked There was a heated discussion, and almost an hour after Su Lu's performance ended, he quickly jumped to the forefront of the major search rankings.

Countless people came to Su Lu's Weibo account to leave a message under a recent blog post, asking him to go on a national tour as soon as possible, and people all over the country wanted to listen to his performance again.

However, Su Lu just replied: "This June, I have a surprise for you." Then there was no response.

As a result, others thought that Su Lu was really going to hold a concert, so from the first day of the Lunar New Year until June, there were departments in charge of external liaison in some cities who hoped that his concert would go to their city for the first stop. There are also some companies that specialize in contracting large-scale performances and activities, expressing their willingness to cooperate with Su Lu to promote him, and some performance venues in big cities hope that if he comes to perform in their cities, he must contract their venues, and the fee will be [-]% off All the way up to the fracture.

All in all, anyway, almost everyone began to wait for the day when Su Lu released the news of his planned tour.

However, only Su Lu knew what kind of surprise he was talking about in June.

288 chapters graduation thesis completed

This Spring Festival passed quickly, and many programs on the Spring Festival Gala made people enjoy talking about it, and Su Lu's performance was also edited into a single video and circulated on major video sites, including music player software. copyright, uploaded the version of the Yellow River Piano Concerto to their platform, and the number of plays on the first day exceeded one million.

However, none of this will affect Su Lu. After all, the copyright belongs to CCTV, and it is naturally impossible for CCTV to give him any money.

During the period, Ning Shiyuan and her parents spent a few days visiting relatives and paying New Year's greetings in the imperial capital, and then came to Xicheng County. It's really normal to see both parents with her boyfriend during the New Year.

In this way, the two families almost did not set a wedding date.

Soon, at the end of February, Su Lu and Ning Shiyuan returned to Shanghai, and there were still things to do.

…………

"Su Lu, you haven't told me what your topic is."

At the Shanghai University of Finance and Economics, Dean Jiang looked at Su Lu and asked helplessly. He suspected that Su Lu had forgotten to write his graduation thesis.

"Think about it, you have to write your thesis, and you have to find a journal to publish it and wait for the manuscript. This period of time is very long. Even if the college arranges for you and delays the defense time from April to June, you Not much time left."

Su Lu smiled and said, "I'm sorry, Dean Jiang, I actually started to prepare after I went back for the Chinese New Year, but I forgot to tell you."

Dean Jiang: "... I remember you were still performing at the Spring Festival Gala, you kid can do it, but you still have time to write a paper when you go to the Spring Festival Gala?"

"It didn't take much time to rehearse, and the rest of the time can be used for writing."

Dean Jiang waved his hand, too lazy to entangle with Su Lu on this: "Okay, okay, then can you tell me what your thesis is now?"

"That's the hail conjecture."

"Oh, hail conjecture, this is quite difficult, you wrote it..." Dean Jiang suddenly realized that the hail conjecture is not limited to the scope of "quite difficult".

"You want to solve the hail conjecture? How long will it take you?"

Su Lu stroked the palm of his hand, a shy smile appeared on his face, and then he said shyly, "Hurry up."

"..."

Dean Jiang stared blankly at Su Lu for a long time, took a deep breath, and said, "Can you show me?"

"Of course." Su Lu nodded: "If you don't tell me, I also want you to help me see if there is any mistake in my proof process."

Then he used the computer in the office to transfer his staged results to the computer, and then let Dean Jiang start to read it. At the same time, he began to explain some of Dean Jiang's problems.

"This is the induction method... How do you determine that the value of kn will definitely become a number that can become 2 to the m power after the next transformation?"

"Through formulas 3 and 5." Su Lu began to explain, and took a piece of waste paper beside him and started to calculate.

"In short, we can be sure that before x returns to the value of 1, it must pass through a certain number on the nth power of 2. As long as it reaches such a number, it will inevitably fall like a hailstone in the next countless formulas. To the bottom, which is 1, that is to say, we only need to prove that kn is 2 to the m power.”

"Then we can know for sure that kn must be an odd number, and 3 times kn plus 1 is 2 to the m power."

"How to prove that kn must be such an odd number, combined with formulas 3 and 5, to start proving..."

Su Lu began to calculate on the waste paper.

Dean Jiang watched, frowning involuntarily.

"This function...why is it so familiar? It seems to be a trend function? It's not right, have you transformed it?"

Although the trend function proposed by Su Lu was used to study finance, over time, more and more scholars have found that the trend function is not only useful in finance, but also in the study of other mathematical fields. Questions are also very useful. There have been related papers that have explained other uses of the trend function in detail. Therefore, Dean Jiang has also studied the trend function, and in any case it was created by his students. He studied it himself. Research can never be overstated.

Hearing Dean Jiang read it, Su Lu smiled and said: "Yes, the deformation process is another paper of mine, I have already written it, I will explain it to you now, and then I will explain it to you again How did it change shape?"

Not to mention how surprised Dean Jiang was, he could only nod in the end, and then concentrated on watching how Su Lu calculated for him, but then he witnessed with his own eyes how easily and simply Su Lu used this transformation The trend function of proves the hail conjecture, as if it is irresistible.

"...From this we can start the general induction. After that, I haven't finished it yet, but the most difficult part has been completed, but it is certain that there are no problems."

Dean Jiang looked at the last equation on the computer, a little dazed.

After all, for a person who has studied mathematics for a long time, seeing with his own eyes the final answer to a problem that has troubled everyone in the mathematics world for decades, is gradually revealed in the hands of his students. possible.

And Su Lu's explanation to him was also very detailed and thorough, so that he could understand it completely without any doubts. In fact, even if it was the proof in the paper, Su Lu also proved it very complete. There was nothing such as "well known", "obviously "Wait for the expression, this kind of proof process, Dean Jiang felt that even without Su Lu's explanation, he could understand everything after a few days of research.

But the most critical thing is the application of the transformed trend function in the full text.

"You..." The old dean looked at Su Lu, and finally showed a gratified smile on his face: "You are the best student I have ever accepted."

Su Lu grinned: "I thought you were going to say that I was the worst class of students you ever taught."

Dean Jiang laughed, "Isn't that what middle school teachers often say? University teachers probably wouldn't say that."

Su Lu smiled and didn't say much: "Let me show you my transformation of the trend function."

Dean Jiang nodded.

Then Su Lu opened another paper and explained it to Dean Jiang again.

"Trend theory?"

"Well, I summarized the trend function and incorporated it into an overall theoretical system." Su Lu nodded.

Dean Jiang was too lazy to be shocked anymore, he was afraid that his heart would not be able to hold it.

After reading the whole paper, Dean Jiang couldn't help sighing, and then said: "Your paper can be used as a graduation thesis."

Su Lu smiled lightly, "If the proof of the Hailstone Conjecture is used as my undergraduate thesis, it must be quite a credit to the school."
