Chapter 50 Organize data and collect clues

On the desk, Xu Chuan frowned as he stared at the numerous encrypted messages.

On the surface, these problems are indeed irregular. Even if various types of functions are arranged according to time, there will be no problem. The mathematical laws hidden behind them are like order in chaos, invisible. .

Of course, Xu Chuan didn't expect to find clues at a glance.

If it were really that easy, it wouldn't have been solved until 2017 in my previous life.

Although there is a lack of truly top mathematicians in China, and no one has won the Fields Medal yet, there is no shortage of world-class mathematicians.

Some people have won top mathematics awards such as the Wolf Prize in Mathematics and the Chen Shengshen Prize in Mathematics.

It's just that there are too many categories and knowledge contained in the subject of mathematics. However, the achievements of domestic mathematicians are not in functions. Most of the top mathematicians are famous for geometry and calculus.

"It's really troublesome to mix functions and base conversions, and you can't see anything at all."

"Separate the two first, and then see if you can find anything."

Staring at the math problems on the table, Xu Chuan muttered to himself, got up and found the staff standing guard outside the door. He asked for paper and pen, and began to separate the math problems on the card from the hexadecimal transcoding one by one. open.

The two are mixed together, and it is really impossible to analyze anything more.

When a mathematical problem is mixed with other problems, if you want to analyze the mathematical rules in the problem, the best way is to take it apart and restore it, so that the mathematical problem is exposed nakedly.

This was one of the methods he used in his previous life to prove the existence and quality gap of Yang-Mills theory.

The black pen in his hand sketched mathematical symbols one by one on the white manuscript paper. Xu Chuan separated the mathematical problems and base transcoding in these problems one by one.

This is not very difficult for him, but it is troublesome.

First, there are a lot of problems and the amount of work is quite huge.

Second, the difficulty of these problems is not low, and even he will need a certain amount of time to solve them.

He didn't have lunch or dinner. He huddled in a corner and kept breaking down groups of questions. By the time his stomach growled with hunger, it was completely dark outside.

After shaking his head and feeling a little painful from hunger, Xu Chuan stood up and moved his body. Outside the window, the campus of Riyue University was brightly lit.

"Let's go have a meal first."

After touching his belly, Xu Chuan packed up the manuscript papers on the table and put them in the drawer.

In six or seven hours in one afternoon, he probably solved about one-fifth of the total problems at hand, and the rest would probably take about two to three days.

On the one hand, the difficulty of these problems is indeed quite high, and sometimes he will encounter some mathematical problems that are not deeply involved in the field.

On the other hand, he still needs some time to sort out the core of the simplified method to solve the Dirichlet function.

This was the main reason why he was pulled over by Zhang Weiping this time.

Coming down from the sixth floor, Xu Chuan walked on the campus of Riyue University.

The learning atmosphere of top universities is still quite strong. Even at eight or nine o'clock in the evening, the library is still full of people, with students walking around from time to time. After finding a canteen that was still open and eating something, Xu Chuan returned to the information building.

At this point, there was no one in the mathematics office, and the empty room was a little quiet. He didn't stay long. After taking some drafts, he dragged his luggage to the ninth floor and found the room where he slept at night.

Instead of doing things in a large empty teaching room, it is better to work in your own room.

Although he enjoys living alone, the room is too big and makes people feel lonely.

9027, Xu Chuan looked at the card hanging on the door and opened the door with the access card.

The room was temporarily renovated, but the facilities inside were complete, including a bathroom and a bathing area. However, there was no TV on the wall, instead there was a computer.

Although the environment may not be as good as a hotel, Xu Chuan does not have any requirements for a place to live. A bed to sleep on, a bathroom and a place to bathe are enough.

After taking a comfortable bath, Xu Chuan dragged his chair to the table and began to sort out the core ideas for solving the Dirichlet function using the simplified method.

After you have completed the verification and solved several Dirichlet function problems using this method, it is easy to sort out the core ideas.

At least for him it is.

After pondering for a while and constructing his thoughts, Xu Chuan started writing.

[A simplified way to find the Dirichlet function! 】

The Dirichlet function is a function defined over the range of real numbers and has a discontinuous value range.

Its image takes the Y axis as the axis of symmetry and is an even function. It is discontinuous everywhere, has no limit everywhere, and cannot be Riemann integrated.

This is a measurable function that is discontinuous everywhere, has a period, and has no minimum positive period

When f(x)=xD(x), the Dirichlet function can be used to construct a single-point function. Therefore, the Dirichlet function can also be used to construct a multi-point function.

On this basis, the damped free vibration equation x=exp(-at)*A*cos(bt+phi)

‘mx˙˙+cx˙+kx=0’, therefore, the above equation can be further expressed as x˙˙+2ax+wx=0˙

To sum up, by bringing the variation of the damped free vibration equation into the equation A*cos(phi)-c/q=L, the Dirichlet function can be converted into the integral of the Dirichlet function.

Starting from the properties of the Dirichlet function, then bringing it into the damped free vibration equation, and then using the two major calculation formulas of calculating criticality and linearly independent special solution in the damped free vibration equation, Xu Chuan started writing very quickly.

Tonight's paper is not only for the mathematics experts in the Information Security Department to read, it is also the original paper that will be submitted to the journal later.

Of course, if he wants to submit a manuscript, the paper will definitely need to be refined again. What he is writing now is just the core idea of ​​solving the Dirichlet function by the simplified method.

When submitting your manuscript to a journal, you need to include more descriptions.

In one night, Xu Chuan had already written down the core idea of ​​solving the Dirichlet function using the simplified method. For a scientific researcher, this kind of efficiency is simply terrifying.

Normally, the emergence of any new mathematical method requires a period of polishing, which can range from a few days to a few months. Sometimes it may even take more than half a year to come out.

Being able to sort out my thoughts and write them down perfectly in one night is simply unbecoming of a human being.

Xu Chuan also found his terrifying work efficiency quite incredible, but after thinking about it, he thought it was normal.

The strong energy brought by a young body, the quick and flexible brain, the large amount of knowledge brought by rebirth, and the sensitivity to scientific research make this seemingly impossible thing possible.
