At noon, Zhang Weiping called and asked him to prepare for the afternoon class.

Xu Chuan packed up the information, sorted out his thoughts, and came to the math room in advance, and found that Zhang Weiping was already waiting for him here.

"Don't be nervous, don't be afraid, just think of it as your usual communication with your classmates and teammates."

Zhang Weiping smiled and comforted Xu Chuan, don't have too much pressure in his heart.

In fact, this can be regarded as a platform for Xu Chuan to let these mathematics professors in the mathematics room get acquainted with him, so that he can find some mathematics professors to ask for advice when he encounters problems in his studies in the future.

As for the questions and explanations, the core manuscript provided by Xu Chuan has been clearly described.

After all, this is not a very cutting-edge and complicated thing, and most math professors can understand it smoothly after getting the core manuscript.

Xu Chuan nodded and responded, if this is put on an ordinary student, even a doctoral student will be nervous.

After all, the mathematicians involved in the decipherment of encrypted messages are all top mathematics professors in China, and it is indeed not easy for a senior high school student to tell these professors who can be their own teachers about their knowledge.

But for him, it's nothing at all.

Before his rebirth, the physics and mathematics conferences he held were among the top in the world, and in comparison, today's meeting is really average.

However, he attaches great importance to it, because this is a good opportunity to solve the information war.

......

At half past one in the afternoon, in the mathematics room, there was no curtain or conference room, and a dozen mathematics professors chatted around a makeshift group table, just like the daily gathering and gossip chatting of housewives in the countryside in the evening.

"Ahem, okay, everyone is here, then let's start."

Zhang Weiping cleared his throat, coughed and continued: "Everyone is an old acquaintance, so I won't introduce much, but let's pay a little attention later, don't scare our classmates Xu Chuan, after all, they are only in their third year of high school." ”

Hearing this, the mathematics professors sitting around became lively.

"Lao Zhang, look at what you said, it's too late to love, how can you be scared."

"Senior year of high school, I would only play cards in the dormitory at that time."

"Xu Chuan, are you interested in studying at Shuimu University, you can mention the conditions, our Shuimu University is the first school in China."

Professor Wang Yuan of Mizuki University looked at Xu Chuan with a smile and invited.

"Heh, you old thing, in terms of mathematics, your water and wood are not as big as our P, if you want to come, you will also come to our P, Xu Chuan, come to P, I will take you personally!"

Academician Zhou Jianlin of the University of Mathematics frowned, and immediately retorted.

"Okay, what's there to be noisy about, today's topic is not to rob people! Don't listen to them, Xu Chuan, the mathematics department of Dongshan University is also very strong. ”

Professor Wei Anran of Dongshan College approved the first two and then joined the industry of grabbing people.

"Ahem, a bunch of old things, let you don't scare people, you're getting hard."

Zhang Weiping glanced at the mathematics professor sitting around, rolled his eyes, and he knew that this was the result.

However, after being interrupted like this, the atmosphere in the math room was also a lot more lively.

After rectifying the atmosphere in the math room, Zhang Weiping looked at Xu Chuan and said:

"Okay, let's start here now, Xu Chuan, don't be nervous, just be Lala's homework, after all, this group of old... What kind of personality you just saw. ”

"In this way, you first briefly describe the core idea of the simplified method you developed to solve the Dirichlet function, and then other people have questions to ask, if you have an answer, just reply, it doesn't matter if you can't answer, don't care."

Xu Chuan nodded, sorted out his thoughts, and explained the process of getting inspiration from "Advances in Physics" and then studying the damped free vibration equation and Dirichlet function.

He didn't focus on the core proof process, this thing is in the manuscript he listed two days ago, which everyone must have read and mastered.

“..... This is the whole process of simplifying the Dirichlet function. ”

After confirming that nothing was missing, Xu Chuan wrapped up and ended his presentation, waiting for the group of bigwigs sitting around to ask questions.

"I didn't expect Xu Chuan's achievements in physics to be so high."

"All-round talent in mathematics and physics, it's more suitable for us P University."

“.....”

Seeing that this group of people was coming again, Zhang Weiping directly interrupted: "Okay, if you have any questions, ask quickly, don't waste time, after solving this problem, he still has to participate in the national training." ”

was corrected again by Zhang Weiping, and everyone shifted the topic to mathematical problems.

However, for this group of bigwigs sitting here, it is not a problem to understand the core of the simplified method to solve the Dirichlet function, only the mathematicians involved in modeling have asked two questions.

"Xu Chuan, I would like to ask, according to your core, if you use the simplified method to solve the Dirichlet function modeling, from the transformation of the Dirichlet function to the integral, and then to the solution, there are a total of thirteen different steps and solutions in these two steps, right?"

Xu Chuan nodded, these were the things he had clearly written in the previous core document.

"Can you optimize it a little more? What I mean by this is that you can sort the solutions in a sequence according to the size of the corresponding solution range. ”

The math expert in modeling asked, "Because for a mathematical model, if you need to repeat the operation and choose it multiple times, it adds a lot of computing power." ”

"Therefore, it is better to put the core solutions with a wide range of adaptation to the first group, which can reduce the demand for computing power in the digital model."

Xu Chuan nodded and said, "This is no problem, I can go back and tidy it up." ”

"Then I'm bothering you."

.......

After a brief meeting and dealing with some problems in the establishment of digital models, Xu Chuan grabbed Zhang Weiping.

"Teacher Zhang, wait a minute."

As he spoke, he took out a stack of manuscript papers from the bag he had brought with him and handed it over.

"These are some of the solutions I've been working on in the past two days to solve those math problems, and I can't figure out some of them, can you help me look at them?"

He burned all the detailed manuscript papers, which he had written fresh last night.

It is a preliminary collation of the laws behind these cryptographic cores, providing only two or three ideas and some problem-solving data that is relatively in line with his current knowledge.

In order to disguise it, he also listed some data that could not be counted.

But that should be enough inspiration for the mathematicians in the Information Security Division.

"yes, okay."

Zhang Weiping took the manuscript paper and flipped through it, ready to point out this mathematical genius.

"It's normal that you can't solve this problem, because this is the direction of the PhD graduate's topic, and this function needs to use the Riemann lemma to integrate both sides at the same time, and then turn it to Lopida's rule......"

"Huh? Did you split those cryptographic functions? Interesting, strip the base system from the math problem, and then do the problem ......"

"The idea ......."

The manuscript paper was in sight, and Zhang Weiping became more and more surprised as he browsed the information, from the beginning, he could still answer the questions left by Xu Chuan, and point out his ideas, gradually, his whole person fell into contemplation, and his brows were unconsciously locked.

A way to find the mathematical laws behind the encrypted information sprouted in his mind.

Looking at Zhang Weiping, who was deep in thought, a smile appeared in the corner of Xu Chuan's eyes.

He knew that on his manuscript paper, Zhang Weiping had found the path to the answer.
