Go home.

Continue to comb through the content of the research.

Wang Hao worked for another half an hour, feeling full of exhaustion, he simply stopped to rest.

Put on your shoes and go out.

Wander around the neighborhood and surroundings to relax and get to know the surroundings.

The environment near the community is very nice.

On the east side, there is a small park, around the small park is a hospital, and then turn back to a spacious commercial street.

Walking into the shopping street, there is a fast food restaurant around the corner.

Wang Hao touched his stomach and felt still a little hungry, so he simply went into the fast food restaurant and ordered a hamburger set meal to sit down to eat.

Fast food restaurants are doing a good business, and people come and go.

While I was concentrating on destroying food, I heard a hearty voice ask, "Handsome guy, is there anyone here?" ”

Wang Hao raised his head and found that it was a little familiar.

Door?

The skinny girl seems to be called 'Yoyo', and the chubby girl is called ...... What's going on?

I can't remember it for a while.

Li Qian quickly recognized Wang Hao, so she pulled Gu Youyou to sit down, "It's the door, just sit here!" ”

After she finished speaking, she asked symbolically, "Don't bother, right?" ”

“…… Never mind. ”

Wang Hao looked at the two girls carefully, thought about it for a long time, and couldn't remember what it was called, so he simply continued to destroy the food.

The two girls seemed to be interested in Wang Hao, and looked over from time to time after sitting down.

Li Qian couldn't help but ask, "I don't know what your name is?" ”

"Wang Hao."

Wang Hao said while eating.

"You rent a house by yourself, more than 2,000, you work, right?"

"Hmm."

"What kind of work?"

"Teacher."

Wang Hao nibbled off the last bite of the hamburger before finally raising his head, "Check the household registration?" ”

"No, no!"

"Haha~~"

Li Qian was a little embarrassed, "I just want to find out." ”

Suddenly, there was silence.

The two girls were not idle waiting for the meal, and took out their books to look at them intently.

Gu Youyou thought about a topic, pointed his forehead hard with the tip of his pen, and said to Li Qian full of worry, "Have you thought about this proof question?" ”

Li Qian turned her head and glanced at it, and said unconcernedly, "Give up." ”

"I knew it."

Gu Youyou covered his head helplessly.

Li Qian sighed, "I gave up a long time ago." Now I regret that I shouldn't have applied for the mathematics department when I took the college entrance examination; If you don't apply for the Department of Mathematics, you won't be able to study for a graduate degree in applied mathematics; If you don't study as a graduate student in applied mathematics, you won't encounter these complex problems. ”

Wang Hao was about to get up and leave, and immediately sat down in the seat after hearing this, "What are your math majors?" ”

"What's wrong?"

Two girls looked over.

Wang Hao was indeed a little surprised, in his memory, the number of female students at the same level of mathematics graduate students at Donggang University was pitiful, and it was impossible for them to be beautiful.

By the time she reached the Ph.D. level, the girls had disappeared.

He gave a thumbs up, "Awesome! Girls studying mathematics are rare. ”

"I'll see!"

Glancing at the problem on the table with curiosity, I immediately understood, "C[a,b] is an incomplete distance space in the sense of integral average convergence......"

"It's easy!"

Wang Hao said and took the pen and paper, and explained while analyzing, "This is a classic functional analysis problem, you must first set the value range of Xn(t) column, and the value of n is a natural number......

"Looking at these three columns, it's clear that {Xn} is included in C[a,b]."

"For the case where n is greater than m, d(Xn,Xm) is equal to ......"

"If {Xn} converges within this columnar region, it proves that there is an X(t)......"

“……”

“……”

"From this, it follows that C(a,b) is incomplete in the sense of integral average convergence."

After Wang Hao finished speaking, he looked at it carefully again, and found that there was indeed no problem, so he nodded with satisfaction.

Graduate-level math problems are indeed a piece of cake for him.

Gu Youyou and Li Qian were stunned on the spot.

They listened carefully along the train of thought, and they all felt that their scalps were numb, and they couldn't get around.

However, the other party solved it very simply, and there was no time to think, so simple that it was the same as copying the answer.

This is a graduate level topic in mathematics!

Li Qian looked up at Wang Hao and asked again, "What did you just say, what kind of work do you do?" ”

"Teacher?"

"Teacher?"

Wang Hao nodded lightly, pointed to the dining table and said, "It's your number, go get the meal." ”

"I'll go first."

With that, he walked out the door.

Li Qian was busy serving food, and when she came back, she saw Gu Youyou thinking, "What's wrong?" ”

"I'm thinking about what just happened."

"He's amazing!"

Li Qian couldn't help but admire, "I gave up on that question as soon as I saw it, and he actually wrote the answer directly." ”

"Don't you think it's weird?"

"What's strange?"

Gu Youyou nodded his fingers, as if he was incarnated as Sherlock Holmes, and analyzed seriously, "That question is difficult, the teacher has said it, just try to think about it, and you don't have to do it right." ”

"But when he looked at it, he knew the answer, as if he had done it."

"Even if you do, you have to think about it, right?"

"And he's a teacher. Even if you graduated with a master's degree, you still happen to be majoring in mathematics? Or do you happen to be doing this topic? ”

"Is there such a coincidence?"

Li Qian continued to nod her head, and also reacted, "You mean, he knew about our homework and conducted research in advance, just to find an opportunity to perform in front of us?" ”

"But what is the purpose of all this effort?"

The two looked at each other.

Li Qian said with a smile, "Otherwise, you'll be from it, right?" ”

Gu Youyou's face turned red, and he hurriedly said, "What nonsense, if you want to confess, just confess directly." Anyway, I'm sure I won't agree. ”

"Cut~~~"

"I don't know how to be blessed in the midst of happiness, if there is a boy chasing me with so much thought, I can get married on the spot!"

"Is it okay to live in a cave house?"

"!"

……

The next day was still 10 a.m. class.

Because I have the experience of one class, I don't need to prepare for it again.

Wang Hao came to school at nine o'clock and went directly to the classroom where the class was held, because it was three classes together, and the number of students was a little more than yesterday.

It's still that introduction, it's still that request.

Walk through the process with ease and remind all students that they must listen carefully in every lesson.

Subsequently, the course begins.

This time, a tutorial coin was used to facilitate the acquisition of inspiration for the research and development of the 'Fourier transform'.

Wang Hao felt that the course was progressing a little smoother, and he was still acquiring a steady stream of knowledge content in his head, but it was much worse than yesterday's situation.

Halfway through the lesson, he checked his progress and found that his inspiration had only increased by '31' points.

"This number is definitely not as good as yesterday."

"It's supposed to be a repetition question. There must be a limit to a single study, or in other words, many students have the same ideas, and they cannot bring new inspiration. ”

"But there are dozens of increases, and there are no less......"

The application of the 'Fourier transform' has a growing inspiration value, while the research of the 'analysis of partial differential equations' has a very poor inspiration value.

So far, it has only increased by '5' points.

"It's probably related to the difficulty and relevance of R&D."

"It's about the Fourier transform, the inspiration value grows relatively quickly, the analysis of partial differential equations is basic research, the difficulty rating is 'B', and the Fourier transform is just a method of partial differential solution."

Wang Hao thought carefully and understood.

He continued to engage in the lessons, interacting with the students and interspersing them with incidental knowledge to make the course informative and interesting.

Those students who listened carefully to the lecture felt that Wang Hao spoke very well, and it was not worse than the original 'Li Lao'.

Those students who don't attend classes......

Three were called up to stand for punishment, and one was half an hour late, and his name was simply noted for absenteeism.

……

Midday.

After Wang Hao had lunch, he returned to the office to work, and the application development and algorithm expansion related to the Fourier transform have been almost summarized.

He plans to split the content into three papers for publication.

Part of it is the application of Fourier transform, which is related to the content of partial differential equation solving, and mainly discusses and thinks.

The other two parts are Fourier transforms to assist in the construction of data models and apply them to the algorithm research of data analysis.

There is a lot of content in the latter part, and the total amount of more than 30 pages will be condensed, so it is not easy to submit and publish it in one go.

Because of this, it will be split into two parts.

In the afternoon, Wang Hao worked for more than three hours in a row, and then made a cup of coffee to take a break.

The main body of the paper has been almost written.

All that's left is to polish it, revise the format of the paper, and find an academic journal to submit it.

He also looked into the issue of submission.

The School of Science of Seohai University has a cooperative academic journal, which can be published directly after passing the editorial review of the university.

However, the academic journals we work with have very low ratings, barely reaching the 'recognized' level, and the academic field is not influential.

Influential magazines in China need to pay a high fee before they can be published.

Wang Hao decided to submit the article to a foreign journal - Computer Mathematics and Information Engineering.

Computer Mathematics and Information Engineering is a professional academic journal of mathematical computing, focusing on publishing research content in the fields of data architecture, algorithms, and information communication.

In the field of computer mathematics and algorithms, the influence of Computer Mathematics and Information Engineering ranks among the top 10 in the world.

The most important thing is that the published papers in Computer Mathematics and Information Engineering not only do not charge but also provide manuscript fees to the authors.

Although it is only a nominal 100 euros per article, it is better to have a manuscript fee than to have none.

"One hundred euros, three is three hundred euros!"

"Three hundred euros, three thousand dollars."

"If you publish three papers a week, you can earn 12,000 more a month, which is more than your salary...... This is also a good way to earn extra blocks! ”
