From the second day, the number theory group began to study with Ye Fei and them.

Ye Fei will study whatever they study.

At eight o'clock in the morning and eight o'clock in the evening, Ye Fei and they studied for twelve hours a day, and they studied for twelve hours, and they had to review after returning in the evening.

The two of them have no opinion, anyway, they don't teach these people, and the teaching task is done by Ye Fei.

Ye Fei and Armatta stood in front of a whiteboard, Ye Fei wrote and drew on it, and the rest of them sat around with pens and notebooks, listening carefully to the research of the three of them.

There are a lot of things they don't understand, but they just need to write them down in a notebook and study them slowly.

Ye Feidao: "Establishing the connection between generalized Boolean functions and ideal groups of imaginary quadratic domains can obtain some new results on the non-existence of generalized Boolean functions." ”

Boolean functions play a fundamental role in complexity theory and chip design for digital computers.

It plays a key role in cryptography, especially in the design of symmetric key algorithms.

As he spoke, Ye Fei wrote down the formula on the whiteboard.

[Let q and n be positive integers......]

Han Dong sighed in his heart: "I didn't think it before, but now I realize that the gap between me and Ye Fei is so big." ”

"The gap between me and Amata is very big, not to mention that Ye Fei is stronger than Amata and the two."

"Hey......"

It is very painful to study more than a scumbag and a bully.

Take the strength of the other, and attack the shortcomings of yourself.

You will find that the other party is smarter than you even if they work harder than you.

Even if you're smarter, you'll work harder than you.

And the rest of the people's thoughts are that Ye Fei is awesome.

Although they couldn't understand it, they could also see that the research of Ye Fei and the three of them was mainly based on Ye Fei, supplemented by Amata.

You know, the two of them are very capable.

But even so, it is still dominated by Ye Fei.

This is enough to show that Ye Fei's ability is stronger.

And what they don't know is that Amata's two people think the same way as everyone else.

Before cooperating with Ye Fei, I didn't know how powerful Ye Fei was, but after cooperating with him, I didn't know how powerful Ye Fei was.

It seems that all his thoughts in academics, what he knows, Ye Fei knows.

What he didn't know, Ye Fei still knew.

That's pretty awesome.

They even had a worship for Ye Fei in their hearts.

Ye Fei was also very excited in his heart: "Working with Amata, plus so many people studying with me, my inspiration is increasing rapidly every moment. ”

"Brainstorming, inspiration multiplies."

Time has passed, and a week has passed, and the first problem of the Gaussian conjecture of the imaginary quadratic domain, the final determination of the imaginary quadratic domain of one class of numbers, has been studied 90%.

Ye Feixin said: "It's too fast, there are three or four days to prove the final determination of the imaginary quadratic domain of one of a class number." ”

At this time, it was noon, and Ye Fei had just finished lunch and walked out of the cafeteria.

"Professor Ye!" Suddenly, there was a cry behind him.

Ye Fei felt that the voice was familiar, and he turned to look.

I saw Fan Siyu walking briskly with a pair of slender long legs, her skin was brighter than snow, and her eyes were like a pool of clear water.

Dressed in white shorts with short sleeves, revealing a thin waist.

Her long hair, like splashed ink, reached her waist, falling behind her back, swaying from side to side with her movements.

Fan Siyu is not very old, about twenty-seven or eighteen years old.

Her good looks often attract the attention of many students.

Ye Fei's eyes lit up, it was the first time he saw Fan Siyu dressed like this, it was very eye-catching.

But he is by no means crooked, just an appreciation for beautiful women.

Ye Fei said with a smile: "Miss Fan! ”

Fan Siyu stood at a distance of one meter from Ye Fei and said with a smile: "Professor Ye, long time no see!" ”

"yes, long time no see." Ye Feidao.

The two hadn't seen each other for more than three months.

Ye Fei asked, "Miss Fan hasn't been at school recently?" ”

"Yes." Fan Siyu said: "Recently, the company has a situation, so I went back and dealt with it." ”

Ye Fei nodded.

Immediately, the two walked forward slowly side by side.

Fan Siyu said: "Congratulations to Professor Ye for his outstanding achievements at the International Conference of Young Mathematicians. ”

Ye Fei said with a smile: "What a brilliant achievement, it's just an academic report." ”

"Hey......" Fan Siyu looked sideways at Ye Fei and smiled: "As far as I know, this is not an ordinary academic report, I heard that one is the son of a Fields Medal winner, and the other is a student of a Fields Medal winner, and the two of them do the same academic report as you." ”

"But you beat them and won the first place."

"Later, these two people were dug up to Zhonghu University, is that so?"

Ye Fei said: "Yes, it is purely an accident that I can do an academic report on the same topic with them. ”

"There is no competition between us, to be precise, academic exchanges."

Fan Siyu said, "Professor Ye, is your work in the laser laboratory over?" ”

"It's over."

It's no secret that many people in the school know about it.

Fan Siyu asked, "Then Professor Ye, have you been busy lately?" ”

Ye Fei looked at her and said, "You still want me to go to your company as a consultant?" ”

"Yes." Fan Siyu said: "Professor Ye, if you have any conditions, as long as it is reasonable, the company will agree." ”

Ye Fei looked at the eager Fan Siyu and sighed in his heart.

He couldn't bear to make a girl wait so long.

But I'm really busy and don't have time to do research in the private sector.

If the research is important to the country, he will put aside his academic research and go to technical research.

But femtosecond laser technology, this is a technology that benefits the people.

At the national level, however, this technology is dispensable.

Fan Siyu said quickly: "Professor Ye, I have been inviting you for more than half a year, please give my company a chance." ”

"Not long ago, Zeiss increased the cryptographic fee for Xia Guo's femtosecond laser by 50%."

"We really, really need your research."

Fan Siyu's company is making medical equipment, and they invited Ye Feishi to develop femtosecond lasers.

The world's best femtosecond laser comes from Deutsche Zeiss, which pays billions of cryptographic fees to Zeiss every year.

For a long time, some medical device companies in Xia Guo have become agents of Zeiss, and they have cooperated very well.

But not long ago, ZEISS suddenly increased the password fee by 50%.

Moreover, only Xia Guo has increased by 50%, and the rest of the countries have not improved.

This made these medical device companies in Xia Guo very angry.

Only the Xia Kingdom has been promoted, and the rest of the countries have not been promoted, isn't this bullying!

Ye Fei said in surprise: "Really? ”

"Of course it's true." Fan Siyu said anxiously: "I can't deceive you in this kind of thing, if you don't believe it, you can find someone to inquire, almost all medical device companies know about it." ”

Ye Fei took a deep breath and said, "Okay, but not recently." ”

"Professor Ye......" Fan Siyu said impatiently.

Many people nearby saw a beautiful woman anxiously in front of Ye Fei, and they were very curious to stop and watch.

Ye Fei said: "Don't worry, a week later, I'll help your company in a week." ”

"But I have a precondition."

Fan Siyu breathed a sigh of relief, as long as Ye Fei helped.

Any of Ye Fei's conditions, as long as they are not excessive.

Ye Feidao: "I have only one condition, if I really help your company develop a femtosecond laser, your company will only grant Xia Guo Medical Devices a password fee that is higher than 10% of the cost of research and development." ”

"As for the password fee granted to foreign companies, I don't care, your company is arbitrary."

Ye Fei also inquired that medical equipment is a profiteering industry.

When a medical technology is developed, it is very normal for the password fee authorized to the medical device company to be three or five times the R&D fee.

Even some monopoly technologies, or unique technologies, where the password fee is ten or twenty times more common.

And the 10% password fee is a very low price.

Fan Siyu said: "I need to discuss this matter with the company, give me half a day, and I will give you news before six o'clock tonight." ”

Ye Fei said that the password fee to Xia Guo Medical Device Company was only 10% higher than the R&D fee.

She didn't know if the company would accept it.

After all, Xia is the world's largest consumer market.

With such a low crypto fee, the company will make a fifth less money.

"Good!"

After the two negotiated, Fan Siyu didn't chat with Ye Fei as usual, she left immediately after she said a word, and before she returned to her residence, she took out her mobile phone and contacted the chairman of the company.

Fan Siyu said: "Chairman, Ye Fei has promised to develop femtosecond lasers!" ”

"Good." The chairman said excitedly: "Daughter, I'll just say, as long as you tell Ye Fei about this, Ye Fei has a high probability of helping the company, you see what I said is right!" ”

Fan Siyu said solemnly: "Chairman, it's work time, and you and I are now in a relationship between superiors and subordinates, please call me Manager Fan." ”

"Okay, daughter, did Ye Fei put forward any conditions?"

Fan Siyu was helpless in her heart, and said: "He didn't put forward any conditions, but he wanted that after the femtosecond laser was developed, the password fee authorized to Xia Guo Medical Device Company should not be higher than 10% of the research and development fee." ”

“10%？” The chairman exclaimed: "How is this possible, even if I agree, the directors will not agree, this fee is too low, it is equivalent to giving technology to these medical device companies." ”

"But the chairman, Ye Fei only said that the password fee to Xia Guo Medical Device Company should not be higher than 10%."

"There is no limit to the cryptographic fees of foreign companies."

"If Ye Fei really develops a femtosecond laser, Xia has a large population, even if it is 10% of the password fee, the company will also make money, plus the foreign market, the money will still be very considerable."

"Of course I do." The chairman said: "But, who dislikes having more money, you say yes!" ”

"Chairman, don't you know how difficult it is to invite Ye Fei, I have been grinding hard for more than half a year before he finally let go."

"Ye Fei's request is like this, if you can't convince the directors, Ye Fei will definitely not agree to help the company."

"My words have been brought, you can watch it!"

"Good daughter." The chairman smiled and said, "You can talk to Ye Fei again." ”

"Chairman, Ye Fei's attitude is very resolute, I really don't have the confidence to convince him."

"You haven't been in contact with Ye Fei, you don't know Ye Fei, he is very principled."

"And, for helping the company, for him, it doesn't have to be done."

"And the company must win for Ye Fei."

"Ye Fei's request, we have to agree."

"Therefore, we can only convince the directors, but we can't convince Ye Fei."

"Okay!" The chairman said helplessly: "I can try." ”

"As soon as possible!" Fan Siyu said: "I promise to reply to Ye Fei before six o'clock tonight." ”

"Okay, I'll try to convince the directors in those six hours."
