Chapter 249

Gu Lu's days became more leisurely.

Just finished the things that BAB guessed, according to the arrangement, Gu Lu planned to rest for a while.

According to the normal plan, BAB guessed that Gu Lu was expected to take about a year to complete it.

In that case, time is not so tight.

But there was an accident in the middle of Simon.

This caused Gu Lu to have to speed up the progress.

The work, which was expected to be completed in 12 months, was completed in a hurry in just five months.

The time has been shortened by half, which is a good thing, but Gu Lu has also paid a corresponding price.

Staying up late for a long time made Gu Lu's health worrying.

Even when writing his thesis in the last few days, Gu Lu was completely supported by a willpower.

At that time, Gu Lu felt that he could become an immortal at any time.

Scientists are a high-risk industry, and this is not just talk.

This led to the fact that when Gu Lu and Su Xi went out to eat with a sallow face a few days ago, Su Xi saw Gu Lu like this, and he couldn't even care about eating, so he took Gu Lu to a nearby hospital for a physical examination with a tough attitude.

Fortunately, the physical examination report showed that there was nothing wrong with Gu Lu's body, but it was just too weak.

The doctor in the white coat glanced at Gu Lu and Su Xi next to him teasingly, prescribed a lot of drugs to nourish yang and kidneys, and then handed the prescription to Gu Lu, "Young man, be modest!"

Gu Lu: "???"

Su Xi lowered his head with a blushing face.

"Gu Lu, can you stop working so hard in the future! Fortunately, there is nothing to do this time, if it ......" In the underground parking lot of the hospital, Su Xi, who was sitting in the driver's seat, turned his head and said to Gu Lu while starting the car.

"It's okay, I'm still young and can handle it. Gu Lu waved his hand and smiled indifferently, "Besides, isn't it okay this time." ”

"And what about next time?"

"Next time. ”

"You ......"

"Don't worry, I'll be fine. It's just staying up for a few days and nights, and it's like a common thing for us scientific researchers. Gu Lu comforted Su Xi.

Su Xi raised his head and stared at Gu Lu tightly, "Teacher Gu, how about you resign and come to my company?"

"Ahem. Gu Lu glanced at Su Xi up and down, "Your ...... company?"

"That's right!" Su Xi raised his snow-white neck and looked arrogant, "Didn't I mention it before, I was the regional manager of Yanjing in one of our family's companies, and now, that company is all under my control!"

Gu Lu gave a thumbs up in admiration, "Amazing!"

"Then Teacher Gu, how about you resign and come over to help me. With your talent, even if you are anywhere, you can mix it up. Su Xi looked at Gu Lu with expectant eyes.

"So, what are you going to give me the position?" Gu Lu asked jokingly.

"My personal secretary, how's it going!" Su Xi replied without thinking, with a smile on the corner of his mouth.

Ahem......

How's that? Not so much, of course!

Gu Lu's expression was a little painful, "Forget it, I'll continue to be my teacher." ”

"Mr. Gu, I was joking just now! The position of the director of the technical department of our company has been vacant for a long time, Mr. Gu, how did you do in the past?"

Gu Lu smiled bitterly and shook his head, "I wasn't joking just now. Su Xi, I appreciate your kindness, but I still think that the profession of teacher is more suitable for me. ”

"Don't you really think about it?"

"No need. Maybe I'll change my mind later, but not now. Gu Lu declined Su Xi's kindness.

Gu Lu raised his wrist and looked at the time on his watch, "It's faster, let's find a place to have lunch first." This matter will be discussed later. ”

"Hmm. Su Xi lowered his head with a gloomy expression.

…………

It's still summer vacation time.

However, the number of people on the campus of Yan University is not much smaller than usual.

Including the army of graduate school entrance examinations, many Yan students chose to stay in school this summer.

In the library, in a window position, Bi Qi and Ma Zhengxuan sat side by side, holding a book and nibbling on it.

The book in Bizzie's hand is "Riemann-Finsler Geometry Foundations".

The book in Ma Zhengxuan's hand is "Calabi-Qiu Manifolds and Related Geometry".

These two books are only needed by graduate students who choose the direction of geometry.

And now, Bi Qi and the others are gnawing like crazy, and they are happy to do it.

Bi Qi and Ma Zhengxuan, like sponges, are frantically absorbing knowledge.

Suddenly, Bi Qi stabbed Ma Zhengxuan in the shoulder, pushed the book "Riemann-Finsler Geometry Foundation" in front of Ma Zhengxuan, pointed to one of the passages in the textbook, lowered his voice and said, "Zhengxuan, I understand this part this way, can you listen to it." ”

In order to maximize efficiency, Bi Qi and Ma Zhengxuan decided to read the same batch of books at the same time for a period of time, so that their ideas about the content of the books could be verified by each other, which greatly saved time.

Bi Qi had read the book "Riemann-Finsler Geometry Foundation" a few days ago, and Ma Zhengxuan had already read it.

Hearing Bi Qi's words, Ma Zhengxuan took his eyes off the book, nodded and spoke, "You say." ”

"This part is mainly about the relationship between the harmonic mapping of the Finsler manifold and the Finsler metric of the local projective flatness and the non-local projective flatness, and I think we should start with the distance between the two points of the Finsler manifold. Bi Qi said slowly.

Ma Zhengxuan nodded and continued, "Yes, as mentioned later, this distance is defined as the lower bound of the arc length of the curve connecting these two points. With respect to this distance, the Finsler manifold is a metric space, and the metric topology is consistent with the original differential manifold topology. In this way, many of the properties of the Riemann manifold as a metric space can be generalized to the Finsler space. ”

"Below, it's supposed to be ......"

Bi Qi and Ma Zhengxuan verified their thoughts with each other.

Sitting opposite, a boy wearing glasses and a plaid shirt naturally took the content of Bi Qi and Ma Zhengxuan's whispered discussion into his ears.

Then, the boy's gaze scanned back and forth between Bi Qi and Ma Zhengxuan in disbelief.

As soon as Bi Qi looked up, he noticed the gaze of the boy opposite, "Classmate, I'm sorry, didn't we talk too loudly and disturbed you." ”

"No, no, no, no, no. The boy waved his hand and asked, "You're math students?"

Bi Qi nodded, "That's right!"

The boy's face was overjoyed, and he said to Bi Qi, "My name is Zheng Jie, and I am a junior in the School of Computer Science. Our team is preparing for the upcoming National Robotics Competition, and there is a technical problem that requires some professional mathematical knowledge, but there is no mathematics department in our group. ”

"Two seniors, if you don't mind, can you go over and help us?" The boy looked at Bi Qi and the two with fiery eyes.

Senior?!

Bi Qi and Ma Zhengxuan glanced at each other with a wry smile.

Obviously, this male student of the Institute of Planning regarded them as graduate students in the Department of Mathematics.
