After returning from studying in the United States, Xu Shengzhou packed up and prepared to return to Jinling.

After collecting information, reading literature, and having heated discussions with people studying in the United States in the early stage, he has basically passed the stage of being "brought in by a master". The way forward will basically depend on "cultivation by oneself."

It's just like a college student who has just stepped out of school and entered the society. At this time, his parents are old and his teachers are far away. There is still a long way to go for the rest of his life, but in the end he has to go on by himself.

Xu Shengzhou asked for leave from Mr. Cheng, but the old man accepted it and only told Xu Shengzhou two words:

"You have just graduated from your master's degree and your Ph.D. has not yet started. In theory, you don't need to ask for leave. During this time, you can make friends if you want, get married if you want, and go wherever you want to play. You should also relax while studying.

Have moderation, but pay attention to safety!"

"School starts next semester, remember to report to school on time!"

Not like Dean Zhang Anping, who is a mother-in-law. When he heard that he was going south, he just called him into the office and chatted for more than an hour. He talked about how to be a man and not forgetting his roots, and how much he has been owed to his alma mater, and to the development difficulties of the School of Science and Technology in recent years;

He recited "One inch of time, one inch of gold" and "I advise you to cherish your youth", and then lamented that Feng Tang is old and his time is fleeting. Xu Shengzhou looked at Dean Zhang with a sullen face and tried to summarize his meaning: "Do you want to

Shall I finish the paper on Hodge's conjecture quickly?"

Zhang Anping suddenly looked like he had got the core idea: "That's right! Work hard, just like when you were studying for graduate school, and try to complete the thesis during your Ph.D. study!"

Xu Shengzhou's eyes widened: "Impossible! It will take at least two or three years to complete that paper——"

"That's why I ask you to work hard!" Zhang Anping said earnestly.

Xu Shengzhou shook his head: "Then I'd better think about how to publish another 'Big Four' article!"

Just before, he discovered that there is some profound connection between the stability of vector bundles and Frobenius homomorphisms. He has already written the beginning of the paper and will see if he can vote for the "Big Four". If he doesn't win,

, then go to the system to redeem one. Anyway, an intermediate academic paper only costs 100,000 points, so it is still affordable. In any case, it is important to graduate as soon as possible. Traveling back and forth between the north and the south like now is not easy.

It’s like a long-distance relationship, it’s so boring!

Zhang Anping obviously didn't expect Xu Shengzhou to have this skill. He was stunned for a moment and then said: "Then would you consider doing a postdoc in our mathematics department for a few more years?"

"..."

Xu Shengzhou is like an older single who was forced to go on a blind date during the Chinese New Year. He just said "I need to think about it again" and ran away.

Returning to the office handed over to him by Mr. Cheng, he quickly packed his things and prepared to evacuate. Suddenly there was a knock on the door. Being on his own territory, Xu Shengzhou was still a little confident. He imitated Heng Ping and said calmly: "Please come in!"

"Hello, senior brother!"

The other party's delicate and fair appearance was very recognizable, and Xu Shengzhou immediately remembered who he was: Lu Jiayang, a junior fellow in the School of Planning and Design. He had met him by chance at the Dao Dao Cafe in the east gate of the Normal University a few months ago, and at that time he gave me

He asked three questions. This must be a handover, right? Xu Shengzhou said with a smile: "We haven't seen each other for several months, but you are still so radiant. It seems that mathematics has not troubled you."

Lu Jiayang sighed and shook his head: "You don't have to worry about mathematics at all. The three questions that my senior gave me made me lose my hair! I used to only know that my senior is very good at mathematics. After learning algebraic geometry, I realized how good my senior is!"

”

Xu Shengzhou smiled and said: "There are talented people in the School of Planning and Design, each leading the way for three to five years. Maybe you will be the next person considered great by the juniors! How are you? How have you been reading the books in the past few months? I made the topic

How many courses?"

Lu Jiayang felt a little ashamed: "Algebraic geometry is really difficult. I first found some textbooks in the library and looked through them, but they made me confused. I had no choice but to go online and find some online course resources, and asked someone from Yanda University

A well-known professor tutored me for a few weeks before I barely got started. It’s really admirable to think that my senior brother could write such an excellent paper by himself by just reading a few books!"

Invite a well-known professor from Yanda!

How many weeks have you been tutoring?!

Lemon Spirit Xu Shengzhou expressed that he did not want to talk to such a big dog owner.

Pseudo·Mathematics Lover·True·Inhumanity·Lu Jiayang continued: "I followed my senior brother as an example and studied algebraic geometry seriously for several months, and finally saw its profoundness and vastness. The three principles given to me by my senior brother

I have only solved the first two questions, and I have just started on the third question, and I just barely have an idea. I heard that my senior brother will leave Beijing to go south in the near future, and I want to report the progress to you first."

Xu Shengzhou said: "Can I see the two questions you made?"

Lu Jiayang quickly took out his exercise paper from his schoolbag and handed it to Xu Shengzhou respectfully: "I originally wanted to invite senior brother to come over, but I was just afraid of wasting his precious time."

After Xu Shengzhou took the exercise paper, he quickly opened it. This was originally the question he asked. The content was clear at a glance. You didn't even need to use your "junior extraordinary academic vision" to see whether it was correct. In just ten seconds,

He finished flipping through the six or seven pages, then nodded and said approvingly: "Very good! As a sophomore majoring in computer science, I can solve two problems in less than half a year just by studying algebraic geometry in my spare time.

, this is already commendable! Not to mention you, even if a junior mathematics student has completed the algebraic geometry course, it will still take a lot of effort to solve the second question!"

Lu Jiayang looked at him expectantly: "Senior brother, do you think I am suitable for studying mathematics?"

Xu Shengzhou did not answer directly, but asked again: "Can you briefly explain the idea of ​​​​the third question?"

"Okay." Lu Jiayang took out a few more pages of A4 paper from his schoolbag and began to explain, "My idea is to use three-dimensional loop coverage and ternary coding to study the problem of the maximum number of cusps on the specified surface. First...

..." He kept talking for four or five minutes before stopping, waiting for Xu Shengzhou's final verdict.

Xu Shengzhou thought for a moment and then said slowly: "You should have no problem learning mathematics. With your hard work and talent, you will have no problem getting a doctorate. As for how great achievements you can achieve in the future, I can't say for sure. After all, I can't do it now."

Still a graduate student."

Lu Jiayang looked pleading: "Senior brother, can you help me talk to Dean Zhang of the School of Mathematical Sciences?"

Xu Shengzhou scratched his head: "It's okay for me to explain it to you, but shouldn't the key be that you seek your parents' opinions first?"

"I've already done it with my parents! This is the opinion letter issued by them." Lu Jiayang actually took out the opinion letter signed and fingerprinted, but it was unclear whether it was true or not. Then he took out his mobile phone again,

Clicking on a recording, there was a middle-aged man's calm voice, with a hint of helplessness: "I am the father of classmate Lu Jiayang. My name is Lu Tianjian. I respect and agree with Lu Jiayang's application for changing majors..."

I don’t know how this kid tortured his father!

Xu Shengzhou thought that he was about to go south, so he might as well be a good person and go to the end and send the Buddha to the west, so he just took care of the matter. So he stood up and said, "In that case, I will take you to see Dean Zhang now.

.I am only responsible for being a matchmaker and helping to introduce you. The specific procedures are still handled by you and the Institute of Engineering and Mathematical Sciences."

Lu Jiayang was overjoyed: "Thank you, senior brother! Thank you, senior brother!!"

Xu Shengzhou said: "You don't need to thank me, as long as you don't complain about me in the future. Also, I just looked at your answer and the ideas of your statement. Generally speaking, it is pretty good, but it can be seen that the foundation is still a bit weak. This

This is also a common problem among self-learners. If you want to transfer to a mathematics school, I suggest you start learning from your sophomore year to lay a solid foundation, which will be good for your future."

Lu Jiayang nodded repeatedly: "Okay, I will listen to my senior brother!"

Zhang Anping was still in the office. When he heard that Xu Shengzhou was going to introduce a student from the School of Engineering to transfer his major to the School of Mathematics, he immediately stood up excitedly, looked at Lu Jiayang several times, and then asked Xu Shengzhou in surprise: "Your junior brother?"
p>

"Well, yes."

"Have you tested him? Do you think he is suitable for studying mathematics?"

"Ah... yes, I think he is quite talented in mathematics."

Zhang Anping kept tapping his palms excitedly: "You think he has talent in mathematics, so why don't you transfer to our School of Mathematics?! What future can he have in the School of Engineering? You did well! You did it right! You can change your major.

Don't worry, the hospital will take care of it for him. If there is any problem with Dean Chao, I will go and talk to her!!"
