"Let's try to find a place to sit down first, if you really don't have a place, you can wait for the next opportunity to sign up, and if you want to take pictures and sign autographs, come to me after the open class is over."

Xu Yun looked a little surprised, he didn't expect that his first public class would attract so many students to sign up.

Stand on the podium to calm the crowd and maintain order, and then insert the courseware disk into the multimedia.

Fortunately, his prestige in the hearts of his classmates was relatively high, and as soon as his voice fell, the originally noisy classroom immediately returned to quiet.

But no one chose to leave, even if they stood for two hours, they had to finish the lecture.

Seeing that his classmates insisted, he didn't want to say anything, so he had to let them listen to the lecture like this.

Seeing that the official class time was about to arrive, several figures appeared at the door of the classroom again.

Qin Xiangxin, Dean of the Department of Mathematics, led the team and led two professors, Tang Yanshan and He Antai.

"It's pretty lively."

"Your public classes are the most popular among students right now." Qin Xiangxin stepped in first, glanced over at the attendance rate in the classroom, and smiled at Xu Yun and proposed, "How do you feel, do you plan to hold more events in the department every week?" ”

"This ......"

Xu Yun was a little speechless when he heard this, and did not give a clear response.

Today's open textbook is the dean's proposal, and if I really promise to come every week, I'm afraid it will be no different from the lecturer.

As a student who is about to graduate from undergraduate, you still have to aim for your studies.

Qin Xiangxin obviously said that casually, and then did not continue to ask anything below.

Without waiting for Xu Yun to answer, he walked towards the back row with a smile on his face.

Tang Yanshan and He Antai only bowed slightly, and followed closely behind Qin Xiangxin.

The organic students in the back row saw the dean and the two professors coming over and hurriedly gave up their seats.

"Dean."

"Sit here."

"Okay."

Qin Xiangxin didn't refuse, and sat down after casting an appreciative look at these students.

As the open class officially began, the classroom, which had little space left, became very quiet again.

It is not an exaggeration to say that it is a pin drop that can be heard.

Everyone was listening to the lecture with full attention, for fear of missing an important part.

It turns out that Xu Yun did not disappoint everyone, following the courseware he talked about the origin of abstract algebra to the extension.

and the various branches included.

Group Theory.

Ring Theory.

The Galova Theory.

Linear algebra.

In addition to this, he also explained with practical examples, presenting an abstract algebra that is no longer abstract.

And soon the people in the classroom were also surprised to find that there seemed to be a kind of magic in what Xu Yun was telling, which made people involuntarily immersed in it and would not feel bored.

This is a state that I don't usually have in class.

Abstract algebra is a difficult part of undergraduate mathematics courses, and I don't know how many people feel broken.

But now after listening to this public class, the whole person has a kind of sudden enlightenment.

It seems that abstract algebra is not so abstract either.

I don't even think it's too difficult for the example questions given in class.

Originally, most people signed up to listen to this open class, basically because of Xu Yun's fame.

While admiring the demeanor of the world's math problem provers, take a group photo and ask for an autograph or something, maybe you can bless yourself from now on and never fail the course and go ashore smoothly.

But after really listening to it, I realized that Xu Yun didn't just have the ability to prove the problem.

It is very powerful in teaching.

even had an idea in his heart, how good it would be if he could let Xu Yun be his lecturer.

The more immersed you are in something, the faster time passes, and before you know it, the two-hour public class is coming to an end.

During the period, including Qin Xiangxin, several professors frequently nodded their heads in affirmation of what Xu Yun said.

Among them, Tang Yanshan was even more secretly frightened.

I remember that when Xu Yun first entered the school, he asked him to talk to his classmates about the monthly exam questions.

At that time, he discovered Xu Yun's special talent, which was able to simplify complex problems and get to the core.

Help others understand the problem quickly.

It's just a natural teacher.

Now that such a long time has passed, he can obviously feel that Xu Yun's talent in this area has improved a lot.

Tang Yanshan himself is a professor and graduate supervisor, and in his opinion, this talent is more valuable than personal ability.

After all, cultivating a group of excellent mathematical talents is completely different from reaching a certain level on your own.

"Abstract algebra has been laid and developed by successive mathematicians and has become the universal language of most contemporary mathematics."

"I want people to be flexible with the subject and learn its branches."

"The above is all the content of today's open class, thank you for your careful listening and cooperation."

Almost the next second after Xu Yun finished his final summary, the bell rang to announce the end of the open class.

It's a perfect connection.

Although everyone was still a little unsatisfied, they had to gradually get up and leave the classroom with regret.

However, some bold students rushed directly to the podium and took the initiative to ask for autographs and group photos.

"Xu Yun, can you sign for me?"

"I want to take a picture."

"When will there be an open class, today's abstract algebra lecture is really good."

"It's really strange to say, I can't understand how I hear other professors talk about abstract algebra, but today I actually have a feeling of understanding."

"It's worthy of Xu Shen, it's really good."

Originally, everyone subconsciously wanted to call Xu Yun as a teacher as soon as they came up, but when they thought that the other party was an undergraduate like themselves, they quickly changed it to Xu Yun.

Xu Yun didn't mind anything in the face of such enthusiastic students, and basically met everyone's requests.

Qian Yudong, who was standing at the bottom, looked at Xu Yun, who was surrounded by everyone on the podium, and his face was full of relief.

"It's worthy of someone who came out of our dormitory, and he didn't embarrass the dormitory and me, the head of the dormitory."

After speaking, he didn't forget to turn his head to look at Zhou Qi and Zhao Yuefeng behind him.

"You two also have to learn from Xu Yun, but you must not hold back our dormitory."

"Fight for the three kings."

Hearing that there were only three kings, Zhao Yuefeng looked suspicious and casually asked Qian Yudong.

"What about you?"

"Of course I'm relieved to make a bronze, and the three kings can take me to fly no matter what." Qian Yudong raised his head and replied openly.

Suddenly ushered in the white eyes of Zhao Yuefeng and Zhou Qi.

"We despise you."

Qin Xiangxin, Tang Yanshan and He Antai seemed to have something to say to Xu Yun, and they did not leave as soon as the public class ended, but continued to sit in place and wait, and only got up after there were not many people on the podium.

"This open class is awesome, I wonder if you have any plans to stay in school in the future?"

Qin Xiangxin stopped beside Xu Yun, highly praising his performance in the class just now and throwing out a question.

After listening to this open class, he had a new plan for Xu Yun.

Since Xu Yun wants to continue his studies and has no time to start classes often, let him be bound to the school first, and then he can stay in the school to teach directly after graduation.

Xu Yun hadn't thought about his plans for graduation for the time being, and suddenly heard Qin Xiangxin's words and didn't answer immediately.

Just as he was thinking, He Antai's voice suddenly sounded in his ears.

"Dean Qin's proposal, you can consider it carefully, maybe you will be the youngest professor in our Beijing University in the future."

"I'll think about it." Xu Yun nodded and replied when he heard this.

"You don't have to feel any psychological pressure, anyway, if you do a Ph.D., it's still early to graduate." Qin Xiangxin noticed Xu Yun's expression, raised his hand and explained with a smile and added, "Just come to me directly if you think about it." ”

At this time, Tang Yanshan next to him couldn't help listening to the conversation of several people, and couldn't help but take the initiative to interject.

"Xu Yun."

"Your talent for lecturing is getting stronger and stronger."

"Honestly, even I'm a little envious."

He is really right, for a teacher, students can easily understand and grasp what they are saying, which is the greatest affirmation of his teaching level.

Xu Yun naturally understood what Tang Yanshan meant, and with the great improvement of his various abilities, he was able to analyze the core essence of the problem very simply, and summarize the law, and it became easy for students to learn this law.

It is conceivable that when he completes his graduation thesis, he will get the advanced task reward, so that his abilities will be improved again.

This capability advantage will be further increased.

If you look at it this way, if you become a professor yourself in the future, it will be a bit of a waste without a few students.

"Maybe it's because my understanding of mathematics has deepened, and I know better how to tell a problem."

"That's probably why." Tang Yanshan agreed with Xu Yun's answer, nodded and shifted the topic to another matter: "How is your undergraduate thesis completed?" ”

"Now that I have a direction, I will ask Professor Tang for advice when I finish the first draft." Xu Yun replied truthfully.

But as soon as the words fell, Tang Yanshan hurriedly waved his hand.

"When the thesis is completed, you can set a date for defense, and I don't necessarily have a higher level than you when it comes to the thesis."

Tang Yanshan naturally did not guide Xu Yun's thesis, in his opinion, Xu Yun's graduation thesis must be related to Hodge's conjecture, after all, as a world's mathematical problem, it can be sent to core journals casually, let alone guidance, I am afraid that he may not be able to fully understand it.

So in order to avoid this embarrassing situation, it is the best way to let Xu Yun write his graduation thesis by himself.

When Qin Xiangxin heard about the graduation defense, a mysterious smile suddenly appeared on his face.

specially reminded Xu Yun.

"In order for you to successfully complete the defense, I said hello to the math club."

"At that time, ten well-known domestic mathematics professors will be organized to form the most authoritative defense jury, and you must play well at that time, so as not to finish your studies in the end."

Hearing this, Xu Yun's face stiffened, and he couldn't cry or laugh in his heart.

"Dean."

"Isn't this lineup a little too over-spec?"

"It's just a defense of my undergraduate graduation."

"Otherwise, how can we show that our Beijing University attaches great importance to you, and we can still count on you for the development of mathematics in our country in the future." Qin Xiangxin stretched out his hand and patted Xu Yun's shoulder, and said earnestly.

Thank you for the 100 coin reward from Qiankunju!
