"This ......" Duan Yun was stunned when he heard this.

Having a high school dropout teach more than a dozen professors and experts is obviously an unbelievable thing to do.

"Duan Yun, what do you say, anyway, the paper was written by you, it really can't be fake, you just have to boldly explain this paper!" At this time, Guo Haitao also stepped forward and patted Duan Yun's shoulder and said.

"Ahem, okay. Hearing this, Duan Yun had no choice but to nod and agree, and then said to Taishan behind him: "Vacate these shelves and settle these teachers to sit down." ”

Due to the cold weather, it was impossible for Duan Yun to lead these people to the backyard to give lectures, so he needed a larger place to give lectures, so he could only vacate the supermarket shelves.

"Hey. Tarzan answered, then turned and walked away.

The next moment, under the horrified gaze of everyone, Tarzan moved the heavy-looking shelves to the wall very easily, like a sack, and the hall quickly vacated a huge piece of space.

After arranging for the professors to sit on the bench and the matza, Duan Yun took the copy of his paper on the Hodge conjecture from Guo Haitao.

Under Duan Yun's instructions, Taishan found another plywood and a stone pen and placed them beside Duan Yun.

"Let's get started. Seeing that everything was ready, Jiang Chengdong, who was sitting in the front row, motioned for Duan Yun to speak.

If the scene appeared on TV or newspaper media, it would definitely shock the entire education and academic circles!

More than a dozen top experts in mathematics and a president of Huaqing University sat neatly on a small horse and sat in a row, listening to a lecture by a dropout who had not yet graduated from high school, which was almost unimaginable to ordinary people!

This is definitely a glorious moment in Duan Yun's life!

"Ahem!" Duan Yun cleared his throat, wiped his shiny bald head, and said with some excitement: "Dear teachers, professors and principals, first of all, I welcome you to come to my house as guests, this is my honor Duan Yun......"

"Don't talk nonsense, hurry up, pick the key points!" Guo Haitao in the audience motioned to Duan Yun to hurry up to the point.

"Okay, okay. Duan Yun nodded again and again when he heard this, and then said, "The Hodge conjecture is a major unanswered question in algebraic geometry. Proposed by William Valens Douglas Hodge, it is a conjecture about the correlation between the algebraic topology of a nonsingular complex algebraic cluster and its geometry expressed by the polynomial equation that defines the subcluster......"

As he spoke, Duan Yun used the stone pen in his hand to write and draw on the plywood, listing a string of formulas.

Everyone's eyes were firmly fixed on Duan Yun's body.

"My basic idea is to ask to what extent we can take the shape of a given object by gluing together simple geometric building blocks of increasing dimensions. This technique has become so useful that it can be promoted in many different ways......"

Duan Yun had been studying this Hodge conjecture for a while, so he didn't need to look at the paper in his hand at all, he was completely explaining it off the script.

Seeing this scene, Jiang Chengdong's face finally showed a trace of surprise.

Until they came here, Jiang Chengdong and the others still couldn't believe that Duan Yun, a student who hadn't graduated from high school, could really crack this Hodge conjecture, and they were more willing to believe that this paper should be written by Guo Haitao, but they didn't know why they deliberately put it on Duan Yun's head.

But as soon as the connoisseur makes a move, he knows if there is one.

At this time, Duan Yun's Duan Yun was completely off-script explanation, and the formulas on the blackboard were written very skillfully, judging from these small details alone, Duan Yun was obviously very familiar with this paper, even if the paper was not written by him, he must be very familiar with the content of this paper!

This surprised other mathematicians present, and many people focused on Guo Haitao.

But then, as Duan Yun gradually entered the state, the speed of his explanation began to get faster and faster.

“…… In this step, we talked about N+, press is Kasa, sprinkle a sass

Duan Yun's thinking was very fast and logical, he not only told the steps to solve Hodge's conjecture, but also said his specific thoughts and understanding when he first solved the problem.

Explaining mathematical theories is actually a very boring thing, but Duan Yun himself is a master mathematician, and his eloquence is also very good, so his entire explanation process is colorful and sounding interesting.

So much so that after a while of the explanation, the atmosphere on the scene suddenly became more active, and the interaction between Duan Yun and these professors began to increase.

"Duan Yun, I would like to ask, to get all the prime numbers that are not greater than a natural number n, you just need to cross out all the multiples of the prime numbers in 2-n, so how do you think that if n is a composite number, it has a factor d that satisfies 1. At this time, a math professor wearing glasses suddenly asked Duan Yunfa.

Although Duan Yun explained very skillfully and clearly, there were still people asking Duan Yun questions from time to time.

In fact, the reason why these professors are like this is to touch Duan Yun's knowledge in mathematics, in the final analysis, they are still full of doubts that a high school student can solve such a world problem, so they want to try to find out the 'loophole' of Duan Yun's academic fraud by knocking on the side.

“…… Frankly speaking, I was blinded, but later I found out that I was actually blinded!" Duan Yun said with a raised eyebrow.

"Hahaha!" As soon as Duan Yun's words fell, bursts of laughter suddenly sounded at the scene, and the atmosphere in the supermarket suddenly became relaxed and happy.

And Guo Haitao, who was sitting in the front row, couldn't help but smile and nod when he saw this scene, he was obviously very satisfied with his apprentice's performance.

As for Jiang Chengdong next to Guo Haitao, his face also began to become a little excited.

Even if Jiang Chengdong is not an expert in mathematics, judging from the interaction between Duan Yun's lectures and lectures on the spot, he can basically conclude that this paper should have been written by Duan Yun nine times out of ten!

Thinking of the last dinner, I learned that Duan Yun had also won the honor of the champion of the National Mathematics Olympiad, and in this regard, Duan Yun was obviously a rare mathematical genius in the world!

At this time, these mathematics experts and professors present came here just to verify whether Duan Yun was really the author of this paper, while Jiang Chengdong thought more.

Jiang Chengdong knows very well that once Duan Yun's paper is published, it will definitely bring great shock to the entire Chinese academic community!

The threshold of the academic world is high, and there are many factions, Duan Yun can be said to be famous at a young age, and his future is limitless, if he can include such a rare genius in his own 'faction', it will undoubtedly be of great benefit to his prestige in the academic world in the future, and even his future career!

Thinking of this, Jiang Chengdong had a new plan in his mind......
