High in the sky, a flight from Beijing to Charles de Gaulle Airport in Paris, France, is flying smoothly in the stratosphere.

Jun Xin ignored the eyes of the clerk from the foreign affairs department who was sitting next to him, picked up a document and looked at it with relish. The document was sent to Junxin by Wei Donglai the day before Junxin left Beijing. The above content is the kink table of the thirteen nodes of kinks that Junxin gave him as a research topic.

The officer of the foreign affairs department has been staring at Junxin for a long time, as a high-achieving student who graduated from Shanghai Foreign Chinese University, and successfully entered the Ministry of Foreign Affairs after graduation, a smooth sailing life gave him a kind of arrogance hidden in his bones. Although he showed a humble appearance because of the needs of work, Junxin could faintly feel his arrogance. This is also the reason why Junxin only said hello to him since he got on the plane, and then ignored him again.

"What are you looking at?" That Officer Sun couldn't help but ask in the end. Usually, because he is familiar with the place he is going, it is usually the people he leads who ask him about the situation in that country. Even if some people didn't ask about these things, they would not snub him as a foreign affairs leader. There are not many cases of Junxin.

In the academic world, there are generally only a few master-level people in the academic world who do not shy away from him. However, today he met a person dressed as such a young student who didn't care about his actions, and for a while he couldn't help but be curious about Junxin.

Jun Xin didn't raise his eyelids, and said with an expression unchanged: "You can understand it as a high-level mathematical paper." ”

"Isn't it just a form?"

"Oh!" Junxin replied indifferently, "Then English is only 26 letters!" ”

"Ugh!" Director Sun was speechless for a moment.

"What are you doing in Canada?" Director Sun decided to chat with Junxin on a different topic. said that it was a chat, but in fact, I just wanted to understand the person and things of Junxin, but fortunately, after returning to the ministry, I had enough talking points to brag with others.

Junxin's expression was calm, and he kept saying in his hand: "It's nothing, go to Canada to attend a conference." ”

"Meeting?" Officer Sun looked Jun Xin up and down, and asked a little disbelievingly, "Just you?" ”

"I explained it when I filled out the immigration form." Jun Xin explained, he naturally knew what Secretary Sun's suspicions were about him. "Didn't you read the form?"

Director Sun was dumbfounded, he naturally read the form, but he didn't study it carefully, he glanced at it roughly, and only went out to study abroad like Junxin.

"Let's talk about the schedule!" Director Sun, who had eaten two stuffy, changed the topic again, "We..."

Just made a start, Junxin said: "The plane is a flight at eight o'clock in the evening, it takes eight hours for us to arrive at Charles de Gaulle Airport in France, so we arrive in France at about two o'clock in the morning, according to the plan we will stay in France for a day, the next morning from France to Toronto, Canada, at half past seven in the morning, it takes about six hours, and you can arrive at about half past one in the afternoon, and then the organizing committee will come to pick me up, the hotel has been booked, and the conference venue has been selected. You don't have to worry about that. ”

After listening to this, Director Sun said a little annoyed: "Then let's talk about foreign affairs discipline!" ”

Jun Xin shook his head and said: "Foreign Affairs Discipline No. 1: No ........." In the stunned eyes of Director Sun, Jun Xin recited all the regulations of foreign affairs discipline in a turbulent tone.

"There are so many regulations that can't be enforced after you put them on your back, and I will supervise you." In the end, Secretary Sun could only come up with such a dry sentence, and ignored Junxin.

Jun Xin finally glanced up at Mr. Sun and said, "Remember, never interrupt a mathematician's thinking, because they will embarrass you. It's just a small mismatch. After finishing speaking, Junxin no longer paid attention to Director Sun's stunned eyes, and continued to devote himself to his own research.

He really didn't say anything wrong, because Junxin was doing his own research. The kink table of thirteen nodes that Wei Donglai brought to him was quite enlightening to him.

The kink table of thirteen nodes is not just such a simple table, it includes not only the table of nine nodes, but also the kink table of eleven nodes, and after having these tables, Junxin can even deduce a kink invariant by himself, although it seems to him that it will take quite a long time.

Traveling on the plane seems to Junxin to be very boring, but fortunately, he can study the most advanced scientific research results at the moment, so at this time, he has something related to his own discipline and research in hand, and he can quickly devote himself to research. Junxin was immersed in this thirteen-node kink table.

Although it is the International Union of Crystallography that is about to participate, it does not mean that Junxin must only think about the theories and problems related to quasicrystals and crystals, on the contrary, Junxin really does not think too much about these problems, but has been studying the related problems of superstring theory and kinks. Especially when Wei Donglai's kink table gave him a hint of inspiration. That's why he was a little annoyed when he was interrupted by Director Sun, although his performance was very bland.

However, Director Sun didn't know what Jun Xin thought, so he didn't have a good face for Jun Xin, and the two of them were a little more serious for a while. It's just that Junxin is much better when he breathes, but Director Sun is still angry.

"During my day in France, I will go to the École Normale Supérieure in Paris, France, and maybe I can meet a few people I know to talk about math problems together, and you can do it yourself." After retracting his gaze, Junxin spoke slowly.

"What are you doing over there?" But after all, he was from the Ministry of Foreign Affairs, and although he was a little angry in his heart, he could quickly regulate his emotions and asked.

"As the world's two major mathematics centers and the European mathematics center, it would be a bit unreasonable if you didn't look at it as a mathematician." Junxin glanced out the window and said.

"Maybe they won't let you in!" Director Sun said sarcastically, which can be regarded as a little sarcasm of Junxin.

"Is that so?" Junxin replied casually, "But my name should be enough for Mr. Janissary to let him go." ”

"You? What fame can you have? In Europe? ”

"Why don't you come along and have a look?" Junxin didn't answer, but asked rhetorically.

"Just go!" Director Sun snorted and said.

Jun Xin pursed his lips and did not speak, to be honest, his research has enough weight to enter the mathematics department of any university in the world, even Princeton and the École Normale Supérieure in Paris. Moreover, the École Normale Supérieure de Paris and the Institut des Hautes Etudes de Paris have always been the center of algebraic geometry, and the Modell conjecture and Junxin's inference made by Junxin are cutting-edge problems about algebraic geometry.
