"Okay. When Duan Yun heard this, he had to nod, he could see that he couldn't get rid of Ouyang Xiangnan.

However, Duan Yun thought about it, it didn't hurt to go abroad with Ouyang Xiangnan, after all, it was abroad, and he didn't have to worry about being embarrassed when Tang Yan found out that the two were together.

"Tell me your flight number, and I'll book a ticket." Ouyang Xiangnan said excitedly.

"Forget it, I'll let Gao Jing buy tickets for you. Duan Yun shook his head slightly, took out his mobile phone and dialed Gao Jing's number, and quickly solved the problem of Ouyang Xiangnan buying tickets.

"Go back and send your ID card and passport to Gao Jing, she will help you get it. Duan Yun put away his phone and said to Ouyang Xiangnan.

"Hmm. Ouyang Xiangnan nodded obediently when he heard this.

"By the way, I'll give you a reminder first, it's not as safe at night abroad as at home, you'd better not go out at night as a girl, and during the period of going abroad, I may be in meetings most of the time, and I don't have much time to play with you......" Duan Yun Zhengse said.

"Don't worry, I'm more familiar with the situation abroad than you, and I won't cause you trouble. Ouyang Xiangnan smiled slightly when he heard this, and said, "By the way, if you participate in the mathematicians' conference, I can also go to observe, right?"

"This ...... It's not clear, it depends on what the organizers are asking for. Duan Yun said with a frown.

"Oh well. Ouyang Xiangnan nodded, and asked again: "You can't attend meetings every day in the past few days abroad, can you set aside three or four days to see the places of interest in Europe or something." ”

"The schedule of this conference is seven days, and after the conference, I will stay in the UK for a day or two at most, mainly for shopping, after all, my relatives and friends in China know that I am abroad. Duan Yun said.

"You want to buy her a gift, right?" Ouyang Xiangnan said to Duan Yun with the corners of his mouth hooked.

"It's not easy to go abroad, so it's right to buy some souvenirs. Duan Yun said deliberately lightly.

At present, Duan Yun and Ouyang Xiangnan are already in a substantive lover relationship, so when talking about their real girlfriend Tang Yan, the atmosphere will be a little subtle and awkward.

"Don't worry, I won't interfere with the two of you. Ouyang Xiangnan looked indifferent, and only listened to her continue: "If you want to buy her a gift, then you should bring me, after all, only women know what women like the most." ”

"Well, then I'll take you with me. Duan Yun raised his eyebrows, and then said: "Hurry up and eat, you go back and prepare for dinner, let's go to the airport together tomorrow." ”

"Okay. After hearing Duan Yun's words, Ouyang Xiangnan's clear eyes flashed with joy......

……

After the meal, after the two separated, Duan Yun returned to the apartment.

Duan Yun put the clothes and laptop he was going to change abroad into his suitcase, packed them up, and put them at the door of the apartment.

Since it was the first time he stepped out of the country, Duan Yun was both excited and a little worried.

In fact, even if there is no mathematician conference, Duan Yun will definitely go abroad to take a look in the future, which is good for his vision and experience, in addition, his Clear Sky Film and Television Company also needs to open up overseas markets, and if the Hong Kong stock market makes a lot of money this time, he also plans to make some investments abroad, after all, the technical strength of many European and American companies is more developed than that of China, and as a market, there is also a lot of room for expansion.

Top professional chess players can see the five or even ten moves of the back hand, Duan Yun is not a top trader, but with the memory of his previous life, he still has to see farther than the vast majority of entrepreneurs.

Turning a national business into a global business is a metamorphosis, and it is also Duan Yun's dream.

Turning on the computer, Duan Yun saw that there were a few more new emails in his email address, and then clicked on them with the mouse.

The above emails are all high-quality scripts recently selected by the company that Chen Jia sent him, and the following one is an official email sent to him by the Mathematicians Conference.

Duan Yun then clicked on one of the emails and checked it.

This email was just sent last night, which roughly means that Duan Yun was invited to do an hour-long public report on the afternoon of the first day of the opening ceremony, hoping that he could prepare the materials for the report in advance.

After seeing this email, Duan Yun was a little excited.

Because judging from what he learned about the World Congress of Mathematicians from the Internet, it is a very high honor to be able to give a one-hour report at the World Congress of Mathematicians.

According to the general practice, the World Congress of Mathematicians will invite the world's most outstanding mathematicians to report on the conference, not everyone is qualified, and it needs to be strictly reviewed by the scientific committee of the conference before the final selection of the list of mathematicians who are qualified to give reports at the conference.

Therefore, being able to give a presentation at the World Congress of Mathematicians is already a very high honor in itself.

In addition, the report of the World Congress of Mathematicians is divided into two kinds, one is 45 minutes long, and the other is one hour long, although the length of these two reports is only 15 minutes, but in fact, the two kinds of reports are invited to the huge difference in the gold content of honor.

For example, the last World Congress of Mathematicians held in Brazil, more than 180 outstanding mathematicians from 19 fields of mathematics were selected as invited speakers on the website of the ICM (World Congress of Mathematicians) at that time, including 13 Chinese mathematicians.

Among these thirteen people, only one Chinese female scientist in Cambridge has obtained the qualification for a one-hour report, and the remaining twelve people are all doing a 45-minute report, which shows that it is a high honor for a scientist to be qualified for an hour's report, and the Fields Medal, the highlight of the World Congress of Mathematicians, can only be awarded to young scientists under the age of 40, so for many senior scientists who are old but have proud academic achievements, the qualification for a one-hour report is actually equivalent to winning the Fields Medal in the eyes of many people, at least being eligible for the Fields Medal nomination。

In addition, before the start of the World Congress of Mathematicians, mainland mathematicians have not been invited to give an hour's report for four consecutive sessions, which cannot but be said to be an embarrassing record in the Chinese mathematical community.

Duan Yun can be said to have received such treatment with the previously published Hodge conjecture paper this time, and in the eyes of many scientists in the industry, Duan Yun's winning the Fields Medal this time is almost a certainty.

This will be the first scholar in mainland China to win such a world-class top academic award, and it will also create a new history of Chinese mathematics!
