"Isn't it right? Gao Peicai only scored 32 points this year? He still had perfect scores last year, why is he worse this year than last year?

If he scores 32 points, will it be a gold medal or a silver medal?

Is this year’s IMO difficult? Is there anyone with perfect scores?”

Zhang Qiuyu and the others were discussing this year's IMO results, and it was Ding Daoliang who asked this question.

Ding Daoliang was also very surprised after learning that Gao Peicai's score in the International Mathematical Olympiad this year was 32 points. He felt that maybe he could have scored 32 points a year ago. This should not be Gao Peicai's strength.

"gold medal.

I haven't seen this year's IMO test questions, so it's hard to judge how difficult they are. However, when I visited Tieba before, I heard that this year's questions were more difficult than last year.

As for why Gao Peicai only scored 32 points this year, who knows, maybe it’s because he already won a gold medal with a perfect score last year, so he doesn’t pay as much attention to it imo this year as last year.

After all, there is no such a strong competitor as Zhao Xiancai this year, so he has slacked off.

There are some who get perfect scores, but there is only one person who got perfect scores, and he is Canadian and Chinese.

The highest score for our national team this year is Yu Chengjie, a sophomore from East China Normal University, with 41 points, just one point short of a perfect score. He also chose Peking University, and he is among the freshmen reporting for the start of school today.

However, I heard that the Canadian who got perfect marks this year is another genius, and he seems to have won the gold medal in the International Mathematical Olympiad for the fifth consecutive time."

Zhang Qiuyu said.

"Fifth time in a row? So how old is he this year?"

"You seem to be 18?"

"18? Five years ago, you were 13 years old. At the age of 13, you participated in the International Mathematical Olympiad and won the gold medal. This guy is awesome. He is indeed a genius."

"I have to say, it seems like there are so many geniuses every year."

"I think he is still not as good as Zhao Xiancai. I guess this year's IMO questions should be no different for Zhao Xiancai than last year."

When they said this, Zhang Qiuyu looked at Zhao Xiancai, and Zhao Xiancai also looked at Zhang Qiuyu after hearing them say his name.

"It's okay, you continue.

People are now focusing on the unresolved problems, so they won't pay attention to the games of these high school students.

Those who participated in the IMO competition with Zhao Xiancai last year should not be as perverted as him this year and have studied all the required undergraduate courses by themselves, right?"

Zhang Qiuyu continued, but no one answered his last words.

"How is the overall performance of our national team this year?" Cuipinger asked.

"This is the only regret this year. The team champion this year is the United States, and we are second again like in 2012."

Speaking of this, Zhang Qiuyu said with some disappointment.

As for Zhao Xiancai, he continued busy with his own affairs after Zhang Qiuyu said it was okay.

"Don't be so disappointed. The team championship in the IMO competition looks better. What does it mean?

It represents nothing.

As said on the Internet, after all these years, we still haven’t had a Fields Medal winner in our country.

Our responsibility now is to study hard, study hard, and do our own thing well, look at Zhao Xiancai."

Seeing that Zhang Qiuyu was a little disappointed when he said this, Ding Daoliang comforted him.

Hearing that they mentioned him again, Zhao Xiancai also looked at Ding Daoliang again, and when he saw that nothing was wrong, he was ready to continue busy with his own affairs.

"Zhao Xiancai, as soon as your military training ended, you started reading these English materials again every day. What are you doing? Are you preparing to write a paper again?"

When Ding Daoliang saw Zhao Xiancai looking towards him, he brought the topic to Zhao Xiancai.

The last time Zhao Xiancai wrote a paper, they had never seen Zhao Xiancai read so many English documents.

"Well, I'm doing new research, but it's too early to write a paper." Zhao Xiancai explained.

"Are you really preparing a new paper? What are you planning to study this time?"

After listening to Zhao Xiancai's explanation, Zhang Qiuyu also asked curiously.

"It's about the Erdős arithmetic sequence conjecture." Zhao Xiancai said.

"What's the arithmetic sequence conjecture?"

After listening to Zhao Xiancai finish what he was studying, Ding Daoliang and the other three looked confused. They knew about the arithmetic sequence. They had learned it in their freshman year of high school, and they had done countless arithmetic and arithmetic sequences in the three years of high school.

Mathematics problems related to sequence.

But they had never heard of the arithmetic sequence that Zhao Xiancai was talking about. Therefore, he also began to wonder in his mind whether they were mathematics majors. How come they hadn't heard of anything Zhao Xiancai said casually?

After looking at each other and realizing that the expressions on other people's faces were the same as theirs, they determined that it was not that they were not paying attention in class, or that their knowledge was too narrow, but that what Zhao Xiancai was studying was to them.

Maybe it's a little less popular.

After all, although they are students in the School of Mathematics at Peking University, they are only in their sophomore year after all.

"What is this research about? What is the specific content of this conjecture?"

Zhang Qiuyu asked Zhao Xiancai again.

"It's called Erdös's arithmetic sequence conjecture. It must be a study of arithmetic sequence. The Erdös in front is the name of the person who proposed this conjecture, just like the Riemann Hypothesis and Goldbach's Hypothesis.

The content of this conjecture is that if the reciprocals and divergences of all elements in the sequence, then the sequence should contain an arithmetic sequence of any length."

Zhao Xiancai explained.

"Let me go, are you going to prove the conjecture into a theorem or overturn this conjecture? This is too awesome. This is much better than the previous Riemannian and other solvability.

Have you found a mentor?"

After hearing Zhao Xiancai's explanation, before Ding Daoliang and Cui Pingge could react, Zhang Qunshan said with a look of surprise.

The content of this conjecture was not difficult, and they all understood it after Zhao Xiancai explained it.

But understanding the problem does not mean that they can understand whether it is difficult or difficult to solve the problem. After all, no matter how difficult or how difficult it is, they cannot solve it.

Although Zhang Qiuyu didn't know how difficult it was to solve this problem, he knew that it was definitely not an easy task to prove a conjecture into a theorem or to overturn this mathematical conjecture.

If this was a simple matter, this conjecture would have been overturned or proven and turned into a theorem long ago.

"No, don't I look for information on the Internet and read literature every day?

The difficulty is higher than the previous "Solubility of Singular Integral Differential Equations in the Riemann-Hilbert Problem", but precisely because it is much more difficult, the progress is also slow."

Zhao Xiancai also complained to his roommates.

"The Erdós Arithmetic Sequence Conjecture, also known as the Erdós-Turán Conjecture, is derived from...

Paul Erdos was born on March 26, 1913 and died on September 20, 1996 in Warsaw, Poland. He was regarded as a child prodigy in his childhood. He published a total of 1,475 papers in his life and collaborated with 511 people. The number of papers ranked first in mathematics history.

The best of the family..."

Cui Pingge also quickly found relevant information.

…

Regardless of whether Zhao Xiancai can turn this conjecture into a theorem in the end, at least Zhao Xiancai has been thinking about solving such a problem since his sophomore year. This is something Zhang Qiuyu and the others cannot possibly do no matter what they do.

Therefore, after that night, Zhao Xiancai and other people in his dormitory began to gradually call him "Zhao Shen". This was not a compliment, but something they said from the bottom of their hearts, and they really felt that way.
