Time passed quietly, and the same scene was constantly playing out in the mathematics class examination rooms of 15 colleges and universities: the candidates looked at the test questions on the test paper with expressions of embarrassment, as if they were suffering and couldn't express their pain.
Basically, more than 95% of people are like this, and the remaining less than 5% of candidates have been exposed to mathematics academics before and have read several mathematics papers.
But even if I have read several mathematics papers before, I feel uncomfortable when faced with such a question.
However, just like the judgment made by Xiao Yi, the first clip is after all a relatively unrestrained clip among the academicians, and among the students taking the exam, there are many geniuses of all kinds, especially Shangjing University.
After all, Shangjing University's Mathematics School has the title of the first department of the first university. The most basic requirement for their mathematics class is for students to obtain a good enough ranking in Math Olympiad.
Therefore, students gradually contacted Principle of Inclusion-Exclusion based on the methods used in it, and then, students who ranked second, third, etc. finally answered on the test paper.
As for the first student...
"Huh? USTC A student has handed in his paper in the examination room."
Someone said in the remote proctoring online conference room.
"Hand in the paper now?"
Others were confused.
This exam has only passed for half an hour, and someone has already handed in the paper?
Could it be that you gave up?
While everyone was thinking, the surveillance screen of the USTC examination room was also called up and placed on the main screen of the conference room.
Sure enough, they all saw a student standing up from his seat and walking towards the front of the examination room with his test paper.
Academician Liao Huan from Beijing University saw it and immediately laughed, "Hahaha, Old Hu, the psychological quality of the students you recruited this time is not very good, so you are giving up?"
However, in the face of Liao Huan's ridicule, Hu Guangde was not anxious at all.
He first glanced at the student, and then a smile appeared on his face, "Old Liao, Old Liao, you made a mistake this time."
Liao Huan was stunned for a moment, and then frowned. How could this old guy not be angry in the face of his ridicule, but still look like he was sure of victory?
"What do you mean?"
Hu Guangde laughed, and then introduced him calmly, "This student's name is Xiao Yi."
Liao Huan immediately thought of it, "Oh, that's what you said before, your Hui Province's top pick this year was originally going to come to our school?"
Hu Guangde nodded slightly.
Liao Huan frowned. "The exam has only started for 30 minutes. Do you think he has finished writing?"
"It's not impossible. Although these two questions seem intimidating, they are only for these freshmen. For those who have really entered the academic research of mathematics and have written papers, the difficulty of these two questions is relatively low." Hu Guangde smiled and said, "I forgot to tell you, didn't I just say that I recently read a paper written by a student, and that paper was posted by Xiao Yi."
"What?!"
Upon hearing Hu Guangde's words, not only Liao Huan was surprised, but other academicians and professors in the conference room also looked surprised.
A high school student wrote an essay?
This...
How is that possible?!
"Are you lying?" Liao Huan said suspiciously, "It's a small paper, right? Whether it can be published in a general journal is a question."
Hu Guangde laughed loudly. He was about to say that the email sent by Xiao Yi was from IHES, but then he thought about it. Xiao Yi had not yet received an email confirming receipt, so he should be careful first.
So he said, "Don't worry, what I can say is that when his paper is published, it will definitely cause some fluctuations in our mathematics community."
"Oh, right." Hu Guangde raised another finger. "Also, there is one more thing I forgot to mention. This morning's test paper, Xiao Yi, was completed and handed in in 20 minutes."
This time, the academicians present were shocked again.
The morning test paper was finished in 20 minutes?
Although the test papers in the morning were far inferior to the questions they asked in the afternoon, the difficulty of those questions was also recognized by them.
If you can finish it in 20 minutes...
"Quickly, send this student's answer sheet over and take a look." Liao Huan said immediately, could this student really be able to answer the questions asked by so many of their academicians?
"Uh... Academician Liao, this may not work." Professor Liu Min from Qinghua said, "The exam is still in progress and it is not over. Candidates' test papers cannot leave the examination room."
"However, according to the cross-marking groups we divided by drawing lots before, it seems that USTC where Academician Hu is located and Academician Liao where you are at Beijing University will exchange test papers for marking, so you can still see this test paper when you grade today."
After hearing what Professor Liu said, Liao Huan could only give up the idea of reading the Xiao Yi test paper now.
However, not being able to see it for a while only made him more and more curious about the Xiao Yi test paper.
Of course, academicians from other major universities were also very curious. They finished writing this new type of question they asked in half an hour. This student named Xiao Yi was indeed a bit extraordinary.
Other academicians all said to Liao Huan, "Old Liao, remember to tell us the results when you get the results during the evening marking to see how many points this Xiao Yi can get."
Seeing that everyone else showed interest in Xiao Yi, Hu Guangde smiled.
Stay interested!
Anyway, Xiao Yi is now their student USTC, and they will all envy USTC by then!
Especially Liao Huan, an old man, seeing his impatient expression now makes Hu Guangde feel so happy!
At the same time, Ke Senior Colonel is in the park.
Xiao Yi, who had finished his exam, didn't know that there was an online conference room, and even a group of academicians were remotely monitoring the exams of their fifteen universities. Now these academicians are also interested in his test paper.
At this time, he was walking around the campus aimlessly.
However, his eyes showed that he was deep in thought at this time.
At this moment, his mind was filled with the second question in the exam just now.
Zhang Yitang In that paper, a stronger version of the Bombieri-Vinogradov theorem was developed, as well as the method used in this part [Sieve Method].
Today, after carefully thinking about the fragment selected by the academicians and the prompts given on the test paper, Xiao Yi's once piecemeal thoughts gradually formed a unified prototype of an idea.
Where this unified idea will eventually lead, he has no idea yet.
If it hadn't been for this incident, he could actually have left the examination room 10 minutes earlier.
"But one thing is for sure, I'm getting closer to the answer to a question!"
Wisdom shone in his eyes.
