Volume 1: Student Life Chapter 273 Itinerary Confirmed
"You're going to the United States in a week, right?" Yang Yiyi, who was beside Chen Zhou, asked with her head tilted.
"Yes." Chen Zhou nodded gently. "The academic conference starts on the 15th. Dean Sun and I should set off the day before."
After a pause, Chen Zhou smiled and asked, "What gift do you want?"
Yang Yiyi tilted her head and thought for a while, then said softly, "If I bring back the ice cream, it will melt, right?"
Chen Zhou was stunned when he heard this, and then he gently scratched Yang Yiyi's nose: "Want to eat ice cream?"
Yang Yiyi wrinkled her nose, smiled and nodded.
"Let's go." Chen Zhou simply tidied up the things on the table and stood up.
"Hehe, okay." Yang Yiyi stretched and stood up.
When Chen Zhou saw Yang Yiyi stretching, he couldn't help but think, this girl has such a good figure, is it because she loves sweets?
But why do I only gain weight where I should?
Noticing Chen Zhou's eyes, Yang Yiyi reached out and put her hand on Chen Zhou's arm. As she exerted force, she heard a low cry from Chen Zhou.
“It hurts, it hurts…”
"Hmph!" Yang Yiyi snorted softly and slowly loosened her hands.
Walking out of the library, Chen Zhou was still rubbing his pinched arm. Can eating sweets also help gain strength?
"Does it still hurt?" Seeing Chen Zhou's actions, Yang Yiyi felt a little distressed again.
When Yang Yiyi's eyes met, Chen Zhou let go of the hand that was rubbing his arm, and instead grabbed Yang Yiyi's hand, saying with a smile: "It doesn't hurt anymore, but..."
Yang Yiyi asked doubtfully, "But what?"
Chen Zhou came up to Yang Yiyi and whispered, "But my wife has a great figure~"
"You, have no shame..." Yang Yiyi was about to take action, but found that both of her hands were tightly grasped by Chen Zhou.
"Haha, you can't hit it, right?" Chen Zhou replied with a smile.
Yang Yiyi thought about it and suddenly bit Chen Zhou's arm.
"Oh my god..." Chen Zhou quickly let go and jumped away.
After taking a look at Yang Yiyi who was ready to fight, Chen Zhou immediately said, "Yiyi, I was wrong..."
Yang Yiyi didn't really want to hit Chen Zhou again. There were so many people watching around. She had heard someone say, "Ah, the dog food is poisonous. There is material in the post on the campus network again..."
Yang Yiyi pulled Chen Zhou and left quickly.
Chen Zhou secretly thanked the classmates around him who were addicted to dog food, and said that he must sprinkle more dog food next time.
This is safe ...
November 10th.
There are five days left until the MIT mathematics academic conference begins.
Chen Zhou received a message from President Zhou, which was the flight information.
By the way, Dean Zhou also explained the travel arrangements.
There were five people in total who went to the academic conference this time, including Chen Zhou and Dean Sun of the School of Mathematics, as well as three professors.
This was the first time Chen Zhou heard of two of these names.
But he had heard of the other one a long time ago.
Xu Chenyang received his Ph.D. from Princeton University, the top university in mathematics, received the National Outstanding Young Scientist Fund last year, and was named a Changjiang Distinguished Professor at Yenching University.
This is a genius mathematician who was once known as "God Xu" at Yanjing University.
He is also known as the eldest brother of the “Three Musketeers of Yan University”.
The "Three Musketeers of Yan University" refers to Yun Zhiwei, Zhang Wei, and Zhu Xinwen, all of whom were undergraduate students of the class of 2000 at Yan University.
However, the current “Three Musketeers of Yan University” have all stayed in the United States to teach and have not chosen to return to China.
They are also known as the "golden generation" of Yanda mathematics.
After Chen Zhou solved the hail conjecture, he also heard a lot of comments comparing him with them.
However, no matter good or bad, Chen Zhou doesn’t care much.
So Chen Zhou was not surprised when he learned that Xu Chenyang would also go.
After all, there are many benefits to participating in more such academic exchange opportunities.
As the leader of the new generation of Yanda University, Yanda will not miss this opportunity to cultivate talents.
But Chen Zhou had never met this "senior brother" at the Yenching International Center for Mathematical Research, but this time they could communicate on the road.
Although senior brother Xu Chenyang's research is mainly in the field of algebraic geometry, no mathematician can resist the charm of number theory.
After the itinerary was confirmed, Chen Zhou finally began to prepare the content of the 30-minute report.
Through the "training" of the last hidden task, Chen Zhou already knew that a true master of speech does not need a script.
Those prepared manuscripts are only for those who are not prepared.
Does a man like him , who has already engraved the proof of the hailstone conjecture in his mind, still need a speech?
It took Chen Zhou nearly half an hour to make a simple PPT and post some core proof processes on it.
Well, I still have to make a PPT...
After the PPT is completed, save it, copy it to a USB drive, and you're done.
Chen Zhou turned around and plunged into the world of Cramer's conjecture again.
He had a new idea about Cramer's modified conjecture.
"If we look at the Cramer correction conjecture more closely..."
Chen Zhou made a table of numbers on a piece of draft paper.
This number table is not the list of composite numbers used to prove Erdős' conjecture.
Instead, it was obtained by Chen Zhou after making some changes based on it.
After listing the numbers, Chen Zhou took a pen and started counting.
The statement of Cramer's modified conjecture is, (Pn+1≤N)max(Pn+1-Pn)≈logN(logN-loglogN)+2.
What Chen Zhou circled here are the numbers that meet the requirements of (Pn+1≤N)max(Pn+1-Pn) and logN(logN-loglogN)+2 respectively.
This method is actually somewhat similar to the sieving method.
The sieve method is also called the Eratosthenes sieve.
The specific method is to arrange N natural numbers in order first.
1 is neither a prime number nor a composite number, so just cross it out.
2 is a prime number, keep it.
Then cross out all the numbers after 2 that are divisible by 2.
The first number after 2 that is not crossed out is 3, so keep 3.
Then cross out all the numbers after 3 that are divisible by 3.
By analogy, all composite numbers not exceeding N will be screened out, leaving only all prime numbers not exceeding N.
Of course, this is just a simplistic statement.
The sieve method has a wide range of applications, from the four color theorem, to the construction of infinitely many two-way connected regions, to the study of Goldbach's conjecture, and so on.
The person who applied the screening method to the extreme was Mr. Chen.
This old gentleman, who advanced the Goldbach conjecture to "1+2", brought the sieve theory to its peak in the process of studying the Goldbach conjecture.
Until now, no further progress has been possible.
Chen Zhou naturally knew that the application of screening method had basically reached its limit and it would be difficult to make any further breakthroughs.
But it did not prevent him from looking for ideas from this aspect.
"If we use the sieve formula to verify that (Pn+1≤N)max(Pn+1-Pn)≈logN(logN-loglogN)+2..."
As time went by, Chen Zhou gradually frowned.
"The Cramer correction conjecture itself is an approximation. If we use a formula, it is not equivalent..."
"On the contrary, if we continue like this, we will end up back at Cramer's conjecture itself..."
Chen Zhou put down his pen, temporarily turned away from the research at hand, and opened the document on the computer to read it.
As he watched, his eyes suddenly lit up.
