Chapter 391 These things must be used up quickly
The two of them booked a flight for the morning of June 6th, and have been packing on and off over the past few days. The place they are going to is quite far away, in a foreign country, so there are not many things they can bring with them.
No matter how streamlined it is, there are at least three large suitcases.
Xu Qingzhou leaned on the sofa, looking at the familiar living room, and suddenly felt a little emotional.
In my previous life, I went to study in the United States with only one suitcase. When I left, the rental house was so clean that it seemed as if no one had ever lived there. This time it was different. Basically nothing in the living room was touched, and it was full of life.
Xu Qingzhou and Song Yao renewed the lease of this house for two years.
The landlord, Aunt Jia, agreed immediately. They had their own house and their son worked in the United States all year round. It would be troublesome to find a new tenant if the house was empty. Besides, there were two college tycoons living in the house, and everyone praised her house for its good feng shui.
"Two people are different from one person after all."
Xu Qingzhou sighed.
Er Miao wagged his tail and finished eating the cat food at the automatic feeder. Then he slowly walked over and jumped onto Xu Qingzhou to ask for a hug.
Xu Qingzhou hooked Er Miao's chin and looked at the ceiling thinking about the next arrangements.
Although the procedures for taking pets abroad seem to be more complicated than theirs, Er Miao must be brought along, as both Mr. Song and his wife are busy. As for his family, Mr. Xu doesn't like cats and thinks Er Miao is a real waste.
The cats they raised before could be fed with just some cat food when people ate. Now they have to eat cat food, and nothing they eat works, and nothing they do seems to work.
With Er Miao around, this "family of three" is complete, but he and Song Yao are too lonely.
After a while, Ermao squinted his eyes and made a purring sound.
Xu Qingzhou sat on the sofa for a while, let Er Miao lie on the sofa and continue to sleep, and then he sat back in front of the computer.
In the past half month, he has been introducing the Reich metric based on Sir Atiyah's proof.
Suppose there is a function called "Reich metric", which is defined on the complex plane or Riemann sphere related to the Riemann Zeta function. It is a real-valued function that measures the "distance" or "difference" between two points on the manifold.
The next steps are fairly clear.
Try to find a formula that relates the non-trivial zeros of the Riemann Zeta function in a certain region to the Reich metric for certain sets of points on the manifold.
Then, using the special properties of the Reich metric, such as complex structure sensitivity and positive definiteness, theorems related to the boundedness of the Riemann Zeta function are derived.
A mathematical model is constructed to describe the relationship between the set of points on the manifold, the Reich metric and the value of the Riemann Zeta function.
Finally, prove the Riemann hypothesis.
It sounds simple, but each step is actually quite difficult.
It is just like in the process of building a building, there is not even a construction drawing, it only tells you the logic - foundation, main frame, and the building is formed.
Everything else has to be designed by yourself.
Of course, Xu Qingzhou was not without gain. Before visiting Professor Gu Zhizhong and others, he had completed the second step and derived the formula.
"Maybe there is hope."
As Xu Qingzhou spoke, he actually laughed. If it was really that simple, it wouldn't have remained unresolved.
When faced with a difficult mathematical conjecture, if people cannot attack it, they will just circle around it. Sometimes the solution will be found by circling around it, but more likely they will still need to attack it with brute force.
He found that not many folk mathematicians studied the Riemann hypothesis, and they were actually concentrated around the Goldbach conjecture and Fermat's Last Theorem.
Maybe the analytical statement of the Riemann hypothesis is too complicated?
If it is written as an equivalent proposition of the error term or the equivalent proposition of the Mertens function, more people will probably study it.
He had no hope of proving the Riemann hypothesis, but simply thought that Sir Atiyah's idea had some merit. After trying it once, he would be able to clearly understand where the problem lies.
Xu Qingzhou put aside all the random thoughts and continued writing.
"The function g(n,Pn) depends on the order n of the zeros and on the zeros themselves, and is related to the Reich metric on the manifold."
"There is a formula g(n, Pn)=∑m(n)ak(f(ρnk))qdR(f(ρnk), Pn)p"
At 7pm, Xu Qingzhou had just finished his shower and written two equations when Song Yao came back, humming a song. It looked like she had a good time today. "Are you all packed?" Song Yao looked at the two large suitcases that were zipped up and nodded with satisfaction.
"Well, I'll pack the toiletries tomorrow. Didn't you say you wanted to buy some clothes?"
"I'm moving soon, I'll buy it later."
Song Yao came over, hugged Xu Qingzhou from behind, kissed him on the face, and then went to the sofa to play with Er Miao.
"I almost forgot the most important thing." Xu Qingzhou turned around, looked at the two big white legs of Song the school beauty, slapped his head, and ran into the bedroom.
Song Yao stroked her cat twice, and seeing Xu Qingzhou's look, she followed him in. Then, she saw the boy with a serious expression just now open the second drawer and take out the things inside.
“It would be a shame to forget these things.”
"abnormal."
Song Yao looked at the various stockings in Xu Qingzhou's hand, spat, turned around and looked at the only empty suitcase, and said unhappily: "The suitcase is full."
I shouldn't have satisfied Xu Qingzhou's strange hobbies, lest he keep pushing his feet on the ground.
She originally thought that this guy would struggle, but unexpectedly Xu Qingzhou actually nodded slightly and said in a deep voice: "It does take up a bit of space. It seems that we can only use it all tonight."
"."
"Xu Qingzhou, you have to go home tomorrow." Song Yao reminded expressionlessly.
Xu Qingzhou nodded, walked over, and put his arm around Song Xiaohua's waist, "You reminded me that we should hurry up for the 11 o'clock flight tomorrow morning."
crunch~
They both fell on the bed.
"Xu Qingzhou!" Song Yao's eyes widened, she didn't react at all. She pulled Xu Qingzhou's clothes a few times, but found that she was pressed down by Xu Qingzhou.
There's a feeling of powerlessness, but besides that, there seems to be a little bit of thrilling heartbeat?
"Little girl, just struggle. The more you struggle, the more excited I am."
Rongcheng.
Wutong Community.
At 3 o'clock in the afternoon, Xu Qingzhou pushed the door open and came out of the bedroom with a smile on his face. He picked up an orange from the coffee table, broke it open and ate a piece.
"Hiss~ It's still sour."
Xu Qingzhou put the oranges back on the table. Yesterday, Wang Xiaping sent him out to buy soy sauce. When he came back, he saw an old man selling oranges on the roadside, so he weighed two kilograms.
I didn't expect that my sincerity was misplaced.
Xu Qingzhou shook his head and looked out the window. In July, the atmosphere of midsummer was already quite strong, and Chengdu had also entered the hottest month of the year. The weather outside the window was very good, and the sun fell on the balcony.
This was the seventh day since he returned, which happened to be Saturday, on June 6th. The two packed their luggage and returned to Chengdu with three large suitcases.
During the days he and Song Yao returned, they also sorted out the passport and Er Miao's procedures.
Xu Qingzhou had a simple birthday celebration on July 7, and then spent most of the rest of the time at home doing calculations.
He opened the window, walked to the balcony, and the heat wave hit him in the face.
"Whoo~"
Xu Qingzhou let out a long breath, squinted his eyes at the emerald green ginkgo trees in the distance, and relaxed his brain.
Since the derivation of the formula relating the Reich metric values of the Riemann Zeta function at non-trivial zeros and specific sets of points on the manifold, progress has been almost zero.
For example, f(0) represents the point mapped to the manifold corresponding to the origin s=0 on the complex plane. However, if f(0) is substituted into the calculation formula, it will affect the relative weights between different Reich metrics.
Totally contradictory.
