Unique and One of a Kind
Shen Qi was inspecting the examination hall. An hour had passed, and he strolled back behind the girl with long, straight black hair.
This girl's hairstyle is very similar to Ou Ye's. She is looking down at her homework, her long hair falling down to cover her side profile.
Looking at her from behind, this girl's appearance does bear a striking resemblance to Ou Ye.
Shen Qi shook his head. There are many girls with long, straight black hair, but there is only one Ou Ye, and the Calculation Ji is one of a kind.
An hour passed, and the freshman girl had completed three fill-in-the-blank questions; she was now working on the first proof question.
The first three fill-in-the-blank questions were set by Sun Erxiong, and the last two were set by Shen Qi. The first-year female student couldn't solve them.
A freshman girl suddenly turned around and found someone standing behind her. She exclaimed in surprise, "What are you doing here?!"
"No, please focus on answering the questions." Shen Qi gently tapped the girl's desk and calmly walked away.
This girl's appearance is similar to that of Ou Ye, but the moment she opens her mouth, the style changes drastically.
After the Advanced Algebra exam, Shen Qi immediately sent Ou Ye a WeChat message: "Happy New Year."
Ou Ye replied instantly, "There's still a month until the New Year."
Shen Qi: "Wishing you a Happy New Year in advance! Good health and happiness for your family."
Ou Ye sent a laughing emoji with her hands covering her mouth, "Has the straight man turned into a warm man?"
"I miss you." Shen Qi didn't know why he typed those three words; it seemed like an unconscious action.
Two minutes passed, and Ou Ye did not reply.
Shen Qi leaned against the wall outside the classroom and smiled. He had indeed begun to miss Ou Ye.
When she's not around, it really does feel a little strange.
Another minute passed, Ou Ye finally replied, "I want to go back to school."
"Will you be able to come back when school starts next semester?" Shen Qi asked.
Ou Ye: "Yes, definitely! I will take my medicine diligently, treat myself optimistically, and come back soon!"
Shen Qi: "I'll wait for you."
After sending the WeChat message, Shen Qi went to the SOS Project Office, turned on Ou Ye's computer, and wanted to give Ou Ye another gift, a gift called "Proof of the Proof of Diophantine Equation Wash Conjecture".
American mathematician Wash once proposed a conjecture: if a and b are positive integers, then the equation aX^4-bY^2=1 has at most two sets of positive integer solutions (X, Y).
Whether it's Goldbach or Fermat, people who play with number theory love to make conjectures.
What's even more infuriating is that Goldbach and Fermat were amateur mathematicians.
Wash was a professional mathematician, and the proof of his Diophantine equation conjecture was less difficult than that of Goldbach Conjecture and a series of Fermat's conjectures.
Six months ago, Shen Qi happened to browse through an English mathematics journal and found an interesting paper. The author of the paper was a German female PhD.
A female PhD student in the Mathematics Department at the University of Bonn, Germany, used the p-adic method in her Doctoral Thesis, employing highly complex techniques, to derive the Diophantine equation of the form aX^2 - bY^4 = c, c ∈ {1, 2, ±4}.
The exact upper bound of the number of solutions.
The research findings of the German female PhD student are very close to proving the Wash Conjecture.
Then Shen Qi went for a run and had an idea.
Combining the findings of the German female PhD student with the Thue-Siegel method, can an effective algebraic approximation be made to completely prove the Wash Conjecture?
Shen Qi shared this mathematical inspiration with Ou Ye, although he understood number theory, he didn't have that much energy.
The paper, "On the Proof of Diophantine Equation Wash Conjecture," was started by Shen Qi, with Ou Ye completing 50% of the drafting. At the same time, Ou Ye was also working on the SOS project.
Then Ou Ye fell ill and has been recuperating at home for two months.
Shen Qi decided to finish the remaining 50% of the work as soon as possible, and he would co-author this paper on number theory with Ou Ye.
The days of writing the thesis passed quickly; half a month went by in the blink of an eye, and progress was going smoothly.
During this period, Shen Qi took several physics exams and got full marks on all of them.
"Why are you studying number theory? What happened to the Mathematical Physics you were supposed to be doing?" Sun Erxiong walked into the SOS Office.
"For someone who deserves it." Shen Qi saved the LaTeX document. His work before winter break was over. He was going home for the Chinese New Year tomorrow.
"Look at you, all for love, huh?" Sun Erxiong was indeed a seasoned pro; his eyes were sharp.
"What is love? Can you eat it?" Shen Qi asked with a smile.
"Keep pretending, keep pretending." Sun Erxiong stopped dwelling on the topic of young people's love. He slammed two sample copies of the * Mathematical Herald * on the table, his face beaming. "Mission accomplished! Tonight, let's go out for a drink to celebrate!"
"Published?" Shen Qi flipped through the journal; the SOS Project paper, "Non-Constant Equilibrium Solutions of the Bipolar Non-Isentropic Euler-Poisson Equation," had been published.
"It was published as expected, so fast!" Shen Qi was overjoyed.
System notification: "New achievement! The host has published one SCI paper and completed a National Natural Science Foundation project. The basic reward is 50,000 Academic Excellence Points, multiplied by the Mathematics Talent Coefficient of 2.0, resulting in a final reward of 100,000 Academic Excellence Points. Balance: 187,549."
Please confirm to accumulate academic points.
"The progress of the achievement task 'Diligent Paper Writing Award' is 8/10. Please continue your efforts."
"Awesome!" Shen Qi roared.
"It's a pity Ou Ye isn't here; it'll just be the two of us drinking tonight." Sun Erxiong with some regret, "You and Ou Ye are the most talented and hardworking students I've ever taught. Shen Qi, Ou Ye is a girl after all; you need to take the initiative, you know?"
"Why has everyone become an expert on relationships? Is love so cheap?" Shen Qi picked up two copies of the * Mathematical Herald * and said before leaving the office, "See you tonight, Professor Sun. Anyway, thank you for your guidance."
Before dinner, Shen Qi went to the school's express delivery point. He wanted to send a sample copy of the "Mathematical Herald" to Ou Ye that she could see the research results before the Spring Festival. These were the research results she had devoted herself to and which had caused her to fall ill.
"What is your exact home address? Send it to my phone." Shen Qi called Ou Ye directly.
"W-what?" Ou Ye's heart was pounding, which could be felt from her surprised and delighted tone.
"I'm going to your house to wish you a Happy New Year," Shen Qi teased Ou Ye.
"You really want to come to my house? But... but I'm not completely ready yet..." Ou Ye's voice trailed off.
"So, tell me if you welcome me or not," Shen Qi said, trying not to laugh.
"Of course... When did you arrive?" Ou Ye seemed to have mustered her courage.
"Second year of junior high, next year's second year of junior high, I won't be going to your house this year." Shen Qi couldn't tease Ou Ye anymore, or it would become true.
"How annoying!" Ou Ye scolded playfully.
Shen Qi got back to the point. "Stop joking. The SOS research paper has been published. I'll send you a sample copy by express mail. Send me your address right away."
"Ou Ye, who are you talking to? Who's coming to our house?" Just then, Shen Qi heard a man's voice on the phone, a very loud one, like Old Ou.
"I'll send it to you right away, bye-bye." Ou Ye hung up the phone in a hurry.
Soon, Shen Qi received Ou Ye's message. He sent the package to the address in the message, and then went to a restaurant outside the school to drink celebratory wine with Sun Erxiong.
