Chapter 824: Distant friends

Far on the other side of the earth.
It was late at night on the campus of Princeton University shrouded in darkness, and only a few of the libraries with night study rooms were lit.
Close to the apartment, in the library's activity room, Willa put a stack of papers on the table, opened a page in the paper, and the thin forefinger swept along the line of calculations, and finally stopped in the middle Position, said softly.
"... line 11 on page 27 of the dissertation, there is a problem with the formula."
Compared to three years ago, her size has not changed. The only difference is that the short pony tail, which is always like the tail of a little squirrel, has grown so long that it reaches the arms, which is beautiful and easy to handle Greek princess braid.
If you put on a long skirt with lace, you might even be mistaken for a real princess. But unfortunately, the slender shoulders were just a very ordinary campus dress, which also made her always be mistaken as a high school student to attend the academic summer camp at a certain time ...
"Look ... Oh, God, you are even stricter than my PhD supervisor." Molina rubbed her eyebrows with dark circles, grabbed a pen from the table, and stretched out Sit slowly and straight up.
This feeling of staying up late and bursting into the liver is not good, and it is a burden on both the shoulder and the lumbar spine. Although she was an early student, she couldn't be considered young when she received her doctorate and became a lecturer at Princeton University.
At least, compared to the young girl standing next to her.
Complimented by the partner, Vera smiled a little embarrassedly and said embarrassedly.
"Where, I'm far worse than Ms. Sophie Morel."
Sophie Morel was her mentor while Molina was still studying for a doctorate. The two had cooperated for a long time on the critical line problem conceived by Riemann, but in Sophie Morel After losing the Nobel Prize for 18 years, Sophie gave up the difficult bone of Riemann's conjecture and has transferred to other topics. Now it's pretty good.
And Molina is still struggling with this topic, even if she has changed from a doctoral student to a lecturer at Princeton University, this has not changed.
As for why she got together with Willa, that's a long story.
In short, the two are now fighting for the same goal, the Riemann conjecture, in the same research group.
"No, that's because you're too modest. That coward can't complete the beautiful proof of Kakutani's theorem, and it's absolutely impossible to find such a tricky problem carefully ..." Lina scratched her hair and said a little irritably, "Damn, Odrizko's zero calculation, I should have thought of it earlier."
"Bingo, Oderitzko's zero-point calculation," Vera whispered, wrote two lines of calculations on the paper with a ballpoint pen, and corrected the errors. "The revised algorithm can be launched, 40% The non-trivial zero point is on the critical line ... Congratulations, Ms. Molina, you have discovered a method other than Levinson's algorithm and re-proved the Conrey critical line theorem. "
The last half sentence, she spoke with comfort.
Although, she is not sure whether this can be called comfort.
It took a month to come up with ideas, and another two months to try, but the final result was a conclusion that had been reached in 1990.
The critical line that divides the non-trivial zero point of the z function is still standing on the annoying number of 40%. If anyone can push it forward a little bit, there is hope for the next or the next Fields Prize.
But after so many years, only its challenger has fallen, and no one has taken this evil dragon back a step.
"But it doesn't make sense," Molina sighed. "Maybe ... Chronicle of Mathematics will consider accepting our dissertation."
Vera gave her an encouraging look and said softly.
"I think they should think about it, at least we found another use of Odrizko's zero calculation method."
Unlike other disciplines, mathematical research is not completely results-oriented. Sometimes, although there is no beautiful answer, if the process is good or interesting, it can also be a reason to be published. Especially the "Chronicle of Mathematics", although it is no longer in Princeton's work, it is relatively "loose" for the papers produced by Princeton.
just……
The top four journals, such as the Annual of Mathematics, are more difficult.
"Maybe ..." Molina rubbed her messy long hair. "Maybe we should change our mind. Some time ago I studied Sir Atiya's notes and found his research very interesting."
Willa opened her mouth.
"Molina ..."
Molina, who had dark circles, tilted her head, "What's wrong?"
Willa said seriously: "You really should take a break."
Although it may be a little disrespectful to the late Sir Atiyah, many people had such thoughts before he died, and eventually returned.
"Don't worry about me, I'm fine ..." Molina reached out and touched her forehead. "Maybe you're right, I should rest."
Even when she started studying Sir Atia's thesis, she felt that she must be crazy.
Willa opened her mouth slightly, and finally sat beside her, silent for a moment, and asked.
"Why do you ... always cling to Riemann's conjecture?"
Hearing this question, Molina teased in a rhetorical tone: "Just like why are you attached to that man?"
Vera's face turned slightly red, and after hesitating for a while, she stared at the paper on the table.
"I ... are not as persistent as you say, but he gave me the light when I was most helpless."
Molina: "But it's been many years ago, hasn't it?"
Willa was silent for a moment and nodded.
Indeed, she also knew that it had been many years ago.
She wasn't even sure if Lu Zhou remembered what she looked like.
Although she always remembers what he looks like ...
"Me too ~ EbookFREE.me ~ Morina smiled, her forefinger gently sprayed the empty mug on the table, and continued," Math gave me the same thing. "
Willa looked at her puzzledly.
"But why is Riemann's conjecture?"
"Give me a chance to talk about this again."
Talking, Molina stood up from her chair, but because she was too tired, she stumbled to the side. Fortunately, Vera stood up and supported her, so that she was not tripped.
"Thank you," said Molina, standing with her right hand on the back of the chair, and bent her corners. "If he doesn't want you, you'll marry me."
Vera's face turned red, and she quickly said, "Sorry ... I'm not that."
Molina pouted and smiled.
"I'm just kidding, don't take it seriously."
As she said, she blinked, picked up the paper on the table, hugged her chest, and walked away quickly.
