Chapter 397: Let You Experience the Enthusiasm of Boston Women

Inside the office, Xu Qingzhou sat down and greeted the white-haired old man: "Professor Roberts."

Professor Roberts, like Holn, looked exhausted. He couldn't help but secretly sigh that these two were worthy of being master and apprentice; they both looked like they didn't have much spirit... It was also fortunate that there was School Beauty Song.

Otherwise...

He himself might also become one of them, wearing big dark circles every day, with hair gradually thinning.

"Welcome to the Massachusetts Institute of Technology, please sit..." Professor Roberts moved the manuscript on the chair, signaling that Xu Qingzhou could sit down.

"Try my hand-drip coffee." Holn had already poured coffee for Xu Qingzhou and Professor Roberts.

"Thank you." Xu Qingzhou thanked him.

"I guarantee you, my coffee-making level is definitely more professional than doing mathematical calculations."

Holn said happily.

Professor Roberts piled the manuscripts at his feet, took a sip of coffee, and smiled. "Holn's coffee-making technique is definitely number one at MIT. Many professors come over to ask for a cup of coffee during their breaks."

"Very delicious."

Xu Qingzhou praised after tasting it; it had to be said, the taste was indeed very good.

"It's a pity, if I didn't study mathematics, I would definitely have become an excellent barista." Holn said with pride mixed in his sigh.

On this side, Professor Roberts put down his coffee and talked about business: "It's been a week since our last discussion. Do you still plan to engage in research on the Riemann Hypothesis?"

"Mmm, life, after all, always requires doing some challenging work." Xu Qingzhou nodded and said while drinking.

"I also studied the Riemann Hypothesis when I was young, but..."

Professor Roberts paused and said, "We are planning to do a project on linear algebra. Specifically, it's large-scale matrix calculation and its application in recommendation systems. If you are willing to come over, I would be very welcome."

"Of course, if you choose the Riemann Hypothesis, or do other projects alone, that's also fine."

Xu Qingzhou had learned about this project.

During this period, short video platforms were on the rise. Designing algorithms for efficiently processing large-scale sparse matrices, especially in recommendation systems, and how to use these algorithms to accelerate similarity calculations between users and items to improve recommendation accuracy and real-time performance, was indeed a hot topic for the next few years.

"Thank you for the professor's invitation."

Xu Qingzhou said with a smile, "I'll still try the Riemann Hypothesis. You know, this thing seems to have a different kind of magic for those who study mathematics."

Professor Roberts nodded slightly, understanding the young man's mind. Not only him, but even his mentor had tried it, but in the end, there were no results.

He said, "It's a pity, I might not be able to give you too many suggestions on this topic, but if you are willing, you are welcome to come and discuss it with me."

"Xu, you are very talented. I don't have too many rigid requirements for your graduation, nor will I interfere with your project, but for your graduation thesis, I hope you can produce some good results, at least reaching the standard of *Inventiones Mathematicae*. I believe you can easily do this."

Xu Qingzhou nodded; it was indeed not difficult.

Professor Roberts said with a smile, "However, although I don't require you to participate in my project, some work might need you to do. Don't worry, it won't take up too much of your energy."

"What work?"

Xu Qingzhou was not surprised by this; it was a common thing for doctoral students to share the work of their mentors.

Before Professor Roberts could speak, Holn laughed: "Teaching assistant. My previous job, occasionally going to give lectures to undergraduates. This should be very easy for you."

"Analytic Number Theory." Professor Roberts added on the side.

"No problem."

Xu Qingzhou agreed with a smile. Holn joked, "Giving lectures often helps expand your own thinking. Xu, maybe you'll suddenly solve the Riemann Hypothesis while you're lecturing."

"I hope my luck can really be that good."

Next, everyone didn't waste time, and Holn accompanied Xu Qingzhou to complete the enrollment procedures.

Unlike domestic universities, the campuses of schools here are integrated with the city and community, without clear dividing lines. Walking on the road, one can indeed feel a strong academic atmosphere.

The two crossed two streets and found the reporting address written in the email: Room E18-172.

Because Jingda had already docked, the MIT card number and Athena account were already prepared, so the procedures were very simple: signing a name, confirming whether to stay in accommodation, and so on.

By the way, there was also the bank card number for the scholarship.

He, like School Beauty Song, both had full scholarships.

About 10 minutes later, the enrollment procedures were done.

"Xu, if I didn't have to fly to damn New York in a moment, I would definitely take you for a good drink."

Holn laughed, "Let you experience the enthusiasm of Boston women."

(Author's note: Read every word of the content!)

"Drinking is fine, but women are not needed; I have a girlfriend."

Xu Qingzhou didn't want to be beaten up by School Beauty Song.

"That's too bad... But in any case, we must have a drink after I come back."

"Definitely." Xu Qingzhou nodded with a smile.

When the two returned, Professor Roberts handed Xu Qingzhou a pile of manuscripts, saying they were his research manuscripts on the Riemann Hypothesis, hoping they would be useful to Xu Qingzhou.

Xu Qingzhou expressed his gratitude.

Professor Roberts and Holn were in a hurry to catch their flight and left in a rush, so Xu Qingzhou hugged the manuscripts and returned to the hotel.

Hotel room.

Er Miao was lying on the windowsill, drooping its head. It was much more miserable than Xu Qingzhou and the others; it had spent more than 20 hours on a plane these few days and could only stay in a narrow cat bag.

Seeing Xu Qingzhou return, Er Miao meowed and walked over to rub against his thigh.

"Wait a moment, I'll feed you right away."

Xu Qingzhou put down the manuscripts. This stupid cat was probably hungry. Previously, there was an automatic feeder, but now Er Miao's belongings were all left at Yandong Garden, and they needed to be re-purchased after settling down.

He rummaged through his schoolbag to find a plastic bowl, poured cat food for Er Miao, and then sat down in the chair, intending to read Professor Roberts' manuscripts first.

During the few days on the road, he had already finished using algebraic methods to continue analyzing the Riemann Hypothesis. Next, he planned to analyze the method of continuation, expanding the definition domain of the Z-function from real numbers to the complex number range.

In general, it was to first understand what the Riemann Hypothesis was.

Er Miao was burying its head in eating, making *ka-ka* sounds. Xu Qingzhou remembered that it was time for lunch. Song Yao was eating at school today, and he was too lazy to go down, so he directly asked the waiter to send up a portion of spaghetti, while he opened the manuscripts.

Finishing it in a few bites, he continued to do serious work.

The first stack, the application of the Riemann Hypothesis in integer distribution, used analytic methods to study the problem of integer distribution with a fixed number of prime factors, applying the Riemann Hypothesis to provide an estimate of the error term in its mean distribution.

In the manuscript, it also studied the distribution of integers with a fixed number of prime factors.
