Chapter 722: Professor Xu seems to be coming in our direction!

Xu Qingzhou didn't read Mochizuki's paper carefully but first took out his phone to check relevant news.

It would be a lie to say he wasn't surprised; he had just refused to be an external reviewer last month, and it was published in the journal this month.

Sure enough, the mathematical world was quite lively.

IUT theory, introduced earlier, is the Inter-universal Teichmüller theory used by Shinichi Mochizuki to prove the ABC conjecture.

The reason IUT theory attracted everyone's attention is that from 2012 to 2020, it underwent review for a full 8 years, which can be considered to have set a record for the time taken for peer review.

Regarding Shinichi Mochizuki's IUT theory, Japanese mathematicians certainly praised it to the skies, calling it "solving an important problem." Masaki Kashiwara evaluated it as "having a major impact," and his proof attempt was a "lonely mathematical revolution."

But the opposition was also very clear; most mathematicians insisted that the "proof has not been verified." Scholze reiterated on YouTube that "ABC is still a conjecture." Terence Tao also believed that the paper had serious logical loopholes, and the reasoning for "Corollary 3.12" in the third paper from 8 years ago still hadn't been corrected.

Even more interesting is that Mochizuki himself is the editor-in-chief of *PRIMS*.

Clearly, *Inventiones Mathematicae* also refused the publication of Mochizuki's paper, or rather, after he refused to serve as a reviewer, no peers were willing to spend the energy to study a "new" theory.

Mochizuki claimed to have avoided suspicion and had a clear conscience, but he still couldn't get rid of the suspicion of being both the author and the reviewer.

Xu Qingzhou curiously found the paper and took a look, finding that the logic was indeed quite unique, even more mysterious than his supersymmetric function theory.

After all, his theory at least had traces to follow.

"You, go down and calculate this part first." Gu Zhizhong waved his hand, signaling that Zou Xizhu beside him could leave.

With Xu Qingzhou here, this little girl's mind had long since drifted away.

Her heart was in chaos; how could she still listen to the lecture?

He also understood; Xu Qingzhou, this kid, was young, and he had won all the big awards in the world—the Fields Medal, the Wolf Prize, the Nobel Prize.

In the eyes of these young people, he was completely an idol.

Alright, not to mention young people, even the older generation of scientists often sighed and admired this twenty-four-year-old young man in front of them.

"Oh, good."

Zou Xizhu nodded obediently, knowing that Gu Zhizhong and Xu Qingzhou had something to say, and left with her notebook. "Goodbye, Professor Gu; goodbye, Professor Xu."

Seeing Xu Qingzhou reading the paper, Gu Zhizhong asked with a smile: "How is it? Any interest in researching it?"

"Forget it, no time."

Xu Qingzhou shook his head: "My supersymmetric Z-function theory is enough to give me a headache; I won't add to my own trouble by researching another new theory."

"Yes, I also just took a casual look. Although many people criticize him, it cannot be denied that Mochizuki's mathematical ability is irrefutable; even reading this paper is very difficult."

Gu Zhizhong sighed and said.

Xu Qingzhou didn't commit himself. The difficulty of Mochizuki's IUT theory was indeed not small. Before this, it was claimed that only a dozen people in the world could study the paper, and it was precisely because the proof was complex that it hindered independent verification.

"Your complexion isn't very good; you've been busy to death during this period, right?"

"A bit, developing a new technology."

After chatting nonsense with Gu Zhizhong for ten minutes, Xu Qingzhou filled his teacup before leaving, said goodbye, and prepared to go to class.

Two months had passed, and the people coming to take photos and check in had finally decreased, but the classroom was still packed.

6:30 PM.

Sunset is early in winter; now the sun had fallen below the horizon at four or five in the afternoon.

When Xu Qingzhou walked into the cafeteria, the twilight was already quite thick.

Although it was already a bit late, there were still quite a lot of people in the cafeteria.

Besides those eating, there were stacks of books in front of them, studying seriously. Many students were too lazy to go to the library and directly used the cafeteria as a study room.

By the window, three girls had just finished getting their food and sat down.

"Oh my, we should have gone outside to eat. I have an older sister who opened a Cantonese restaurant in the Changchun Yuan area; the taste is quite good." ===== CHAPTER 723 =====
