At the end of the report meeting, Pang Xuelin, accompanied by Deligne, Peter Sanek and others, had a working meal.

After eating, Pang Xuelin, accompanied by Qi Xin, returned to the hotel, sorted out the board books in the morning into a paper, and uploaded it to arXiv.

By this time, news of his proof of the Polygnac conjecture at the Princeton Conference had spread throughout the academic community.

Although this time period is in the early morning of China, some well-informed academic self-media also forwarded relevant news as soon as possible.

"Pang Shen reappeared in the commotion, and the Princeton report proved the Polygnac conjecture on the spot!"

"The Polygnac conjecture that has plagued the mathematical community for one hundred and seventy years has been proven, and Pang Shen has once again shown the strength of the first person in the mathematical world today!"

"Princeton welcomes the king with thunderous applause!"

"In the next city, Pang Shen will undoubtedly be among the greatest mathematicians in history."

……

And after Pang Xuelin officially released his new paper on arXiv, in less than an hour, major media around the world also forwarded the news.

People's Daily Online: "On the morning of November 2, local time in the United States, Professor Pang Xuelin, a famous mathematician in China, proved the Polygnac conjecture on the spot at the report meeting. At present, whether this proof is valid is still being further verified. ”

The New York Times: "China's genius once again shows amazing talent, and the Princeton Report proves a world-class problem." ”

CNN: "This morning, Professor Pang Xuelin, a well-known Chinese mathematician, proved the Polygnac conjecture at the Princeton Report, which caused a shock in the academic community! ”

The Times: "Pang Xuelin captured the world's top mathematics research center, and Sir Deligne called Pang Xuelin the first person in contemporary mathematics." ”

……

While major media followed up on the reports, Pang Xuelin's phone also kept ringing.

The first person to call was Zhang Yitang.

"Professor Pang, did you really prove the Polygnac conjecture?"

Zhang Yitang's tone still carried a trace of disbelief.

He knew very well that Pang Xuelin officially started to study the twin prime conjecture in the conversation with himself a month ago.

He originally thought that even if Pang Xuelin could really solve the twin prime conjecture, it would take at least two or three years, but who would have thought that Pang Xuelin would complete the agreement with himself in just one month.

Moreover, he overcame the generalized conjecture of the twin prime conjecture - the Polygnac conjecture.

This conjecture is much more difficult than the twin prime conjecture.

Pang Xuelin smiled faintly: "I just uploaded the proof paper on arXiv, I should be eighty or ninety percent sure!" ”

"Good! Good! Good! ”

Zhang Yitang couldn't help but shout three times in a row, and then said: "Professor Pang, I'll read your paper first, and I won't talk much." ”

After that, Zhang Yitang hung up the phone directly.

Although he knew very well in his heart that Pang Xuelin was eighty or ninety percent sure of what he said, it was almost 100 percent.

But he will always feel relieved after reading the paper.

After Zhang Yitang, Liu Tingbo, Zhang Deye and even Yau Chengtong and others also called one after another.

They were all woken up on the phone by a friend in the math community while they were sleeping, and they learned the shocking news.

At the same time, some reporters who were familiar with Pang Xuelin called, hoping to do a brief interview with Pang Xuelin about this incident, but Pang Xuelin politely refused.

For him, he will not be interviewed until at least the process of proving the Polygnac conjecture has been fully accepted by the mathematical community.

By the time Pang Xuelin finished dealing with all kinds of calls, it was already evening.

Pang Xuelin sat at the desk, looked at the time, and said to Qi Xin, who had been by his side: "Xiao Xin, you prepare, and go to the dinner at Princeton with me later." ”

Deligne had previously informed Pang that Princeton University and the Institute for Advanced Study at Princeton would hold a grand dinner for him, both to welcome him and to celebrate the morning presentation.

Pang Xuelin couldn't shirk it, so he had to agree.

Qi Xin walked behind Pang Xuelin, reached out and hugged Pang Xuelin's head, and whispered in his ear: "I won't go, there may be reporters at the dinner later, and it is not suitable for me to show up now." I'm in my room, waiting for you to come back......"

When he said the last sentence, Qi Xin's pretty face flushed with a faint flush.

Pang Xuelin was slightly moved in his heart, he knew that Qi Xin didn't want to make it difficult for him.

He pulled Qi Xin into his arms, looked at the girl's delicate and infinitely pretty face, and silently lowered his head.

It took a long time for the two to separate out of breath.

That evening, Pang Xuelin received a warm welcome from many scholars.

This dinner brought not only many well-known figures in the field of mathematics, but also many scholars from other disciplines in the field of Advanced Study in Princeton.

For example, the thin and obscene-looking little old man in front of him is tirelessly selling his ideas to Pang Xuelin.

"Professor Pang, you know what? It's really incredible, according to your paper on the preparation of high-purity single-walled carbon nanotubes published in Nature in the first half of the year, I found that this method can be used in the preparation of graphene as long as it is improved, and it is expected to prepare that kind of super-large-scale single-layer graphene ......"

"Are you ......?"

"Kirton Walker, professor of chemical engineering at Princeton."

Pang Xuelin smiled faintly and said: "Professor Walker, the idea you said is indeed feasible, at present, my experimental group at Jiangcheng University has completed the laboratory preparation of this graphene, and if the paper is concerned, I think you should be able to see it in Nature within a month." ”

Walker was slightly stunned and said, "Professor Pang, do you know what the biggest use of this material is?" ”

"What's the biggest use?"

Walker said: "Lithium-air batteries! You should know that while lithium-air batteries are promising, they have a fatal flaw in their own right, as lithium hydroxide (LiOH), a solid reaction product, builds up at the positive electrode, blocking the contact between the electrolyte and the air, causing the discharge to stop. We can take advantage of the tunneling effect of the carbon atom ring of the graphene material and use an organic electrolyte on the negative side and an aqueous electrolyte on the positive side. A solid electrolyte membrane made of graphene material is set between the two electrolytes to separate them. This prevents the electrolyte from mixing and promotes the reaction of the battery. ”

Pang Xuelin's eyes narrowed slightly, looked at Walker and said, "Professor Walker, is it convenient to give me your contact information?" I'd love to talk to you tomorrow. ”
