On the sidelines, Fefferman added: "It should also be possible to use extreme value theory and singularity theory."
After Xu Chuan figured out this key, the two of them had some ideas to solve the problem from other angles.
But on this road, they are latecomers after all.
Compared to Xu Chuan who blazed the trail, there is no doubt that it is easier for latecomers to complete their ideas.
After expressing his thoughts, Fefferman continued: "But what puzzles me is that this method does not seem to be specially constructed for mathematics. It is more like an inference for studying physics."
As he said that, he looked at Xu Chuan and said affirmatively: "Is that so? Xu."
Xu Chuan smiled and said: "Yes, last year, I went with Witten to complete some physical experiments. This function derivation method is part of the mathematical results derived from calculating physical particles."
"It can stably reduce the interval value, construct sharp singularities and swallow-tail singularities, etc., thereby providing analyzability to some differential equations that were originally unanalyzable."
Hearing this, Fefferman showed a true expression.
On the side, Deligne smiled and said: "Young people's thinking is faster than the two old men like us. I communicated with Fefferman twice before, but we still couldn't find a solution to this problem."
"And as soon as you came out, you provided a complete idea."
"After seeing Fefferman, I can solve the isospectral problem and complete the ns equation within three months."
Fefferman glanced at Deligne, always feeling that he was laughing at him, and said: "Please don't bring me when you talk about the old man, I am still very young."
"But I do have to thank Xu this time. It seems that I will try to make my liver explode when I go back."
After a pause, he looked at Xu Chuan and said with a smile: "By the way, you young people use the word 'explosive liver', right?"
