Scholar’s Advanced Technological System

“Of course you can…”

Lu Zhou made a gesture to invite Professor Fefferman to the whiteboard.

Professor Fefferman picked up a marker and stared at the whiteboard for a while. He then started to write.

The lecture was technically over, but not a single person left the lecture hall.

Everyone, including Lu Zhou, stared at the whiteboard.

Lu Zhou looked at what Professor Fefferman was writing, and his eyes gradually lit up.

Amazing…

This was an interesting part of mathematics.

A method that was unfeasible would never work, no matter how many times one tried.

But once one embarked on a method that might work, one could feel the victory ahead.

Although Fefferman hadn’t finished writing, Lu Zhou was 90% certain that his method was correct.

As expected, this big name didn’t let him down.

Professor Fefferman swiftly filled in the rest of the calculation steps and wrote one final line.

[Pμi:= μi – (Δ^-1)·δi·δj·μj]

There was a commotion in the classroom. Although this content was too difficult for undergraduate students, this was still Princeton.

They couldn’t think of the method, but they could understand it.

Obviously, their comprehension speed was slower than Lu Zhou’s, but just like Lu Zhou, they saw the ingenuity of Professor Fefferman’s workings.

Professor Fefferman placed down the marker and carefully read his calculations from beginning to the end. After that, he smiled and said, “This question isn’t easy… A bit too difficult for undergraduate students.”

Lu Zhou coughed and said, “Hence, it is supposed to be a thought-invoking question.”

Lu Zhou only planned to lecture the students. He wouldn’t have written his research problem on the whiteboard if there weren’t so many students interested.

Lu Zhou definitely didn’t expect this big name to sit at the back of the lecture hall.

Professor Fefferman placed his attention back to the contents on the whiteboard and rubbed his chin as he spoke in a thoughtful manner.

“(Δ^-1)·δi·δj is defined as the Fourier multiplier of ξiξj/|ξ|2… But what I want to know is that even if you have derivation equation of Pμi, what is the point? I can’t seem to grasp it… Can you explain it to me?”

“Of course,” Lu Zhou smiled and said, “but I’ll need a new whiteboard.”

“Princeton has plenty of whiteboards, I’ll find one for you.”

Professor Fefferman left the lecture hall and came back with a whiteboard.

Lu Zhou erased the writing on the new whiteboard and picked up the marker. He then began to explain while writing.

“If we get Pμi: = μi-(Δ^-1)·δi·δj·μj, we can find the non-diverging property of μ for conventional integration…”

Lu Zhou’s research was only up to the “Pμi:=?” step. Therefore, he was deriving equations on the spot.

This sounded difficult.

But actually, it was very easy.

After all, all he needed to do was to use the new conclusion to continue his train of thought.

However…
