After the number theory lecture, Lu Zhou went to his complex functions lecture. After all, he was still enrolled in this class, plus his roommates were there.
During the lecture, when the teacher saw him sitting there, he asked him to teach instead.
Lu Zhou started talking about the complex plane and the Riemann sphere. Even though he was not very skilled at public speaking, it gradually became smoother.
However, he obviously ignored the abilities of the listeners.
While he was lecturing on stage, the students who were listening were all muddled.
Only a few people could keep up with his stage. For example, Luo Rundong. Others, like Liu Rui, could barely keep up.
"… the transformation function between ζ-coordinates and ξ-coordinates can be obtained by compounding one of the maps with the inverse of the other and can be obtained by a transformation. The unit sphere and the Riemann sphere are different from the same embryo."
