Chuyu Zhou, Lecture 1: Constructible Properties of Various Domains for a Family of Couples
B236-1 IBS, Korea, Republic ofSpeaker Chuyu Zhou Yonsei University In this lecture, I will recall some basic knowledge on K-stability and some background on wall crossing in proportional setting. Then we plan …
Chuyu Zhou, Lecture 2: Non-linear Wall Crossing Theory
B236-1 IBS, Korea, Republic ofSpeaker Chuyu Zhou Yonsei University In this lecture, we will talk about two properties of K-semistable domains in non-proportional setting. One is the finiteness criterion, which states that …
