Sung-Yeon Kim, Proper holomorphic maps between bounded symmetric domains
B236-1 IBS, Korea, Republic ofSpeaker Sung-Yeon Kim IBS CCG In this talk, we study the rigidity of proper holomorphic maps f: Ω→Ω' between irreducible bounded symmetric domains Ω and Ω'. First, we …
Ngoc Cuong Nguyen, Equidistribution of Fekete points on projective manifolds
B236-1 IBS, Korea, Republic ofSpeaker Ngoc Cuong Nguyen KAIST We survey recent developments on the speed of convergence of Fekete points on projective manifolds where the equidistribution was proved by Berman and …
Lorenzo Barban, General results on C*-actions on projective varieties
B236-1 IBS, Korea, Republic ofSpeaker Lorenzo Barban IBS CCG In this lecture series we aim to describe the rich relation between C*-actions on complex normal projetive varieties and the birational maps among …
Lorenzo Barban, Geometric Invariant Theory for C*-actions
B236-1 IBS, Korea, Republic ofSpeaker Lorenzo Barban IBS CCG In this second talk, which is the technical core of the lecture series, we describe several tools to study C*-actions on projective varieties, …
Lorenzo Barban, Geometric realization of birational maps among Mori dream spaces
B236-1 IBS, Korea, Republic ofSpeaker Lorenzo Barban IBS CCG Given a birational map ϕ among normal projective varieties, a geometric realization of ϕ is a normal projective C*-variety such that the birational …

Mihai Paun, Hermitian-Einstein metrics for stable coherent sheaves and Bogomolov-Gieseker inequality(Lecture III)
B236-1 IBS, Korea, Republic ofSpeaker Mihai Paun U. Bayreuth I will survey the main results obtained in the articles arXiv:2501.18088 and arXiv:2405.10003. There will be no "serious" proofs, I will nevertheless try …
Jinhyung Park, Effective gonality theorem on weight-one syzygies of algebraic curves
B236-1 IBS, Korea, Republic ofSpeaker Jinhyung Park KAIST In 1986, Green-Lazarsfeld raised the gonality conjecture asserting that the gonality gon(C) of a smooth projective curve C of genus g can be read …
