SUMMARY:Sheng Meng\, Equivariant Kähler Model for Fujiki's Class
DESCRIPTION:     Speaker\n\n\nSheng Meng\nKIAS\n\n\n\n\n\nLet X be a compact complex manifold in Fujiki’s class C\, i.e.\, admitting a big (1\,1)-class [α]. Consider Aut(X) the group of biholomorphic automorphisms and Aut[α](X) the subgroup of automorphisms preserving the class [α] via pullback. We show that X admits an Aut[α](X)-equivariant Kähler model: there is a bimeromorphic holomorphic map σ : X~ → X from a Kähler manifold X~ such that Aut[α](X) lifts holomorphically via σ.\nThere are several applications. We show that Aut[α](X) is a Lie group with only finitely many components. This generalizes an early result of Fujiki and Lieberman on the Kähler case.We also show that every torsion subgroup of Aut(X) is almost abelian\, and Aut(X) is finite if it is a torsion group.\nThis is a joint work with Jia Jia.

SUMMARY:Sung Rak Choi\, On the Thresholds of Potential Pairs
DESCRIPTION:     Speaker\n\n\nSung Rak Choi\nYonsei Univ.\n\n\n\n\n\nChoi-Park first introduced and develped the notion of potential pairs. The notion was designed to control the singularities of the outcome of the ‘anticanonical’ minimal model program. In this talk\, after reviewing the properties of potnetial klt pairs\, we examine the ACC property of the potential lc thresholds. This talk is based on the joint work in progress with Sungwook Jang.
