SUMMARY:Hoseob Seo\, On Singularities of Toric Plurisubharmonic Funcitons
DESCRIPTION:     Speaker\n\n\nHoseob Seo\nResearch Institute of Mathematics\, Seoul National University\n\n\n\n\n\n\nIn this talk\, we discuss recent progresses on singularities of toric plurisubharmonic functions. First\, we review the notion of Newton convex bodies of toric plurisubharmonic functions on a polydisk D(0\,r) ⊂ Cn. As an application\, we show that the cluster points of jumping numbers of J(φ)0 are not accumulated and give a precise characterization of the set of those cluster points. These generalize a recent result of Kim and Seo from n = 2. \nOn the other hand\, we extends a result by Guan\, which proved when toric plurisubharmonic functions of the form log(∑ |z|ai) have a decreasing equisingular approximation with analytic singularities. We give a criterion for the existence of a decreasing equisingular toric approximation with analytic singularities for a given toric plurisubharmonic function. This is a joint work with Jongbong An.

SUMMARY:Dano Kim\, Canonical Bundle Formula and Degenerating Families of Volume Forms
DESCRIPTION:     Speaker\n\n\nDano Kim\nDepartment of Mathematical Sciences\, Seoul National University\n\n\n\n\n\n\nWe will talk about a metric version of Kawamata’s canonical bundle formula for log Calabi-Yau fibrations: the L2 metric carries singularity described by the discriminant divisor and the moduli part line bundle has a singular hermitian metric with vanishing Lelong numbers. This answers a folklore conjecture arising from work of Kawamata and Tsuji and a question of Eriksson\, Freixas i Montplet and Mourougane. It has immediate applications to L2 extension theorems which was our starting point.

SUMMARY:Baohua Fu\, Normalized Tangent Bundle\, Pseudoeffective Cone and Varieties with Small Codegree
DESCRIPTION:     Speaker\n\n\nBaohua Fu\nChinese Academy of Science\n\n\n\n\n\n\nWe propose a conjectural list of Fano manifolds of Picard number one whose normalized tangent bundle is pseudoeffective and we prove it in various situations by relating it to the complete divisibility conjecture of Russo and Zak on varieties with small codegrees. The pseudoeffective cone of the projectivized tangent bundle of a rational homogeneous space of Picard number one is explicitly determined by studying the total dual VMRT and the geometry of stratified Mukai flops. This is a joint work with Jie LIU.
