Changho Han, Compact Moduli of Lattice Polarized K3 Surfaces with Nonsymplectic Cyclic Action of Order 3
on-lineSpeaker Changho Han University of Georgia Observe that any construction of "meaningful" compactification of moduli spaces of objects involve enlarging the class of objects in consideration. For example, …
Yoon-Joo Kim, The Dual Lagrangian Fibration of Compact Hyper-Kähler Manifolds
on-lineSpeaker Yoon-Joo Kim Stony Brook University A compact hyper-Kähler manifold is a higher dimensional generalization of a K3 surface. An elliptic fibration of a K3 surface correspondingly generalizes …
Yuchen Liu, K-stability and Moduli of Quartic K3 Surfaces
on-lineSpeaker Yuchen Liu Northwestern University We show that K-moduli spaces of (P3, cS) where S is a quartic surface interpolates between the GIT moduli space and the Baily-Borel …
Yewon Jeong, Several Types of Dual Defective Cubic Hypersurfaces
TBASpeaker Yewon Jeong IBS, Center for Complex Geometry Given a hypersurface X = V(f) in a complex projective space, we say X is dual defective if the Gauss …
Zhi Jiang, On Syzygies of Abelian Varieties
on-lineSpeaker Zhi Jiang SCMS, Fudan University Syzygies of ample line bundles on abelian varieties have attracted lots of attentions in recent years. People tried to study these geometric …
Feng Shao, The Bigness of Tangent Bundles of Projective Manifolds
TBASpeaker Feng Shao IBS, Center for Complex Geometry Let X be a Fano manifold. While the properties of the anticanonical divisor -KX and its multiples have been studied …
Jie Liu, Bigness of Tangent Bundles of Fano Manifolds with Zero Dimensional VMRT
TBASpeaker Jie Liu Institute of Mathematics, AMSS, CAS It is expected that the bigness of tangent bundle is a quite restrictive property for Fano manifolds, especially for those …
Jihun Yum, Limits of Bergman kernels on a Tower of Coverings of Compact Kähler Manifolds
B266 IBS, Korea, Republic ofSpeaker Jihun Yum IBS, Center for Complex Geometry The Bergman kernel BX, which is by the definition the reproducing kernel of the space of L2 holomorphic n-forms on …
