SUMMARY:Yuchen Liu\, K-stability and Moduli of Quartic K3 Surfaces
DESCRIPTION:     Speaker\n\n\nYuchen Liu\nNorthwestern University\n\n\n\n\n\n\nWe show that K-moduli spaces of (P3\, cS) where S is a quartic surface interpolates between the GIT moduli space and the Baily-Borel compactification as c varies in (0\,1). We completely describe the wall crossings of these K-moduli spaces. As a consequence\, we verify Laza-O’Grady’s prediction on the Hassett-Keel-Looijenga program for quartic K3 surfaces. This is based on joint work with K. Ascher and K. DeVleming.

SUMMARY:Yewon Jeong\, Several Types of Dual Defective Cubic Hypersurfaces
DESCRIPTION:     Speaker\n\n\nYewon Jeong\nIBS\, Center for Complex Geometry\n\n\n\n\n\n\nGiven a hypersurface X = V(f) in a complex projective space\, we say X is dual defective if the Gauss map of X\, the restriction of the gradient map of f on X\, has positive dimensional fibers. Especially for cubics\, there is an interesting classification of them. We will study several types of dual defective cubic hypersurfaces and the relation between them.

SUMMARY:Zhi Jiang\, On Syzygies of Abelian Varieties
DESCRIPTION:     Speaker\n\n\nZhi Jiang\nSCMS\, Fudan University\n\n\n\n\n\n\nSyzygies of ample line bundles on abelian varieties have attracted lots of attentions in recent years. People tried to study these geometric objects by different methods\, including Okounkov bodies\, X-methods from MMP\, and generic vanishing theory. We will report some progress on this subject based on the work of Jiang-Pareschi\, Caucci\, and Ito based on cohomological rank functions.

SUMMARY:Feng Shao\, The Bigness of Tangent Bundles of Projective Manifolds
DESCRIPTION:     Speaker\n\n\nFeng Shao\nIBS\, Center for Complex Geometry\n\n\n\n\n\n\nLet X be a Fano manifold. While the properties of the anticanonical divisor –KX and its multiples have been studied by many authors\, the positivity of the tangent bundle TX is much more elusive. In this talk\, we give a complete characterization of the pseudoeffectivity and the bigness of TX for del Pezzo surfaces\, hypersurfaces in the projective space and del Pezzo threefolds.
