Seungjae Lee, Cohomological Isomorphism of Symmetric Power of Cotangent Bundle of Ball Quotient and its Toroidal Compactification

B236-1 IBS, Korea, Republic of

    Speaker Seungjae Lee IBS CCG In this talk, we investigate the L2-Dolbeault cohomology of the symmetric power of cotangent bundles of ball quotients with finite volume, as well as their toroidal compactification. As a result, we establish a version of L2-Hodge decompostion for complex hyperbolic space forms with finite volume, under some mild …

Andreas Höring, Projective Manifolds with Pseudoeffective (Co)tangent Bundle, I, II

B236-1 IBS, Korea, Republic of

    Speaker Andreas Höring University of Nice Symmetric holomorphic forms on projective manifolds have been studied from various angles in the last ten years : Brotbek-Darondeau and independently Song-Yan Xie have shown that complete intersections of sufficiently high degree and codimension have an ample cotangent bundle, so many symmetric forms. Vice versa Campana and …

Grzegorz Kapustka, Projective Models of Nikulin Orbifolds

B236-1 IBS, Korea, Republic of

    Speaker Grzegorz Kapustka Jagiellonian University We describe a locally complete family of projective irreducible holomorphic symplectic orbifolds as double covers of special complete intersections (3, 4) in P6. This is a joint work with C. Camere, A. Garbagnati and M. Kapustka.

Youngju Kim, Tubular Neighborhoods in Complex Hyperbolic Manifolds

B236-1 IBS, Korea, Republic of

    Speaker Youngju Kim Konkuk University The collar lemma says that a closed geodesic in a real hyperbolic 2-manifold has an embedded tubular neighborhood whose width only depends on the length of the geodesic. The width of the collar does not depend on the underlying hyperbolic 2-manifold. On the other hand, a totally geodesic …

Claudia Stadlmayr, Which Rational Double Points Occur on del Pezzo Surfaces?

B236-1 IBS, Korea, Republic of

    Speaker Claudia Stadlmayr Technische Universität München Canonical surface singularities, also called rational double points (RDPs), can be classified according to their dual resolution graphs, which are Dynkin diagrams of types A, D, and E. Whereas in characteristic different from 2, 3, and 5, rational double points are "taut", that is, they are uniquely …
