     Title:

     Method of branches approximating and its application to the Hessian equation

     Time & Venue:

     2018.7.20 10:00-11:00 N212

     Abstract:

     In this topic, mainly by bifurcation method, we will talk about the existence/nonexistence, uniqueness and multiplicity of of admissible solutions for the k-Hessian equat

     Speaker:

     黄 岸 教授，Brandeis University

     Title:

     Periods, arithmetic, and invariant theory

     Time & Venue:

     2018.7.25 14:15-15:15 N913

     Abstract:

     I shall give an overview of some recent works on relating the arithmetic of hypersurfaces in a suitable ambient variety, with their period integrals. I shall also describe an attempt to use period integrals to study certain classical invariant rings. This is based on recent joint works with Jing-Yue Chen, Bong Lian, Shing-Tung Yau, and Cheng-Long Yu.

     Title:

     On equivariant minimal model program of normal projective varieties admitting polarized endomorphisms

     Time & Venue:

     2018.7.25 15:30-16:30 N913

     Abstract:

     Let X be a normal projective variety admitting a polarized or int-amplified endomorphism f. First, we list up characteristic properties of such an endomorphism. Second, we list up properties of these varieties from the aspects of their singularities, anti-canonical divisors and Kodaira dimensions. Third, we run the equivariant minimal model program relative to not just the single f but also the semigroup of all surjective endomorphisms of X, up to finite-index. Several applications are given.This is a joint work with De-Qi Zhang.
