Speaker：Zhan Li (Southern University of Science and Technology)

Abstract

In this talk, I will explain the relationship between the Morrison-Kawamata cone conjecture for Calabi-Yau fiber spaces and the existence of Shokurov polytopes. For K3 fibrations, this enables us to establish the existence of (weak) fundamental domains for movable cones. This is joint work with Hang Zhao.

Calabi-Yau threefolds with c_2-contractions-revisited
AbstractThe second Chern class $c_2$ plays a special role in studying Calabi-Yau threefolds. Among other things, we discuss about KSC (Kawaguchi-Silverman's Conjecture) and the finiteness problem of real forms of Calabi-Yau threefolds with $c_2$-contractions. Though nothing appears in the title and main statements, our arguments use dynamical degrees due to Dinh-Sibony and current work on slow ...
