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 ...
AbstractIn 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.Speaker李展, 南方科技大学助理教授,研究方向为代数几何,特别是双有理几何。2014年博...
