Calabi-Yau manifolds in wider sense
Current research
I am studying Calabi-Yau manifolds in wider sense, mostly K3 surfaces,Calabi-Yau manifolds in the strict sense and compact hyperkaeher manifolds. Currently, I am mainy studying the existence problem of primitive automorphisms, the Kawamata-Morrison cone conjecture, and the(non-)liftability problem of automorphisms of K3 surfaces from positive characteristic to characteristic zero, from both birational geometrical view and complex dynamical view.
