Title
Algebraic varieties and their symmetry
Abstract
There are many phenomena where algebraic geometry and group theory interplay. Many algebraic varieties have apparent or hidden symmetries such as ADE type of degenerate elliptic curves. In 80's I classified finite groups acting symplectically on a K3 surface, in terms of the Mathieu group M24, a sporadic simple finite group. I will survey an analogous result which I and H. Ohashi recently obtained for Enriques surfaces, another class of algebraic surfaces of Kodaira dimension 0. As a second sample of hidden symmetries, I will discuss a certain connection between Fano threefolds and four Dynkin diagrams of exceptional types.
