Largo San Leonardo Murialdo,1 - Pal.C - Aula 211


I'll report on recent joint work with Blum, Halpern-Leistner and Xu where we establish that the automorphism group of a K-polystable Fano variety is reductive.  In this talk, we will discuss the notion of S-completeness and its connection to reductivity.  We will show how the condition of S-completeness for the moduli of log Fanos reduces to the finite generation of a certain ring.
