Reductivity of the automorphism group of K-polystable Fano varieties

Jarod Alper, Harold Blum, Daniel Halpern-Leistner +1

We prove that K-polystable log Fano pairs have reductive automorphism groups. In fact, we deduce this statement by establishing more general results concerning the S-completeness a…

Jarod Alper, Daniel Halpern-Leistner, Jochen Heinloth

We provide a short and self-contained argument for the existence of Cartan-Iwahori-Matsumoto decompositions for reductive groups.
