Automorphisms of Chevalley groups of type $F_4$ over local rings with 1/2

E. I. Bunina

Published 2009-07-31Version 1

In the paper we prove that every automorphism of a Chevalley group of type $F_4$ over a commutative local ring with~1/2 is standard, i. e., it is a composition of ring and inner automorphisms.
