Automorphisms of Chevalley groups of types $A_l,D_l,E_l$ over local rings without 1/2

Abstract

In the given paper we prove that every automorphism of a Chevalley group of type $A_l$, $D_l$, or $E_l$, $l⩾3$, over a commutative local ring without 1/2 is standard, i. e., it is a composition of ring, inner, central and graph automorphisms.
