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

In the given paper, we prove that every automorphism of a Chevalley group of type $A_l$, $D_l$, or $E_l$, $l\geq3$, over a commutative local ring without 1/2 is standard, i.e., it is a composition of ring, inner, central, and graph automorphisms.
