Automorphisms of a Chevalley group of type G2 over a commutative ring R with 1/3 generated by the all invertible elements and 2R
Abstract
In this paper we prove that every automorphism of a Chevalley group with the root system G2 over a commutative ring R with 1/3, generated by all its invertible elements and the ideal 2R is a composition of ring and inner automorphisms.
