Normalizers of chevalley groups of type G₂ over local rings without 1/2

In this paper, we prove that every element of the linear group GL₁₄(R) normalizing the Chevalley group of type G₂ over a commutative local ring R without 1/2 belongs to this group up to some multiplier. This allows us to improve our classification of automorphisms of these Chevalley groups showing that an automorphism-conjugation can be replaced by an inner automorphism. Therefore, it is proved that every automorphism of a Chevalley group of type G₂ over a local ring without 1/2 is a composition of a ring and an inner automorphisms.
