Abstract
Let g be a finite dimensional simple Lie algebra over an algebraically closed field K of characteristic 0. A linear map Ï:gâg is called a local automorphism if for every x in g there is an automorphism Ïx of g such that Ï(x)=Ïx(x). We prove that a linear map Ï:gâg is local automorphism if and only if it is an automorphism or an anti-automorphism.
