TITLEInner and Outer Automorphisms in Lie Theory

ABSTRACT For many algebraic and geometric objects, their automorphism groups are topological spaces in natural ways. We say that an automorphism is inner if its lies in the identity component, and is outer otherwise. This concept provides a stronger condition than mere automorphisms. We explore several issues in Lie theory that arise from it.
