On Endomorphism of Algebraic Varieties

Algebraic Geometry 2021-04-02 v2

Abstract

We prove that a quasi-finite endomorphism of an algebraic variety over an algebraically closed field of characteristic zero, that is injective on the complement of a closed subvariety, is an automorphism. We also prove that an endomorphism of complex algebraic variety that is injective on the complement of a closed subvariety of codimension at least 22, is an automorphism.
