Endomorphisms and automorphisms

Endomorphism

An endomorphism is a morphism that [meets what criteria?].

For an object A in category C the set of endomorphisms of A are all morphisms in [what set?], which is denoted as EndC(A).

Automorphism

An automorphism is a morphism that [meets criteria 1] and [criterial 2].

For an object A in category C, the set of automorphisms for A is denoted as AutC(A). AutC(A) is a subset of [what set?].
