Main Body


1: Definition


For any structure, \(S\), any morphism, \(f: S \to S\)


2: Note


Often called just "endomorphism", any morphism is never just a "endomorphism", but a group endomorphism, a vectors space endomorphism, etc., depending on what kind of structure the morphism is regarded to be of, which is the reason why the title of this article is "%structure kind name% endomorphism" with "%structure kind name%" as a place holder.

For example, when the domain and the codomain, \(S\), is a vectors space (which means that that is automatically also a group with addition as the group operation), a map may be a group endomorphism, but not a vectors space endomorphism.
