Related to Endomorphism: Epimorphism


A function from a set with some structure (such as a group, ring, vector space, or topological space) to itself which preserves this structure.



a mapping of a set into itself in which the algebraic operations and relations defined on the set are preserved. For example, the mapping x → 2x is an endomorphism of an additive group of whole numbers, such that 2(x + y) = 2x + 2y.
