Morphisms
#Catagory
Morphisms and objects are constituents of a Category. Morphisms, also called maps or arrows, relate two objects called the source and the target of the morphism.
A morphism is a map between two objects in an abstract category.
- A general morphism is called a homomorphism
- A morphism in a category is a monomorphism if, for any two morphisms , implies that
- A morphism in a category is an epimorphism if, for any two morphisms , implies
- A bijective morphism is called an isomorphism (if there is an isomorphism between two objects, then we say they are isomorphic),
- A surjective morphism from an object to itself is called an endomorphism, and
- An isomorphism between an object and itself is called an automorphism.
