In many branches of mathematics, the term map is used to mean a function,[7][3][8]
sometimes with a specific property of particular importance to that branch.
For instance, a "map" is a "continuous function" in topology,
a "linear transformation" in linear algebra, etc.
In the theory of dynamical systems,
a map denotes an evolution function used to create discrete dynamical systems.
A partial map is a partial function.
Related terms such as domain, codomain, injective, and
continuous can be applied equally to maps and functions, with the same meaning.
All these usages can be applied to "maps" as general functions
or as functions with special properties.
