From The Free On-line Dictionary of Computing (18 March 2015) :
inverse
Given a function, f : D -> C, a function g : C
-> D is called a left inverse for f if for all d in D, g (f d)
= d and a right inverse if, for all c in C, f (g c) = c and an
inverse if both conditions hold. Only an injection has a
left inverse, only a surjection has a right inverse and only
a bijection has inverses. The inverse of f is often written
as f with a -1 superscript.
