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.
