Localization is the process of inverting a specified class of maps.


Consider a family F: (a:A)B(a)C(a) \prod_{(a:A)} F:\prod_{(a:A)} B(a) \to C(a) of maps. We say that a type XX is FF-local if the function

λg.g (F(a)):(C(a)X)(B(a)X) \lambda g . g \circ (F(a)) F(a) : (C(a) \to X) \to (B(a) \to X)

is an equivalence . for all (a : A).
