equivalence > history (Rev #7)
Idea
There are multiple definitions of equivalence that are valid in homotopy type theory
Definition
Bijective correspondences
Let be a universe and and be terms of the universe, and be a correspondence? between and . We define the property of being bijective as follows:
We define the type of equivalences from to in as
Contractible fibers
Bi-invertible maps
Quasi-inverses
Half adjoint equivalences
