# Non-canonical isomorphisms

## Idea

Often in category theory, requirements that certain things “be isomorphic” are more precisely stated as saying that a certain “canonical” morphism is invertible. However, in certain situations, it happens that the existence of a non-canonical isomorphism automatically entails the “correct” stronger property that the canonical morphism is invertible.

For now, see the references for details.
