Claims

C1strongest claim

We characterize virtual double categories of enriched categories, functors, and profunctors by introducing a new notion of double-categorical colimits. Our characterization is strict in the sense that it is up to equivalence between virtual double categories and, at the level of objects, up to isomorphism of enriched categories.

C2weakest assumption

The choice to treat enrichment in a unital virtual double category rather than in a bicategory or a monoidal category, together with the adoption of augmented virtual double categories as the fundamental language for double-categorical concepts.

C3one line summary

Characterizes virtual double categories of enriched categories, functors, and profunctors via a new notion of double-categorical colimits, strictly up to equivalence.
