The 2-categorical universal property of the optic construction
The 2-categorical universal property of the optic construction
Let be the sub-2-category of symmetric monoidal categories whose 2-morphisms are natural isomorphisms, and let be the 2-category of teleological categories, functors, and teleological natural isomorphisms. Write for the optic construction and for the underlying dualisable-morphisms functor.
Optic biadjunction conjecture. The functor
is left biadjoint to
The preceding strict universal property establishes the analogous ordinary adjunction for strict monoidal categories. This conjectural extension would provide the corresponding 2-categorical universal property for non-strict monoidal categories, restricted to natural isomorphisms.
