Hello all,

Has anyone studied pairs of functors for which there exists a unit,
but not a counit? Is there a name for such things?

In the case of interest, the functors are between Cat and Met, the
category of (extended pseudo-) metric spaces and 1-Lipschitz maps. The
unit provides a characterization of certain coherent maps of metric
spaces. Further details may be found in
https://arxiv.org/abs/1603.07406.

Thanks,
Peter
