Abstract
Stably compact spaces are a natural generalization of compact Hausdorff spaces in the T0 setting. They have been studied intensively by a number of researchers and from a variety of standpoints.In this paper we let the morphisms between stably compact spaces be certain “closed relations” and study the resulting categorical properties. Apart from extending ordinary continuous maps, these morphisms have a number of pleasing properties, the most prominent, perhaps, being that they correspond to preframe homomorphisms on the localic side. We exploit this Stone-type duality to establish that the category of stably compact spaces and closed relations has bilimits.
