Abstract

We study a concept of hyperconvexity that is appropriate to the category of T0-quasi-metric spaces (called di-spaces in the following) and nonexpansive maps. An explicit construction of the corresponding hull (called Isbell-convex hull or, more briefly, Isbell-hull) of a di-space is provided.
