Abstract

In the book Uniform Spaces by Isbell it is wrongfully claimed that the Hausdorff uniformities associated with two distinct uniform structures on a set X define distinct hyperspace topologies. The question for which uniformities this claim is in fact true became known as the Isbell-Smith problem. In this talk we will take a closer look at the Isbell-Smith problem for quasi-uniform spaces. In particular, we will study the properties of QH-singular quasi-uniform spaces and describe the QH-equivalence class of a transitive quasi-uniformity.
