∗ Research supported by Hungarian National Foundation for Scientific Research, Grant No T 016094. In a quasi-uniform space, firmly D-Cauchy filters are introduced and they role in constructing firm extensions is investigated.

Cofinal completeness of the Hausdorff metric topology

Gerald Beer, Giuseppe Di Maio (2010)

Fundamenta Mathematicae

Similarity:

A net in a Hausdorff uniform space is called cofinally Cauchy if for each entourage, there exists a cofinal (rather than residual) set of indices whose corresponding terms are pairwise within the entourage. In a metric space equipped with the associated metric uniformity, if each cofinally Cauchy sequence has a cluster point, then so does each cofinally Cauchy net, and the space is called cofinally complete. Here we give necessary and sufficient conditions for the nonempty closed subsets...
