Star and strong star-type versions of Rothberger and Menger principles for hit-and-miss topology

Topology and Its Applications, 2021
Let \(X\) be a space and denote by \(\mathcal{D}\) the family of dense subsets in the hyperspace of nonempty closed subsets with the hit-and-miss topology. The reviewer in [\textit{Z. Li}, Topology Appl. 212, 90--104 (2016; Zbl 1355.54014)] defined the concepts of \(\pi_{F}\)-network and \(\pi_{V}\)-network, obtaining many interesting results.

Wijsman and Hit-and-Miss Topologies of Quasi-Metric Spaces

Set-Valued Analysis, 2003
The authors study the relationship between the Wijsman topology and (proximal) hit-and-miss topologies on hyperspaces of quasi-metric spaces. They establish the equivalence of these hypertopologies in terms of Urysohn families of sets. They also show that for quasi-metric spaces \((X,d)\), the Hausdorff extended quasi-pseudo-metric is compatible with ...

The \(\pi\)-weights and \(\pi\)-characters of hyperspaces with the hit-and-miss topologies

2011
For a topological space \(X\), let \(2^X\) be the set of all closed subsets of \(A\) and \(\text{CL}(X)=2^X-\{\emptyset\}\). \(\Delta\) denotes a subset of \(\text{CL}(X)\) satisfying the following properties: (a) \(\Delta\) is closed with respect to the finite unions; (b) the intersection of every finite subset of \(\Delta\) belongs to \(\Delta\) if ...
