Let be the subspace of consisting of all weak -points. It is not hard to see that is a pseudocompact space. In this paper we shall prove that this space has stronger pseudocompact properties. Indeed, it is shown that is a -pseudocompact space for all .
For a free ultrafilter on ,
the concepts of strong pseudocompactness,
strong -pseudocompactness and
pseudo--boundedness were
introduced in [Angoa J., Ortiz-Castillo Y.F.,
Tamariz-Mascarúa A., Ultrafilters and
properties related to compactness,
Topology Proc. 43 (2014), 183–200]
and [García-Ferreira S., Ortiz-Castillo Y.F.,
Strong pseudocompact properties of
certain subspaces of ,
submitted]. These properties in a space
characterize the pseudocompactness
of the hyperspace of
compact subsets...
