Natural examples of Valdivia compact spaces
We collect examples of Valdivia compact spaces, their continuous images and associated classes of Banach spaces which appear naturally in various branches of mathematics. We focus on topological constructions generating Val...

Overclasses of Radon-Nikodým compact spaces
We map the state of arts of the class of Radon-Nikodým compact spaces and some image of a Radon-Nikodým compact space is such. We consider classes of quasi-Radon-Nikodým, strongly fragmentable, and countably lower ...

Note on Countable Unions of Corson Countably Compact Spaces
We show that a compact space K has a dense set of G-delta points if it can be covered by countably many Corson countably compact spaces. If these Corson countably compact spaces may be chosen to b...

Compactness in Banach space theory - selected problems
We list a number of problems in several topics related to compactness in nonseparable Banach spaces. Namely, about the Hilbertian ball in its weak topology, spaces of continuous functions on Eberlein compacta, WCG Banach

Parovičenko spaces with structures
We study an analogue of the Parovienko property in categories of compact spaces with additional structures. In particular, we present an internal characterization of this property in the class of compact median spaces

Almost-compact embeddings
We study almost-compact embeddings between Banach function spaces. We prove study the dependence of an almost-compact embedding on the measure space. We introduce a certain product operator and show its intimate re...

Compactness in quasi-Banach function spaces and applications to compact embeddings of Besov-type spaces
for the precompactness of sets in Banach function spaces to the setting of quasi-Banach function spaces. The second is to extend the criterion for the precompactness of sets in the Lebesgue spaces Lp(ℝn ), 1 p < , to the ...
