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

Spaces which are generated by discrete sets
Continuing the study initiated by Dow, Tkachenko, Tkachuk and Wilson, we prove that countably compact countably tight spaces, normed linear spaces in the weak topology and function spaces over a-compact

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 ch...

Weak compactness and sigma-Asplund generated Banach spaces
, differentiability, and of weak compactness. As a consequence, we provide a functional-analytic proof of a result of Arvanitakis: A compact space is Eberlein if (and onlyIn the framework of weakly Lindelöf determined Banac...

Borel sets with sigma-compact sections for nonseparable spaces
Every Borel $Esu Xtimes Y$, where $X$ is complete metric and $Y$ is Polish, can be covered by countably many extended Borel sets with compact sections if its sections are $sigma$-compact....

Point simpliciality in Choquet theory on nonmetrizable compact spaces
Let H be a function space on a compact space K. The set of simpliciality of H is the set of all points of K for which there exists a unique maximal representing measure. Properties of this set wer...

Weakly compact sets and smooth norms in Banach spaces.
Two smoothness characterisations of weakly compact sets in Banach spaces are given. One that involves pointwise lower semicontinuous norms and one that involves projectional resolutions of identity....

Remarks on Compact Sets in Spaces of Vector Functions.
In this paper some conditions for the relative compactness of subsets of vector functions are given that are analogical to the conditions appearing in the Arzela-Ascoli theorem....
