Countably tight dual ball with a nonseparable measure
Piotr Koszmider, Zdeněk Silber
We construct a compact Hausdorff space such that the space of Radon probabiblity measures on considered with the weak topology (induced from the space of continu…

On Ramsey-type properties of the distance in nonseparable spheres
Piotr Koszmider
Given an uncountable subset of a nonseparable Banach space, is there an uncountable such that the distances between any two distinct p…

Equilateral and separated sets in some Hilbert generated Banach spaces
Piotr Koszmider, Kamil Ryduchowski
We study Hilbert generated versions of nonseparable Banach spaces considered by Shelah, Steprāns and Wark where the behavior of the norm on nonseparable subsets is so…
