A weak* separable C(K)* space whose unit ball is not weak* separable
Antonio Avilés, Grzegorz Plebanek, José Rodríguez
We provide a ZFC example of a compact space K such that C(K)* is w*-separable but its closed unit ball is not w*-separable. All previous examples of such kind had been constructed…
On measures on Rosenthal compacta
Witold Marciszewski, Grzegorz Plebanek
We show that if K is Rosenthal compact which can be represented by functions with countably many discontinuities then every Radon measure on K is countably determined. We also pres…
A dichotomy for the convex spaces of probability measures
Mikołaj Krupski, Grzegorz Plebanek
We show that every nonempty compact and convex space M of probability Radon measures either contains a measure which has `small' local character in M or else M contains a measure o…
Measurability in C(2^k) and Kunen cardinals
Antonio Avilés, Grzegorz Plebanek, José Rodríguez
A cardinal k is called a Kunen cardinal if the sigma-algebra on k x k generated by all products AxB, coincides with the power set of k x k. For any cardinal k, let C(2^k) be the Ba…
