Streszczenie
Assuming the continuum hypothesis, we show that
(i) there is a compact convex subset $L$ of ${\mit \Sigma }({{\mathbb R}}^{\omega _{1}})$, and a probability Radon measure on $L$ which has no separable support;
(ii) there is a Corson compact space $K$, and a convex weak$^*$-compact set $M$ of Radon probability measures on $K$ which has no $G_{\delta }$-points.
