On two consequences of CH established by Sierpinski. II
Roman Pol, Piotr Zakrzewski
We continue a study of the relations between two consequences of the Continuum Hypothesis discovered by Waclaw Sierpinski, concerning uniform continuity of continuous functions and…

We study the relations between two consequences of the Continuum Hypothesis discovered by Wacław Sierpiński, concerning uniform continuity of continuous functions and uniform conve…
A remark on Fremlin-Miller theorem concerning the Menger property and Michael concentrated sets
Jozef Chaber, Roman Pol
The theorem we prove is a slight strengthening of some results by Just, Miller, Scheepers and Szeptycki [JMSS]. We use the Michael technique instead of the combinatorial approach i…
Countably perfectly meager sets
Roman Pol, Piotr Zakrzewski
We study a strengthening of the notion of a perfectly meager set. We say that that a subset of a perfect Polish space is countably perfectly meager in , if for every seq…
On Mazurkiewicz's sets, thin σ-ideals of compact sets and the space of probability measures on the rationals
Roman Pol, Piotr Zakrzewski
We shall establish some properties of thin -ideals of compact sets in compact metric spaces (in particular, the -ideals of compact null-sets for thin subadditive capacities),…
On a problem of Talagrand concerning separately continuous functions
Volodymyr Mykhaylyuk, Roman Pol
We construct a separately continuous function on the product of a Baire space and a zero-dimensional compact space such that no restriction of t…
