Free Boolean algebras and nowhere dense ultrafilters

A. Błaszczyk

Abstract An analogue of Mathias forcing is studied in connection of free Boolean algebras and nowhere dense ultrafilters. Some applications to rigid Boolean algebras are given.


Open Mathematics | 2014

Boolean algebras admitting a countable minimally acting group

A. Błaszczyk; Andrzej Kucharski; Sławomir Turek

The aim of this paper is to show that every infinite Boolean algebra which admits a countable minimally acting group contains a dense projective subalgebra.


Topology and its Applications | 2003

Extension of Vladimirov's lemma

Angelo Bella; A. Błaszczyk; Andrzej Kucharski

Abstract In the paper we consider an extension of Vladimirovs lemma on independent sets in complete Boolean algebras. As an application we obtain a criterion for existence of maximal independent families in compact spaces.
