On Marczewski-Burstin representations of algebras and ideals

Balcerzak M., Rzepecka J.

Journal of Applied Analysis

2003

Vol. 9, nr 2

275-286

We study MB-representations of algebras and ideals when they are relativized to a subset, and when one considers the operations of sum and intersection for families of algebras and ideals. We observe that the algebras [wzór], on R are MB-representable under GCH. We find a class of topological spaces in which the algebra of clopen sets is MB-representable.

Marczewski operation can be iterated few times

Wroński S.

Bulletin of the Polish Academy of Sciences. Mathematics

2002

Vol. 50, no 2

217-219

We show that the maximal number of different algebras that can be obtained by the succesive repetitions of Marczewski operation S((.) \ {0}) is 3. This solves the problem from [1].
