An algebra on a set X is a family of subsets of this set closed under the operations of union and difference of two subsets. The main topic of the book is the study of various algebras and families of algebras on an abstract set X. The author shows how this is related to famous …
This work is a systematic study of ideals over uncountable sets. In particular, we investigate the role of various properties of ideals in arithmetic of cardinal numbers. We also study consequences of existence of precipitous ideals for the generalized continuum hypothesis and t…

The main results of this work can be formulated in such a way that they will attract a broad spectrum of mathematical interest, but the main audience includes combinatorialists, set-theorists, and topologists. This paper explores a central question: Suppose one is given an at mo…
