Definitions and Basic Properties of Boolean and
Union of Many Sorted Sets

Artur Kornilowicz

Institute of Mathematics, Warsaw University, Bialystok
Summary.

In the first part of this article I have proved theorems about
boolean of many sorted sets which are corresponded to theorems about
boolean of sets, whereas the second part of this article contains
propositions about union of many sorted sets. Boolean as well as union
of many sorted sets are defined as boolean and union on every sorts.
The terminology and notation used in this paper have been
introduced in the following articles
