https://doi.org/10.1007/978-1-349-22916-1By now, we have assumed only that in every algebra we encounter there are a supremum and an infimum of each finite subset (likewise in a general lattice). We now strengthen the requirements on an algebra.

Local Tax Benefits at a DistanceThis chapter is devoted, primarily, to constructing homomorphisms or, equivalently, continuous mappings of Stone spaces. The following extension problem is central here: Let X. be a subalgebra of a Boolean algebra X and let Φ. be a homomorphism from X. into a Boolean algebra Y. Does Φ. admit an extension to a homomorphism Φ from X into Y?

Preliminaries on Boolean AlgebrasEach Boolean algebra is a partially ordered set of a special form. Therefore, we start with some general facts and concepts relating to order.

Complete Boolean AlgebrasBy now, we have assumed only that in every algebra we encounter there are a supremum and an infimum of each finite subset (likewise in a general lattice). We now strengthen the requirements on an algebra.

Representation of Boolean AlgebrasEach Boolean algebra is isomorphic to an algebra of sets. This fact was already mentioned in the preceding chapters. Below, we give an exact formulation and a complete proof of the celebrated Stone Theorem and discuss the problems that arise in connection with this theorem.
