Number of Ultrafilters, subalgebra or homomorphic image of ., then |Ult.| ≤ |Ult.|. For weak products we have .. The situation for full products is more complicated: ., where . = Σ. d... This follows from the following two facts: .where “→” means “is isomorphically embeddable in”, and “U” means “disjoint union”. Next, cle

Introduction, shortly be more specific about what these three general questions amount to. The purpose of these notes is to survey this area of the theory of BA’s, giving proofs for a large number of results, some of which are new, mentioning most of the known results, and formulating open problems. The open pro
