Densities of Ultraproducts of Boolean Algebras
We answer three problems by J. D. Monk on cardinal invariants of Boolean algebras. Two of these are whether taking the algebraic density πA resp. the topological density dA of a Boolean algebra A commutes with formation of ultraproducts; the third one compares the number of endomorphisms and of ideals of a Boolean algebra. In set theoretic topology, considerable effort has been put into the stu...
متن کاملLength of Boolean Algebras and Ultraproducts
We prove the consistency with ZFC of “the length of an ultraproduct of Boolean algebras is smaller than the ultraproduct of the lengths”. Similarly for some other cardinal invariants of Boolean algebras.

متن کاملApplications of Pcf Theory Sh589
Abstract. We deal with several pcf problems; we characterize another version of exponentiation: number of κ-branches in a tree with λ nodes, deal with existence of independent sets in stable theories, possible cardinalities of ultraproducts and the depth of ultraproducts of Boolean Algebras. Also we give cardinal invariants for each λ with a pcf restriction and investigate further TD(f). The se...
متن کاملOn incomparability and related cardinal functions on ultraproducts of Boolean algebras
Let C denote any of the following cardinal characteristics of Boolean algebras: incomparability, spread, character, π-character, hereditary Lindelöf number, hereditary density. It is shown to be consistent that there exists a sequence 〈Bi : i < κ〉 of Boolean algebras and an ultrafilter D on κ such that
