Spectra of Tukey types of ultrafilters on Boolean algebras
arXiv:1406.2084
Abstract
Extending recent investigations on the structure of Tukey types of ultrafilters on to Boolean algebras in general, we classify the spectra of Tukey types of ultrafilters for several classes of Boolean algebras, including interval algebras, tree algebras, and pseudo-tree algebras.
