Applications of another characterization of betaN
Alan Dow, Klaas Pieter Hart
Abstract
Steprans provided a characterization of betaN in the aleph2-Cohen model that is much in the spirit of Parovicenko's characterization of this space under CH. A variety of the topological results established in the Cohen model can be deduced directly from the properties of betaN or P(N)/fin that feature in Steprans' result.
