Mathias forcing and combinatorial covering properties of filters

Logic 2015-12-29 v2 General Topology

Abstract

We give topological characterizations of filters FF on ww such that the Mathias forcing MFM_F adds no dominating reals or preserves ground model unbounded families. This allows us to answer some questions of Brendle, Guzm\'an, Hru\v{s}\'ak, Mart\'{\i}nez, Minami, and Tsaban.
