Abstract

It is consistent that for many cardinals λ there is a family of at least λ+ unbounded subsets of λ which have uniformization properties. In particular if it is consistent that a supercompact cardinal exists, then it is consistent that ℵω has such a family. We have applications to point set topology, Whitehead groups and reconstructing separable abelian p-groups from their socles.
