How many miles to bw? II - non-rapid ultrafilters and Higson compactifications

Masaru Kada

We prove the following theorem: If there is a base F of a non-rapid ultrafilter on w, then we can approximate bw by |F|-many Higson compactifications of w in a nontrivial way.

Keywords: Higson compactification, Stone-Cech compactification, rapid ultrafilter
