Precipitous Towers of Normal Filters

Logic 2016-09-06 v1

Abstract

We prove that every tower of normal filters of height \gd\gd (\gd\gd supercompact) is precipitous assuming that each normal filter in the tower is the club filter restricted to a stationary set. We give an example to show that this assumption is necessary. We also prove that every normal filter can be generically extended to a well-founded VV-ultrafilter (assuming large cardinals).
