More rigid ideals

Logic 2019-01-09 v1

Abstract

We extend prior results of Cody-Eskew, showing the consistency of GCH with the statement that for all regular cardinals κλ\kappa \leq \lambda, where κ\kappa is the successor of a regular cardinal, there is a rigid saturated ideal on Pκλ\mathcal{P}_\kappa\lambda. We also show the consistency of some instances of rigid saturated ideals on Pκλ\mathcal{P}_\kappa\lambda where κ\kappa is the successor of a singular cardinal.
