Abstract

We extend the results of [1], showing the consistency of GCH with the statement that for all regular cardinals κ ≤ λ, where κ is the successor of a regular cardinal, there is a rigid saturated ideal on \(\mathcal{P}_\kappa\lambda\). We also show the consistency of some instances of rigid saturated ideals on \(\mathcal{P}_\kappa\lambda\) where κ is the successor of a singular cardinal.
