The nonstationary ideal on P_\kappa(lambda) for lambda singular

Logic 2007-05-23 v1

Abstract

Let kappa be a regular uncountable cardinal and lambda > kappa a singular strong limit cardinal. We give a new characterization of the nonstationary subsets of P_kappa (lambda) and use this to prove that the nonstationary ideal on P_kappa (lambda) is nowhere precipitous.
