The nonstationary ideal on $P_\kappa(\lambda)$ for $\lambda$ singular
by Matet and Shelah. [MtSh:869]
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.
