Abstract
The notion of -stationary subsets of for were introduced and studied by Cody, Lambie-Hanson \& Zhang \cite{CLHZ} and Torres \cite{T}. They proved that if is supercompact, then is -stationary in itself for all cardinals and all . In this paper we prove that strong compactness of does not imply the -stationarity of for cardinals . We also discuss Menas' Theorem for -stationary and -stationary subsets of .
