Abstract

We prove that there is a certain degree of independence between stationary reflection phenomena at different cofinalities; e.g. it is consistent that every stationary subset of S13 reflects at a point of cofinality aleph2 while every stationary subset of S30 has a non-reflecting stationary subset
