Bounded stationary reflection II

Abstract

Bounded stationary reflection at a cardinal λ\lambda is the assertion that every stationary subset of λ\lambda reflects but there is a stationary subset of λ\lambda that does not reflect at arbitrarily high cofinalities. We produce a variety of models in which bounded stationary reflection holds. These include models in which bounded stationary reflection holds at the successor of every singular cardinal μ>ω\mu > \aleph_\omega and models in which bounded stationary reflection holds at μ+\mu^+ but the approachability property fails at μ\mu.
