Abstract

We establish the consistency of the failure of the diamond principle on a cardinal κ\kappa which satisfies a strong simultaneous reflection property. The result is based on an analysis of Radin forcing, and further leads to a characterization of weak compactness of κ\kappa in a Radin generic extension.
