• Abstract:
  Under some cardinal arithmetic assumptions, we prove that many stationary subsets of \lambda of a right cofinality has the “middle diamond”. In particular, for many regular \kappa for every large enough regular \lambda we have the middle diamond on \{\delta<\lambda:{\rm cf}(\delta)=\kappa\}. This is a strong negation of uniformization.
