Abstract:
We prove that, consistently, there exists a weakly but not strongly inaccessible cardinal \lambda for which the sequence \langle 2^\theta:\theta<\lambda\rangle is not eventually constant and the weak diamond fails at \lambda. We also prove that consistently diamond fails but a parametrized version of weak diamond holds at some strongly inaccessible - Version 2020-02-11 (15p) published version (13p)
