Singular cofinality conjecture and a question of Gorelic

Logic 2015-06-26 v1

Abstract

We give an affirmative answer to a question of Gorelic \cite{Gorelic}, by showing it is consistent, relative to the existence of large cardinals, that there is a proper class of cardinals α\alpha with cf(α)=ω1cf(\alpha)=\omega_1 and αω>α.\alpha^\omega > \alpha.
