Abstract

We establish the equiconsistency of a simple statement in definability theory with the failure of the GCH at all infinite cardinals. The latter was shown by Foreman and Woodin ([2]) to be consistent, relative to the existence of large cardinals. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
