As a corollary to this and a theorem of Jensen, the model L[E] satisfies the Gap-2 Cardinal Transfer Property (κ++,κ)→(λ++,λ) for all infinite cardinals κ and λ.Previous article in issueNext article in issueMSC03E0503E4503E55KeywordsExtender modelFine structureMorassRecommended articlesCited by (0)Copyright © 2008 Elsevier B.V.
