Easton forcing
WebEaston [Eas70] proved that the contin uum function κ 7→ 2 κ on reg- ular cardinals can be forced to b ehave in any w ay that is consistent with K¨ onig’s Theorem ( κ < cf (2 κ )) and ... WebI'm actually thinking of Long Easton forcing, so I don't want to assume Easton support. Does the above line of reasoning still work? Namely, assume the existence of class-many regular cardinals satisfying CH (or $\lambda^{\lt\lambda} = \lambda$, if that's weaker), and construct the partial class order so that we can fullfil the hypotheses of ...

WebJun 14, 2024 · In addition, Easton's forcing preserves cardinals. Question: Does Easton forcing preserve measurable cardinals? In particular, if $\mu$ is the first measurable, does it remain the first measurable in the extension (measurable here means "there is an $\aleph_1$-complete non principal ultrafilter on $\mu$). WebNov 12, 2024 · Where Cohen only used a set of forcing conditions, Easton used a proper class of forcing conditions. Footnote 26 This allowed him to show that the GCH can be violated almost arbitrarily. The only restrictions for cardinalities of 2 κ for regular κ are given by the requirements that κ < λ implies that 2 κ ≤ 2 λ , and by König’s Theorem:
