Easton forcing
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: http://pcorazza.lisco.com/papers/hod-wa.pdf

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 $\mu$).

The manuscript is a dependable source of information for mathematicians and researchers interested in set theory. crypto mining plantWebRecall that Easton forcing was introduced to show that the continuum function at regular cardinals could be anything subject to 'the obvious constraints' (monotonicity etc). However, it is a handy method if one wants to add a proper class of sets. cryptorchidism in dogs and catsWebEaston's work was notable in that it involved forcing with a proper class of conditions. In general, the method of forcing with a proper class of conditions will fail to give a model of ZFC. For example, Fin ( ω × On , 2 ), where "On" is the proper class of all ordinals, will make the continuum a proper class. cryptorchidism in livestockWebEaston forcing preserves that 2 = + for singular (this is an exercise in Jech).
