In Prikry forcing (after Karel Prikrý) P is the set of pairs (s, A) where s is a finite subset of a fixed measurable cardinal κ, and A is an element of a fixed normal measure D on κ. A condition (s, A) is stronger than (t, B) if t is an initial segment of s, A is contained in B, and s is contained in t ∪ B. This forcing notion can be used to change to cofinality of κ while preserving all cardinals. WebThe Proper Forcing Axiom, Prikry Forcing, and the Singular Cardinals Hypothesis.

In Part I of this series [PRS20], we introduced a class of notions of forcing which we call -Prikry, and showed that many of the known Prikry-type notions of forcing that center around singular cardinals of countable co nality are -Prikry.
WebAnother interesting research in the field of Prikry forcing, is the investigation of intermediate ZFC models of Prikry forcing extensions. Gitik, Koepke and Kanovei, proved that an intermediate ZFC model of Prikry forcing with a normal ultrafilter U, must also be a Prikry extension of the ground model for Prikry forcing with the same U [8]. town tavern akron ohioWebIn Part I of this series [5], we introduced a class of notions of forcing which we call Σ-Prikry, and showed that many of the known Prikry-type notions of forcing that centers around … town tattler in the great gatsbyhttp://jdh.hamkins.org/tag/inverse-limits/ town tavern alameda caWeb§2.
