WebPrikry forcing, de ne the -tree and uncover some of its features. The proof that the Complete Prikry Property implies the Prikry Property and the Strong Prikry Property may be found … Webstrongly compact cardinal. This was because Prikry forcing above a strongly compact car-dinal adds a weak square sequence, which destroys the strong compactness of the smaller cardinal. Magidor overcame this difficulty by inventing yet another technique for producing non-supercompact strongly compact cardinals. Rather than iterating Prikry ...

It is proved that it is consistent that aleph -omega is strong limit, 2 is large and the universality number for graphs on $\aleph _{\omega + 1} $ is small.

WebOct 19, 2012 · Prikry’s notion of forcing P U is the collection of all pairs ( σ, A) such that. A ∈ U with max ( σ) < min ( A). A condition ( σ 2, A 2) extends ( σ 1, A 1) iff A 2 ⊆ A 1 and σ 2 ∖ σ 1 ⊆ A 1. That is, we are allowed to shrink the A -part, and allowed to end-extend σ by adding to it finitely many elements from A.
