Prikry-type forcing and the set of possible cofinalities

http://homepages.math.uic.edu/~sinapova/Sigma%20Prikry%202.pdf WebThe classical Prikry forcing first appeared in Prikry 's disserta-tion [9] in 1970. It gave a positive answer to the following question of Silver and Solovay: Is there a forcing preserving all cardinals while some cofinality changes? In fact, the singularization of regular cardinals by some forcing is necessarily con-nected with Prikry forcing. unwsp scholarshipsWebthe introduction in [5, 6]). The proofs of these results often rely on forcing methods, such as in [18, 16]. For further discussions on the Halpern-L¨auchli theorem and its generalizations, refer to [5, 6, 17].

In this paper, we give an interval … 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.
