On closed unbounded sets consisting of former regulars
Published online by Cambridge University Press: 12 March 2014
Abstract
A method of iteration of Prikry type forcing notions as well as a forcing for adding clubs is presented. It is applied to construct a model with a measurable cardinal containing a club of former regulars, starting with ο(κ) = κ + 1. On the other hand, it is shown that the strength of above is at least
ο(κ) = κ.
