Explicit example of collapsing kappa^+ in iteration of kappa-proper forcings

Logic 2018-08-07 v1

Abstract

We give an example of iteration of length omega of (<kappa)-complete kappa^+-cc forcing notions with the limit collapsing kappa^+. The construction is decoded from the proof of Shelah [Proper and Improper Forcing, Appendix, Theorem 3.6(1)].
