A Simpler Short Extenders Forcing - gap 3 Moti Gitik

Abstract

Assume GCH. Let κ = ⋃ n<ω κn, 〈κn | n < ω〉 increasing, each κn is κ n – strong witnessed by (κn, κ +n+3 n ) – extender En. We would like to force 2 = κ preserving all the cardinals and without adding new bounded subsets to κ. It was done first in [2, Sec.3]. Here we present a different method of doing this. The advantage of the present construction is that… (More)
