Simpler Short Extenders Forcing- Preserving Strong Cardinals
نویسنده
چکیده
Our aim is to define a version of a simpler short extenders forcing preserving strong cardinals. 1 The Main Preparation Forcing In this section we will redefine the preparation forcing of [6] in order to allow eventually to preserve strong cardinals. The definition will follow those of [6] with certain additions. Fix two cardinals κ and θ such that κ < θ and θ is regular. Definition 1.1 The set P ′ consists of all sequences of triples. 〈〈A , A , C 〉 | τ ∈ s〉

A Simpler Short Extenders Forcing - gap 3 Moti Gitik
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 the preparation forcing is split compl...
متن کاملCombining Short extenders forcings with Extender based Prikry
Change first the cofinality of κ to ω by adding a Prikry sequence ⟨κn | n < ω⟩ such that each κn is κ +n+2 n –strong. Then use the short extenders forcing which adds κ +ω+2 many cofinal ω-sequences to κ (after the preparation or simultaneously with it). All cardinals will be preserved then. If one does not care about falling of κ, then preform Gap 2 short extenders forcing. As a result κ will t...
متن کاملSimpler Short Extenders Forcing - arbitrary gap
Our aim is to present a version of short extenders forcing which splits between cardinals above and below the critical cardinal and allows to blow up the power arbitrary higher. 1 The Main Preparation Forcing The definition of the forcing below follows the ideas of [1], [2], [3], [4]. We extend the method of [4] to gaps up to κ. The forcing adds a certain kind of a simplified morass with linear...

متن کاملShort extenders forcings – doing without preparations
We introduce certain morass type structures and apply them to blowing up powers of singular cardinals. As a bonus, a forcing for adding clubs with finite conditions to higher cardinals is obtained.
