Namba forcing and no good scale
نویسنده
چکیده
We develop a version of Namba forcing which is useful for constructing models with no good scale on אω . A model is produced in which אn holds for all finite n ≥ 1, but there is no good scale on אω ; this strengthens a theorem of Cummings, Foreman, and Magidor [3] on the non-compactness of

Subcomplete Forcing and L-Forcing
ABSRACT In his book Proper Forcing (1982) Shelah introduced three classes of forcings (complete, proper, and semi-proper) and proved a strong iteration theorem for each of them: The first two are closed under countable support iterations. The latter is closed under revised countable support iterations subject to certain standard restraints. These theorems have been heavily used in modern set th...
متن کاملKurepa trees and Namba forcing
We show that compact cardinals and MM are sensitive to λ-closed forcings for arbitrarily large λ. This is done by adding ‘regressive’ λ-Kurepa-trees in either case. We argue that the destruction of regressive Kurepa-trees with MM requires the use of Namba forcing.
متن کاملIncreasing δ 12 and Namba - style forcing ∗ Richard
We isolate a forcing which increases the value of δ 2 while preserving ω1 under the assumption that there is a precipitous ideal on ω1 and a measurable cardinal.
متن کاملA variant of Namba Forcing
Ronald Jensen asked whether it is possible to change cofinality of every regular cardinal between א1 and an inaccessible λ to ω preserving λ (and of course א1). We show that it is possible assuming large cardinals.
متن کاملComplete forcing numbers of polyphenyl systems
The idea of “forcing” has long been used in many research fields, such as colorings, orientations, geodetics and dominating sets in graph theory, as well as Latin squares, block designs and Steiner systems in combinatorics (see [1] and the references therein). Recently, the forcing on perfect matchings has been attracting more researchers attention. A forcing set of M is a subset of M contained...
