Set theory without choice: not everything on cofinality is possible
نویسنده
چکیده
We prove in ZF+DC, e.g. that: if μ = |H(μ)| and μ > cf(μ) > א0 then μ is regular but non measurable. This is in contrast with the results on measurability for μ = אω due to Apter and Magidor [ApMg]. ∗Research supported by “The Israel Science Foundation” administered by The Israel Academy of Sciences and Humanities.

Cofinality and Measurability of the First Three Uncountable Cardinals
This paper discusses models of set theory without the Axiom of Choice. We investigate all possible patterns of the cofinality function and the distribution of measurability on the first three uncountable cardinals. The result relies heavily on a strengthening of an unpublished result of Kechris: we prove (under AD) that there is a cardinal κ such that the triple (κ, κ+, κ++) satisfies the stron...
متن کاملSplitting stationary sets from weak forms of Choice
Working in the context of restricted forms of the Axiom of Choice, we consider the problem of splitting the ordinals below λ of cofinality θ into λ many stationary sets, where θ < λ are regular cardinals. This is a continuation of [5]. In this note we consider the issue of splitting stationary sets in the presence of weak forms of the Axiom of Choice plus the existence of certain types of ladde...

Anotated Content §0 Introduction §1 On pseudo true cofinality, pg.2 [We continue [Sh:938, §5] to try to generalize the pcf theory for ℵ 1-complete filters D on Y assuming DC + AC P(Y). So is similar to [Sh:b, ChXII]. We suggest to replace cofinality by pseudo cofinality.] §2 Depth of reduced power of ordinals, pg.10 [Using the independence property for a sequence of filters we can bound the rel...
متن کاملThe Comparison of the Effects of Choice Theory Therapy and Behavioral Activation Therapy with and without Guided Mental Imagery on Resilience in Substance-Dependent Adolescents
Objective: This study aimed to compare the effects of choice theory therapy and behavioral activation (BA) therapy with and without guided mental imagery on resilience in substance-dependent adolescents. Method: The present study was quasi-experimental with pretest-posttest design with a control group. The study sample included 60 substance-dependent adolescents who were selected by convenience...
متن کاملThe Theory of Everything vs the Theory of Anything
It is often stated that physicists are concerned with producing a “Theory of Everything”. However, it is clear that we shall never probe all possible interactions at all possible energies. By our very nature we are limited to exploring a very special part of superspace, where spacetime behaves nice and classically, and where matter is distributed in a very orderly way. Indeed we benefit greatly...
