Cichoń’s maximum without large cardinals
نویسندگان
چکیده
Cichoń’s diagram lists twelve cardinal characteristics (and the provable inequalities between them) associated with ideals of null sets, meager countable and $\sigma$-compact subsets irrationals. It is consistent that all entries are pairwise different (apart from $\operatorname{add}\mathcal{M}$ $\operatorname{cof}\mathcal{M}$, which provably equal to other entries). However, consistency proofs so far required large assumptions. In this work, we show without such

Violating the Singular Cardinals Hypothesis Without Large Cardinals
Easton proved that the behavior of the exponential function 2 at regular cardinals κ is independent of the axioms of set theory except for some simple classical laws. The Singular Cardinals Hypothesis SCH implies that the Generalized Continuum Hypothesis GCH 2 = κ holds at a singular cardinal κ if GCH holds below κ. Gitik and Mitchell have determined the consistency strength of the negation of ...
متن کاملLarge cardinals and definable well-orders, without the GCH
We show that there is a class-sized partial order P with the property that forcing with P preserves ZFC, supercompact cardinals, inaccessible cardinals and the value of 2κ for every inaccessible cardinal κ and, if κ is an inaccessible cardinal and A is an arbitrary subset of κκ, then there is a P-generic extension of the ground model V in which A is definable in 〈H(κ+)V[G],∈〉 by a Σ1-formula wi...
متن کاملLarge Cardinals and Lightface Definable Well-Orders, without the GCH
This paper deals with the question whether the assumption that for every inaccessible cardinal κ there is a well-order of H(κ+) definable over the structure 〈H(κ+),∈〉 by a formula without parameters is consistent with the existence of (large) large cardinals and failures of the GCH. We work under the assumption that the SCH holds at every singular fixed point of the i-function and construct a c...
متن کاملIndescribable cardinals without diamonds
where E is a stationary subset of some cardinal ~. Jensen (cf. I-D2]) showed that if K is regular and uncountable and V=L then O~,E holds. Following his work, a number of applications of this principle and its modifications have been developed which are wide ranging and not restricted to set theory (cf. [-D1]). Jensen had also discovered that various large cardinals carry diamond sequences with...
متن کاملUltrafilters and Large Cardinals
This paper is a survey of basic large cardinal notions, and applications of large cardinal ultrafilters in forcing. The main application presented is the consistent failure of the singular cardinals hypothesis. Other applications are mentioned that involve variants of Prikry forcing, over models of choice and models of determinacy. My talk at the Ultramath conference was about ultrafilters and ...
