Calculus on strong partition cardinals
نویسنده
چکیده
The assumption of [HM] and our assumption here, the existence of a strong partition cardinal, is moderately special. On the one hand, it violates the Axiom of Choice and is not relatively consistent with ZF (unlike AC and its negation). On the other hand, under the Axiom of Determinacy (AD), such cardinals are abundant and consistent with countable choice and DC, the principle of Dependent Choices. א1, for example, is a strong partition cardinal and there are strong partition cardinals that are the limits of strong partition cardinals. AD itself, while once considered unimaginably powerful, seems fairly tame now by the yardstick of the large cardinal axiom hierarchy (well below supercompact cardinals in consistency strength). See [Ka] for details.

A Note on Strong Negative Partition Relations
We analyze a natural function definable from a scale at a singular cardinal, and provide a fairly simple proof that there is a strong connection between failures of square brackets partition relations at sucessors of singular cardinals and the club–guessing ideal idp(C̄, Ī).
متن کاملA Polarized Partition Relation and Failure of Gch at Singular Strong Limit Sh586
The main result is that for λ strong limit singular failing the continuum hypothesis (i.e. 2 > λ), a polarized partition theorem holds. § 0. Introduction In the present paper we show a polarized partition theorem for strong limit singular cardinals λ failing the continuum hypothesis. Let us recall the following definition. {jeden} Definition 0.1. For ordinal numbers α1, α2, β1, β2 and a cardina...
متن کاملThe Calculus of Partition Sequences, Changing Cofinalities, and a Question of Woodin
We study in this paper polarized infinite exponent partition relations. We apply our results to constructing a model for the theory “ZF+DC+ω1 is the only regular, uncountable cardinal ≤ ωω1+1.” This gives a partial answer to a question of Woodin. In 1994, J. Steel proved what had long been suspected: that assuming AD, the regular cardinals of L(R) below Θ are all measurable, where Θ is the leas...
متن کاملCofinality 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 The result relies heavily on a strengthening of an unpublished result of Kechris: we prove (under AD) that there is a cardinal κ such that the triple (κ, κ+, κ++) satisfies the stron...

Kanamori, A., Regressive partition relations, n-subtle cardinals, and Bore1 diagonalization, Annals of Pure and Applied Logic 52 (1991) 65-77. We consider natural strengthenings of H.

After providing a systematic survey of regressive partition relations and their use in ...
