Combinatorics on Ideals and Forcing
A natural generalization of Cohen's set of forcing conditions (the t w ~ valued functions with domain a finite subset of w) is the set of twovalued functions with domain an element of an ideal J on ~. The I~roblem treated in this paper is to determine when such forcing yields a generic real of minimal degree of constructibility. A :;imple decomposition argument shows that the non-maximality of ...
متن کاملUniversal forcing notions and ideals
The main result of this paper is a partial answer to [6, Problem 5.5]: a finite iteration of Universal Meager forcing notions adds generic filters for many forcing notions determined by universality parameters. We also give some results concerning cardinal characteristics of the σ–ideals determined by those universality parameters. One of the most striking differences between measure and catego...
متن کاملCombinatorics and geometry of power ideals
We investigate ideals in a polynomial ring which are generated by powers of linear forms. Such ideals are closely related to the theories of fat point ideals, Cox rings, and box splines. We pay special attention to a family of power ideals that arises naturally from a hyperplane arrangement A. We prove that their Hilbert series are determined by the combinatorics of A, and can be computed from ...
متن کاملWoodin's axiom (*), bounded forcing axioms, and precipitous ideals on ω₁
If the Bounded Proper Forcing Axiom BPFA holds, then Mouse Reflection holds at א2 with respect to all mouse operators up to the level of Woodin cardinals in the next ZFC–model. This yields that if Woodin’s Pmax axiom (∗) holds, then BPFA implies that V is closed under the “Woodin-in-the-nextZFC–model” operator. We also discuss stronger Mouse Reflection principles which we show to follow from st...
متن کاملForcing Axioms, Supercompact Cardinals, Singular Cardinal Combinatorics
The purpose of this communication is to present some recent advances on the consequences that forcing axioms and large cardinals have on the combinatorics of singular cardinals. I will introduce a few examples of problems in singular cardinal combinatorics which can be fruitfully attacked using ideas and techniques coming from the theory of forcing axioms and then translate the results so obtai...
