A Special Class of Almost Disjoint Families
The collection of branches (maximal linearly ordered sets of nodes) of the tree ω (ordered by inclusion) forms an almost disjoint family (of sets of nodes). This family is not maximal – for example, any level of the tree is almost disjoint from all of the branches. How many sets must be added to the family of branches to make it maximal? This question leads to a series of definitions and result...
متن کاملConfinitary Groups, Almost Disjoint and Dominating Families
In this paper we show that it is consistent with ZFC that the cardinality of every maximal cofinitary group of Sym(ω) is strictly greater than the cardinal numbers d and a.
متن کاملMartin's axiom and almost disjoint families
Assuming Martin’s Axiom and א1 < 2 א0 , we show that, for any κ, λ < 20 and any almost disjoint family {ai : i < λ} of countable subsets of κ, there is a partition {pn : n ∈ ω} of κ so that pn ∩ ai is finite for each 〈i, n〉 ∈ λ × ω.
متن کاملCofinitary Groups, almost Disjoint and Dominating Families
In this paper we show that it is consistent with ZFC that the cardinality of every maximal cofinitary group of Sym(co) is strictly greater than the cardinal numbers D and a. ?
متن کاملInvariance properties of almost disjoint families
We answer a question of Gracia-Ferreira and Hrušák by constructing consistently a MAD family maximal in the Katětov order. We also answer several questions of Garcia-Ferreira.
