Bounds for Covering Numbers
Journal of Symbolic Logic 71 (4):1303 - 1310 (2006)
Abstract
Let Λ be a singular cardinal of uncountable confinality ψ. Under various assumptions about the sizes of covering families for cardinals below Λ, we prove upper bounds for the covering number cov(Λ, Λ, v⁺, 2). This covering number is closely related to the cofinality of the partial order ([Λ]", ⊆)DOI
