Compactness of ωλ for λ singular
We characterize the compactness properties of the product of λ copies of the space ω with the discrete topology, dealing in particular with the case λ singular, using regular and uniform ultrafilters, infinitary languages and nonstandard elements. We also deal with products of uncountable regular cardinals with the order topology. 2010 Mathematics Subject Classification 54B10, 54D20, 03C75 (pri...
متن کاملShelah’s Singular Compactness Theorem
We present Shelah’s famous theorem in a version for modules, together with a self-contained proof and some examples. This exposition is based on lectures given at CRM in
متن کاملThe Nonstationary Ideal on Pκ(λ) for Λ Singular
Let κ be a regular uncountable cardinal and λ > κ a singular strong limit cardinal. We give a new characterization of the nonstationary subsets of Pκ(λ) and use this to prove that the nonstationary ideal on Pκ(λ) is nowhere precipitous. 0 Introduction Let κ be a regular uncountable cardinal and λ > κ a singular cardinal. Let Iκ,λ (respectively, NSκ,λ) denote the ideal of noncofinal (respectivel...
متن کاملCellular Objects and Shelah’s Singular Compactness Theorem
The best-known version of Shelah’s celebrated singular cardinal compactness theorem states that if the cardinality of an abelian group is singular, and all its subgroups of lesser cardinality are free, then the group itself is free. The proof can be adapted to cover a number of analogous situations in the setting of non-abelian groups, modules, graph colorings, set transversals etc. We give a s...
متن کاملStrictly Singular Uniform λ−Adjustment in Banach Spaces
Based on the recently introduced uniform λ−adjustment for closed subspaces of Banach spaces we extend the concept of the strictly singular and nitely strictly singular operators to the sequences of closed subspaces and operators in Banach spaces and prove theorems about lower semi Fredholm stability. We also state some new open questions related to strict singularity and the geometry of Banach ...
