The Ultrafilter Number for Singular Cardinals
We prove the consistency of a singular cardinal λ with small value of the ultrafilter number uλ, and arbitrarily large value of 2 . 2000 Mathematics Subject Classification. 03E05, 03E55.
متن کاملOn the splitting number at Regular Cardinals
Let κ, λ be regular uncountable cardinals such that λ > κ+ is not a successor of a singular cardinal of low cofinality. We construct a generic extension with s(κ) = λ starting from a ground model in which o(κ) = λ and prove that assuming ¬0¶, s(κ) = λ implies that o(κ) ≥ λ in the core model.
متن کاملEquiconsistencies at subcompact cardinals
We present equiconsistency results at the level of subcompact cardinals. Assuming SBHδ, a special case of the Strategic Branches Hypothesis, we prove that if δ is a Woodin cardinal and both 2(δ) and 2δ fail, then δ is subcompact in a class inner model. If in addition 2(δ) fails, we prove that δ is Π21 subcompact in a class inner model. These results are optimal, and lead to equiconsistencies. A...
متن کاملLarge Cardinals and Small Dowker Spaces
We prove that, if there is a model of set-theory which contains no first countable, locally compact, scattered Dowker spaces, then there is an inner model which contains a measurable cardinal. A Hausdorff space is normal if, for every pair of disjoint closed sets C and D, there is a pair of disjoint open sets, U containing C and V containing D. A (normal) space is binormal if its product with t...
متن کاملOn some small cardinals for Boolean algebras
Assume that all algebras are atomless. (1) Spind(A x B) = Spind(A) U Spind(B). (2) Spind(H1-I~ Ai) = {co } U U,Ej Spind(Ai). Now suppose that K and 2 are infinite cardinals, with r uncountable and regular and with r. < 2. (3) There is an atomless Boolean algebra A such that u(A) = te and i(A) = A. (4) If 2 is also regular, then there is an atomless Boolean algebra A such that t(A) = s(A) = K an...
