Universally measurable sets in generic extensions
A subset of a topological space is said to be universally measurable if it is measured by the completion of each countably additive σ-finite Borel measure on the space, and universally null if it has measure zero for each such atomless measure. In 1908, Hausdorff proved that there exist universally null sets of real numbers of cardinality א1, and thus that there exist at least 2א1 such sets. La...
متن کاملUniversally Baire Sets and Generic Absoluteness
We prove several equivalences and relative consistency results involving notions of generic absoluteness beyond Woodin’s (Σ ̃ 1)λ generic absoluteness for a limit of Woodin cardinals λ. In particular, we prove that two-step ∃R(Π ̃ 1)λ generic absoluteness below a measurable cardinal that is a limit of Woodin cardinals has high consistency strength, and that it is equivalent with the existence of ...
متن کاملUniversally measurable subgroups of countable index
We prove that any countable index, universally measurable subgroup of a Polish group is open. By consequence, any universally measurable homomorphism from a Polish group into the infinite symmetric group S∞ is continuous. We also show that a universally measure homomorphism from a Polish group into a second countable, locally compact group is necessarily continuous. The present work is motivate...
متن کاملDegrees of subsets of the measurable cardinal in Prikry generic extensions
We prove that in a Prikry generic extension for a measure U on κ every subset of the measurable cardinal κ in the Prikry extension is constructibly equivalent, over the ground model, to a subsequence of the Prikry sequence.
متن کاملUniversally Meager Sets
We study category counterparts of the notion of a universal measure zero set of reals. We say that a set A ⊆ R is universally meager if every Borel isomorphic image of A is meager in R. We give various equivalent definitions emphasizing analogies with the universally null sets of reals. In particular, two problems emerging from an earlier work of Grzegorek are
