On the existence of a σ-closed dense subset∗
It is consistent with the axioms of set theory that there are two codense partial orders, one of them σ-closed and the other one without a σ-closed dense subset.
متن کاملStationary countable dense random sets
We study the probability theory of countable dense random subsets of (uncountably infinite) Polish spaces. It is shown that if such a set is stationary with respect to a transitive (locally compact) group of symmetries then any event which concerns the random set itself (rather than accidental details of its construction) must have probability zero or one. Indeed the result requires only quasi-...
متن کاملNearly Countable Dense Homogeneous Spaces
We study separable metric spaces with few types of countable dense sets. We present a structure theorem for locally compact spaces having precisely n types of countable dense sets: such a space contains a subset S of size at most n−1 such that S is invariant under all homeomorphisms of X and X \ S is countable dense homogeneous. We prove that every Borel space having fewer than c types of count...
متن کاملCountable Dense Homogeneity of Definable Spaces
We investigate which definable separable metric spaces are countable dense homogeneous (CDH). We prove that a Borel CDH space is completely metrizable and give a complete list of zero-dimensional Borel CDH spaces. We also show that for a Borel X ⊆ 2 the following are equivalent: (1) X is Gδ in 2 ω , (2) X is CDH and (3) X is homeomorphic to 2 or to ω . Assuming the Axiom of Projective Determina...
متن کاملUngar’s Theorems on Countable Dense Homogeneity Revisited
In this paper we introduce a slightly stronger form of countable dense homogeneity that for Polish spaces can be characterized topologically in a natural way. Along the way, we generalize theorems obtained by Bennett and Ungar on countable dense homogeneity.
