Ungar’s Theorems on Countable Dense Homogeneity Revisited

چکیده
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.

Open Problems on Countable Dense Homogeneity
We survey recent development in research on countable dense homogeneity with special emphasis on open problems.
متن کاملOn Countable Dense and n-homogeneity
We prove that a connected, countable dense homogeneous space is n-homogeneous for every n, and strongly 2-homogeneous provided it is locally connected. We also present an example of a connected and countable dense homogeneous space which is not strongly 2-homogeneous. This answers in the negative Problem 136 of Watson in the Open Problems in Topology Book.
متن کاملSome Notes concerning the Homogeneity of Boolean Algebras and Boolean Spaces
In this article we consider homogeneity properties of Boolean algebras that have nonprincipal ultrafilters which are countably generated. It is shown that a Boolean algebra B is homogeneous if it is the union of countably generated nonprincipal ultrafilters and has a dense subset D such that for every a ∈ D the relative algebra B 1 a := {b ∈ B : b ≤ a} is isomorphic to B. In particular, the fre...
متن کاملCountable dense homogeneity and λ - sets
We show that all sufficiently nice λ-sets are countable dense homogeneous (CDH). From this fact we conclude that for every uncountable cardinal κ ≤ b there is a countable dense homogeneous metric space of size κ. Moreover, the existence of a meager in itself countable dense homogeneous metric space of size κ is equivalent to the existence of a λ-set of size κ. On the other hand, it is consisten...
متن کاملHomogeneous Countable Connected Hausdorff Spaces
In 1925, P. Urysohn gave an example of a countable connected Hausdorff space [4]. Other examples have been contributed by R. Bing [l], M. Brown [2], and E. Hewitt [3]. Relatively few of the properties of such spaces have been examined. In this paper the question of homogeneity is studied. Theorem I shows that there exists a bihomogeneous countable connected Hausdorff space. Theorems II and III ...
