Dendrites and symmetric products
Gerardo Acosta, Rodrigo Hernández-Gutiérrez, Verónica Martínez-de-la-Vega
For a given continuum and a natural number we consider the hyperspace of all nonempty subsets of with at most points, metrized by the Hausdorff metric. In…
Countable dense homogeneity and -sets
Rodrigo Hernández-Gutiérrez, Michael Hrušák, Jan van Mill
We show that all sufficiently nice -sets are countable dense homogeneous (). From this fact we conclude that for every uncountable cardinal the…
Countable Dense Homogeneity and the Double Arrow Space
Rodrigo Hernández-Gutiérrez
Let denote the Alexandroff-Urysohn double arrow space. We prove the following results: (a) is not countable dense homogeneous; (b) ${}^ω{\mat…
Non-meager -filters are Countable Dense Homogeneous
Rodrigo Hernández-Gutiérrez, Michael Hrušák
We prove that if is a non-meager -filter, then both and are countable dense homogeneous spaces.
Spaces of Remote Points
Rodrigo Hernández-Gutiérrez, Michael Hrušák, Angel Tamariz-Mascarúa
Given a Tychonoff space , let be the set of remote points of . We view as a topological space. In this paper we assume that is metrizable and as…
Disconnectedness properties of Hyperspaces
Rodrigo Hernández-Gutiérrez, Angel Tamariz-Mascarúa
Let be a Hausdorff space and let be one of the hyperspaces , , or ( a positive integer) with the Vie…
A non-discrete space with Menger at infinity
Angelo Bella, Rodrigo Hernández-Gutiérrez
In a paper by Bella, Tokgös and Zdomskyy it is asked whether there exists a Tychonoff space such that the remainder of in some compactification is Menger but not -c…
