Countable Dense Homogeneity and the Double Arrow Space

Rodrigo Hernández-Gutiérrez

Let $A$ denote the Alexandroff-Urysohn double arrow space. We prove the following results: (a) $A \times^{ω} 2$ is not countable dense homogeneous; (b) ${}^ω{\mat…

Non-meager $P$ -filters are Countable Dense Homogeneous

Rodrigo Hernández-Gutiérrez, Michael Hrušák

We prove that if $F$ is a non-meager $P$ -filter, then both $F$ and $^{ω} F$ are countable dense homogeneous spaces.

Spaces of Remote Points

Rodrigo Hernández-Gutiérrez, Michael Hrušák, Angel Tamariz-Mascarúa

Given a Tychonoff space $X$ , let $ϱ (X)$ be the set of remote points of $X$ . We view $ϱ (X)$ as a topological space. In this paper we assume that $X$ is metrizable and as…

The Ellis semigroup of a nonautonomous discrete dynamical system

S. García-Ferreira, M. Sanchis

We introduce the {\it Ellis semigroup} of a nonautonomous discrete dynamical system $(X, f_{1, \infty})$ when $X$ is a metric compact space. The underlying set of this semigroup is t…

Connectedness like properties on the hyperspace of convergent sequences

S. Garcia-Ferreira, R. Rojas-Hernandez

This paper is a continuation of the work done in \cite{sal-yas} and \cite{may-pat-rob}. We deal with the Vietoris hyperspace of all nontrivial convergent sequences $\mathcal{S}_c(X…

Families of continuous retractions and function spaces

S. Garcia-Ferreira, R. Rojas-Hernandez

In this article, we mainly study certain families of continuous retractions ( $r$ -skeletons) having certain rich properties. By using monotonically retractable spaces we solve a que…

Iterates of dynamical systems on compact metrizable countable spaces

S. García-Ferreira, Y. Rodriguez-López, C. Uzcátegui

Given a dynamical system $(X, f)$ , we let $E (X, f)$ denote its Ellis semigroup and $E (X, f)^{*} = E (X, f) ∖ {f^{n} : n \in N}$ . We analyze the Ellis semigroup of a dynam…
