Categorical properties on the hyperspace of nontrivial convergent sequences
S. Garcia-Ferreira, R. Rojas-Hernandez, Y. F. Ortiz-Castillo
In this paper, we shall study categorial properties of the hyperspace of all nontrivial convergent sequences of a Freéch-Urysohn space , this hyperspace is eq…
Characterizing Corson and Valdivia compact spaces
F. Casarrubias-Segura, S. García-Ferreira, R. Rojas-Hernández
We give a new characterization of Valdivia compact spaces: A compact space is Valdivia if and only if it has a dense commutatively monotonically retractable subspace. This result s…
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 (-skeletons) having certain rich properties. By using monotonically retractable spaces we solve a que…
