Abstract

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 Sc(X)\mathcal{S}_c(X) of a space XX. We answer some questions in \cite{sal-yas} and generalize several results in \cite{may-pat-rob}. We prove that: The connectedness of XX implies the connectedness of Sc(X)\mathcal{S}_c(X); the local connectedness of XX is equivalent to the local connectedness of Sc(X)\mathcal{S}_c(X); and the path-wise connectedness of Sc(X)\mathcal{S}_c(X) implies the path-wise connectedness of XX. We also show that the space of nontrivial convergent sequences on the Warsaw circle has c\mathfrak{c}-many path-wise connected components, and provide a dendroid with the same property.
