Path connectedness, local path connectedness and contractibility of $\mathcal{S}_c(X)$
Abstract
The hyperspace of all nontrivial convergent sequences in a Hausdorff space is denoted by . This hyperspace is endowed with the Vietoris topology. In connection with a question and a problem by Garc\'ia-Ferreira, Ortiz-Castillo and Rojas-Hern\'andez, concerning conditions under which is pathwise connected, in the current paper we study the latter property and the contractibility of . We present necessary conditions on a space to obtain the path connectedness of . We also provide some sufficient conditions on a space to obtain such path connectedness. Further, we characterize the local path connectedness of in terms of that of . We prove the contractibility of for a class of spaces and, finally, we study the connectedness of Whitney blocks and Whitney levels for .
