Abstract

For a given continuum XX and a natural number n,n, we consider the hyperspace Fn(X)F_n(X) of all nonempty subsets of XX with at most nn points, metrized by the Hausdorff metric. In this paper we show that if XX is a dendrite whose set of end points is closed, nNn \in \mathbb{N} and YY is a continuum such that the hyperspaces Fn(X)F_n(X) and Fn(Y)F_n(Y) are homeomorphic, then YY is a dendrite whose set of end points is closed.
