Let n, m ∈ N with m ≤ n and X be a metric continuum. We consider the hyperspaces Cn(X) (respectively, Fn(X)) of all nonempty closed subsets of X with at most n components (respectively, n points). The (n, m)−fold hyperspace suspension on X was

In this paper we prove that the property of a continuum of being determined by the positive Whitney levels of its hyperspace of subcontinua characterizes the dendrites whose set of endpoints is closed in the class of dendrites. This answers a questio

For a metric continuum X and a positive integer n, we consider the n-th symmetric product F n ( X ) of all nonempty subsets of X with at most n points, with the Hausdorff metric. In this paper we prove for an almost meshed locally connected continuum

For a metric continuum X and a positive integer n , we consider the hyperspaces C n ( X ) (respectively, F n ( X ) ) of all nonempty closed subsets of X with at most n components (respectively, n points). Let HS n ( X ) be the quotient space C n ( X

Let Y be a metric continuum. Let C n ( Y ) be the hyperspace of nonempty closed subsets of Y with at most n components. In this paper we show that if X is a dendrite with closed set of end points and C 2 ( X ) is homeomorphic to C 2 ( Y ) , for some

General theorems concerning s -connectedness and hyperspaces are first obtained. These results are applied to prove that: for a continuum X having zero surjective semispan, (1) each Whitney block in the hyperspace of subcontinua of X , C ( X ), has t

Let $X$ be a metric continuum and $n$ a positive integer. Let $F_{n}(X)$ be the hyperspace of all nonempty subsets of $X$ with at most $n$ points, metrized by the Hausdorff metric. We said that $X$ has unique hyperspace $F_n(X)$ provided that, if $Y$

For a continuum X we denote by C ( X ) the hyperspace of subcontinua of X, metrized by the Hausdorff metric. Let D be the class of dendrites whose set of end points is closed and let LD be the class of local dendrites X such that every point of X has
