Paths in hyperspaces

Camillo Costantini and Wieslaw Kubi\'s

We prove that the hyperspace of closed bounded sets with the Hausdorff topology, over an almost convex metric space, is an absolute retract. Dense subspaces of normed linear spaces are examples of, not necessarily connected, almost convex metric spaces. We give some necessary conditions for the path-wise connectedness of the Hausdorff metric topology on closed bounded sets. Finally, we describe properties of a separable metric space, under which its hyperspace with the Wijsman topology is path-wise connected.
