We give characterizations for a subspace of a hyperspace, endowed with either the Vietoris or the Wijsman topology, to be compact or relatively compact. Then we characterize-both globally and at the single points-the local compactness of a hyperspace, endowed with either the Vietoris, the Wijsman, or the Hausdorff metric topology. Several examples illustrating the behaviour of local compactness are also included. © 2001 Elsevier Science B.V. All rights reserved.

Abstract
We give characterizations for a subspace of a hyperspace, endowed with either the Vietoris or the Wijsman topology, to be compact or relatively compact. Then we characterize-both globally and at the single points-the local compactness of a hyperspace, endowed with either the Vietoris, the Wijsman, or the Hausdorff metric topology. Several examples illustrating the behaviour of local compactness are also included. © 2001 Elsevier Science B.V. All rights reserved.File in questo prodotto:
