In the present paper we study the relationship between and the possible topologies T on X which realize the continuity of f with respect to the Vietoris topology on F2(X) generated by T.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Hyperspaces topologySelectionMonotone selectionOrdered spaceSelections and order-like relationsArtÃculo2017-05-3010.4995/agt.2001.2150Abierto1989-4147
