New characterizations of some existing classes of generalized closed sets and topological spaces are given. A new class of generalized closed sets are introduced.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Nodecqr-closedExtremally disconnectedGeneralized closed sets: a unified approachArtÃculo2017-05-3010.4995/agt.2001.2148Abierto1989-4147
