A new weaker form of δ - Closed set in Topological Spaces

In this paper a new class of generalized closed sets called δsg*-closed sets in topological spaces using g-closed sets are introduced and studied. Moreover the relations between δsg-closed sets and already existing various closed sets are analysed. δsg*-closed set is independent of g -closed set and weaker than δg*-closed set. The class of δsg*-closed sets is properly placed between the classes of δg*-closed sets and # gsclosed sets and a chain of relations is proved as follows.
