Abstract (2. Language): 
In this paper, a new kind of sets called generalized -closed (briefly g -closed) sets are introduced and studied in a topological space by using the concept of operation on topological space. The class of all g -closed sets is strictly larger than the class of all -closed sets. Some of their properties are investigated here. Finally, some characterizations of g -regular and g -normal spaces have been given.
