August undefined, 2024

WebThe concept of g -closedness of sets in topological spaces was first initiated by Levine [ 1] using the closure operator. Since then this concept has been investigated extensively by many topologists. They have started defining new types of generalized closed sets without paying attention that those sets happen to be equivalent. WebA topology T for X is a collection of subsets of X such that ∅, X ∈ T, and T is closed under arbitrary unions and finite intersections. We say (X, T) is a topological space. Members …
