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. A set might be open, closed, both, or neither. In particular, open and closed sets are not mutually exclusive, meaning that it is in general possible for a subset of a topological space to simultaneously be both an open subset and a closed subset. Such subsets are known as clopen sets. Explicitly, a subset of a topological space is called clopen if both and its complement are open subsets of ; or equivalently, if and Web12 de dez. de 2013 · An open-closed set is also called a closed-open set or clopen set. The correspondence between Boolean algebras and inductively zero-dimensional compact Hausdorff spaces is known as Stone duality or Stone topological duality. song on the verge
