Abstract
Since the initiation of generalized closed set, it played a pivotal role in the study of various topological structures. Recently in the bitopological environment, the concept of \(g^*\)-closed set is extended to strongly \(g^*\)-closed set and interrelationships were established among various closed sets, viz. \(sg^*\)-closed set, g-closed set, \(g^*\)-closed set, j-closed set. In this treatise, our main aim is to study a stronger form generalized closed set via \(\gamma \)-open set and to characterize the proposed notion in the same space. As application of the concept, separation axioms on a bitopological space is explored in the light of \(\gamma \)-open sets.
