Abstract
We introduce and study two new notions of sets called (Λ, mn)-closed sets and gΛ mn -sets, which are defined on a nonempty set with two minimal structures. These sets enables us to unify modifications of λ-closed sets [1] and generalized Λ-sets [15], respectively. Moreover, we give a new characterization of the class of mn-T 1/2 [17] by using gΛ mn -sets.
