Abstract
Nakaoka and Oda ([1] and [2]) introduced the notion of maximal open sets and minimal closed sets in topological spaces. In this paper, we introduce new classes of sets called maximal θ-open sets, minimal θ-closed sets, θ-semi maximal open and θ-semi minimal closed and investigate some of their fundamental properties.
