ON SOME NEW MAXIMAL AND MINIMAL SETS VIA θ-OPEN SETS Caldas, Miguel; Jafari, Saeid; Moshokoa, Seithuti P.;
Nakaoka and Oda ( and ) 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 -open sets, minimal -closed sets, -semi maximal open and -semi minimal closed and investigate some of their fundamental properties.
