Abstract

The main goal of this paper is to study some new classes of sets by using the open sets and functions in topological spaces. For this aim, the notions of τ*-open, τ-τ*-α-open, τ-τ*-preopen, τ-τ*-semiopen, τ-τ*-b-open, τ-τ*-β-open, τ*-τ-α-open, τ*-τ-preopen, τ*-τ-semiopen, τ*-τ-b-open, τ*-τ-β-open, τ*-α-open, τ*-preopen, τ*-semiopen, τ*-bopen and τ*-β-open sets are introduced. Properties and the relationships of τ*-open sets are investigated. Finally, the relationships between these sets and the related concepts are investigated.
