CHARACTERIZATIONS OF SOME GENERALIZED OPEN SETS

K. Thanalakshmi*

Abstract


We discuss the properties of δ– preopen sets and the relations of δ– preclosure and δ– preinterior operators with the closure and interior operators of some well known generalized topologies. Also, we characterize regular open sets, δ– open sets, semiopen sets, preopen sets, b– open sets and β– open sets.

Keywords


δ– preopen, δ– open, semiopen, preopen, b– open and β– open sets, δ– preclosure and δ– preinterior.
