On δ-preregular e*-open sets in topological spaces

Abstract

In this paper, we introduce a new class of sets called, δ-preregular e*-open sets and investigate their properties and characterizations. By using δ-preregular e*-open sets, we obtain decompositions of complete continuity and decompositions of perfect continuity.
