Abstract

The concept of a (δ,β) irresolute function in topological spaces is introduced and studied. Some of their characteristic properties are considered. We also investigate the relationships between these classes of functions and other classes of non-continuous functions.

Keywords

topological spaces; δ-semiopen sets; β-closed sets; (δ; β)-irresolute and β-irresolute functions
