On delta-Semiopen Sets And A Generalization Of Functions

Abstract

In this paper, we introduce and investigate a weaker form of R-mapsand delta-continuous functions which is called almost delta-semicontinuity. We obtain its characterizations, its basic properties and their relationships with other types offunctions between topological spaces.
