Abstract

This paper is concerned with the introduction of a new notion of closed maps namely, Δ^{∗}-closed maps using Δ^{∗}-closed sets and the analysis of their significant properties in topological spaces. Also the nature of Δ^{∗}-closed maps under composition mappings and their applications are explored in this paper.

Keywords

Δ^{∗}-closed sets, Δ^{∗}-continuous map, Δ^{∗}-irresolute map, δg-irresolute map, _{Δ^{∗}}T_{δ}-space and _{Δ^{∗}}T_{δg^{∗}}-space
