Abstract

In this paper, we introduce two operators associated with ψ* and *ψ operators in ideal topological
spaces and discuss the properties of these operators. We give further
characterizations of Hayashi-Samuel spaces with the help of these two
operators. We also give a brief discussion on homeomorphism of generalized
closure spaces which were induced by these two operators.

Keywords

ideal topological spaces Hayashi-Samuel space isotonic spaces homeomorphism Δ-operator ∇-operator
