Resumen en inglés An ideal on a set X is a nonempty collection of subsets of X with heredity property which is also closed finite unions. The concept of ideal m-spaces was introduced by Al-Omari and Noiri [1]. In this paper, we introduce and study an operator Ψ∗ : P(X) → M defined as follows for every A ∈ X, Ψ∗(A) = {x ∈ X : there exists a U ∈ M(x) such that U − A ∈ I}, and observes that Ψ∗(A) = X − (X − A)∗
