Abstract
The notions of mn- -closed sets and mn- spaces in an ideal bi m-space are introduced and investigated by Sanabria et al. [18]. In this paper, we introduce the notion of (Λ,mn*)-closed sets and obtain a decomposition of n*-closed sets and a characterization of mn- spaces [18] by using mn- -closed sets and (Λ,mn*)-closed sets.
