DOI: https://doi.org/10.62072/acm.2022.050202

AbstractWe introduce the notions of nano L*-perfect, nano R*-perfect, and nano C*-perfect sets in ideal nano spaces and study their properties. We obtained a characterization for compatible ideals via nano R*-perfect sets and and investigate further their important properties

On S-closed sets and semi S-closed in nano topological spaces

N. Sekar, A. Pandi and I. Rajasekaran*

Annals of Communications in Mathematics 2022,

5 (1),

55-62

DOI: https://doi.org/10.62072/acm.2022.050105

ABSTRACT.In this article, we focus on nano \( \mathcal{S} \)-closed sets and nano \( \mathcal{S}_{\delta} \)-closed sets are introduced and study. Also, we introduce and study nano \( \mathcal{S} \)-continuous functions and nano \( \mathcal{S}_{\delta} \)-continuous functions. Furthermore, we introduce the notions of nano topological spaces called nano \( \mathcal{S}\text{-}T_{1/2} \) space and nano \( \mathcal{S}\text{-}T_{5} \) space.

On Interval-Valued Λ-Sets and 𝜆-Closed Sets via Kernel Operators

O. Nethaji and I. Rajasekaran*

Annals of Communications in Mathematics 2026,

9(2),

In Press

ABSTRACT.In this study, we investigate specific kernel structures within interval valued topological spaces. We introduce the notions of interval-valued Λ-sets and interval-valued λ-closed sets and discuss their essential properties. The connections between these concepts and existing notions in interval-valued topology are examined in detail. Various characterizations and foundational results are presented to clarify their structural behavior. This work aims to enhance and extend the theoretical framework of interval-valued topology.
