Abstract

This paper introduces the notions of Λ-g★-closed sets and Λ-g★-open sets in interval-valued topological spaces. Basic properties and several characterizations of these sets are discussed. The connections between interval-valued Λ-g★-closed sets and other types of interval-valued generalized closed sets are also examined. In addition, a few important results concerning their behavior and structural properties are obtained. These newly defined sets extend the study of generalized closedness in interval-valued topology and provide further scope for investigation in this area.

1. Introduction

Motivated by these developments, in this paper we introduce the concepts of Λ-g★-closed sets and Λ-g★-open sets in interval-valued topological spaces. Several basic properties and characterizations of these newly defined sets are obtained. Moreover, the relationships between interval-valued Λ-g★-closed sets and other existing classes of interval-valued generalized closed sets are discussed. The results presented in this paper contribute to the further development of generalized structures in interval-valued topology and may provide a foundation for future investigations in this field.

This page shows an excerpt of the introduction. The full text, including the theorems, proofs and examples, is available in the PDF.
