Characterizations of $e^\star$-open sets and nearby open sets on Infra topological spaces

Résumé

The study of infra-topological spaces focuses on characterizations of $e^\star$-open sets and nearby open sets in infra-topological spaces. The $e^\star$-open sets, a variation of open sets, are explored for their unique properties and relationships within the infra-topological framework. Additionally, nearby open sets, which capture the notion of points being close to each other, are investigated to provide a comprehensive understanding of the topological structure. The research aims to contribute to the broader field of topology by extending traditional concepts to infra-topological spaces, offering new perspectives on openness and proximity. The findings not only deepen our understanding of mathematical structures but also open avenues for applications in various scientific and engineering disciplines.
