Abstract

This paper deals with an approximation space and a hypergroup theory. Also we introduce invertible subhypergroup nano topology. Moreover, the notion of a normal and closed subhypergroup gives the characterization of invertible subhypergroup nano topology. Finally, we have shown that copper has same crystalline form but different chemical composition using nano homeomorphic in invertible subhypergroup nano topology.

Keywords and Phrases
