Brief discussions on T-level complex fuzzy subgroup

Abstract

In this article, we combine complex fuzzy set and fuzzy subgroups. We introduce the notion of T-level complex fuzzy subgroups, step complex fuzzy subgroups and study fundamental properties. Also the basic operations like union, intersection, product, Cartesian product of two complex fuzzy subgroups are studied. Furthermore, we define a T-level subset and T-level subgroups and then some of their properties are studied.
