Abstract
In this paper we define the concept of a fuzzy clique. In the case of a fuzzy graph the concept of a cycle and a fuzzy cycle has been studied. Aim of this paper is to present the concept of a clique and a fuzzy clique in fuzzy graphs consistent with the definition of cycles and fuzzy cycles in fuzzy graphs. Various interesting properties of fuzzy cliques are presented. A complete characterization of the structure of the fuzzy clique is also presented.
