Abstract :
This paper deals with the generalized quasi-concavity based on triangular norms (t-norms) and applied to membership functions of fuzzy sets in n-dimensional Euclidean space. Necessary and sufficient conditions for this type of generalized quasi-concavity are derived, some examples demonstrating the concepts are presented and a possible application is discussed
