Intuitionistic (α, β)- Fuzzy Hv-Subgroups

Atanassov introduced the notion of intuitionistic fuzzy sets as a generalization of the notion of fuzzy sets. In this paper we introduce the concept of an intuitionistic (α β, ) -fuzzy Hv-subgroups of an Hv-groups by using the notion of “belongingness (∈) ” and “quasi-coincidence (q) ” of fuzzy points with fuzzy sets, where α ∈ ∈{ , , q} β ∈ ∈ ∈∨ ∈ ∧ { , , , q q q} and, then we investigate the basic properties of these notions.
