Atanassov's intuitionistic (S, T)-fuzzy n-ary sub-hypergroups and their properties

摘要

In this paper, we define a new kind of intuitionistic fuzzy n-ary sub-hypergroups of an n-ary hypergroup. This definition, which is based on Atanassov's intuitionistic fuzzy sets. t-norms and t-conorms, includes earlier definitions of (n-ary) sub-hypergroups, (intuitionistic) fuzzy (n-ary) sub-hypergroups. Then some related properties are investigated. Also, intuitionistic fuzzy relations with respect to t-norms and t-conorms on n-ary hypergroups are discussed. (c) 2008 Elsevier Inc.
