In this paper, we study a generalization of group, hypergroup and n-ary group. Firstly, we define interval-valued fuzzy (anti fuzzy) n-ary sub-hypergroup with respect to a t -norm TT (t -conorm SS). We give a necessary and sufficient condition for, an interval-valued fuzzy subset to be an interval-valued fuzzy (anti fuzzy) n-ary sub-hypergroup with respect to a t -norm TT (t -conorm SS). Secondly, using the notion of image (anti image) and inverse image of a homomorphism, some new properties of interval-valued fuzzy (anti fuzzy) n -ary sub-hypergroup are obtained with respect to infinitely ∨∨-distributive t -norms TT (∧∧-distributive t -conorms SS). Also, we obtain some results of TT-product (SS-product) of the interval-valued fuzzy subsets for infinitely ∨∨-distributive t -norms TT (∧∧-distributive t -conorms SS). Lastly, we investigate some properties of interval-valued fuzzy subsets of the fundamental n -ary group with infinitely ∨∨-distributive t -norms TT (∧∧-distributive t -conorms SS).
