Some generalized forms of fuzzy interval valued hyperideals in a hyperring

Some generalized forms of the hyperideals of a hyperring in the paper of zhan et al. (2008) will be given. as a generalization of the interval valued (α,β) -fuzzy hyperideals of a hyperring with α,β ε { ε,q,ε ∧ q,ε ∨ q } and α ≠ ε ∧ q,the notion of generalized interval valued (α,β) -fuzzy hyperideals of a hyperring is also introduced. special attention is concentrated on the interval valued (ε γ,ε γ ∨ q δ ) -fuzzy hyperideals. as a consequence,some characterizations theorems of interval valued (ε γ,ε γ ∨ q δ ) -fuzzy hyperideals will be provided. © 2014 hongjie li et al.
