(λ,μ)‎-Fuzzy Version of Ideals, Interior Ideals, Quasi-Ideals, and Bi-Ideals

الملخص EN

We introduced (λ,μ)-fuzzy ideals, (λ,μ)-fuzzy interior ideals, (λ,μ)-fuzzy quasi-ideals, and (λ,μ)-fuzzy bi-ideals of an ordered semigroup and studied them.

When λ=0 and μ=1, we meet the ordinary fuzzy ones.

This paper can be seen as a generalization of Kehayopulu and Tsingelis (2006), Kehayopulu and Tsingelis (2007), and Yao (2009).
