Rough Fuzzy Hyperideals in Ternary Semihypergroups

الملخص EN

The relations between rough sets and algebraic systems have been already considered by many mathematicians, and rough sets have been studied in various kinds of algebraic systems.

This paper concerns a relationship between rough sets and ternary semihypergroups.

We introduce the notion of rough hyperideals and rough bi-hyperideals in ternary semihypergroups.

We also study fuzzy, rough, and rough fuzzy ternary subsemihypergroups (left hyperideals, right hyperideals, lateral hyperideals, hyperideals, and bi-hyperideals) of ternary semihypergroups.
