Applications of rough sets to Gamma-hyperideals in left almost Gamma-semihypergroups
The relations between rough sets and algebraic systems have been already considered by many mathematicians. This article concerns the relationship between rough sets and left almost Gamma-semihypergroups. In this article, using Pawlak idea, the properties of lower and upper approximations of sub LA-Gamma-semihypergroup (respectively Gamma-hyperideal, bi-Gamma-hyperideal and interior Gamma-hyperideal) are investigated.
