Xiaolong Xin, Juntao Wang, Xiaohong Zhang · Journal of Intelligent & Fuzzy Systems · 2016
The main goal of this paper is to investigate set valued homomorphisms on hyperrings and construct popularized lower and upper approximations operators via them. Also, we put forth the concept of generalized lower and upper approximations respect to a hyperideals of hyperrings. The results of this paper can be regards as generalizations of related results in generalized lower and upper approximations in rings, which is introduced by Yamak.
