Abstract

Theory of rough sets is an important tool in data mining. In this paper, we are initiating the study of roughness in hemirings with respect to the Pawlak approximation space and also with respect to the generalized approximation space. Lower and upper rough subhemirings and ideals are studied. Lower and upper approximations of k-ideals and h-ideals of a hemiring are discussed.
