In this paper, we define the dominant set, zero divisor of the rough semiring (T,Δ). Also We prove that RS(X) is not a zero divisor for a dominant set X U where U is the finite universal set on the set of all rough sets for the given information system together with the operations praba Δ and praba . We illustrate these concepts through examples. © 2015 Academic Publications, Ltd.

In this paper, we give a characterization of the rough semiring (T, Δ , ∇). The order of a rough semiring is also derived. We present the idea of rough homomorphism on the set of all rough sets for the given information system together with the operations Praba Δ and Praba ∇. We illustrate these concepts through examples. © 2017, African Mathematical Union and Springer-Verlag Berlin Heidelberg.
