ABSTRACT
In this paper, we consider an approximation space I=(U,R).where U is non empty finite set and R is an arbitrary equivalence relation on U. We define the dominating set of the Rough zero divisor graph G(Z(T∗)) of the Rough Semiring T, where Z(T∗) denotes the set of nonzero zero divisor of T. We construct a minimal dominating set on T. We also prove that the domination number of G(Z(T∗)) is equal to the number of equivalence classes induced by R on U. We illustrate these concepts with suitable examples.
