Abstract
Let R be a commutative Noetherian (not necessary local) ring with identity and be a proper ideal of R. We introduce a notion of -relative system of parameters and characterize them by using the notion of cohomological dimension. Also, we present a criterion of relative Cohen-Macaulay modules via relative system of parameters.
