Abstract: In this paper we discuss various refinements and generalizations of a theorem of Sankar Dutta and Paul Roberts. Their theorem gives a criterion for $ d$ elements in a $ d$-dimensional Noetherian Cohen-Macaulay local ring to be a system of parameters, i.e., to have height $ d$. We chiefly remove the assumption that the ring be Cohen-Macaulay and discuss similar theorems.
