摘要：
Let R be a commutative noetherian graded ring. In R[Y-1 ,..., Y-m] we consider the linear forms a(i) = Sigma(m)(j=1)a(ji)Y(j), 1 <= i <= n, with a(ji) homogeneous elements of R. We state a necessary and sufficient condition, in terms of *grades of the determinantal ideals of the matrix A = (a(ji)), for the ideal (a(1), ... ,a(n)) to be a *complete intersection of *grade n in R[Y-1, ... , Y-m].
