Throughout, let A be a (commutative Noetherian) local ring (with identity) of dimension d> 0, having maximal ideal m. For an m-primary ideal q of A, we shall denote the multiplicity of q by e (q) or eA (q); if x1,..., Xd fOrIn a system of parameters (‘s. 0. p.’will be used as an abbreviation for ‘system of parameters’, and ‘ss 0. p.’will stand for ‘subset of a system of parameters’) for A, we shall use 4x1,.... xd) to denote e (Cy,, AXi). The length of an A-module M will be denoted by I (M) or I,(M).It is well known that, for an m-primary ideal q, for all large values of the positive integer n, the expression [(A/q”) takes the same values as a rational polynomial in n of degree d having leading coefficient e (q)/d!, so that
