Let I be an ideal of a Noetherian ring R and let S be a multiplicative
ly closed subset of R. The purpose of this paper is to study the relat
ionship between some properties of the associated, graded ring Gr(I, R
), and the comparison of the topologies defined by the I-adic filtrati
on {I-n}(n greater than or equal to>0), the integral filtration {I-n}(
n greater than or equal to 0), and the (S)-symbolic filtration {S(l(n)
)}(n greater than or equal to 0).
