摘要:

LetIbe an ideal of a Noetherian ringRand let S be a multiplicatively closed subset of R. The purpose of this paper is to compare the topologies defined by the integral filtration {Īn}n≥0and the (S)-symbolic filtration {S(In)}n≥0 using the natural homomorphisms between the local cohomology groups {H0q(R÷In)}n≥0 and {H0q(R÷Īn)}n≥0.
