This paper studies the question of when the associated graded ring I = nβ₯0 I n /I n+1 of a certain ideal I in a local ring is Gorenstein. The main result implies, for example, that if A is a regular local ring, is a prime ideal in A with dim A/ = 2, and A/ is a complete intersection in codimension o
Let R be a local CohenαMacaulay ring, let I be an R-ideal, and let G be the associated graded ring of I. We give an estimate for the depth of G when G fails to be CohenαMacaulay. We assume that I has a small reduction number and sufficiently good residual intersection properties and satisfies local
Let I be an α-primary ideal in a Buchsbaum local ring A, α . In this paper, we investigate the Buchsbaum property of the associated graded ring of I when the equality I 2 s α I holds for some minimal reduction α of I. However, the Buchsbaum property does not always follow even if I 2 s α I. So we gi
