Details | Quasi-soclc ideals, that is, the ideals I of the form I = Q: m^q in a Noetherian local ring (A, m) with the Gorenstein tangent cone G(m) are explored, where q ≥ 1 is an integer and Q is a parameter ideal of A generated by monomials of a system x_1, x_2,..., x_d of elements in A such that (x1, x2,..., xd)is a reduction of m. The questions of when I is integral over Q and of when the graded rings G(I) and F (I) are Cohen-Macaulay are answered. Criteria for G(I) and R(I) to be Gorenstein rings are given. © 2009, Rocky Mountain Mathematics Consortium. All rights reserved. |
