概要	This paper explores the structure of quasi-socle ideals I = Q : m2 in a Gorenstein local ring A, where Q is a parameter ideal and m is the maximal ideal in A. The purpose is to answer the problems as to when Q is a reduction of I and when the associated graded ring G (I) = {N-ary circled plus operator}n ≥ 0 In / In + 1 is Cohen-Macaulay. Wild examples are explored. © 2007 Elsevier Ltd. All rights reserved.
