【 摘 要 】

Residual intersection generalizes the notion of linkage. The central questions in residual intersection theory are: for a residual intersection J of I, when is R/J Cohen-Macaulay, and what is the canonical module for R/J? Our main result gives answers to the two central questions in the case where R is merely Cohen-Macaulay. (c) 2006 Elsevier Inc. All rights reserved.
