Commutative Algebra
Scientific paper
This article studies the behaviour under liaison of the deficiency modules of
schemes that are not assumed to be Cohen-Macaulay. Our study uses in particular
a generalization of Serre duality, and gives a satisfactory description of this
behaviour in dimension at most three. On the way we show other properties of
linked schemes.
