Formulas for multiplier ideals on singular varieties

Algebraic Geometry 2007-05-23 v2 Commutative Algebra

Abstract

We prove a generalization of Demailly-Ein-Lazarsfeld's subadditivity formula and Mustata's summation formula for multiplier ideals to the case of singular varieties, using characteristic pp methods. As an application of our formula, we improve Hochster-Huneke's result on the growth of symbolic powers of ideals in singular affine algebras.
