A characterization of nef and good divisors by asymptotic multiplier ideals

Algebraic Geometry 2010-09-21 v1

Abstract

A characterization of nef and good divisors is given: a divisor D on a smooth complex projective variety is nef and good if and only if the asymptotic multiplier ideals of sufficiently high multiples of e(D) D$ are trivial, where e(D) denotes the exponent of the divisor D. Some results of the same kind are proved in the analytic setting.
