Numerical character of the effectivity of adjoint line bundles

Algebraic Geometry 2010-06-29 v5

Abstract

In this note we show that given a lc pair (X,Δ)(X, \Delta), a large enough multiple of the bundle KX+ΔK_X+ \Delta is effective provided that its Chern class contains an effective \bQ\bQ-divisor.
