Some adjunction properties of ample vector bundles

Algebraic Geometry 2007-05-23 v1

Abstract

Let EE be an ample vector bundle of rank rr on a projective variety XX with only log-terminal singularities. We consider the nefness of adjoint divisors KX+(tr)det(E)K_X+(t-r)det(E) when t>=dim(X)t>=dim(X) and t>rt>r. As a corollary, we classify pairs (X,E)(X,E) with crc_r-sectional genus zero.
