Fano manifolds of index n-1 and the cone conjecture

Algebraic Geometry 2012-07-18 v1

Abstract

The Morrison-Kawamata cone conjecture predicts that the actions of the automorphism group on the effective nef cone and the pseudo-automorphism group on the effective movable cone of a klt Calabi-Yau pair (X,Δ)(X, \Delta) have finite, rational polyhedral fundamental domains. Let ZZ be an nn-dimensional Fano manifold of index n1n-1 such that KZ=(n1)H-K_Z = (n-1) H for an ample divisor HH. Let Γ\Gamma be the base locus of a general (n1)(n-1)-dimensional linear system VHV \subset |H|. In this paper, we verify the Morrison-Kawamata cone conjecture for the blow-up of ZZ along Γ\Gamma.
