Abstract

Let X be a Fano manifold of dimension n and index n-3. Kawamata proved the
non vanishing of the global sections of the fundamental divisor in the case
n=4. Moreover he proved that if Y is a general element of the fundamental
system then Y has at most canonical singularities. We prove a generalization of
this result in arbitrary dimension.
