ABSTRACT
Let
be a smooth complex projective variety of dimension
. A notion
of geometric genus
for ample vector bundles
of rank
on
admitting some regular sections is introduced. The following inequality
holds:
. The question of characterizing equality is
discussed and the answer is given for
decomposable of corank 2. Some
conjectures suggested by the result are formulated.
