Abstract
We describe 2 non equivalent definitions of semiample vector bundles, and see how to obtain geometric characterizations when these notions are applied to the holomorphic cotangent bundle of a compact complex manifold. We relate these constructions to the finiteness of the fundamental group, and give a conjecture on compact complex manifolds with semiample cotangent bundle. This conjecture is related to some proven or conjectured statements when the manifold is Kähler or projective.
This is a joint work with Francesco Esposito.
