Generation by sections and $k$-ampleness

Algebraic Geometry 2016-07-25 v1

Abstract

In the article "Submanifold of abelian varieties", A.J. Sommese proved that direct sum and tensor product of two vector bundles EE and FF over a smooth projective variety are kk-ample if EE and FF are kk-ample and are generated by global sections. Here we show that the latter condition is not needed.
