Some remarks on cones of partially ample divisors

Algebraic Geometry 2016-02-17 v1

Abstract

We study the cones of q-ample divisors on smooth complex varieties. In favourable cases, we identify a part where the closure of this cone and the nef cone have the same boundary. This is especially interesting for Fano (or almost Fano) varieties.
