Partially ample line bundles on toric varieties
journal contribution
posted on 2015-07-13, 13:09 authored by Nathan Broomhead, John C. Ottem, Artie PrendergastArtie PrendergastAmple line bundles are a fundamental concept in algebraic geometry, encapsulating the
central notion of positivity. A natural extension of the notion of ampleness is that of q-
ampleness, for nonnegative integers q. Roughly speaking, q-ample line bundles on a variety
are those which \kill cohomology in degrees above q." Line bundles of this kind have
been studied by a number of authors, including Andreotti{Grauert [AG], Sommese [Som],
Demailly{Peternell{Schneider [DPS], and Totaro [Tot].
