| dc.description.abstract | We introduce a notion of ampleness for subschemes of any codimension
using the theory of q-ample line bundles. We also investigate certain geometric
properties satisfied by ample subvarieties, e.g. the Lefschetz hyperplane
theorems and numerical positivity. Using these properties, we also construct a
counterexample to the converse of the Andreotti-Grauert vanishing theorem. | |
