AMPLE SUBVARIETIES AND q-AMPLE DIVISORS
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.
متن کاملAmple Weil Divisors on K 3 Surfaces with Du Val Singularities Valery Alexeev
0.3. For the singular Q-Fanos one can try to use the same approach. The first difference is that, if X has a non-Gorenstein singularity, then locally in a neighborhood of such a point a general element of I-Kxl should have Du Val singularity. The second observation is that -Kx, restricted on S, is not a Cartier divisor any more but only a Weil divisor such that its multiple is an ample Cartier ...
متن کاملGeometric invariant theory based on Weil divisors
Given an action of a reductive group on a normal variety, we construct all invariant open subsets admitting a good quotient with a quasiprojective or a divisorial quotient space. Our approach extends known constructions like Mumford’s Geometric Invariant Theory. We obtain several new Hilbert-Mumford type theorems, and we extend a projectivity criterion of Bia lynicki-Birula and Świȩcicka for va...
متن کاملA view on extending morphisms from ample divisors
The philosophy that “a projective manifold is more special than any of its smooth hyperplane sections” was one of the classical principles of projective geometry. Lefschetz type results and related vanishing theorems were among the typically used techniques. We shall survey most of the problems, results and conjectures in this area, using the modern setting of ample divisors, and (some aspects ...
متن کاملAmple Divisors on Moduli Spaces of Pointed Rational Curves
We introduce a new technique for proving positivity of certain divisor classes on M0,n and its weighted variants M0,A. Our methods give a complete description of the models arising in the Hassett’s log minimal model program for M0,n.
