Bridgeland Stability conditions on threefolds II: An application to Fujita's conjecture

Algebraic Geometry 2013-07-16 v2

Abstract

We apply a conjectured inequality on third chern classes of stable two-term complexes on threefolds to Fujita's conjecture. More precisely, the inequality is shown to imply a Reider-type theorem in dimension three which in turn implies that K_X + 6L is very ample when L is ample, and that 5L is very ample when K_X is trivial.
