Enriching Reider's Theorem for Surfaces with Stability Conditions |
Abstract |
Reider’s Theorem is a remarkably precise criterion for very ampleness of line bundles of the form K_S + D on an algebraic surface. By using Bridgeland stability conditions and various theorems about the moduli spaces of stable objects, we can extract information about the birational geometry of the blow-up of the projective space |K_S + D|^vee along the surface, analogous to results of Thaddeus in the curve case. This is part of a program that I am working on with my graduate students in Utah and Macri’s laboratory in Paris. |
