Unstable products of smooth curves

Algebraic Geometry 2009-11-11 v3 Differential Geometry

Abstract

We give examples of smooth surfaces with negative first Chern class which are slope unstable with respect to certain polarisations, and so have Kahler classes that do not admit any constant scalar curvature Kahler metrics. We also compare this to the work of Song-Weinkove on the J-flow.
