Moduli of quiver representations for exceptional collections on surfaces
Abstract
Suppose is a smooth projective surface over an algebraically closed field , is a full strong exceptional collection of line bundles on . Let be the quiver associated to this collection. One might hope that is the moduli space of representations of with dimension vector for a suitably chosen stability condition : . In this paper, we show that this is the case for del Pezzo surfaces. Furthermore, we show the blow-up at a point can be recovered from an augmentation of exceptional collections (in the sense of L. Hille and M.Perling) via morphism between moduli of quiver representations.
