Mori Dream Spaces as fine moduli of quiver representations
Abstract
We construct Mori Dream Spaces as fine moduli spaces of representations of bound quivers, thereby extending results of Craw--Smith \cite{CrawSmith} beyond the toric case. Any collection of effective line bundles on a Mori Dream Space defines a bound quiver of sections and a map from to a toric quiver variety called the multigraded linear series. We provide necessary and sufficient conditions for this map to be a closed immersion and, under additional assumptions on , the image realises as the fine moduli space of -stable representations of the bound quiver. As an application, we show how to reconstruct del Pezzo surfaces from a full, strongly exceptional collection of line bundles.
