Abstract: We discuss how matrix factorizations offer a practical method of computing the quiver and associated superpotential for a hypersurface singularity. This method also yields explicit geometrical interpretations of Dbranes (i. e., quiver representations) on a resolution given in terms of Grassmannians. As an example we analyze some nontoric singularities which are resolved by a single ℙ 1 but have "length" greater than one. These examples have a much richer structure than conifolds. A picture is proposed that relates matrix factorizations in LandauGinzburg theories to the way that matrix factorizations are used in this paper to perform noncommutative resolutions. © 2012 SpringerVerlag.
