We study phase structure of the moduli space of a D0brane on the orbifold C 3 /Z2 × Z2 based on stability of quiver representations. It is known from an analysis using toric geometry that this model has multiple phases connected by flop transitions. By comparing the results of the two methods, we obtain a correspondence between quiver representations and geometry of toric resolutions of the orbifold. It is shown that a redundancy of coordinates arising in the toric description of the Dbrane moduli space, which is a key ingredient of disappearance of nongeometric phases, is understood from the monodromy around the orbifold point. We also discuss why only geometric phases appear from the viewpoint of stability of D0branes.

In this paper we present simplifying techniques which allow one to compute the quiver diagrams for various Dbranes at (nonAbelian) orbifold singularities with and without discrete torsion. The main idea behind the construction is to take the orbifold of an orbifold. Many interesting discrete groups fit into an exact sequence N → G → G/N. As such, the orbifold M/G is easier to compute as (M/N)/(G/N) and we present graphical rules which allow fast computation given the M/N quiver.
