Abstract
We consider D-branes on an orbifold and investigate the moduli space of the D-brane world-volume gauge theory by using toric geometry and gauged linear sigma models. For , we find that there are five phases, which are topologically distinct and connected by flops to each other. We also verify that non-geometric phases are projected out for cases as expected. Resolutions of non-isolated singularities are also investigated.
