D-branes on Orbifolds and Topology Change

Abstract

We consider D-branes on an orbifold C3/ZnC^3/Z_n and investigate the moduli space of the D-brane world-volume gauge theory by using toric geometry and gauged linear sigma models. For n=11n=11, 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 n=7,9,11n=7,9,11 cases as expected. Resolutions of non-isolated singularities are also investigated.
