The spectral curve of the lens space matrix model

Following hep-th/0211098 we study the matrix model which describes the topological A-model on T*(S-3/Z(p)). We show that the resolvent has square root branch cuts and it follows that this is a p cut single matrix model. We solve for the resolvent and find the spectral curve. We comment on how this is related to large N transitions and mirror symmetry.
