Abstract

We study toric singularities of the form of C-4/Gamma for finite abelian groups Gamma subset of SU(4). In particular, we consider the simplest case Gamma = Z(2) x Z(2) x Z(2) and find explicitly charge matrices for partial resolutions of this orbifold by extending the method by Morrison and Plesser. We obtain three kinds of algebraic equations, z(1)z(2)z(3)z(4) = z(5)(2),z(1)z(2)z(3) = z(4)(2)z(5) and z(1)z(2)z(5) = z(3)z(4) where z(i)'s parametrize C-5. When we put N D1 branes at this singularity, it is known that the field theory on the worldvolume of N D1 branes is T-dual to 2 x 2 x 2 brane cub model. We analyze geometric interpretation for field theory parameters and moduli space.
