Abstract:
We study toric singularities of the form of \C^4/\Ga for finite abelian groups \Ga \subset SU(4). In particular, we consider the simplest case \Ga=\Z_2 \times \Z_2 \times \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, and where 's parametrize \C^5. When we put D1 branes at this singularity, it is known that the field theory on the worldvolume of D1 branes is T-dual to brane cub model. We analyze geometric interpretation for field theory parameters and moduli space.- membrane model
