D-branes on Singularities: New Quivers from Old
David Berenstein, Vishnu Jejjala, Robert G. Leigh
In this paper we present simplifying techniques which allow one to compute the quiver diagrams for various D-branes at (non-Abelian) orbifold singularities with and without discret…
Non-Commutative Calabi-Yau Manifolds
David Berenstein, Robert G. Leigh
We discuss aspects of the algebraic geometry of compact non-commutative Calabi-Yau manifolds. In this setting, it is appropriate to consider local holomorphic algebras which can be…
Non-Commutative Moduli Spaces, Dielectric Tori and T-duality
David Berenstein, Vishnu Jejjala, Robert G. Leigh
We review and extend recent work on the application of the non-commutative geometric framework to an interpretation of the moduli space of vacua of certain deformations of N=4 supe…
Marginal and Relevant Deformations of N=4 Field Theories and Non-Commutative Moduli Spaces of Vacua
David Berenstein, Vishnu Jejjala, Robert G. Leigh
We study marginal and relevant supersymmetric deformations of the N=4 super-Yang-Mills theory in four dimensions. Our primary innovation is the interpretation of the moduli spaces…
Discrete Torsion, AdS/CFT and duality
David Berenstein, Robert G. Leigh
We analyse D-branes on orbifolds with discrete torsion, extending earlier results. We analyze certain Abelian orbifolds of the type C^3/ Γ, where Γis given by Z_m x Z_n, for the mo…
