On the universality class of the conifold
David Berenstein
The possibility of having discrete degrees of freedom at singularities associated to `conifolds with discrete torsion' is studied. We find that the field theory of D-brane probes n…
Resolution of Stringy Singularities by Non-commutative Algebras
David Berenstein, Robert G. Leigh
In this paper we propose a unified approach to (topological) string theory on certain singular spaces in their large volume limit. The approach exploits the non-commutative structu…
The Standard Model on a D-brane
David Berenstein, Vishnu Jejjala, Robert G. Leigh
We present a consistent string theory model which reproduces the Standard Model, consisting of a D3-brane at a simple orbifold singularity. We study some simple features of the phe…
Observations on non-commutative field theories in coordinate space
David Berenstein, Robert G. Leigh
We discuss non-commutative field theories in coordinate space. To do so we introduce pseudo-localized operators that represent interesting position dependent (gauge invariant) obse…
