Abstract
We analyse D-branes on orbifolds with discrete torsion,
extending earlier results. We analyze certain abelian orbifolds of the
type 
3/Γ, where Γ is given by 
m × n,
for the most general choice of discrete torsion parameter. By
comparing with the AdS/CFT correspondence, we can consider different
geometries which give rise to the same physics. This identifies new
mirror pairs and suggests new dualities at large N. As a by-product
we also get a more geometric picture of discrete torsion.
