D-branes in Nonabelian Orbifolds with Discrete Torsion
Tamas Hauer, Morten Krogh
We study IIB string theory on the orbifold R^8/Gamma with discrete torsion where Gamma is an arbitrary subgroup of U(4). We extend some previously known identities for discrete tor…

Uncovering Infinite Symmetries on [p,q] 7-branes: Kac-Moody Algebras and Beyond
Oliver DeWolfe, Tamas Hauer, Amer Iqbal +1
In a previous paper we explored how conjugacy classes of the modular group classify the symmetry algebras that arise on type IIB [p,q] 7-branes. The Kodaira list of finite Lie alge…

Uncovering the Symmetries on [p,q] 7-branes: Beyond the Kodaira Classification
Oliver DeWolfe, Tamas Hauer, Amer Iqbal +1
We begin a classification of the symmetry algebras arising on configurations of type IIB [p,q] 7-branes. These include not just the Kodaira symmetries that occur when branes coales…
