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 algebras completely fills the elliptic classes as well as some parabolic classes. Loop algebras of EN fill additional parabolic classes, and exotic finite algebras, hyperbolic extensions of EN and more general indefinite Lie algebras fill the hyperbolic classes. Since they correspond to brane configurations that cannot be… CONTINUE READING
