Enhanced gauge symmetries on elliptic K3
arXiv:hep-th/9807057 · doi:10.1016/S0370-2693(99)00295-6
Abstract
We show that the geometry of K3 surfaces with singularities of type A-D-E contains enough information to reconstruct a copy of the Lie algebra associated to the given Dynkin diagram. We apply this construction to explain the enhancement of symmetry in F and IIA theories compactified on singular K3's.
