Abstract: We show how enhanced gauge symmetry in type II string theory compactified on a CalabiYau threefold arises from singularities in the geometry of the target space. When the target space of the type IIA string acquires a genus g curve C of AN1 singularities, we find that an SU (N) gauge theory with g adjoint hypermultiplets appears at the singularity. The new massless states correspond to solitons wrapped about the collapsing cycles, and their dynamics is described by a twisted supersymmetric gauge theory on C × R4. We reproduce this result from an analysis of the Sdual Dmanifold. We check that the predictions made by this model about the nature of the Higgs branch, the monodromy of period integrals, and the asymptotics of the oneloop topological amplitude are in agreement with geometrical computations. In one of our examples we find that the singularity occurs at strong coupling in the heterotic dual proposed by Kachru and Vafa.
