Chern-Simons from Dirichlet 2-brane instantons
arXiv:hep-th/9601179 · doi:10.1016/0370-2693(96)00851-9
Abstract
In the vicinity of points in Calabi-Yau moduli space where there are degenerating three-cycles the low energy effective action of type IIA string theory will contain significant contributions arising from membrane instantons that wrap around these three-cycles. We show that the world-volume description of these instantons is Chern-Simons theory.
