Exact String Theory Instantons by Dimensional Reduction
arXiv:hep-th/9311185 · doi:10.1016/0370-2693(94)90078-7
Abstract
We identify exact gauge-instanton-like solutions to (super)-string theory using the method of dimensional reduction. We find in particular the Polyakov instanton of 3d QED, and a class of generalized Yang-Mills merons. We discuss their marginal deformations, and show that for the $3d$ instanton they correspond to a dissociation of vector- and axial-magnetic charges.
