Evidence for Non-perturbative String Symmetries

arXiv:hep-th/9411178 · doi:10.1007/BF01872784

Abstract

String theory appears to admit a group of discrete field transformations -- called dualities -- as exact non-perturbative quantum symmetries. Mathematically, they are rather analogous to the better-known duality symmetries, which hold perturbatively. In this talk the evidence for duality is reviewed and some speculations are presented.
