The Strength of String Nonperturbative Effects and Strong-Weak Coupling Duality
arXiv:hep-th/9304129 · doi:10.1142/S0217732393002397
Abstract
A strong-weak coupling duality symmetry of the string equations of motion has been suggested in the literature. This symmetry implies that vacua occur in pairs. Since the coupling constant is a dynamical variable in string theory, tunneling solutions between strong and weak coupling vacua may exist. Such solutions would naturally lead to nonperturbative effects with anomalous coupling dependence. A highly simplified example is given.
