The Nonperturbative Gauge Coupling of N=2 Supersymmetric Theories
arXiv:hep-th/9806234 · doi:10.1016/S0370-2693(98)01235-0
Abstract
We argue that the topology of the quantum coupling space and the low energy effective action on the Coulomb branch of scale invariant N=2 SU(n) gauge theories pick out a preferred nonperturbative definition of the gauge coupling up to non-singular holomorphic reparametrizations.
