Abstract :
Past implementations of the Generalized Method of Moments utilized nonsmooth functions in current approximation bases that were difficult to integrate accurately. Herein we devise a method for defining arbitrarily smooth functions on polygonal GMM subdomains using Schwarz-Christoffel conformal mapping. The resulting functions are much smoother, and can be integrated more accurately using numerical quadrature.
