Abstract

We present a well-controlled perturbative renormalization-group treatment of superconductivity from short-ranged repulsive interactions in a variety of model two-dimensional electronic systems. Our analysis applies in the limit where the repulsive interactions between the electrons are small compared to their kinetic energy.
