Abstract

Two nonlinear σ models are discussed which have N=2 supersymmetry in four dimensions. The first is globally supersymmetric on a noncompact field manifold. The second model involves a compact maniflod and requires coupling to N=2 supergravity for consistency. Upon reduction to three and two dimensions, both models have N=4 supersymmetry. In addition, the global model has vanishing (one-loop) charge renormalization in two dimensions.
