内容摘要：Quantum fieldtheory has developed models with intricate and subtle geometric structure, likethe supersymmetric nonlinear sigma model or the superstring model. We have turnedthese models into geometric variational models. The resulting Euler-Lagrangeequations are coupled nonlinear systems of elliptic equations that presentnovel challenges for geometric analysis. Forsolve them, the underlying symmetries，inparticular conformal invariance, play a key role.
