Finite-energy harmonic maps from R2 into simple manifolds such as CP1 ≅ S2 or SU(2)≅ S3 are thoroughly understood. The relevant equations constitute an integrable system, the general solution of which can be written down explicitly. Such solutions ma... Read More about Sigma models in 2+1 dimensions.
