Dirac-wave maps

  • Xiaoli HanEmail author


Motivated by supersymmetric field theories, we couple the nonlinear sigma model on 1 + 1-dimensional Minkowski space with a spinor field. The corresponding Lagrangian is \({\cal L} = \int_{R^{1 + 1}}\{\vert d\phi\vert^2 + \langle\psi,{D \hskip -2.4mm \slash}\psi\rangle\}\). The classical solutions of this model are called Dirac-wave maps. We prove that there exists a unique global solution for given Cauchy data.
