Abstract:Dirac-harmonic maps with curvature term is a geometric variational model originated in the supersymmetric nonlinear sigma model, the Euler-Lagrange equation couples a system of second order elliptic PDE/ODEs and a Dirac equation, both of them are nonlinear. In this talk, we will present recent results on the existence and uniqueness of the solutions.
