报告摘要：

The authors consider Prandtl-type equations obtained from an incompressible MHD system with a non-slip boundary condition on the velocity and perfectly conducting condition on the magnetic field. Assuming that the initial tangential component of the magnetic field is not zero, local-in-time existence and uniqueness of solutions is obtained for the nonlinear MHD boundary layer equations. Unlike the case of the classical Prandtl equations, no monotonicity condition on the tangential velocity is required. This confirms mathematically that the magnetic field has a physical stabilizing effect for the MHD boundary layer.
