Query: Liouville-type theorems for the planer stationary MHD equations with
  growth at infinity   For the two dimensional stationary MHD equations, we proved that Liouville
type theorems hold if the velocity is growing at infinity, where the magnetic
field is assumed to be bounded under a smallness condition. The key point is to
overcome the nonlinear terms, since no maximum principle holds for the MHD case
with respect to the Navier-Stokes equations.
