A fully nonlinear equation of Grad Plasma type
The Grad Plasma Dynamics Equation has the form \(Δ u (x) = H ( | \{ u > u(x)\} |)\) and was introduced as a simplified way to describe the magnetization of plasma in a Tokamak. We explore several related equations of non-variational, fully nonlinear type.
