Description
In the 1990, Moffatt discussed a dissipative model of
Magneto-hydrodynamics (that he called “magnetic relaxation” but could
also be called “Darcy” or “Stokes” MHD), in order to get stationary
solutions of the Euler equations with prescribed topology. We will
discuss the corresponding PDEs and some concepts of generalized
solutions related both to P.-L. Lions’ dissipative solutions to the
Euler equations and to the recent approach by Ambrosio, Gigli and
Savare of the heat equation in general metric spaces.
