Resumen de On the Lorenz gauge
Although edge elements satisfactorily solve the eddy current problem, formulations allowing the use of standard, node-based elements, are still looked for. But ``well-posed'' formulations have been elusive up to now. We propose one, based on a particular gauge, div ÿ2v, close to the ``Lorenz gauge'' of several recent publications, but not identical if one does not assume a piecewise uniform conductivity.
