Abstract
In order to show existence of solutions for linear elliptic problems with measure data, a first classical method, due to Stampacchia, is to use a duality argument (and a regularity result for elliptic problems). Another classical method is to pass to the limit on approximate solutions obtained with regular data (converging towards the measure data). A third method is presented. It consists to pass to the limit on approximate solutions obtained with numerical schemes such that Finite Element schemes or Finite Volume schemes. This method also works for convection-diffusion problems which lead to non coercive elliptic problems with measure data. Thanks to a uniqueness result, the convergence of the approximate solutions as the mesh size vanishes is also achieved.
