Webis in H1/2(Ω) then piecewise constant solutions of the discontinuous Galerkin method will converge to certain “weak” solutions (the definition of a weak solution in [13] is not standard). Below we exploit the evolution structure of the equation in an essential fashion. This allows us to avoid any smoothness assumptions on vwith respect to the
