Singularities which occur in the solution of a partial differential equation due to sharp corners in the boundary tend to produce inaccuracies near the singularity, which sometimes may also propagate into the solution domain, for any standard method of obtaining this solution. In this paper it is sh

In this paper, we present a method to solve numerically the time-dependent Maxwell equations in nonsmooth and nonconvex domains. Indeed, the solution is not of regularity H 1 (in space) in general. Moreover, the space of H 1 -regular fields is not dense in the space of solutions. Thus an H 1 -confor

In this paper, the variational iteration method (VIM) is used to study a nonlinear singular boundary value problems arising in various physical equations. The VIM overcomes the singularity issue at the origin x = 0. The Lagrange multipliers for all four cases of the boundary value problems are forma
