DOWNLOAD EBOOKLet omega be a smooth bounded subset of (R sup N) and L be a uniformly elliptic second order differential operator with smooth coefficients. The author obtains a bound for the difference between the solution, u, to the equation Lu = f in omega with the Dirichlet boundary conditions: u = 0 on boundary omega, and the solution, u prime, to corresponding boundary value problem on a non-smooth domain omega prime which appriximates omega. The magnitude of the bound depends only on the Euclidean distance between the domains omega and omega prime. (Author).
