Abstract : The two dimensional steady laminar boundary layer of an incompressible medium at a wall is treated. For a given approximate solution of the Prandtl equation error bounds are computed with the aid of parabolic inequalities. Also bounds for the wall shear stress, for the displacement thickness, for the momentum loss thickness and for the energy loss thickness are given. The bounds converge toward zero if the residual error and the initial error of the approximation both vanish. (Author)
