Nonsmooth Data Error Estimates,mplies that optimal order convergence takes place for positive time even for nonsmooth initial data. We also show some other results which elucidate the relation between the convergence of the finite element solution and the regularity of the exact solution.

Maximum-Norm Stability and Error Estimates,re complicated than for those in the ..-norm of our earlier chapters, and will be carried out by a weighted norm technique. For the error estimates we need to do some auxiliary work in .. with . large.

Single Step Fully Discrete Schemes for the Inhomogeneous Equation,then apply our results to the spatially discrete equation. In view of the work in Chapter 7 for the homogeneous equation with given initial data, we restrict ourselves here to the case that the initial data vanish.

Multistep Backward Difference Methods,hen the method is stable and has a smoothing property analogous to that of single step methods of type IV. We shall use these properties to derive both smooth and nonsmooth data error estimates. In the end of the chapter we shall also discuss the use of two-step backward difference operators with variable time steps.

Affirming the Absurd in Harold Pinter guarantee that no loss occurs in the order of accuracy compared to the basic procedure in which the systems are solved exactly. For a successful iterative strategy it is also important to make a proper choice of the starting approximation at each time step.
