Some Aspects of Approximation of Optimal Control Problems for Systems Governed by Parabolic Problemntrol. A problem with non-negative “specific heat” coefficient is considered. The existence of a weak solution to this problem is shown, uniqueness and stability results are presented. For a class of related typical optimal control problems results concerning existence of optimal controls are given.

The Method of Minimizing the Defects for the Stefan Problem,sional degenerate Stefan problem. The method consists in approximating the unknown temperature distribution as well as the unknown phase change interface by members of linear function spaces in such a way that the arising defects become minimal. This approach leads to an approximation problem the nu
