This monograph encompasses a selection of sixteen papers that have been awarded on the confer ence "Free Boundary difficulties: Numerical 7reatment and optimum Control", held on the Mathematisches Forschungsinstitut Oberwolfach, West Germany, July 9-15, 1989. It was once the purpose of the organizers of the assembly to compile specialists from various parts within the vast box of unfastened boundary difficulties, the place a definite emphasis was once given to the numerical remedy and optimum keep watch over of loose boundary difficulties. even though, through the convention additionally a host papers resulting in vital new theoretical insights have been provided. The robust connection among thought and functions reveals its mirrored image during this monograph which includes papers of excessive theoretical and numerical curiosity, in addition to functions to special sensible difficulties. a number of the contributions are keen on section transition phenomena, a box which was once of specific value throughout the assembly; themes like spinodal decomposition, form reminiscence alloys, crystal progress and stream via porous media are addressed. one other box of significant curiosity through the con ference was once fluid move; additionally this box is addressed during this quantity. the amount opens with a contribution via H. W. Alt and that i. Pawlow. of their paper the matter of spinodal decomposition is taken care of within the non-isothermal scenario. For the 1st time the lifestyles of a susceptible way to the corresponding process of evolution equations might be proved. the result of a few numerical experiments also are said. within the following paper, M. Bornert and I.
