Research Abstract |
The objective in this study is to understand the deformation process of free boundaries from variational and geometric viewpoint. To this end, some free boundary problems appearing in two phenomena : solid-liquid phase transition ; ferromagnetic thin film ; were dealt with. On that basis, various study results were reported during the research period. Especially, it will be notable that some obtained results are concerned with more advanced themes than originally expected : optimal control problem ; numerical experiments for optimal controls.
