Modified motion by mean curvature: local existence and uniqueness and qualitative properties. (English) Zbl 0994.35053

The authors study free boundary problems for modified motions by mean curvature, giving also examples of singular limits of some phase transition models. They prove an existence and uniqueness result for a time-local solution. They also give some properties of behaviors of the solutions.
