Query: Mean curvature flow with obstacles: existence, uniqueness and regularity
  of solutions   We show short time existence and uniqueness of $\C^{1,1}$ solutions to the
mean curvature flow with obstacles, when the obstacles are of class $\C^{1,1}$.
If the initial interface is a periodic graph we show long time existence of the
evolution and convergence to a minimal constrained hypersurface.
