Abstract: | In this paper we consider viscosity equilibria to the mean curvature level set flow with a Dirichlet condition. The main result
shows that almost every level set of an equilibrium solution is analytic off of a singular set of Hausdorff dimension at most
n − 8 and that these level sets are stationary and stable with respect to the area functional. A key tool developed is a maximum
principle for solutions to obstacle problems where the obstacle consists of (viscosity) minimal surfaces. Convergence to equilibrium
as t → ∞ is also established for the associated initial-boundary value problem. |
