Neuman and second boundary value problems for Hessian and Gauss curvature flows
Knut Smoczyk and Oliver Schnürer
We consider the flow of a strictly convex hypersurface driven by the Gauss curvature. For the Neumann boundary value problem and for the second boundary value problem we show that such a flow exists for all times and converges eventually to a solution of the prescribed Gauss curvature equation. We also discuss oblique boundary value problems and flows for Hessian equations
