Gauss curvature flos of entire graphs We study entire graphs in Euclidean space that evolve with normal velocity equal to a power of the Gau\ss{} curvature. Mild restrictions on the initial data ensure that smooth solutions exist for all positive times. For initial data close to cones, we obtain stability results. This is joint work with John Urbas. |
