The hyperbolic n-space as a graph in euclidean (6n-6)-space.
The inverse mean curvature flow and -harmonic functions
We consider the level set formulation of the inverse mean curvature flow. We establish a connection to the problem of -harmonic functions and give a new proof for the existence of weak solutions.
