A Lower Bound for the Gradient of ∞-Harmonic Functions

We establish a lower bound for the gradient of the solution to1-Laplace equation in a strongly star-shaped annulus with capacity type boundary conditions. The proof involves properties of the radial derivative of the solution, so that starshapedness of level sets easily follows.
