Abstract:
We study the regularity properties of viscosity solutions to a class of degenerate normalized $p-$Laplace type equations. In particular, we prove that the gradient of viscosity solutions is H\{o}lder continuous, and we give the optimal exponent. Moreover, we also show that viscosity solutions to equations with very general degeneracy laws are differentiable.
