Harnack inequalities and Bôcher-type theorems for conformally invariant fully nonlinear degenerate elliptic equations

Abstract: We give a generalization of a theorem of B^ocher for the Laplace equation to a class of conformally invariant fully nonlinear degenerate elliptic equations. We also prove a Harnack inequality for locally Lipschitz viscosity solutions and a classification of continuous radially symmetric viscosity solutions.
