Strong comparison principle for p-harmonic functions in Carnot-Caratheodory spaces

Strong comparison principle for p-harmonic functions in Carnot-Caratheodory spaces

We extend Bony's propagation of support argument to C^1 solutions of the nonhomogeneous subelliptic p-Laplacian associated to a system of smooth vector fields satisfying Hörmander's finite rank condition. As a consequence we prove a strong maximum principle and strong comparison principle...

description We extend Bony's propagation of support argument to C^1 solutions of the nonhomogeneous subelliptic p-Laplacian associated to a system of smooth vector fields satisfying Hörmander's finite rank condition. As a consequence we prove a strong maximum principle and strong comparison principle that generalize results of Tolksdorf.
