A note on radiality of solutions of P-laplacian

Abstract

In this note we consider the p-laplacian equation (see equation (1) below) in radial domains (a hall or all R^N). We prove that any positive solution of this equation, assuming suitable boundary data, is radial if it satisfies the additional condition u(x) < 0 if x < 0.
