Symmetry properties of positive solutions of elliptic equations in an infinite sectorial cone*
Published online by Cambridge University Press: 14 November 2011
Synopsis
We prove symmetry properties of positive solutions of semilinear elliptic equations Δu + f(u) = 0 with Neumann boundary conditions in an infinite sectorial cone. We establish that any positive solution u of such equations in an infinite sectorial cone ∑α in ℝ3 is spherically symmetric if the amplitude α of ∑α is not greater than π.
