... 15 moving plane procedure from the right and find a corresponding λ r 0 ≥ 0. If λ r 0 > 0, an analogue to Theorem 1.1 shows that u and v are symmetric with respect to the hyperplane x 1 = λ r 0 . ... u 0 (x) ≤ u(x) and v 0 (x) ≤ v(x) for all x ∈ Σ 0 . From above we can conclude u and v are symmetric with respect to the plane x 1 = 0. We perform this moving plane procedure taking planes pe...
