To expand slightly on the conclusion of this variational proof, note that $N_w(1)\ge N_u(1)=\gamma$ (again because $u$ minimizes the energy), so the condition that $N_w'(1)=0$ gives $0=\int_{\partial B_1}(|\nabla w|^2-2N_w(1)ww_\nu)-(n-2)\int_{B_1}|\nabla w|^2\le\int_{\partial B_1}(|\nabla w|^2-2\gamma ww_\nu)-(n-2)\int_{B_1}|\nabla w|^2$ (as $ww_\nu=\gamma w^2\ge 0$); the last quantity bounds from below $N_u'(1)$, so we get indeed $N_u'(1)\ge 0$. | |
