Abstract:

We extend the symmetry result of Serrin \cite{S} and Weinberger \cite{W} from the Laplacian operator to the highly degenerate game-theoretic $p$-Laplacian operator and show that viscosity solutions of $-\Delta _p^Nu=1$ in $\Omega$, $u=0$ and $\tfrac {\partial u}{\partial \nu }=-c\neq 0$ on $\partial \Omega$ can only exist on a bounded domain $\Omega$ if $\Omega$ is a ball.
