Symmetry and convexity of level sets of solutions to the infinity Laplace's equation
Electronic journal of differential equations, Tome 1998 (1998)
We consider the Dirichlet problem $-\Delta_\infty u=f(u)$ in $\Omega, u=0$ on $\partial\Omega$ where $\Delta_\infty u = u_{x_i}u_{x_j}u_{x_ix_j}$ and f is a nonnegative continuous function. We investigate whether the solutions to this equation inherit geometrical properties from the domain $\Omega$. We obtain results concerning convexity of level sets and symmetry of solutions.
