Uniform stability of the ball with respect to the first Dirichlet and Neumann $\infty -$eigenvalues

Joao V. da Silva, Julio D. Rossi, Ariel M. Salort

In this note we analyze how perturbations of a ball ${\mathfrak{B}}_r\subset {\mathbb{R}}^n$ behaves in terms of their first (non-trivial) Neumann and Dirichlet $\infty -$eigenvalues w…
