Abstract:

Let $Ω$ be a bounded Lipschitz domain of $\mathbb R^N$, $N\geq 2$. In this paper, we study the asymptotic behavior of the first Robin eigenvalue of the $p$-Laplace operator as $β$ goes to $0$ and as $β$ goes to $+\infty$, deriving sharp asymptotic expansions of the eigenvalue; the expansion in the Dirichlet limit $β\to+\infty$ is obtained under the additional assumption that $\partialΩ$ is of class $C^{1,1}$.
