The Gelfand problem for the Infinity Laplacian

Analysis of PDEs 2021-12-20 v1

Abstract

We study the asymptotic behavior as pp\to\infty of the Gelfand problem Δpu=λeu in ΩRn,u=0 on Ω. -\Delta_{p} u=\lambda\,e^{u}\ \textrm{in}\ \Omega\subset\mathbb{R}^n,\quad u=0 \ \textrm{on}\ \partial\Omega. Under an appropriate rescaling on uu and λ\lambda, we prove uniform convergence of solutions of the Gelfand problem to solutions of min{uΛeu,Δu}=0 in Ω,u=0 on Ω. \min\left\{|\nabla{}u|-\Lambda\,e^{u}, -\Delta_{\infty}u\right\}=0\ \textrm{in}\ \Omega,\quad u=0\ \text{on}\ \partial\Omega. We discuss existence, non-existence, and multiplicity of solutions of the limit problem in terms of Λ\Lambda.
