The Gelfand Problem for the Infinity Laplacian

Abstract

We study the asymptotic behavior as p → ∞ of the Gelfand problem −Δpu = λeu in Ω ⊂ Rn, u = 0 on ∂Ω. Under an appropriate rescaling on u and λ, we prove uniform convergence of solutions of the Gelfand problem to solutions of min{|∇u|−Λeu, −Δ∞u} = 0 in Ω, u = 0 on ∂Ω. We discuss existence, non-existence, and multiplicity of solutions of the limit problem in terms of Λ
