The limit as p→ ∞ in the eigenvalue problem for a system of p-Laplacians

Abstract

In this paper, we study the behavior as p→ ∞ of eigenvalues and eigenfunctions of a system of p-Laplacians, that is (Formula presented.) in a bounded smooth domain Ω. Here α+ β= p. We assume that α/p→Γ and β/p→1-Γ as p→ ∞ and we prove that for the first eigenvalue λ1,p we have (λ1,p)1/p→λ∞=1/maxx∈Ωdist(x,∂Ω).Concerning the eigenfunctions (up, vp) associated with λ1,p normalized by ∫Ω|up|α|vp|β=1, there is a uniform limit (u∞, v∞) that is a solution to a limit minimization problem as well as a viscosity solution to (Formula presented.) In addition, we also analyze the limit PDE when we consider higher eigenvalues.
