Abstract: In this work, given p∈(1,∞), we prove the existence and simplicity of the first eigenvalue λp and its corresponding eigenvector (up,vp), for the following local/nonlocal PDE system (0.1)−Δpu+(−Δ)pru=2αα+βλ|u|α−2|v|βuin Ω−Δpv+(−Δ)psv=2βα+βλ|u|α|v|β−2vin Ωu=0on RN∖Ωv=0on RN∖Ω, where Ω⊂RN is a bounded open domain, 0<r,s<1 and α(p)+β(p)=p. Moreover, we address the asymptotic limit as p→∞, proving the explicit geometric characterization of the corresponding first ∞-eigenvalue, namely λ∞, and the uniformly convergence of the pair (up,vp) to the ∞-eigenvector (u∞,v∞). Finally, the triple (u∞,v∞,λ∞) verifies, in the viscosity sense, a limiting PDE system.
