Abstract Let G=(V, E) be a locally finite graph, Ω⊂ V be a bounded domain, Δ be the usual graph Laplacian, and λ 1 (Ω) be the first eigenvalue of− Δ with respect to Dirichlet boundary condition. Using the mountain pass theorem due to Ambrosetti–Rabinowitz, we prove that if α< λ 1 (Ω), then for any p> 2, there exists a positive solution to {− Δ u− α u=| u| p− 2 u in Ω∘, u= 0 on∂ Ω, where Ω∘ and∂ Ω denote the interior and the boundary of Ω respectively. Also we consider similar problems involving the p-Laplacian and poly-Laplacian by the same method. Such problems can be viewed as discrete versions of the Yamabe type equations on Euclidean space or compact Riemannian manifolds.
