In this paper, we prove the existence of at least three non- trivial solutions to nonlinear discrete boundary value problems { -△p,wu(x) + V(x)|u(x)|q-2u(x) = f(x; u(x)), x ∈ S, u(x) = 0, x ∈ ∂S, involving the discrete p-Laplacian on simple, finite and connected graphs S(S ∪ ∂S,E) with weight ω, where 1 < q < p < ∞. The approach is based on a suitable combine of variational and truncations methods.
