Abstract
Let u be a function on locally finite connect graph G = (V, E) and Ω be a bounded subset of V. We consider the nonlinear Dirichlet boundary condition problem
Let f: ℝ → ℝ be a function satisfying certain assumptions. Then under the functional framework we use the three-solution theorem and the variational method to prove that the above equation has at least three solutions, of which one is trivial and the others are strictly positive.
