Abstract.
Using critical point theory, we study the existence of at least three solutions for perturbed nonlinear difference equations with discrete boundary-value condition depending on two positive parameters.
Keywords:
nonlinear difference equations, discrete boundary value problem, three solutions, critical point theory, variational methods.
