Multiple Solutions for a Nonlinear Discrete Fourth Order p-Laplacian Equation
In this paper we study the existence of multiple solutions for a nonlinear discrete fourth order $p$-Laplacian equation. Similar kind of problems appears in some models from population biology. The proof of the main results is based on the three critical points theorem due to B. Ricceri. An example is given.
We obtain criteria for the existence of three solutions for the following fourth order problem ...
