Discrete fourth-order boundary value problems with four parameters

Critical point approaches for discrete anisotropic Kirchhoff type problems

“…The study of discrete boundary value problems has captured special attention in the last years. The modelling of certain nonlinear problems from biological neural networks, economics models, optimal control and other areas of study have led to the rapid development of the theory of difference equations; see [3,7,8,13,18,20,21,26]. For example, Gao [8] has studied…”

“…and has discussed the existence of positive solutions by means of the Rabinowitzs bifurcation theorem. In [13] the existence of multiple solutions were investigated using critical point theorems for the following discrete fourth-order boundary value problem…”
