Boundary value problems for functional difference equations on infinite intervals
Advances in Difference Equations volume 2006, Article number: 031283 (2006)
A general method for solving boundary value problems associated to functional difference systems on the discrete half-line is presented and applied in studying the existence of positive unbounded solutions for a system of two coupled nonlinear difference equations. A further example, illustrating the method, completes the paper.
