Abstract
We establish necessary and sufficient conditions for the existence of periodic solutions to second-order nonlinear difference equations of the form ∆ 2xi + λxi + ∆f(xi) = ei , i ∈ N, and for a simpler equation with difference-free nonlinearity. The linear part of the equation has two-dimensional kernel.
