On a class of difference equations involving a linear map with two dimensional kernel
We establish necessary and sufficient conditions for the existence of periodic solutions to second-order nonlinear difference equations of the form $\Delta^2x_i+\lambda x_i+\Delta f(x_i)=e_i$, $i\in{\mathbb N}$, and for a simpler equation with difference-free nonlinearity. The linear part of the eq...
