Abstract
We use some basic results from the theory of variational methods to prove the exisetnce and uniqueness of periodic solutions to second-order nonlinear discrete problems. Our method has no continuous counterpart since it is based on the finite dimension of the corresponding function space. Our main tools include matrix theory and the Fundamental theorem of calculus for Lebesgue Integral.
