The authors investigate symplectic difference equations, depending on a real parameter. These equations are considered together with self-adjoint boundary conditions. Different types of oscillation theorems are obtained. The main result is an oscillation theorem that relates the number of eigenvalues to the number of generalized zeros of solutions.
