Abstract
In this chapter we describe main motivating factors for the investigation of symplectic difference systems in this book. This motivation comes from several sources, mainly from (i) a generalization of the theory of second-order Sturm-Liouville difference equations, (ii) discrete variational analysis, (iii) (classical and discrete) Hamiltonian mechanics, (iv) discrete analogy of the theory of linear Hamiltonian differential systems, and (v) numerical methods for Hamiltonian differential systems preserving the symplectic structure.
