Abstract

In this chapter we study the general theory of linear difference equations, as well as direct methods for solving equations with constant coefficients, which give the solution in a closed form. In Section 1 general concepts about grid equations are introduced. Section 2 is devoted to the general theory of mth order linear difference equations. In Section 3 methods for solving constant-coefficient equations are considered, and in Section 4 these methods are used to solve second-order equations. Solving grid eigenvalue problems for the simplest difference operators is discussed in Section 5.
