This book covers the basic elements of difference equations and the
tools of difference and sum calculus necessary for studying and
solv ing, primarily, ordinary linear difference equations. Examples
from various fields are presented clearly in the first chapter,
then discussed along with their detailed solutions in Chapters 2-7.
The book is in tended mainly as a text for the beginning
undergraduate course in difference equations, where the
"operational sum calculus" of the di rect use of the discrete
Fourier transforms for solving boundary value problems associated
with difference equations represents an added new feature compared
to other existing books on the subject at this introductory level.
This means that in addition to the familiar meth ods of solving
difference equations that are covered in Chapter 3, this book
emphasizes the use of discrete transforms. It is an attempt to
introduce the methods and mechanics of discrete transforms for solv
ing ordinary difference equations. The treatment closely parallels
what many students have already learned about using the opera
tional (integral) calculus of Laplace and Fourier transforms to
solve differential equations. As in the continuous case, discrete
operational methods may not solve problems that are intractable by
other meth ods, but they can facilitate the solution of a large
class of discrete initial and boundary value problems. Such
operational methods, or what we shall term "operational sum
calculus," may be extended eas ily to solve partial difference
equations associated with initial and/or boundary value problems."
