"The first edition of this book has been the best introduction to difference equations available; the second edition improves this even further." --Martin Bohner, University of Missouri-Rolla

"The authors have their finger on the current trends in difference equations. This is a well-written textbook by authors who are known as teachers and expositors." --Johnny Henderson, Auburn University

Difference Equations, Second Edition offers a practical introduction to this important field of solutions for engineering and the physical sciences. Topic coverage includes discrete modeling, differential equations, combinatorics and numerical methods. A hallmark of this revision are the diverse applications to many subfields of mathematics.
