An introduction to difference equations

de Saber Elaydi, Saber N. Elaydi

"This book integrates both classical and modern treatments of difference equations. It contains the most updated and comprehensive material on stability, Z-transform, discrete control theory, asymptotic theory, continued fractions, and orthogonal polynomials. Yet the presentation is simple enough for the book to be used by advanced undergraduate and beginning graduate students in mathematics, engineering science, and economics. Moreover, scientists and engineers who are interested in discrete mathematical models will find it useful as a reference."--BOOK JACKET.
