Difference Equations and Inequalities

A study of difference equations and inequalities. This second edition offers real-world examples and uses of difference equations in probability theory, queuing and statistical problems, stochastic time series, combinatorial analysis, number theory, geometry, electrical networks, quanta in radiation, genetics, economics, psychology, sociology, and other disciplines. It features 200 new problems, 400 additional references, and a new chapter on the qualitative properties of solutions of neutral difference equations. Preliminaries; linear initial value problems; miscellaneous difference equations; difference inequalities; qualitative properties of solutions of difference systems; qualitative properties of solutions of higher order difference equations; qualitative properties of solutions of neutral difference equations; boundary value problems for linear systems; boundary value problems for nonlinear systems; miscellaneous properties of solutions of higher order linear difference equations; boundary value problems for higher order difference equations; Sturm-Liouville problems and related inequalities; difference inequalities in several independent variables.
