The Journal of Difference Equations and Applications presents state-of-the-art papers on difference equations and the academic, pure and applied problems in which they arise. The journal is composed of original research, expository and review articles, and papers that present novel concepts in application and techniques. Contributions may be related to applications of difference equations in non-linear dynamics, chaos theory, complex dynamics, mathematical biology, discrete control theory, oscillation theory, integrable systems, functional equations, special functions and orthogonal polynomials, numerical analysis, combinatorics, computational linear algebra, and other fields and specialties at the editors' discretion.
