The series of International Conferences on Difference Equations and Applications has established a tradition within the mathematics community. Scientists from many different areas of research come together to highlight current interests, challenges and unresolved problems. This volume comprises selected papers presented at the Sixth International Conference on Difference Equations which was held at Augsburg, Germany. It covers all themes in the fields of discrete dynamical systems and ordinary and partial difference equations, classical and contemporary, theoretical and applied. It provides a useful reference text for graduates and researchers working in this area of mathematics.
