A guide to methods and results in a new area of application of Lie groups to difference equations, difference meshes (lattices), and difference functionals, this book focuses on the preservation of complete symmetry of original differential equations in numerical schemes. This symmetry preservation results in symmetry reduction of the difference model along with that of the original partial differential equations and in order reduction for ordinary difference equations.\u003c\/p\u003e\u003cp\u003eA substantial part of the book is concerned with conservation laws and first integrals for difference models.

Besides the well-explained theoretical background and motivations, there is also a large number of concrete examples discussed in reasonable details. Due to the fairly broad introductory part, the book is indeed self-contained. The main ideas and concepts appear understandable not only to experts.\u003cbr\u003e—Vojtech Zadnik, \u003cem\u003eZentralblatt MATH\u003c\/em\u003e 1236\u003c\/p\u003e\u003cp\u003eIn recent years \"difference geometry\" and its applications to integrable systems and mathematical physics have attracted significant attention and this monograph will contribute to the ongoing developments in this general area.
