Symmetries and Integrability of Difference Equations de Peter A. Clarkson

Symmetries and Integrability of Difference Equations: London Mathematical Society Lecture Note Series, cartea 255

Peter A. Clarkson

Frank W. Nijhoff

There has in recent years been a remarkable growth of interest in the area of discrete integrable systems. Much progress has been made by applying symmetry groups to the study of differential equations, and connections have been made to other topics such as numerical methods, cellular automata and mathematical physics. This volume comprises state of the art articles from almost all the leading workers in this important and rapidly developing area, making it a necessary resource for all researchers interested in discrete integrable systems or related subjects.
