Conservation laws of discrete Korteweg-de Vries equation

Abstract:
Three and five point conservation laws for discrete Korteweg-de Vries equations are found. For obtaining conservation laws we construct and solve the determining functional equation. Ee represent method for reducing possible functional equation to a system of partial differential equations.
