**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.
