摘要：
We derive the conservation laws for a wide class of discrete equations, including the q-deformations of classical field-theoretic equations. The explicit expressions for the conserved currents are used in the construction of the integrals of motion. The procedure is applied to the nonlinear difference equation and to the q-wave equations in D = 3 and D = 4.
