Abstract
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 c onstruction of the integrals of motion. The procedure is applied to th e nonlinear difference equation and to the q-wave equations in D = 3 a nd D = 4.
