Abstract : Group theoretical approach to study of symmetry properties, local conservation laws and inverse problem of variations is applied for a wide class of nonlinear partial differential equations. For the equations of the class the correspondence between symmetries and local conserved currents is established. Many interesting equations belong to the class, e.g. regularized long-wave equation, nonlinear diffusion equation and Navier-Stokes equations. A number of important differential identities was derived and shown to determine symmetry-related characteristics of differential systems.
