| Abstract: | The algorithm for constructing conservation laws of Euler-Lagrange-type equations via Noether-type symmetry operators associated with partial Lagrangian has been presented. As applications, many new conservation laws of some important systems of nonlinear partial differential equations have been obtained. |
| Keywords: | Lie-Backlund Noether-type symmetries conservation law coupled integrable dispersionless equations coupled wave equations |
