Noether-Type Symmetries and Associated Conservation Laws of Some Systems of Nonlinear PDEs

Jianqin Mei

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.
