Conservation laws of partial differential equations: Symmetry, adjoint symmetry and nonlinear self-adjointness
Zhi-Yong Zhang
Nonlinear self-adjointness method for constructing conservation laws of partial differential equations (PDEs) is further studied. We show that any adjoint symmetry of PDEs is a dif…

Determination of approximate nonlinear self-adjointenss and approximate conservation law
Zhi-Yong Zhang
Approximate nonlinear self-adjointness is an effective method to construct approximate conservation law of perturbed partial differential equations (PDEs). In this paper, we study…

Approximate nonlinear self-adjointness and approximate conservation laws
Zhi-Yong Zhang
In this paper, approximate nonlinear self-adjointness for perturbed PDEs is introduced and its properties are studied. Consequently, approximate conservation laws which cannot be o…
