The conservation law approach in geometric PDEs
Chang-Yu Guo, Chang-Lin Xiang
In this survey paper, we give an overview of the conservation law approach in the study of geometric PDEs that models in particular polyharmonic maps.

Global conservation law for an even order elliptic system with antisymmetric potential
Chang-Yu Guo, Chang-Lin Xiang, Gao-Feng Zheng
In this note, we refine the local conservation law obtained by Lamm-Rivière for fourth order systems and de Longueville-Gastel for general even order systems to a global conservati…
