Abstract: Conservation law plays a very important role in many geometric variational problems and related elliptic systems. In this note, we refine the conservation law obtained by Lamm-Rivière for fourth order systems and de Longueville-Gastel for general even order systems.

Key words: conservation law, Uhlenbeck's gauge transform, even order elliptic system, antisymmetric potential, weak compactness
