Variational symmetries and Lagrangian multiforms

D. G. Sleigh, F. W. Nijhoff, V. Caudrelier

By considering the closure property of a Lagrangian multiform as a conservation law, we use Noether's theorem to show that every variational symmetry of a Lagrangian leads to a Lag…

A Variational Approach to Lax Representations

D. G. Sleigh, F. W. Nijhoff, V. Caudrelier

It is shown that the Zakharov-Mihailov (ZM) Lagrangian structure for integrable nonlinear equations derived from a general class of Lax pairs possesses a Lagrangian multiform struc…
