Conservation laws of some 'high-order' nonlinear PDEs using variational and 'partial-variational' principles
The construction of conserved vectors using Noether's theorem via a knowledge of a Lagrangian (or via the recently developed concept of partial Lagrangians) is well known. The formulae to determine these for higher-order °ows is some- what cumbersome and becomes more so as the order increase...
