Narain, R.; Kara, A. H. On the redefinition of the variational and ‘partial’ variational conservation laws in a class of nonlinear PDEs with mixed derivatives. (English) Zbl 1272.76185 Math. Comput. Appl. 15, No. 4, 732-741 (2010). This paper is concerned with symmetry generators and conservation laws for some higher-order PDEs with mixed derivatives. The properties displayed by the resultant conserved quantities are highlighted for certain fluid flows. Reviewer: V. D.
