| Resumo | |
In a recent communication Ibragimov introduced the concept of nonlinearly self-adjoint differential equation {[}Ibragimov NH. Nonlinear self-adjointness and conservation laws. J Phys A Math Theor 2011; 44: 432002 (8pp.)]. In this paper a nonlinear self-adjoint classification of a general class of fifth-order evolution equation with time dependent coefficients is presented. As a result five subclasses of nonlinearly self-adjoint equations of fifth-order and four subclasses of nonlinearly self-adjoint equations of third-order are obtained. From the Ibragimov's theorem on conservation laws {[}Ibragimov NH. A new conservation theorem. J Math Anal Appl 2007; 333: 311-28] conservation laws for some of these equations are established.
