Galilei-invariant higher-order equations of burgers and korteweg-de vries types
We describe nonlinear Galilei-invariant higher-order equations of Burgers and Korteweg-de Vries types. We study symmetry properties of these equations and construct new nonlinear extensions for the Galilei algebra AG(1, 1).
