Abstract
For a certain class of perturbations of the equation ut=f(u)uxut=f(u)ux, we prove the existence of change of coordinates, called quasi-Miura transformations, that reduce these perturbed equations to the unperturbed one. As an application, we propose a criterion for the integrability of these equations.
