Abstract [en] : In this Paper we study the adjoint symmetries for a class of third-order evolution equations in (1+1) dimensions. We assume that the equations admit adjoint symmetries of maximum order 2, and we obtain the complete classification with respect to this property. Examples of adjoint symmetries and integrating factors for the Korteweg-de Vries and the Schwarzian-Korteweg-de Vries equations are given.
