- A construction of negative flows for integrable systems based on the Lax representation and squared eigenfunctions is proposed. Examples considered include the Boussinesq equation and its reduction to the Sawada-Kotera and Kaup-Kupershmidt equations; one of the Drinfeld-Sokolov systems and its reduction to the Krichever-Novikov equation.
