Abstract
The Novikov equation and a negative flow of the Novikov hierarchy are related to a negative flow of the Sawada-Kotera hierarchy and the Sawada-Kotera equation by reciprocal transformations, respectively. With the help of the Darboux transformations for the negative flow of the Sawada-Kotera hierarchy, the Sawada-Kotera equation and reciprocal transformations, we obtain a parametric representation for N-soliton solutions to the Novikov equation and the negative flow of the Novikov hierarchy.
