Abstract

This paper is regarding the continuation of solutions to the Novikov equation beyond wave breaking. Our method is based on the characteristic of establishing new variables, then we transform the Novikov equation to a closed semilinear system on these new variables so that all singularities are resolved due to possible wave breaking. Returning to the original variables, we obtain a semigroup of global dissipative solutions, which depends continuously on the initial data. Note that the nonlinearity of the Novikov equation is higher than the Camassa–Holm equation; this requires us to seek the high-order energy density and another conservative law.
