Uniqueness of quasimonochromatic breathers for the generalized Korteweg-de Vries and Zakharov-Kuznetsov models

Jorge Faya, Pablo Figueroa, Claudio Muñoz +1

Consider the generalized Korteweg-de Vries (gKdV) equations with power nonlinearities $q=2,3,4\dots$ in dimension $N=1$, and the Zakharov-Kuznetsov (ZK) model with integer power n…
