Internal solitary and cnoidal waves of moderate amplitude in a two-layer fluid: the extended KdV equation approximation

We consider travelling internal waves in a two-layer fluid with linear shear currents from the viewpoint of the extended Korteweg-de Vries (eKdV) equation derived from a strongly?nonlinear long-wave model. Using an asymptotic Kodama-Fokas-Liu near-identity transforma?tion, we map the eKdV equation t...
