  • The Extended Korteweg-de Vries Equation 
    Hefter, E.F. (Berlin, Boston : De Gruyter, 1982)
    A slight and natural extension of the traditional Korteweg-de Vries equation (KdV) allows all (or groups) of its solitons to have the same velocity thus facilitating the application of the KdV to realistic quantum mechanical ...
