Symmetries, solutions and conservation laws of a class of nonlinear dispersive wave equations

Gandarias, Maria Luz; Khalique, Chaudry Masood (Elsevier, 2016)

In this paper we consider a damped externally excited Korteweg-de Vries (KdV) equation with a forcing term. We derive the classical Lie symmetries admitted by the equation. We then find that the damped externally excited ...
