Symmetry properties of a generalized Korteweg-de Vries equation and some explicit solutions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
The symmetry group method is applied to a generalized Korteweg-de Vries equation and several classes of group invariant solutions for it are obtained by means of this technique. Polynomial, trigonometric, and elliptic function solutions can be calculated.
