چکیده
|
The goal of this paper is to calculate the order reduction of the generalized mkdv equation with constant coefficients (gmkdvcc) and the generalized mkdv equation with variable-coefficients (gmkdvvc) using the mu-symmetry method. moreover we obtain lagrangian and mu-conservation law of the gmkdvcc equation and the gmkdvvc equation using the variational problem method.
