Abstract :
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 m-symmetry method. Moreover we obtain Lagrangian and m-conservation law
of the gmKdVcc equation and the gmKdVvc equation using the variational problem method.
