The application of the auxiliary equation technique to a generalized mKdV equation with variable coefficients

摘要

The auxiliary differential equation technique is employed to investigate a generalized mKdV equation with variable coefficients. The Jacobi elliptic function wave-like solutions of the equation are expressed under several circumstances. The degenerated soliton-like and trigonometric function solutions are discussed in detail as the modulus of the Jacobi elliptic wave-like solutions tends to 1 and 0, respectively.
