Sub-ODE method and soliton solutions for the variable-coefficient mKdV equation. (English) Zbl 1171.35467
Summary: An auxiliary equation is used for an analytic study of the time-variable coefficient modified Korteweg-de Vries (mKdV) equation. Five sets of new exact soliton-like solutions are obtained. The results show that the pulse parameters are time-dependent variable coefficients. Moreover, the basic conditions for the formation of derived solutions are presented.
