Abstract:
With the aid of the reciprocal transformation and the associated Vakhnenko equation, we construct and study a Bäcklund transformation (BT) involving both independent and dependent variables for the Vakhnenko equation. We derive the corresponding nonlinear superposition formula or $2$-BT and $3$-BT and rewrite them in terms of Pfaffians. We also discuss the representation for the general $N$-BT. As applications, some explicit solutions of the Vakhnenko equation are presented.
Keywords:
Vakhnenko equation, Bäcklund transformation, nonlinear superposition formula, loop soliton solution.
