ABSTRACT:
The determinant representation of three-fold Darboux
transformation for a variable-coefficient modified KdV equation is displayed
based on the technique used to solve Ablowitz-Kaup-Newell-Segur system.
Additionally, the nonsingular positon solutions of the variable-coefficient
modified KdV equation are firstly discovered analytically and graphically.
