Sy. Lou et Ll. Chen, SOLITARY WAVE SOLUTIONS AND CNOIDAL WAVE SOLUTIONS TO THE COMBINED KDV AND MKDV EQUATION, Mathematical methods in the applied sciences, 17(5), 1994, pp. 339-347
This paper presents a mapping approach for the construction of exact s
olutions to the combined KdV and mKdV equation. There exist two types
or soliton solutions which will reduce back to those of the KdV and mK
dV equations in some appropriate limits. Four types of the general eno
idal wave solutions are also obtained.
