Abstract:

 In this paper, by using the unknown function transformation and with the aid of Mathematica, auto-Backlund transformation of the modified dispersive water waves equations is obtained, and Darboux transformations between it、heat equation and linear equation are derived. Based on these results, multisoliton solutions、rational fraction solutions and other exact solutions for the equations are found. This way can be also applied to other nonlinear equations.

Key words: Modified dispersive water waves equation, Unknown function transformation, Auto-Backlund transformation, Darboux transformation, Exact solution, Multi-soliton solution
