Wronskian solutions to the KdV equation via Bäcklund transformation

Qi-fei Xuan, Mei-ying Ou, Da-jun Zhang

摘要:

本文讨论了KdV方程在孤子与孤子之间、双子与双子之间、位置与位置之间、有理解与有理解之间、复子与复子之间的贝克隆变换。研究了KdV方程双线性贝克隆变换的Wronskian项满足的条件.通过选择合适的Wronskian元和双线性贝克隆变换中的参数,得到了多种解之间的变换.

英文摘要:

In the paper we discuss the Bäcklund transformation of the KdV equation between solitons and solitons, between negatons and negatons, between positons and positons, between rational solution and rational solution, and between complexitons and complexitons. We investigate the conditions that Wronskian entries satisfy for the bilinear Bäcklund transformation of the KdV equation. By choosing suitable Wronskian entries and the parameter in the bilinear Bäcklund transformation, we obtain transformations between many kinds of solutions.
