本文提出了一种构造Sech平方孤子系统的Backlund变换的方法,作为通常基于双线性交换形式的方法的替代。它示出的工作,而不需要一个双线性表示的情况下,一个非本地Boussinesq方程。得到的双线性BT产生一个修改的非局部Boussinesq方程。
A method for constructing Backlund transformations (BT's) for sech-squared soliton systems is presented as an alternative to the usual procedure based on the bilinear exchange formalism. It is shown to work without the need of a bilinear representation in the case of a nonlocal Boussinesq equation. The obtained bilinear BT produces a modified nonlocal Boussinesq equation.
