本文首先给出了伴随本征函数所产生的倒易变换,并给出了Lax算子、本征函数和伴随本征函数在这种新的倒易变换下的相应变化。然后讨论由本征函数和伴随本征函数产生的互逆变换的连续作用。此外,我们还研究了不同类型的倒易变换的交换性。上述结果对于构造新的解是非常有用的。
In this paper, we work out the reciprocal transformations generated by the adjoint eigenfunctions, and write down the corresponding changes of the Lax operators, eigenfunctions and adjoint eigenfunctions under this kind of new reciprocal transformations at first. Then we discuss the successive actions of the reciprocal transformations generated by the eigenfunctions and the adjoint eigenfunctions. Also we investigate the commutativity of different types of the reciprocal transformations. The above results are very useful to construct the new type solutions.
