摘要:

研究了一类含有三阶和四阶色散项的非线性薛定谔方程的2+1可积推广的非等谱线性问题.仔细研究了拉克斯对的经典对称性和相关的约化。我们得到了几个减少的拉克斯对,在某些情况下,在1+1维的非等谱问题。

英文摘要:

A non-isospectral linear problem for an integrable 2+1 generalization of the non linear Schrödinger equation, which includes dispersive terms of third and fourth order, is presented. The classical symmetries of the Lax pair and the related reductions are carefully studied. We obtain several reductions of the Lax pair that yield in some cases non-isospectral problems in 1+1 dimensions.
