利用代数变换,构造了与文献[4]中的Loop代数A2的子代数等价的Loop代数A1的一个子代数A1。再将A1扩展为一个高维的Loop代数G,利用G设计了一个等谱问题,结合子代数间直和运算和同构关系,得到了广义Schroedinger方程族的一类扩展可积系统。作为约化情形,求得了著名的广义Schroedinger方程的可积耦合系统。
利用代數變換,構造瞭與文獻[4]中的Loop代數A2的子代數等價的Loop代數A1的一箇子代數A1。再將A1擴展為一箇高維的Loop代數G,利用G設計瞭一箇等譜問題,結閤子代數間直和運算和同構關繫,得到瞭廣義Schroedinger方程族的一類擴展可積繫統。作為約化情形,求得瞭著名的廣義Schroedinger方程的可積耦閤繫統。

A subalgerbra A 1,which is equivalent to the subalgebra of the Loop algebra A2 in [4], is constructed by making use of algebraic transformation, and then a high - dimensional Loop alegebra G is presented in terms of A1. An isospectral problem is established following G by using direct sum operators and isomorphic relations among subalgebras. It is concluded that a class of expanding integrable system for generalized Schrodinger hierarchy of evolution equations is obtained. As in reduction cases, the integrable coupling of the famous generalized Schroedinger e -quation is presented.
