提出了一类与l(4)相关的具有自洽源的孤子方程族的可积耦合(Yu F J和Li L 2009 Appl. Math. Comput. 207 171;于法建2008物理快报。A 372 6613)。在此基础上,利用圈代数l(4)构造了具有自洽源的孤子族的两个可积耦合.本文还指出了这些文献中存在的一些错误,并对这些错误进行了修正,建立了新的公式。 所用方法可以推广到其它带有自相容源的新可积系统.
A kind of integrable coupling of soliton equations hierarchy with self-consistent sources associated with l(4) has been presented (Yu F J and Li L 2009 Appl. Math. Comput. 207 171; Yu F J 2008 Phys. Lett. A 372 6613). Based on this method, we construct two integrable couplings of the soliton hierarchy with self-consistent sources by using the loop algebra l(4). In this paper, we also point out that there are some errors in these references and we have corrected these errors and set up new formula. The method can be generalized to other soliton hierarchy with self-consistent sources.
