Abstract

Abstract Based on the symplectic Lie algebra $$\mathfrak {sp}(4)$$ sp ( 4 ) , we obtain two integrable hierarchies of $$\mathfrak {sp}(4)$$ sp ( 4 ) , and by using the trace identity, we give their Hamiltonian structures. Then, we use $$2\times 2$$ 2 × 2 Kronecker product, and construct integrable coupling systems of one soliton equation. Next, we consider two bases of Lie algebra $$\mathfrak {so}(5)$$ so ( 5 ) , and we get the corresponding two integrable hierarchies. Finally, we discuss the relation between the integrable hierarchies of two different bases associated with Lie algebra $$\mathfrak {so}(5)$$ so ( 5 ) .

与李代数相关的一些孤子层次$$\mathfrak {sp}(4)$$及 $$\mathfrak {so}(5)$$

摘要基于辛李代数$$\mathfrak {sp}(4)$$ sp(4)，得到了$$\mathfrak {sp}(4)$$ sp(4)的两个可积层次，并利用迹恒等式给出了它们的哈密顿结构。然后利用$$2\times 2$$ 2 × 2 Kronecker积，构造了单孤子方程的可积耦合系统。接下来，我们考虑了李代数$$\mathfrak {so}(5)$$ so(5)的两个基，得到了对应的两个可积层次。最后，我们讨论了与李代数相关的两种不同基的可积层次之间的关系$$\mathfrak {so}(5)$$ so(5)。
