A. III型对称空间上可积方程的约化

Reductions of integrable equations on A.III-type symmetric spaces

V S Gerdjikov, A V Mikhailov, T I Valchev

摘要:

研究了一类与A. III型对称空间相关的可积非线性微分方程。这些空间被实现为形式为SU(N)/S(U(N-k)x U(k))的因子群。我们使用对应于这个对称空间的Cartan对合作为约化群的元素,并将一般的Lax算子限制到这个对称空间。Lax算子的对称性由基本解析解继承,并给出相应Riemann-Hilbert数据的特征。

英文摘要:

We study a class of integrable non-linear differential equations related to the A.III-type symmetric spaces. These spaces are realized as factor groups of the form SU(N)/S(U(N-k) x U(k)). We use the Cartan involution corresponding to this symmetric space as an element of the reduction group and restrict generic Lax operators to this symmetric space. The symmetries of the Lax operator are inherited by the fundamental analytic solutions and give a characterization of the corresponding Riemann-Hilbert data.
