摘要

本文应用谱逆问题的方法对一类Toda周期链方程进行积分。对于单波段情况,我们写出了近似杜布罗文方程组的解的显式公式,因此,对于我们的问题。这些解用Jacobi椭圆函数表示。

Integration of equation of Toda periodic chain kind
In this work we apply the method of the inverse spectral problem to integrating an equation of Toda periodic chain kind. For the one-band case we write out explicit formulae for the solutions to an analogue of Dubrovin system of equations and thus, for our problem. These solutions are expressed in term of Jacobi elliptic functions.
