广义Lax矩阵和广义初始条件下Lax方程的积分算法

The Integration Algorithm of Lax equation for both Generic Lax matrices and Generic Initial Conditions

Wissam Chemissany, Pietro Fre, Alexander S. Sorin

摘要:

Lax方程的一些物理应用要求它的通解是一般的Lax矩阵和一般的不一定可对角化的初始条件。在本文中,我们完成了在[arXiv:0903.3771]中开始的关于具有一般Lax算子和一般初始条件的Lax方程的积分的分析。我们提出了一个完整的一般积分公式,适用于任何(可对角化或不可对角化)的初始Lax矩阵,并给出了一个原始的严格的数学证明,其有效性依赖于没有以前发表的结果。

英文摘要:

Several physical applications of Lax equation require its general solution for generic Lax matrices and generic not necessarily diagonalizable initial conditions. In the present paper we complete the analysis started in [arXiv:0903.3771] on the integration of Lax equations with both generic Lax operators and generic initial conditions. We present a complete general integration formula holding true for any (diagonalizable or non diagonalizable) initial Lax matrix and give an original rigorous mathematical proof of its validity relying on no previously published results.
