研究微分系统延拓结构的几何方法及其在可积系统中的应用

A Geometric Method to Investigate Prolongation Structures for Differential Systems With Applications to Integrable Systems

Paul Bracken

摘要:

讨论了几类一般系统的一类延拓结构。它们基于一组1-形式,其中可积性条件的基础结构群对应于SL(2,R),O(3)或SU(3)的李代数。每一个都将依次考虑,后两个系统代表了更大的3by 3情况。这种几何方法适用于所有这三个系统obatin延长结构明确。在这两种3by 3的情况下,延长结构减少到三个较小的2by 2问题的情况。许多类型的守恒律可以在不同的发展阶段获得,并在最后,一个单一的结果,显示如何可以做到这一点。

英文摘要:

A type of prolongation structure for several general systems is discussed. They are based on a set of one-forms in which the underlying structure group of the integrability condition corresponds to the Lie-algebra of SL (2,R), O(3), or SU(3). Each will be considered in turn and the latter two systems represent larger 3by3 cases. This geometric approach is applied to all three of these systems to obatin prolongation structures explicitly. In both 3by3 cases the prolongation structure is reduced to the situation of three smaller 2by2 problems. Many types of conservation laws can be obtained at different stages of the development, and at the end, a single result is developed to show how this can be done.
