李系统:理论、推广与应用

Lie systems: theory, generalisations, and applications

J. F. Cariñena, J. de Lucas

摘要:

李系统形成一类一阶常微分方程的系统,其通解可以通过特定类型的映射(即所谓的叠加法则)用特定的特解和一组常数的有限族来描述。除了这个基本性质,李系统还具有许多其他几何特征,它们出现在数学和物理的多个分支中,这强烈地激发了他们的研究。这些事实,加上作者最近在李系统理论中的发现,导致了这篇文章的编辑,其目的是在一个独立的指南中描述这些新成就,以整个李系统理论,它们的概括和应用。

英文摘要:

Lie systems form a class of systems of first-order ordinary differential equations whose general solutions can be described in terms of certain finite families of particular solutions and a set of constants, by means of a particular type of mapping: the so-called superposition rule. Apart from this fundamental property, Lie systems enjoy many other geometrical features and they appear in multiple branches of Mathematics and Physics, which strongly motivates their study. These facts, together with the authors' recent findings in the theory of Lie systems, led to the redaction of this essay, which aims to describe such new achievements within a self-contained guide to the whole theory of Lie systems, their generalisations, and applications.
