离散动力系统的匹配对

Matched pairs of discrete dynamical systems

Oğul Esen, Serkan Sütlü

摘要:

研究李群胚和李代数胚的匹配对。离散欧拉-拉格朗日方程的匹配李群胚对书面。这样,一个几何框架来分析一个离散系统分解成两个相互作用的子系统建立。给出了平凡广群上的离散动力学和特殊线性群上的离散动力学两个例子来说明这种策略。

英文摘要:

Matched pairs of Lie groupoids and Lie algebroids are studied. Discrete Euler-Lagrange equations are written for the matched pairs of Lie groupoids. As such, a geometric framework to analyse a discrete system by decomposing it into two mutually interacting subsystems is established. Two examples are provided to illustrate this strategy; the discrete dynamics on the trivial groupoid, and the discrete dynamics on the special linear group.
