摘要:

我们重新考虑二维非退化二阶超可积系统,将其视为共形曲面上的几何结构。这扩展了作者先前为三维及更高维(伪)黎曼流形所发展的形式体系。二维非退化二阶超可积性的控制方程在结构上与高维情形显著不同。具体而言,我们找到了共形协变的结构方程,从而能够从几何上对共形曲面上的非退化二阶超可积系统(的共形类)进行分类。随后,我们专门研究具有(伪)黎曼度量的曲面上的二阶真超可积系统,并获得了与欧氏空间已知方程一致的结构方程。最后,我们给出了一组显式的纯代数方程,用以定义在所有常曲率曲面上参数化此类系统的簇。

英文摘要:

We reconsider non-degenerate second order superintegrable systems in dimension two as geometric structures on conformal surfaces. This extends a formalism developed by the authors, initially introduced for (pseudo-)Riemannian manifolds of dimension three and higher. The governing equations of non-degenerate second order superintegrability in dimension two are structurally significantly different from those valid in higher dimensions. Specifically, we find conformally covariant structural equations, allowing one to classify the (conformal classes of) non-degenerate second order superintegrable systems on conformal surfaces geometrically. We then specialise to second order properly superintegrable systems on surfaces with a (pseudo-)Riemannian metric and obtain structural equations in accordance with the known equations for Euclidean space. We finally give a single explicit set of purely algebraic equations defining the variety parametrising such systems on all constant curvature surfaces.
