AI 中文摘要
我们计算了李群上左不变磁系统的磁曲率(在阿森扎意义下),探讨了曲率性质与代数性质之间的关系,将米尔诺1976年关于左不变度量几何的经典论文中的一些结果推广到磁学情形。我们还讨论了非平凡双不变磁系统的存在性,并在一些具体例子中展示了由此产生的曲率公式,包括海森堡群。
英文摘要
We compute the magnetic curvatures (in the sense of Assenza) of left-invariant magnetic systems on Lie groups and explore relations between curvature properties and algebraic properties, extending to the magnetic setting a number of results from Milnor's classic 1976 paper on the geometry of left-invariant metrics. We also discuss the existence of non-trivial bi-invariant magnetic systems and exhibit the resulting curvature formulas in some concrete examples, including the Heisenberg group.
