摘要

我们研究了任意维度的CR接触manifolds上的解析扭转和类似于eta的不变量，这些接触manifolds允许一个圆的横向作用，并配备一个单元表示。我们的研究表明，当使用这种几何中出现的相关算子的谱来定义时，所涉及的谱序列可以从拓扑学的角度和作为里布流的纯动力学函数的角度来整体解释。

Topological and dynamical aspects of some spectral invariants of contact manifolds with circle action

We study analytic torsion and eta like invariants on CR contact manifolds of any dimension admitting a circle transverse action, and equipped with a unitary representation. We show that, when defined using the spectrum of relevant operators arising in this geometry, the spectral series involved can been interpreted in their whole, both from a topological viewpoint, and as purely dynamical functions of the Reeb flow.
