变换群轨道空间的收敛强度

Strength of convergence in the orbit space of a transformation group

Robert Archbold, Astrid an Huef

摘要:

设(G,X)是一个第二可数变换群,G自由作用在X上.它表明,测量理论积累的行动和拓扑强度的轨道空间X/G中的收敛提供了量化的程度的非适当的行动的等价方式。这些概念通过变换群C* 代数的表示论联系起来。

英文摘要:

Let (G, X) be a second-countable transformation group with G acting freely on X. It is shown that measure-theoretic accumulation of the action and topological strength of convergence in the orbit space X/G provide equivalent ways of quantifying the extent of non-properness of the action. These notions are linked via the representation theory of the transformation-group C*-algebra.
