变换群轨道空间的收敛强度
Strength of convergence in the orbit space of a transformation group
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.
