有限因子子代数的强奇异性

Strong singularity for subalgebras of finite factors

Guyan Robertson, Allan M. Sinclair, Roger R. Smith

摘要:

在本文中,我们发展的理论,强奇异子代数的冯诺依曼代数,开始在早期的工作。我们主要考察了由可数离散群产生的$\tto$型因子的情形。给出了强奇异性的简单判据,并利用它们构造了强奇异子代数。我们特别关注的群体的几何对象,其中潜在的几何形状导致强奇异性。

英文摘要:

In this paper we develop the theory of strongly singular subalgebras of von Neumann algebras, begun in earlier work. We mainly examine the situation of type $\tto$ factors arising from countable discrete groups. We give simple criteria for strong singularity, and use them to construct strongly singular subalgebras. We particularly focus on groups which act on geometric objects, where the underlying geometry leads to strong singularity.
