摘要

在之前的工作中,我们定义了sofic群的Banach空间表示的von Neumann维数的扩展版本。主要应用是定义了l^p-维数,并利用它证明了可数离散群G在l^p(G)^{⊕n}上的作用是两两不同构的。我们回答了前一篇论文“An l^p-Version of von Neumann Dimension for Banach Space Representation of Sofic Groups”末尾提出的大部分猜想。处理有限维表示的情况涉及传递到等价关系。这是当前研究的一部分,将在论文“An l^p-Version of von Neumann Dimension for Representations of Equivalence Relations”中解释。
