Sofic群II的巴拿赫空间表示的von Neumann维数的l^{p}-形式

An l^{p}-Version of von Neumann Dimension for Banach Space Representation of Sofic Groups II

Ben Hayes

摘要:

在以前的工作中,我们定义了sofic群的巴拿赫空间表示的vonNeumann维数的扩展形式。主要的应用是l^{p}-维的定义,并利用它证明了可数离散群G在l^{p}(G)^{o + n}上的作用是两两不同构的。我们回答了前一篇文章“巴拿赫空间表示的von Neumann维数的l^{p}-版本”结尾部分的大部分猜想。“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等价关系”中解释。"

英文摘要:

In previous work, we defined extended versions of von Neumann dimension for Banach space representations of sofic groups. The main application was a definition of l^{p}-dimension and, using this, a proof that the actions of a countable discrete group G on l^{p}(G)^{oplus n} are pairwise non-isomorphic. We answer most of the Conjectures stated at the end of the previous paper "An l^{p}-Version of von Neumann Dimension for Banach Space Representation of Sofic Groups." Tackling the case of finte-dimensional representations involved passing to equivalence relations. This is part of current research to be explained in the paper "An l^{p}-Version of von Neumann Dimension for Representations of Equivalence Relations."
