酉$C^*$ -代数的性质$(T)$和强性质$(T)$

Property $(T)$ and strong Property $(T)$ for unital $C^*$-algebras

Chi-Wai Leung, Chi-Keung Ng

摘要:

本文对$C^*$ -代数的性质$(T)$的概念(由M. B. Bekka在\cite{Bek-T}中),以及它的一个稍微强一些的版本,称为“强性质$(T)$“(这也是离散群和$\rm II_1$型因子的相应概念的类似物)。更准确地说,我们将给出一些有趣的等价公式以及一些持久性性质的性质$(T)$和强性质$(T)$。我们也将把它们与基础$C^*$ -代数的酉群的某些$(T)$ -型性质联系起来。

英文摘要:

In this paper, we will give a thorough study of the notion of Property $(T)$ for $C^*$-algebras (as introduced by M.B. Bekka in \cite{Bek-T}) as well as a slight stronger version of it, called "strong property $(T)$" (which is also an analogue of the corresponding concept in the case of discrete groups and type $\rm II_1$-factors). More precisely, we will give some interesting equivalent formulations as well as some permanence properties for both property $(T)$ and strong property $(T)$. We will also relate them to certain $(T)$-type properties of the unitary group of the underlying $C^*$-algebra.
