Roe型代数的刚性框架

A rigidity framework for Roe-like algebras

Diego Martínez, Federico Vigolo

AI总结:

本文建立了一个研究Roe型C*-代数刚性问题的统一框架,证明Roe代数间的稳定同构必产生粗等价,并将粗几何与算子代数的对应关系纳入范畴框架,同时刻画了外自同构群。

摘要:

在本回忆录中,我们建立了一个框架来研究可数生成粗空间的Roe型C*-代数的刚性问题。主要目标是给出真(扩张)度量空间的C*-刚性问题的一个完整且自包含的解答。即,我们证明Roe代数之间的(稳定)同构总是产生粗等价。材料的组织方式旨在为Roe代数、受控传播算子代数以及拟局部算子代数的C*-刚性提供统一证明。我们还证明了一个更精细的C*-刚性陈述,该陈述具有若干额外应用。例如,我们可以将粗几何与算子代数之间的对应关系置于范畴框架中,并且我们证明这些C*-代数的外自同构群都同构于粗空间的粗等价群。

英文摘要:

In this memoir we develop a framework to study rigidity problems for Roe-like C*-algebras of countably generated coarse spaces. The main goal is to give a complete and self-contained solution to the problem of C*-rigidity for proper (extended) metric spaces. Namely, we show that (stable) isomorphisms among Roe algebras always give rise to coarse equivalences. The material is organized as to provide a unified proof of C*-rigidity for Roe algebras, algebras of operators of controlled propagation, and algebras of quasi-local operators. We also prove a more refined C*-rigidity statement which has several additional applications. For instance, we can put the correspondence between coarse geometry and operator algebras in a categorical framework, and we prove that the outer automorphism groups of these C*-algebras are all isomorphic to the group of coarse equivalences of the coarse space.
