WebSep 1, 2024 · One is referred to [12] for more details of coarse spaces and their Roe algebras. There had been a lot of studies about the ideals of the Roe algebras, one is referred to [2], [3], [4] for more information. However, there are few papers which focus their interests in the study of the quotients of Roe algebras.

Webthe ideals of the uniform Roe algebra C∗ u (X,E) in which controlled propagation operators are dense are exactly those ideals determined by the coarse geometry of (X,E). The purpose of the present paper is to generalize the main idea in [2] for the uniform Roe algebras to the case of the Roe algebras. In Section 2, we recall the WebNote that when the underlying space comes from a discrete group equipped with a word length metric, then the associated uniform Roe algebra has the form of a crossed product by the group itself acting on an abelian C ...

It follows from the following localization result for … WebRoe algebras are coarse invariants, meaning that if X and Y are coarsely equivalent metric spaces, then their Roe algebras are isomor- phic.
