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 American Mathematical Society hosts AMS Open Math Notes , which is “a repository of freely downloadable mathematical works in progress hosted by the AMS as a service to researchers, teachers and students.” The Open Math Notes homepage continues “These draft works include course notes, textbooks, and research expositions in progress.
WebAbstract. We study MB-representations of algebras and ideals when they are relativized to a subset, and when one considers the operations of sum and intersection for families of algebras and ideals. We observe that the algebras 0 1, 3 WebTheorem 1.1. Nuclear uniform Roe algebras associated to bounded geometry metric spaces only have inner derivations. Key ingredients in the proof come from recent groundbreaking work on uni-form Roe algebras of Braga-Farah [2], Spakula-Tikuisis [13], and Spakula-Zhang [14]. We leave the following natural questions open.
