Notes on ideals of roe algebras
Webthe main tool in order to generalize the results for uniform Roe algebras obtained in [BF18, BFV19] to the context of Roe algebras (Lemma 3.1). Section 4 starts by dealing with embeddings between Roe algebras, which is the essential step so that we can have the asymmetry of Theorem 1.3, i.e., the fact that only Y has to satisfy a geometric ... WebNov 1, 2004 · Let C u ∗ (X, E) be the uniform Roe algebra of a coarse space (X, E) with uniformly locally finite coarse structure. By a controlled truncation technique, we show …

WebRoe algebras are coarse invariants, meaning that if X and Y are coarsely equivalent metric spaces, then their Roe algebras are isomor- phic. Motivated in part by the coarse Baum-Connes conjecture, we show that the converse statement is true … WebIn this paper, we aim to extend the studies [M. R. Alimoradi, R. Rezaei and M.

Nuclear uniform Roe algebras associated to bounded geometry metric spaces only have inner derivations.
