Notes on ideals of roe algebras
WebNote that if g = g 1 g 2 is a direct sum decomposition of a Lie algebra g into two Lie subalgebras g 1;g 2, then [g 1;g 2] = 0, in the sense that [X;Y] = 0 for all X2g 1 and Y 2g 2; it follows that g 1;g 2 are in fact ideals of g. Finally, Lie algebras should \talk to each other" in a way that is compatible with the Lie bracket operation: De ...

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 ...

WebLet \(C_u^* (X)\) be the uniform Roe algebra of a coarse space X with uniformly locally finite coarse structure. We show that an operator G in \(C_u^* (X)\) is a ghost element if and only if the finite propagation operators in the principal ideal 〈G〉 are all compact operators.
