Notes on ideals of roe algebras
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 … WebWe show that in a lattice effect algebra, each lattice ideal is an effect algebra ideal if and only if the lattice effect algebra is an orthomodular lattice.

WebJan 1, 2024 · Further we give the correct ideal generation formula on residuated lattices. Moreover, we extend the concepts of annihilators and α-ideals to MTL-algebras and focus on studying the relations between them. Furthermore, we show that the set I α (M) of all α-ideals on a linear MTL-algebra M only contains two trivial α-ideals {0} and M. WebNote that Kn−q (C) = Z if n−q is even, and Kn−q (C) = {0} if n − q is odd in which case the last statement is empty. The main novelty of this note is the localization result for the partitioned man- ifold index. It follows from the following localization result for …
Webuniform Roe algebras C∗ u(X)by using the internal structure of the ideals generated by this type of operators. Based on a recent work of the authors [4], 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 (Theorem 3.1). Thus, the ... 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 …
