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 … 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 …

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.

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.
