Strict comparison holds in the uniform Roe algebra of a discrete amenable group
George A. Elliott, Chun Guang Li, Zhuang Niu +1
Let be a countable discrete amenable group, and let . It is shown that if are positive elements such that $$\mathrm{d}_…
Dynamic asymptotic dimension growth for group actions and groupoids
Hang Wang, Yanru Wang, Jianguo Zhang +1
We introduce the notion of dynamic asymptotic dimension growth for actions of discrete groups on compact spaces, and more generally for locally compact étale groupoids. Moreover, w…
coarse Baum-Connes conjecture via coarse geometry
Hang Wang, Yanru Wang, Jianguo Zhang +1
In this paper, we investigate the coarse Baum-Connes conjecture for via coarse structure, which is a refinement of the bounded coarse structure on…
Uniformly bounded fibred coarse embeddability and uniformly bounded a-T-menability
Jianguo Zhang, Dapeng Zhou
In this paper, we introduce the concept of uniformly bounded fibred coarse embeddability of metric spaces, generalizing the notion of fibred coarse embeddability defined by X. Chen…
