Abstract

In this paper, we conduct further studies on geometric and analytic properties of asymptotic expansion in measure. More precisely, we develop a machinery of Markov expansion and obtain an associated structure theorem for asymptotically expanding actions. Based on this, we establish an analytic characterisation for asymptotic expansion in terms of the Druţu–Nowak projection and the Roe algebra of the associated warped cones. As an application, we provide new counterexamples to the coarse Baum–Connes conjecture.
