Last time I introduced the notion of asymptotic expansion in measure and explained its relation with several classical notions. In this talk, I will further introduce more characterisations for asymptotic expansion in terms of projections in (dynamical) Roe algebras. Moreover, I will show that this leads to counterexamples to the coarse Baum-Connes conjecture using warped cones. This is a jointly work with Kang Li and Federico Vigolo.
