The coarse Novikov conjecture for discrete metric spaces

Let XX be a discrete metric space with bounded geometry. For each d>0d>0, let Pd(X)P_d(X) be its Rips complex, and let CL(Pd(X))C^*_L(P_d(X)) and C(X)C^*(X) denote its localization and Roe algebras. The evaluation map is

ev ⁣:limdCL(Pd(X))C(X).ev\colon \lim_{d\to\infty} C^*_L(P_d(X))\to C^*(X).

Coarse Novikov conjecture. The induced map

ev ⁣:limdK(CL(Pd(X)))K(C(X))ev_*\colon \lim_{d\to\infty}K_*( C^*_L(P_d(X)))\to K_*( C^*(X))

is injective. This conjecture asserts injectivity of the coarse assembly map and is the coarse analogue of the Strong Novikov Conjecture. Its resolution is not supplied in the source.
