The coarse geometric p\ell^p-Novikov conjecture

Let Γ\Gamma be a discrete metric space with bounded geometry. For p(1,)p\in(1,\infty), let Bp(Γ)B^p(\Gamma) be its p\ell^p-Roe algebra and BLp(Γ)B_L^p(\Gamma) its p\ell^p-localization algebra. For the Rips complex Pd(Γ)P_d(\Gamma) at scale dd, the evaluation homomorphism e:BLp(Pd(Γ))Bp(Pd(Γ))e:B_L^p(P_d(\Gamma))\to B^p(P_d(\Gamma)) induces the index map

e:limdK(BLp(Pd(Γ)))limdK(Bp(Pd(Γ)))K(Bp(Γ)).e_*: \lim_{d\to\infty} K_*(B_L^p(P_d(\Gamma))) \to \lim_{d\to\infty} K_*(B^p(P_d(\Gamma)))\cong K_*(B^p(\Gamma)).

The coarse geometric p\ell^p-Novikov conjecture. If Γ\Gamma is a discrete metric space with bounded geometry, then the index map ee_* is injective.

This is the coarse geometric p\ell^p-Novikov conjecture, an p\ell^p analogue of the coarse Novikov conjecture. The paper proves it for metric spaces with bounded geometry that admit a coarse embedding into a simply connected complete Riemannian manifold of nonpositive sectional curvature; the general assertion remains open.
