Bounded geometry Borel conjecture for foliations

Let (M,F)(M,\mathcal{F}) be a foliation on a compact manifold, let BGBG be the classifying space of its holonomy groupoid, and let SxS_x be the leaf through xBGx\in BG. Let Luf\mathcal{L}^{uf} be the cosheaf of uniformly finite LL-homology of the leaves, and let LF,bg(M)L_*^{\mathcal{F},bg}(M) denote the bounded-geometry foliated surgery group. Bounded geometry Borel conjecture for foliations. If the leaves of (M,F)(M,\mathcal{F}) are aspherical, then

H(BG;Luf(Sx))LF,bg(M)H_*(BG;\mathcal{L}^{uf}(S_x))\to L_*^{\mathcal{F},bg}(M)

is an isomorphism. This is the bounded-geometry Borel-type rigidity statement corresponding to the bounded-geometry foliated surgery theory.
