Finiteness conjecture for top integral cohomology of configuration spaces

Let MM be an orientable even dimensional manifold. Assume

rank(Hd1(M;Z))=0.\operatorname{rank}(H^{d-1}(M;\mathbb{Z}))=0.

Finiteness conjecture. There exist k0Nk_{0}\in\mathbb{N} such that

Htop(Ck(M);Z)H^{\operatorname{top}}(C_{k}(M);\mathbb{Z})

is finite for every kk0k\geq k_{0}.

This conjecture concerns the eventual finiteness of the top nonzero integral cohomology groups of configuration spaces when the (d1)(d-1)st cohomology of the manifold has rank zero. The preceding examples indicate finiteness for configuration spaces of R2\mathbb{R}^{2}, while the general pattern in this setting remains unclear.
