Weak convergence conjecture for the pro-ell random-group measures

Let Γ=Z/2Z\Gamma=\mathbb{Z}/2\mathbb{Z} and let ellell be an odd prime. Let PΓ,q,{\mathcal P}_{\Gamma,q,\ell} be the coarser topological space obtained by restricting the basic opens of PΓ,q{\mathcal P}_{\Gamma,q} to finite ellell-group quotients, and let nuq,,nnu_{q,\ell,n} be the probability measures defined from the random groups Yq,nY_{q,n}.

Weak convergence conjecture. On PΓ,q,{\mathcal P}_{\Gamma,q,\ell}, the measures nuq,,nnu_{q,\ell,n} converge weakly, as nn\to\infty, to the measure muΓ,qmu_{\Gamma,q} from the existence and uniqueness conjecture.

The conjecture asserts that the pro-\ell random-group model realizes the predicted limiting distribution in the case Γ=Z/2Z\Gamma=\mathbb{Z}/2\mathbb{Z}. It is a refinement of the moment calculation for Yq,nY_{q,n} and remains open.
