The homological connectivity threshold conjecture for k-fold coverage

Let Br(k)B_r^{(k)} be the kk-fold coverage complex on the dd-dimensional torus, let Hi,r(k){\cal{H}}_{i,r}^{(k)} be the event that Hi(Bs(k))Hi(Td)H_i(B_s^{(k)})\cong H_i({\mathbb{T}}^d) for every srs\geq r, and let Λ\Lambda be the model's intensity parameter. Let k1k\geq 1 and 0id20\leq i\leq d-2, and suppose that w(n)w(n)\rightarrow\infty as nn\rightarrow\infty.

Homological connectivity threshold conjecture.

limnP(Hi,r(k))={1Λ=logn+(i+k2)loglogn+w(n),0Λ=logn+(i+k2)loglognw(n).\lim_{n\rightarrow\infty}\mathbb{P}({\cal{H}}_{i,r}^{(k)}) = \begin{cases} 1 & \Lambda = \log n + (i+k-2)\log\log n + w(n), \\ 0 & \Lambda = \log n + (i+k-2)\log\log n - w(n). \end{cases}

The preceding corollary gives only an upper bound for these homological connectivity thresholds, while the conjecture is motivated by the homological connectivity results of Bobrowski (2022).
