UIMS origin-loop tail exponent conjecture

Let (M,Γ)(\mathcal M,\Gamma) be the planar map and loop collection associated with the UIMS, and let 0\ell_0 be the loop or infinite path in Γ\Gamma passing through 0Z0\in\mathbb Z. Write dd for the exponent appearing in the paper's graph-distance bound and set α=12(32)\alpha=\frac12(3-\sqrt2). UIMS origin-loop tail conjecture. As kk\to\infty,

P\originalleft[diamM(0)k\aftergroup\originalright]kd(1α)o(1),\mathbb P\mathopen{}\mathclose\bgroup\originalleft[\operatorname{diam}_{\mathcal M}(\ell_0)\ge k\aftergroup\egroup\originalright]\ge k^{-d(1-\alpha)-o(1)},

and

P\originalleft[#{vertices in 0}k\aftergroup\originalright]k(1/α1)o(1).\mathbb P\mathopen{}\mathclose\bgroup\originalleft[\#\{\text{vertices in }\ell_0\}\ge k\aftergroup\egroup\originalright]\ge k^{-(1/\alpha-1)-o(1)}.

The paper states that the proven exponent is not expected to be optimal; these sharper lower-tail predictions remain open.
