Supercritical fully packed O(2)O(2) maps scaling-limit conjecture

About 3 years old · traced to

Fix s>1s>1, and let (Mk′,Lk′)(M_k',L_k') be sampled from the modified iteration procedure. Let cL∈(1,25)\mathbf c_{\mathrm L}\in(1,25) be the central charge parameter determined by ss through

s=exp⁡\originalleft(4−Q2Qπ\aftergroup\originalright),Q=cL−16.s=\exp\mathopen{}\mathclose\bgroup\originalleft(\frac{\sqrt{4-Q^2}}{Q}\pi\aftergroup\egroup\originalright),\qquad Q=\sqrt{\frac{\mathbf c_{\mathrm L}-1}{6}}.

A CLE4_4-decorated supercritical LQG disk is the continuum surface with the corresponding central charge parameter, decorated by CLE4_4. Supercritical map scaling-limit conjecture. Under an appropriate scaling limit as k→∞k\to\infty, (Mk′,Lk′)(M_k',L_k') converges to a CLE4_4-decorated supercritical LQG disk, with central charge parameter cL∈(1,25)\mathbf c_{\mathrm L}\in(1,25) depending on ss as above. The conjecture is motivated by the modified iteration, the previously stated fully packed O(2)O(2) conjecture, and the Markov property of the CLE4_4-decorated supercritical LQG disk; it remains open.
