Triviality of critical Fortuin-Kasteleyn decorated planar maps for $q>4$

We consider infinite random planar maps decorated by the critical Fortuin-Kasteleyn model with parameter $q>4$. The paper demonstrates that when appropriately rescaled, these maps converge in law to the infinite continuum random tree as pointed metric-measure spaces, that is, with respect to the local Gromov-Hausdorff-Prokhorov topology. Furthermore, we also show that these maps do not admit any Fortuin-Kasteleyn loops with a macroscopic graph distance diameter. Our proof is based on Scott Sheffield’s hamburger-cheeseburger bijection.
