The conformal embedding convergence conjecture for random planar maps

For each nNn\in{\bf N}, let MnM_n be a random planar map sampled as in the planar-map model above, and embed it into \mathbbmS2\mathbbm S^2 or a subset of \mathbbmC\mathbbm C by a discrete conformal embedding. The embedding induces an area measure and a metric on the target surface. Conformal embedding convergence conjecture. The induced area measure and metric converge in the scaling limit to the area measure and metric, respectively, associated with γ\gamma-LQG. This is a conjectural continuum-limit statement for conformally embedded random planar maps. The supplied context does not indicate a general proof, and convergence of metric properties is described as particularly poorly understood.
