Singleton end-image conjecture for Tutte embeddings

About 1 year old · traced to

Let Mk\mathcal M_k be the supercritical random planar map and let HkH_k be its Tutte embedding into D‾\overline{\mathbb D}. For an end ω\omega of Mk\mathcal M_k, define its image Hk(ω)⊂D‾H_k(\omega)\subset\overline{\mathbb D} as in the source. Singleton end-image conjecture. Almost surely, Hk(ω)H_k(\omega) is a singleton for every end ω\omega of Mk\mathcal M_k. This is motivated by the fact that singular points of the limiting LQG metric are totally disconnected and are expected to correspond to ends of the map; the conjecture asserts that each discrete end has a unique Euclidean image under the embedding.
