The uniform spanning tree scaling conjecture to infinite canonical super-Brownian motion

About 22 years old · traced to

Let d>4d>4. For each r≥2r\geq2, let ρn⃗(st)(x⃗)\rho^{(\mathrm{st})}_{\vec n}(\vec x) denote the uniform spanning tree rr-point function, with time coordinates given by distances in the tree from the origin. The constants A,V,vA,V,v and δ∈(0,1)\delta\in(0,1) are those in (rhoscal).

Uniform spanning tree scaling conjecture. There exist constants A,V,vA,V,v and δ∈(0,1)\delta\in(0,1) such that (rhoscal) holds for ρ(st)\rho^{(\mathrm{st})}.

This conjectures that the uniform spanning tree has ICSBM as its scaling limit above dimension 44. The motivation is Wilson's construction and the diffusive scaling of loop-erased random walk in dimensions greater than 44, but the required multi-point convergence is left open.
