The loop-erased random-walk up-to-constants passage estimate

About 13 years old · traced to

Let z∈Dz\in\mathbb{D}, let ϵ>0\epsilon>0 be sufficiently small, and let ZZ, WwW^w, ξx\xi_x, and σD\sigma_{\mathbb{D}} have the meanings used in the loop-erased-random-walk estimates: ZZ is the relevant random walk, ξx\xi_x is its hitting time of xx, WwW^w is the walk started at ww, and σD\sigma_{\mathbb{D}} is the exit time from the disk. Let L⁡(Z[0,ξx])\operatorname{L}(Z[0,\xi_x]) be the loop-erasure of Z[0,ξx]Z[0,\xi_x], and let Es⁡(ϵn)\operatorname{Es}(\epsilon n) be the corresponding nonintersection probability. Up-to-constants passage conjecture. For the points ww and xx in the configuration under consideration,

P(L⁡(Z[0,ξx])∩Ww[1,σD]=∅)≍Es⁡(ϵn).\mathbb{P}\left(\operatorname{L}(Z[0,\xi_x])\cap W^w[1,\sigma_{\mathbb{D}}]=\emptyset\right)\asymp\operatorname{Es}(\epsilon n).

This estimate is proposed as the missing lower-bound ingredient for the conditional occupation-measure estimate. The source had established only upper bounds and suggested that the lower bound might follow from modifying the proof strategy.
