Lemma 11 ([Scores at separated anchors]). Let U be a cell union and let D be any collection of anchors mutually separated by more than r , all within distance Ds of U . There is a coarse-cell cover S of the (D+RA)s neighborhood of U , with |S|≤C(D+RA+2)3|U| , such that, pathwise, ∑a∈ D A-(a;ω) ≤C∫0δ/2 (w(t)+r-3 )nS(ω(t))\,dt. The analogous inequality holds for the end scores after time reversal. The assertion holds also when the anchors are chosen from the paths by an arbitrary measurable rule, provided their separation and location hold for each realization. There is B0=C(1+K2/ζ3) such that the exponential moment of the right side of (21), divided by B0 , is at most (Cvρ|S|) under the closed measure.

证明
Lift the anchors periodically to ℝ^3 . Their distinct lifts remain separated by more than r once L>2r . For a point y and a_t=√1+t , packing disjoint balls of radius r/2 bounds the number of anchors in a ball of radius u by C(1+u/r)^3 . Summing in shells of width (r,a_t) , with the Gaussian weight, gives ∑_ a∈ D e^ -d(y,a)^2/[1000(1+t)] ≤C(1+(1+t)^ 3/2 r^ -3 ). For the torus expression, select a nearest lift of each anchor; it is bounded by the full lifted Gaussian sum just estimated. Only y in S can contribute after the distance indicator in (15), because the anchors are within Ds of U . Multiplication by w(t) now proves (21), since w(t)(1+t)^ 3/2 ≤C . This proof is deterministic for every set of separated anchors and therefore permits adaptive choices. The integral of the scalar weight on the right of (21) is at most C(1+δr^ -3 )≤B_0 . Divide by B_0 and regard the result as an average of the variables n_S(ω(t)) , padding with a zero variable if the total averaging mass is less than one. Jensen's inequality for the exponential, stationarity of the one-time closed law, and (11) at λ=1/2 give 𝔼_ cl [ B_0^ -1 C∫_0^ δ/2 (w(t)+r^ -3 )n_S(ω(t))\,dt ] ≤𝔼_Pe^ n_S ≤𝔼_Pe^ n_ φ_S ≤e^ C_vρ|S| . Time reversal gives the other half of the assertion.
