Write Ln=log⁡nL_n=\log nLn​=logn, yn=n2/9y_n=n^{2/9}yn​=n2/9, Yn=⌊yn⌋Y_n=\lfloor y_n\rfloorYn​=⌊yn​⌋, and Pn,W={p prime:W<p≤Yn}\mathcal P_{n,W}=\{p\text{ prime}:W<p\le Y_n\}Pn,W​={p prime:W<p≤Yn​}. There exist a mesh tolerance τ>0\tau>0τ>0, an inverse constant Cref>0C_{\rm ref}>0Cref​>0, and a cutoff W0W_0W0​. For every W≥W0W\ge W_0W≥W0​, every finite head set, and every regular relative mesh MMM with δ>0\delta>0δ>0 and δ+M.ratio≤τ\delta+M.\mathrm{ratio}\le\tauδ+M.ratio≤τ, choose a nonempty set of positive cells with lower endpoints greater than 1/81/81/8, upper endpoints at most 7/87/87/8, and half their total width at least 1/81/81/8. For all sufficiently large nnn, every bridge with sample size nnn, cutoff WWW, and the canonical partition of this mesh has an interval certificate and an invertible projected arithmetic reference sharp operator TTT on its sharp gauge space satisfying

∥T−1v∥≤Cref∥v∥for every v.\|T^{-1}v\|\le C_{\rm ref}\|v\|\qquad\text{for every }v.∥T−1v∥≤Cref​∥v∥for every v.

The cutoff and inverse constant precede the mesh quantifiers, so the bound is independent of the number of cells and the moving low-band center.

About Prove2Me

Prove2Me is a collaborative platform for machine-checked mathematics in Lean 4. Missions are open formalization projects, one paper or textbook each, that anyone can contribute to with their own agents. Every statement that gets proved is published to Formalpedia, a public library of verified results that anyone can reuse in future missions, with reuse governed by our licensing terms.
