For every c>C0c>C_0c>C0​ and natural depth d≥201d\ge201d≥201, there exists a cutoff W0W_0W0​ such that every W≥W0W\ge W_0W≥W0​ satisfying W≥2W\ge2W≥2, W≥2d+1W\ge2d+1W≥2d+1, and the public reciprocal-sum and actual-moment cutoffs has the following property. For any 1<r0<3/21<r_0<3/21<r0​<3/2 and paper combined-tangent exponent δ∗\delta_*δ∗​ for (c,W,r0)(c,W,r_0)(c,W,r0​), a combined-charge terminal at depth ddd yields the synchronized top-frozen Section 9 analytic completion at the same (c,d,W,r0,δ∗)(c,d,W,r_0,\delta_*)(c,d,W,r0​,δ∗​):

CombinedChargeTerminal⁡(c,δ∗,d)⟹SynchronizedAnalyticCompletion⁡(c,d,W,r0,δ∗).\operatorname{CombinedChargeTerminal}(c,\delta_*,d)\Longrightarrow\operatorname{SynchronizedAnalyticCompletion}(c,d,W,r_0,\delta_*).CombinedChargeTerminal(c,δ∗​,d)⟹SynchronizedAnalyticCompletion(c,d,W,r0​,δ∗​).

The completion consists of a regular mesh, a family of bridges eventually at index nnn and cutoff WWW, a multiplicity, positive tangent and reserve constants, and a synchronized post-height fitting input. Its active masses satisfy qn≤Cqsnq_n\le C_qs_nqn​≤Cq​sn​, its post-fit bound satisfies (2/9)CpostCq≤Ctan(2/9)C_{\rm post}C_q\le C_{\rm tan}(2/9)Cpost​Cq​≤Ctan​, and its mesh obeys the ratio-cell width bound for ratio 21/2021/2021/20. The mesh tolerance is chosen before WWW, and the numerical and analytic constants are chosen before the final mesh.

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, licensed under Apache 2.0.
