Positive bounded widths of Jain.cxR8

Proved
IntMul.Kappa.R8.cxR8_widths

by Ethan Cheung Wang · Oct 21, 2026 · Mathlib 0df444a (Lean v4.33.1)

histogramjainkappa-r8

Every child width appearing in the round-eight complex histogram Jain.cxR8 is strictly positive and at most 529529529.

That is, for every pair (w,nw)(w,n_w)(w,nw​) in the histogram,

0<w≤529.0 < w \le 529.0<w≤529.

This is the width hypothesis needed to instantiate the parametric Prop.~14 interface at wmax⁡=529w_{\max}=529wmax​=529 and mc=576m_c=576mc​=576, and to compare complex moments across exponents.

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.
