Constants Alpha Precision Gap Correction Positive

The positivity lemma

The fine-structure constant α is a number that measures the strength of electromagnetic interactions between charged particles, roughly 1/137. In the Recognition Science framework, a construction for its inverse starts with a seed value of 44π, about 138.23, and then applies a correction. The correction is an exponential factor: it multiplies the seed by exp(−w·ln(φ)/seed), where φ is the golden ratio and w is a positive parameter. The declaration gap_correction_positive proves that this correction factor is always a positive number whenever both the seed and the parameter w are positive.

This is a simple mathematical fact. The exponential function never returns zero or a negative number for any real input, so multiplying a positive seed by a positive exponential factor must yield a positive result. The proof in the machine-checked library of formal theorems is correspondingly short: it unfolds the definition and applies the known positivity of the exponential function. The theorem is stated with full generality, for any positive w and any positive seed, not just for the specific values used in the alpha construction.

The lemma matters because the construction's final number is the product of the seed and this correction. Knowing the correction is positive means the assembled expression cannot accidentally cross zero or flip sign. The certificate structure AlphaPrecisionCert bundles this positivity with other basic facts about the seed and curvature correction, and the theorem alpha_precision_cert_exists shows such a certificate can always be produced. This is groundwork: it establishes that the construction is well-behaved, not that it matches any particular measured value.

In Recognition Science, the assembled expression for the inverse fine-structure constant is proved to lie in a band about 60 ppm wide, from 137.030 to 137.039. The CODATA 2022 measured value is 137.035999177(21), which falls inside that band. But the positivity lemma itself makes no claim about agreement with experiment. The seed 44π is an identification, not a derived coupling, and the exact value of the inverse fine-structure constant at zero is treated as a free boundary datum within the framework. The lemma only guarantees that the correction factor stays positive, a necessary condition for the construction to be coherent at all.

What this page does not claim

The positivity lemma does not claim the construction matches the measured fine-structure constant. The lemma does not derive the seed value 44π from more basic principles. The lemma says nothing about the exact value of the inverse fine-structure constant at zero.

Verify this page

Every tagged claim above names its theorem. To check one yourself rather than trust this page, elaborate the source module with Lean 4 and audit its axiom basis:

expected axiom basis: [propext, Classical.choice, Quot.sound] (the Lean kernel's standard three; no RS-specific axioms)

A page whose claims cannot be reproduced this way does not ship. In production, every anchor links to the exact declaration in the public source release, and this block carries the build receipt for the page itself.
