The Structure That Survives

The collision invariant is the part of the arithmetic that remains when everything else has been allowed to move. This essay explains the name and the analogy to noble gases.

The Analytic Collision Transform

The Analytic Collision Transform

The same finite diagonal geometry now carries an exact identity at every s in the critical strip. The analytic factors move. The collision content does not.

The Collision Spectrum and the L-Function Landscape
avoidance

The Collision Spectrum and the L-Function Landscape

The Fourier coefficients factor through Bernoulli numbers and diagonal character sums. The collision weight encodes L-function values at s=1. The digit function meets the critical strip.

The Spectral Repulsion

Forty percent of the expected overlap between collision weights and prime character sums is missing. The ratio is stable across every prime base from 3 to 37.

The Double Transversality

The Double Transversality

The collision invariant and the prime distribution avoid each other across the strip. The avoidance persists at every lag, across every base tested.

The General Neutrality Theorem

The General Neutrality Theorem

Neutrality holds at every odd prime, not just 3. The same reflection identity, the same vanishing, at every scale. The anti-correlation between collision weights and prime sums is universal.

The Neutrality Theorem
collision

The Neutrality Theorem

The mod-3 component of the collision transform vanishes. Remove it and the sum explodes. Neutrality is not decorative. It is structural.

The Collision Transform and the Critical Strip

The centered sum converges at s=1. Push it below. The penetration depth measures how far into the critical strip the collision signal survives.

The Collision Periodic Table
collision

The Collision Periodic Table

Forty integers, determined by the last two digits of every prime past 100. Every complement pair sums to exactly -1. At base 12, the table sorts musical intervals by tension.
