The Character Structure of the Collision Fluctuation

The Character Structure of the Collision Fluctuation

The collision fluctuation drifts at the Mertens rate. Split it by character, and four currents appear.

Bin Derangements and the Gate Width Theorem

Bin Derangements and the Gate Width Theorem

Nine deranging multipliers at every prime in base 10. The count does not depend on the prime.

The Coherence Decomposition

The Coherence Decomposition

When the alignment is high, why is it high? Signal and background come apart cleanly.
