The Theory of Persistence

PT calculators

Three interactive tools for working with the arithmetic cascade of the sieve. Everything runs in the browser, in plain JavaScript, with no dependency.

Calculator 1

γp(μ) — anomalous dimensions and activity

Canonical formula (T6): γp = 4·qp−1·(1−δp) ÷ (μ·δp·(2−δp)) with q = 1 − 2/μ and δp = (1−qp)/p. A prime is active if γp > s = 1/2.

sin²(θp) — holonomy on both branches

Algebraic identity (T6): sin²(θp) = δp·(2 − δp). Branch q+ = 1 − 2/μ (couplings, leptons, αEM); branch q = e−1/μ (geometry, quarks, CKM).

αEM — from bare product to dressed value

Computed at μ* = 15, branch q+. The BA5 product αbare = ∏ sin²θp over {3, 5, 7} gives 1/136.28. Dressing through the binary channel p = 2 closes the gap to 1/137.036.
