Hyperbolic Geometry and the Golden Ratio in Farey Sequence Statistics — E8 Intelligence Research
FINDING: Farey sequences and Ford circles reveal that rational points on the unit interval (and their 2D circle analogues) exhibit universal fine-scale statistics governed by hyperbolic geometry and lattice equidistribution, with the golden ratio emerging as the extremal spacing constant. MATH: - Farey sequence \\(F_N\\): all reduced fractions \\(p/q \\in [0,1]\\) with \\(q \\le N\\). - Ford circle at \\(p/q\\): radius \\(1/(2q^2)\\), tangent to neighbors; total circle length sum diverges as \\(\\sum_{q\\le N} 1/q \\sim \\log N\\). - Gap distribution for Farey fractions: normalized gaps \\(\\delta_i = (F_{i+1} - F_i) \\cdot N^2\\) converge to a limiting distribution with density \\(12/(\\pi^2 \\delta^3)\\) for large \\(\\delta\\), and mean gap \\(\\to 1\\). - Golden ratio connection: the *maximal* gap in \\(F_N\\) occurs between consecutive fractions whose mediant is the golden ratio conjugate \\(\\phi^{-1} = (\\sqrt{5}-1)/2 \\approx 0.618\\) — specifically, the largest gap is bounded by \\(1/(\\sqrt{5} N^2)\\), achi Author: Andrew Stewart Caldin, Independent Researcher, UK.
