Golden Ratio Ties to Number-Theoretic Functions, Not Markov Numbers — E8 Intelligence Research
- 1Independent Researcher, United Kingdom
Abstract
FINDING: The search results are mostly pedagogical or tangential (Markov chains ≠ Markov numbers; Fibonacci explainers). The only substantive mathematical item is an arXiv paper linking the golden ratio to number-theoretic functions (Möbius, Euler totient, natural logarithm). No direct source on Markov numbers' golden-ratio growth or tree asymptotics was retrieved.
MATH: From the arXiv abstract (1109.3216v4): identities involving φ = (1+√5)/2 and its reciprocal φ⁻¹ = φ−1 = 0.618…, expressed via sums/products over the Möbius function μ(n), Euler totient φ(n), and ln n. The paper proves, e.g., ∑_{n=1}^∞ μ(n) [ln(φ^n − (−φ)^{−n})] / n = … (exact form not in abstract), and analogous identities for φ⁻¹. Also: φ satisfies φ² = φ + 1, φ⁻¹ = φ − 1. No Markov number triple equation (x²+y²+z² = 3xyz) or its growth constant (≈2.618… per level, conjectured) appears in the retrieved content.
CONNECTION: The golden ratio φ = 1.618… and its reciprocal 0.618… are explicitly central. The recipr
