Gauss-Kuzmin Probability Distribution Empirical vs Theoretical

The probability that coefficient $a_k = k$ follows $P(a_k = k) = -\log_2\left(1 - \frac{1}{(k+1)^2}\right)$.

Continued Fraction Recursive Tree Algebraic Anatomy

Any real number $x$ decomposes into integer parts and reciprocal remainders:

x = a₀ + 1 / (a₁ + 1 / (a₂ + 1 / (a₃ + ...))) π ≈ 3 + 1 / (7 + 1 / (15 + 1 / (1 + 1 / (292 + ...))))
Why Exceptions Fail:
  • Quadratic Irrationals (e.g. $\phi = [1; 1, 1...], \sqrt{2} = [1; 2, 2...]$): Periodic coefficients cause geometric means to lock onto algebraic values like 1.0 or 2.0.
  • Euler's $e = [2; 1, 2, 1, 1, 4, 1, 1, 6, ...]$: Arithmetic progression of coefficients causes geometric mean to grow like $(n!)^{1/n} \to \infty$.
  • Rationals ($355/113$): Terminate with finite terms; geometric mean stops updating.
Monte Carlo Measure-Theoretic Demonstration (100 Simultaneous Real Numbers) Lebesgue Measure = 1

Pick 100 random real numbers uniformly at random from $[0,1]$. While individual trajectories fluctuate wildly due to large coefficients (like 292 in $\pi$), their aggregate geometric means inevitably condense onto the singular line 2.685452...
