Fibonacci Modulation and Geometric Protection.pdf
The relational transfer matrix of the URCL contains a pairwise factor kappa_ij that the framework calls geometric protection. This factor is built from Fibonacci numbers and the golden ratio.
The present article explains the classical mathematics of the Fibonacci sequence and the golden ratio, states Hurwitz's theorem on best approximations, and then shows how the URCL assembles these ingredients into the protection term kappa_ij.
The Fibonacci sequence is defined by the recurrence
F_0 = 0,
F_1 = 1,
and
F_n = F_(n-1) + F_(n-2), for n >= 2.
The first few terms are:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
It is a classical theorem that the ratio of consecutive Fibonacci numbers converges to the golden ratio:
limit as n tends to infinity of F_(n+1) / F_n = phi = (1 + sqrt(5)) / 2 approximately equal to 1.6180339887...
The golden ratio is the unique positive real number satisfying
phi = 1 + (1 / phi),
