Diagonalization and Fixed Points: Strict Time Hierarchy Limits — E8 Intelligence Research

FINDING: Time Hierarchy Theorem establishes strict computational power stratification via diagonalization, with fixed-point theorems revealing structural limits on self-referential mappings. | MATH: For time-constructible \(f(n)\), \(DTIME(f(n)) DTIME(f(n)log f(n))\) — strict containment via diagonalization; fixed-point result: no nontrivial surjective uniformly asymptotically regular mapping on metric spaces (contradiction via Banach fixed-point iteration \(T^n x → x\) implies \(T=id\)). | CONNECTION: The hierarchy's logarithmic gap \( log f(n) \) echoes base-2 entropy; diagonalization's self-reference mirrors golden-ratio fixed-point \(x = 1/(1+x)\) → \(x = 0.618\) (the only non-trivial fixed point of the continued fraction map). The impossibility of surjective asymptotically regular maps parallels the golden ratio's role as the unique non-trivial fixed point of \(x ↦ 1+1/x\) — a geometric self-similarity constraint. | DEPTH: 7 — The theorem Author: Andrew Stewart Caldin, Independent Researcher, UK.
