Q9 — Proof of the Lifting Hypothesis [H-lift]

This repository contains the source of the Q9 Cosmochrony paper Proof of the Lifting Hypothesis [H-lift].

The companion paper Q5b introduces Hypothesis [H-lift]: the operator $L_\Pi = -A\partial_k^2$ produced by Q5a as the Mosco limit of the admissibility forms $\mathcal{E}q$ is the image, under the Schrödinger representation $\pi_1$ at unit central character, of the kinetic sector of the sub-Laplacian $\Delta{\mathrm{Heis}}$ on $\mathrm{Heis}_3(\mathbb{R})$, restricted to the admissible subspace.

Core Result

This paper resolves Q5b Open Problem O1 by establishing [H-lift] under the admissibility-controlled spectral bound (from Q5a hypotheses [H1], [H2], [H-w], [H-E1], [C]). The Born–Infeld admissibility constraint forces the Mosco limit to select precisely the kinetic sector of $d\pi_1(\Delta_{\mathrm{Heis}})$.

The mechanism: the modulation generator $\rho_q(X)$ contributes a position-energy term that vanishes at rate $O(q^{-1})$ (interplay of the $O(q^{-2})$ phase-oscillation factor and the $O(q)$ discrete position spread controlled by the BI bound), while the shift generator $\rho_q(Y)$ contributes the surviving kinetic term $|\partial_k f|^2$.

As a consequence, Q5b Theorems 5.2 and 6.1 (effective metric and Lorentzian signature) become conditional only on the Q5a hypotheses, not on the independent hypothesis [H-lift].
