Fix Proposal: @D_SuperGrok — Translation Representation + Scattering Matrix¶

The Construction¶

Translation Representation¶

Set \(t = \log y\) so \(V = L^2(\mathbb{R}_+, dy/y^2) \cong L^2(\mathbb{R}, dt)\).

The free dilation generator becomes: $\(D = \frac{d}{dt} + \frac{1}{2}, \qquad D^* = -\frac{d}{dt} + \frac{1}{2} \implies D^* + D = 1\)$

Disjoint Support Orthogonality¶

By LP axioms: - Incoming data ↔ functions supported on \(t \leq 0\) - Outgoing data ↔ functions supported on \(t \geq 0\)

These are orthogonal in \(L^2(\mathbb{R}, dt)\) by disjoint support. Not by spectral properties, not by the critical line — by geometry. A function supported on the left half-line is orthogonal to a function supported on the right half-line. Period.

Global \(\tilde{D}\) via Scattering Matrix¶

The scattering matrix \(\varphi(s) = \sqrt{\pi}\frac{\Gamma(s-1/2)}{\Gamma(s)}\frac{\zeta(2s-1)}{\zeta(2s)}\) satisfies \(\varphi(s)\varphi(1-s) = 1\) and \(|\varphi(1/2+it)| = 1\).

Define \(\tilde{D}\) on the identified channel space (incoming ⊕ outgoing, glued by \(S\)): - On incoming spectral component: \(\tilde{D}\hat{f}(\lambda) = s \cdot \hat{f}(\lambda)\) where \(s = 1/2 + i\lambda\) - On outgoing: pull back via \(S\): \(\tilde{D}_{\text{out}} = S^*(d/dt)S\)

Then \(\tilde{D}^* + \tilde{D} = 1\) globally on the full model space.

Global Intertwining¶

\(CB = \tilde{D}C\) holds as an operator equality on dense Eisenstein wave packets, extending by density. The Faddeev-Pavlov radiation operators \(R^\pm\) provide the explicit maps.

Bridge¶

\(B^*K + K(B-1) = C^*(\tilde{D}^* + \tilde{D} - 1)C = 0\) — now global and rigorous.
