Summary

The universal operator H_∞ on L²(Char(L)). At τ-effective cutoff N: H_{≤N} = P_{≤N} ⊙ H_∞ ⊙ P_{≤N}. All L-functions unified as spectral determinants: L_{≤N}(s,π) = det(I − s⁻¹ H_{π,≤N}). Riemann ζ, Dirichlet L, etc. as special cases.

Statement

%
\label{def:universal-operator}
The \textbf{universal operator}
$H_\infty : \mathcal{H} \to \mathcal{H}$
is the unbounded self-adjoint operator
on $L^2(\mathrm{Char}(\Lemniscate))$
defined on the character basis by:
\begin{equation}\label{eq:ch11-h-infty-action}
    H_\infty \, \chi_{(m,n)}
    \;=\;
    \sum_{(m', n') \in \mathbb{Z}^2}
    h_{(m,n),(m',n')} \;\chi_{(m',n')},
\end{equation}
where the matrix elements are determined
by the primorial tower:
\begin{equation}\label{eq:ch11-matrix-elements}
    h_{(m,n),(m',n')}
    \;=\;
    \lim_{d \to \infty}\;
    \frac{1}{M_d}
    \sum_{t \in (\mathbb{Z}/M_d\mathbb{Z})^\times}
    \chi_{(m,n)}(t) \;\overline{\chi_{(m',n')}(t)}\;
    \rho_d(t),
\end{equation}
with $\rho_d(t)$ the progression operator at depth~$d$
and $M_d = p_1 \cdots p_d$ the $d$-th primorial.
