2559 — Reciprocal Tate Anomaly Lines Have an Exact Invariant Pairing

The finite-place transition obeys

$$\gamma_p(1-\bar s)={1\over\overline{\gamma_p(s)}}.$$

Consequently the pairing

$$\mathcal P_X(x,y)=x\bar y$$

between reciprocal cutoff lines is preserved exactly by every pair of bonding maps. Off-seam expansion in one metric and contraction in the other therefore do not destroy the relationship: the two lines are dual metric polarizations.

The pairing is perfect and nowhere zero on transported nonzero vectors. It is therefore a transition unit, not the distinguished zero-bearing section. The Riemann divisor must arise from an additional source-derived incidence state.

Scope

This is an exact finite-cutoff pairing theorem. It does not construct the archimedean incidence, prove its cutoff covariance, or confine zeros.
