The Critical Line Is the Equal-Weight Locus of the Two Additive Tate Lifts
Scope correction: this is a local archimedean theorem. Entry 3952 shows that the odd lift is not a second global channel of the trivial zeta character.
The relative multiplier of the odd and even archimedean Tate lifts is
For ,
Hence, within , the two parity channels have equal weight if and only if . The two open half-strips are opposite dominance chambers, and the critical line is their unique equal-weight wall.
This gives a local explanation of the half-offset without using zero locations. It does not prove RH: the remaining theorem must show that a source-authorized scalar zero requires equality of the two parity-channel weights.
