2875 — The Soft Translation Monodromy Is the Source Leray-Tube Pairing

Local pushed-forward form

At the labelled soft normal t=qg1/X1=0t=q_{g1}/X_1=0, the moving-fiber pushforward has local form

I(t) dt=Ldtt+holomorphic terms.I(t)\,dt = L\frac{dt}{t} + \text{holomorphic terms}.

The coefficient LL is the qg1q_{g1}-residue vanishing period, with the physical positive a=y23a=y_{23} occurrence selected from the full marked packet.

Leray tube

Use the source orientation fixed by

dqg1=dy12dq_{g1}=dy_{12}

and by the oriented positive Cayley–Menger chain. For a positive Leray loop τϵ\tau_\epsilon around t=0t=0,

∫τϵI(t) dt=2πiL.\int_{\tau_\epsilon}I(t)\,dt = 2\pi iL.

The value is independent of the tube radius. Reversing the residue orientation reverses both sides.

Translation monodromy

For the pointed primitive

P(t)=∫2tI(s) ds,P(t)=\int_2^t I(s)\,ds,

analytic continuation once around the same positive loop gives

ΔP=2πiL.\Delta P=2\pi iL.

Hence

ΔP=⟨source Leray tube,residue coefficient L⟩.\Delta P = \left\langle \text{source Leray tube}, \text{residue coefficient }L \right\rangle.

The affine translation of the logarithmic torsor is therefore not an untyped integration constant. It is exactly the source-normalized tube pairing.

Classification

Together with Entries 2871 and 2873, this completes the moving-cycle, regulator, and Leray-pairing gates for the soft logarithmic torsor.
