Seven-row theorem
The 5z coefficient and complete leading assembly › Seven-row theorem · lines 1890–1922
| Mechanism | Verdict |
|---|---|
| Rows and , zeroth-incidence first derivative | Exact algebraic cancellation. |
| Nominal order-two master coefficient | Vanishes by even-profile parity. |
| Nominal inverse-quartic coefficient | Vanishes after exact signed internal reduction. |
| Positive- inner-tip delta and response cubic term | Cancel by the cone fundamental solution identity. |
| Collected inverse-cubic seven-row coefficient | Survives; detected in Section sec:obstruction. |
| Raw weak distributional limit | Does not exist. |
| Leading-subtracted finite part | Not established. |
The cancellation in (eq:tip-cancellation) removes an explicit incidence term from one representation. It does not make the surviving spatial-Laplacian distribution zero, and it does not amount to a canonical restriction of the complete coefficient to .
