Calculation record
Nonlinear linked moduli on the actual ordinary normal plane.
Fourier collocation uses phi=k*theta, exploiting only the exact rotational
symmetry of P=z^d+a*z^(d-k). The spatial equation and both linked coefficients
remain present. The tube weight is evaluated after solving the planar rule.
Research context
- Curvature forces on the linked mass-carrier geometry
The actual tube weight gives an exact leading restoring-to-metric ratio, but also a centered shape force; the symmetric planar profile is not a complete curved stationary source.
Interpret numerical checks within the assumptions and limitations documented in these notes.
