For a symmetric tensor , set
Write
The inherited formulas are
Here is the divergence-form scalar operator appearing in the formula for , with replaced by . By XII-E's affine slot identity,
No lower coefficient or additional metric slot has been inserted.
Put
The last equality uses the polarization of the already fixed quadratic response. It is not a newly selected response or co-transformation; .
Define the explicit quadratic derivatives
