Calculation record
Actual normal-mode integrals and a full finite-band stability criterion.
Research context
- A stationary collective source for the spatial mass operator
A completed-square collective action makes the occupied geometric source stationary, preserves the finite carrier's frequencies and canonical energy, and has a controlled stable linear response across all maintained sector controls; its physical spatial completion and coupling vertices remain distinct questions.
