Calculation record

Check the fixed-norm eigenvalue shift of the positive response model.

Research context

  • Fixed-norm response as an eigenvalue contribution

    A canonical-norm constraint converts the positive response force into a standing-frequency shift; equal-norm frozen source controls do not follow the simplex spectrum, while dynamically determined amplitudes and profiles remain open.
