Calculation record

Test finite-propagation constraints on the full curved inverse dynamics.

The proof uses the complete unitary evolution and a local multiplication
operator. No positive-frequency projection or particle reassignment is used.

Research context

  • Causal constraint on reconstructed simplex dynamics

    An exact commutator on the actual curved spatial geometry proves that the reconstructed all-band polynomial dynamics have no finite propagation speed, while leaving open causal nonlinear dynamics with selected simplex particle frequencies.
