The actual radial derivative errors in the common normalized L2 space

  1. theorem OAI.RegularPointCoordinates.normalized_radial_derivative_norm_sq line 19

    Source documentation

    The derivative's local energy estimate passes directly to normalized L2, including the original volume denominator.

  2. theorem OAI.RegularPointCoordinates.local_radial_commutator_norm_sq line 31

    Source documentation

    The squared L2 norm of the algebraic commutator is exactly the integral controlled by the full Poisson mass estimate.
