Restricting the full commutator to the common radial-fit ball

  1. theorem OAI.RegularPointCoordinates.normalized_commutator_restrict line 19

    Source documentation

    The chosen fits only need to represent the radial derivatives on the smaller common ball. Restriction loses precisely the given volume ratio.
