Replacing a top's carrier by its angular child-center carrier costs only the child width, not the width of an earlier block ancestor.

  2. theorem OAI.LipschitzHilbert.carrier_replacement_motion line 27

    Source documentation

    A bound in the top carrier transfers to the one common child carrier.

    Source documentation

    At the source averaging scale the carrier replacement is of order G^(-1/2), uniformly in the absolute frequency center.
