One finite coarse-scale mass bound for every center

  1. theorem OAI.RegularPointCoordinates.dyadicBochnerMass_le_total line 18

    Source documentation

    The total full Bochner measure bounds the scaled mass at any center.

  2. theorem OAI.RegularPointCoordinates.exists_uniform_mass_background line 31

    Source documentation

    The finitely many omitted scales have a single finite background constant, independent of the ball center.
