A polynomial continuity bound for the scale parameter

  1. theorem OAI.Ostmann.quadraticDensitySum_scale_sub_bound line 12
  2. theorem OAI.Ostmann.positiveQuadraticSum_scale_sub_bound line 78

    Source documentation

    Both original infinite series are replaced by the same support at Rmax; the finite scale estimate then applies without a cutoff error.
