Scale-invariant decrement constants for one fixed cutoff

  1. theorem OAI.RegularPointCoordinates.exists_scaled_supported_heat_bound_at line 23

    Source documentation

    With fixed cutoff support, Gaussian constants give a common two-sided decrement constant before choosing the harmonic column, its full Bochner measure, the pole or the cutoff. This order permits subsequent mass absorption.
