  2. theorem OAI.Problem337.reciprocal_phase_uniform_of_terminal line 25

    Source documentation

    For a bounded range of reciprocal-phase numerators, fixed-order terminal estimates give one positive power saving uniformly in the numerator and interval. All analytic hypotheses are confined to the explicit terminal estimate.
