  1. theorem OAI.Problem337.ThreePrimeAnalysis.norm_integral_cubic_majorArc_error_logbudget line 12

    Source documentation

    Explicit logarithmic budget for the cubic approximation error. A cutoff and radius of logarithmic size cost two powers of the logarithmic parameter.

  2. theorem OAI.Problem337.ThreePrimeAnalysis.tendsto_majorArc_log_error_factor line 44

    Source documentation

    The logarithmic major-arc error factor tends to zero whenever the approximation saves more than twice the logarithmic cutoff exponent.

  3. theorem OAI.Problem337.ThreePrimeAnalysis.eventually_norm_integral_cubic_majorArc_error_le line 55

    Source documentation

    Uniform little-o form, with all arc sets and complex approximants quantified after the threshold. This consumes pointwise approximation estimates but does not assert any prime-distribution estimate.

  4. theorem OAI.Problem337.ThreePrimeAnalysis.cubic_majorArc_error_isLittleO line 79

    Source documentation

    Function-valued little-o conclusion for a moving major-arc set. The complex integral error is negligible compared with the quadratic main-term scale.
