    Source documentation

    An explicit classical Vaughan estimate for the actual von Mangoldt exponential sum. The only analytic input is a reduced rational approximation; all Type I and Type II cancellation estimates have been proved above.

  5. theorem OAI.Problem337.Vaughan.eventually_vonMangoldt_sum_log_bound line 121

    Source documentation

    The estimate holds uniformly in every reduced approximation once the summation length is large, with an absolute explicit constant.
