Uniform fixed-coefficient two-form estimate (equation (6))

  1. theorem OAI.JointDickman.coefficient_two_form_bound line 15

    Source documentation

    The fixed rough coefficient contributes only a bounded Euler factor; all dependence on the nonzero positive slope is through the singular factor.
