The quotient trace in the per-tile volume exponent

  1. theorem OAI.PolycyclicRecognition.subexponential_exp_error line 15

    Source documentation

    A vanishing error in the exponent contributes a subexponential factor.

  2. theorem OAI.PolycyclicRecognition.section_tile_volume_exponent line 33

    Source documentation

    The ideal exponent and the exact quotient multiplier combine to P - ell. Arbitrary translated quotient locations are allowed.
