Radius control for logarithmic-error paths

The support-path parameter bounds imply a single linear ambient ball bound for every sample, uniformly at all scales at least one.

  1. theorem OAI.PolycyclicRecognition.PathMetricBound.dist_source_le line 17

    Source documentation

    A coarse path stays within its speed plus its additive error of its source.

    theorem PathMetricBound.dist_source_le {p : Path x y} {L κ : ℝ}
        (h : PathMetricBound p L κ) (hL : 0 ≤ L) (t : unitInterval) :
        dist x (p t) ≤ L + κ := by

    Source documentation

    The logarithmic error is uniformly at most a linear error for r ≥ 1.

    theorem PathMetricBound.dist_source_le_linear {p : Path x y} {C r : ℝ}
        (h : PathMetricBound p (C * r) (C * (1 + Real.log (2 + r))))
        (hC : 0 ≤ C) (hr : 1 ≤ r) (t : unitInterval) :
        dist x (p t) ≤ (4 * C) * r := by
