The uniform quantifier step for actual front passages. A compactness argument need only produce an eventual positive success probability along one strictly increasing subsequence of each vanishing-mesh sequence.

  1. theorem OAI.SLEExactGauge.uniform_passage_threshold_of_subsequences line 18

    Source documentation

    The diagonal obstruction to a uniform passage estimate persists along all subsequences, so compactness need only control one of them.

  2. theorem OAI.SLEExactGauge.FirstFrontPassage.lt_before_firstFrontTime line 56

    Source documentation

    Before an attained first hit, a continuous coordinate that started below the front remains strictly below it.

  3. theorem OAI.SLEExactGauge.PassageSuccess.frontSuccess_source_prefix line 78

    Source documentation

    The open-envelope success event gives exactly the strict pre-front containment used by the manuscript. The front point itself is specified separately by its attained coordinate and terminal offset.

  5. theorem OAI.SLEExactGauge.PassageSuccess.frontPassageProbability_antitone line 109

    Source documentation

    Increasing the required mass only decreases the concrete passage probability; no probability or measurability assumption is needed here.

  6. theorem OAI.SLEExactGauge.PassageSuccess.frontPassageProbability_mono_start line 122

    Source documentation

    A later retained starting point gives a subset of the full passage success-and-mass event. This removes the auxiliary first-height stop from the final one-step conclusion.

  8. theorem OAI.SLEExactGauge.PassageSuccess.uniform_frontPassage_probability_of_subsequences line 147

    Source documentation

    Once actual conformal compactness and the sequence passage theorem supply the subsequential estimate, the full uniform passage constants follow for the original concrete success-and-mass event.
