Canonical height after choosing the endpoint metrics

  1. theorem OAI.PolycyclicRecognition.exists_canonical_height_model_with_metric_choice line 17

    Source documentation

    The triangular model and height space can be fixed before the endpoint metrics. Thus a subsequently chosen minimizing-path metric retains both the quasi-isometry comparison and the proved canonical-height Lipschitz bound.
