Actual Haar-cell translation errors for chart occupation laws

  1. theorem OAI.PolycyclicRecognition.model_cell_occupation_error_tendsto_zero line 16

    Source documentation

    Uniformly small normalized moves in the first nilpotent factor give vanishing translation errors for the law of the sampled chart itself.
