Supported subsequential laws of the actual neighboring cell samples

  1. theorem OAI.PolycyclicRecognition.CartanWordModel.exists_supported_neighbor_law line 29

    Source documentation

    Compact containment gives a convergent subsequence of the original translated Haar laws and a supported pair. The law is built from the actual map q ↦ (profile q, profile (q * step)).
