Stabilization of affine approximations across comparable scales

  1. theorem OAI.PolycyclicRecognition.affine_scale_labels_and_offsets line 16

    Source documentation

    Mixed concentration and the exact chart transition stabilize the finite labels. The offsets are compared in the physical source-scale normalization.
