Source counts in the actual dilated ideal-section coordinates

  1. theorem OAI.PolycyclicRecognition.exists_dilated_section_probe_counts line 25

    Source documentation

    The original product probe measure, the moving scalar dilation, and fixed-pivot metric packing give one source exponent with a uniform positive constant. The retained mass is measured before choosing its base sample.
