Cumulative comparison for the actual pinching matrices

  1. theorem OAI.RegularPointCoordinates.central_comparison_rescale line 14

    Source documentation

    A positive rescaling of the central mass changes only the finite constant.

        (ht : 0 ≤ t) (hm : 0 ≤ mass) (hT : 0 ≤ T) (hc : 0 < c)

        H ≤ (T * (1 + c⁻¹)) * (t + c * mass) := by

  2. theorem OAI.RegularPointCoordinates.regular_patch_cumulative_comparison line 33

    Source documentation

    Actual raw masses, mean inverses and a strictly interior central heat scale satisfy both cumulative comparisons. All matrix changes and the reverse covering are derived from the constructed data.
