Exact translation of the normalized probe generator chains

  1. theorem OAI.PolycyclicRecognition.CartanWordModel.probe_dilation_coordinate_norm line 22

    Source documentation

    The exact weight dilation preserves the coordinate bound when the reference template is translated by the pivot height.

    theorem probe_dilation_coordinate_norm {E : Set W} (hE : IsCompact E) (hne : E.Nonempty)
        (w : W) (β : M.Bases) (r : ℝ) (v : cartanRootIdeal H) :
        ‖(M.boxBasis T hunimod eW ((fun x => x + w) '' E) β r).equivFun
          (cartanIdealWeightDilation T H (r • cartanHeightSection T H (eW.symm w)) v)‖ =
          ‖(M.boxBasis T hunimod eW E β r).equivFun v‖ := by

  2. theorem OAI.PolycyclicRecognition.CartanWordModel.probe_dilation_coefficient_bound line 34

    Source documentation

    The same dilation translates the generator amplitude exponent exactly.

    theorem probe_dilation_coefficient_bound {E : Set W} (hE : IsCompact E) (hne : E.Nonempty)
        (w : W) (r t B : ℝ) (i : Fin M.letterCount)
        (ht : |t| ≤ B * Real.exp (r * (M.supportIn T hunimod eW).weightSupport E i)) :
        |t * Real.exp (r * M.weight i (cartanHeightSection T H (eW.symm w)))| ≤
          B * Real.exp (r * (M.supportIn T hunimod eW).weightSupport ((fun x => x + w) '' E) i) := by

  3. theorem OAI.PolycyclicRecognition.CartanWordModel.probe_dilation_generator_step line 59

    Source documentation

    Dilation carries each actual generator edge to the same letter with its explicitly rescaled coefficient.
