  5. theorem OAI.GammaFPP.tendsto_nat_right_multiple line 56

    Source documentation

    Cofinality of positive natural multiples, proved without a real-index limit.

    private theorem tendsto_nat_right_multiple (k : ℕ) (hk : 0 < k) :
        Tendsto (fun n : ℕ => n * k) atTop atTop := by
    …
  6. theorem OAI.GammaFPP.GammaEnvironment.directionalMeanConstant_nsmul line 67

    Source documentation

    Natural homogeneity follows from the cofinal subsequence n*k, not an assumed homogeneous extension. The zero multiplier is a separate case.

    theorem GammaEnvironment.directionalMeanConstant_nsmul
        (h : GammaEnvironment shape rate P τ) (hs : 0 < shape) (hr : 0 < rate)
        (z : Vertex) (k : ℕ) :
        directionalMeanConstant h hs hr (k • z) =
          (k : ℝ) * directionalMeanConstant h hs hr z := by

  7. theorem OAI.GammaFPP.GammaEnvironment.directionalMeanConstant_zsmul line 97

    Source documentation

    Integer homogeneity, with |k| represented by its exact natural absolute value. This includes k=0, negative multipliers, and the zero direction.

    theorem GammaEnvironment.directionalMeanConstant_zsmul
        (h : GammaEnvironment shape rate P τ) (hs : 0 < shape) (hr : 0 < rate)
        (z : Vertex) (k : ℤ) :
        directionalMeanConstant h hs hr (k • z) =
          (k.natAbs : ℝ) * directionalMeanConstant h hs hr z := by
