  1. lemma OAI.GammaFPP.lower_le_limit_integral_of_ae_eventually line 15

    Source documentation

    Fatou needs only eventual lower bounds, not samplewise convergence.

  2. lemma OAI.GammaFPP.latticeDistance_zero_nsmul line 39

    Source documentation

    Literal lattice L1 distance scales under natural multiplication.

    lemma latticeDistance_zero_nsmul (z : Vertex) (n : ℕ) :
        latticeDistance 0 (n • z) = n * latticeDistance 0 z := by
    …
  3. theorem OAI.GammaFPP.GammaEnvironment.directionalMeanConstant_linear_lower line 47

    Source documentation

    The actual Fekete mean limit has the same positive linear lower bound as the eventual path metric. The zero direction is treated before division.

    theorem GammaEnvironment.directionalMeanConstant_linear_lower
        (h : GammaEnvironment shape rate P τ) (hs : 0 < shape) (hr : 0 < rate)
        (z : Vertex) :
        cheapSlope shape rate * (latticeDistance 0 z : ℝ) ≤ directionalMeanConstant h hs hr z := by
