Smoothing atlases whose actual centers index prescribed neighborhoods.

  1. theorem OAI.ClosedSurfaceR4.FiniteOrderSmoothing.exists_smoothingAtlas_subordinate_locally_one line 16

    Source documentation

    The finite atlas retains the point indexing of prescribed neighborhoods. Its outer cutoffs equal one on a neighborhood of every weight-support point.

        (hV : ∀ p, IsOpen (V p)) (hpV : ∀ p, p ∈ V p) :
        ∃ A : SmoothingAtlas M,
          (∀ i : A.centers, tsupport (A.weight i) ⊆ V (i : M)) ∧
          ∀ (i : A.centers) (x : M), x ∈ tsupport (A.weight i) →
            A.outer i =ᶠ[𝓝 x] (fun _ => 1) := by

  2. theorem OAI.ClosedSurfaceR4.FiniteOrderSmoothing.exists_smoothingAtlas_subordinate line 56

    Source documentation

    The finite atlas weights are subordinate to their actual centers' prescribed open neighborhoods.
