  1. theorem OAI.LittleFinitistic.SelectedCohomologyVanishing.module_isZero line 13

    Source documentation

    The three actual vertex functors jointly detect a zero module.

        (h : ∀ i : Fin 3, IsZero
          ((LeftVertexHomology.vertex k (B P) (ThreeVertexAlgebra.vertex (composition P) i)).obj M)) :

  2. theorem OAI.LittleFinitistic.SelectedCohomologyVanishing.cohomology_isZero line 32

    Source documentation

    Vanishing on all three evaluated representatives gives actual cohomology vanishing of the fixed selecting tensor as a B-module.

    theorem cohomology_isZero (n : ℤ)
        (h : ∀ v : Fin 3, IsZero ((SelectedTensor.source N v).homology n)) :
        IsZero ((SelectedTensor.complex N).homology n) := by
