Resolvent expression and strong continuity of the bounded transform

  1. theorem OAI.KadisonKastler.rational_transform_complex line 16
  2. theorem OAI.KadisonKastler.kaplanskyTransform_eq_resolvents line 39

    Source documentation

    Two resolvents express the bounded real rational transform.

    theorem kaplanskyTransform_eq_resolvents (a : H →L[ℂ] H) (ha : IsSelfAdjoint a) :
        cfc kaplanskyTransform a = -resolvent a Complex.I - resolvent a (-Complex.I) := by

  3. theorem OAI.KadisonKastler.tendsto_kaplanskyTransform_of_strong line 63

    Source documentation

    Bounded-transform strong continuity requires only self-adjointness, not a bound on the original net.
