ContinuousLinearMap.IsStarNormal.orthogonal_range

∀ {𝕜 : Type u_1} {E : Type u_2} [inst : RCLike 𝕜] [inst_1 : NormedAddCommGroup E] [inst_2 : InnerProductSpace 𝕜 E]
  {T : E →L[𝕜] E} [inst_3 : CompleteSpace E], IsStarNormal T → (↑T).rangeᗮ = (↑T).ker

The range of a normal operator is pairwise orthogonal to its kernel. This is a weaker version of LinearMap.IsSymmetric.orthogonal_range but with stronger type class assumptions (i.e., CompleteSpace).
