Web1 Answer. From a category perspective, the natural definition for T to be invertible here is that there exists S ∈ L ( W, W) such that S ∘ T = T ∘ S = I. As usual, S ∘ T = I implies that T is injective, and T ∘ S = I entails that T is surjective. So T invertible implies it is bijective. Now assume that T is bijective.
