WebSurjective means that every "B" has at least one matching "A" (maybe more than one). There won't be a "B" left out. Bijective means both Injective and Surjective together. Think of it as a "perfect pairing" between the sets: every one has a partner and no one is left out.

We show that, if \varphi is a surjective L^p-isometry on the set of rank one idempotents, then it leaves the set of rank one projections invariant.

"Injection" makes sense in a concrete category, namely a category C equipped with a faithful functor F: C → Set: a morphism f is an injection if F ( f) is an injection (equivalently, a monomorphism). Faithful functors always reflect monomorphisms: if F ( f) is a monomorphism, then so is f. The proof is straightforward.
