Websurjective since it is the composition of two surjective maps. By Lemma 12.7 the existence of a surjective map from Nto B implies that B is countable. Uncountable sets are easy to come up with. Example13.2. By Cantor’s theorem there is no surjective map from the set Nof natural numbers to its power set P(N). Therefore P(N) is uncountable.

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. medtronic crm products

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.
