I'd really like some help in answering the next question...anything that might help will save my life:
F is defined this way: F:A→B where A,B⊂P(N) and P(N) is the power set of the naturals.
Let S,R∈A such that S is a proper subset of R if and only if F(S) is a proper subset of F(R)
My question is to prove whether or not there is an F from P(N)∖N to P(N) which is also a surjective function?
