Define s(A):= supn0rA (n) for each A {0}. Given any three numbers a, b, c {2, 3, 4,} {} satisfying max(a, b) 陇 c we prove that there exist two infinite disjoint subsets A, B of N such that for each n the nth el
for every sum-free set S, the representation function rs(n), and show that if rs(n) grows sufficiently quickly then the set of subsets of S has positive probability, and conversely, that if rs(n) has a sub-sequence with suitably slow growth, then the set of subsets of S has probabil...

Sum-Free Set A sum-free set is a set for which theintersectionof and thesumset is empty. For example, the sum-free sets of are , , , , , and . The numbers of sum-free subsets of for , 1, ... are 1, 2, 3, 6, 9, 16, 24, 42, 61, ... (OEISA007865)....
Proof. Assume that we have a set TT of size kk with only even numbers. Then, it is very obvious that the number of subsets with odd sum and even sum is 00 and 2k2k respectively. If we add an odd number into TT (now the size of TT is k+1k+1), then it is guaranteed that ev...
