Abstract
Cameron and Erdos raised the question of how many maximal sum-free sets there are in {1,..., n}, giving a lower bound of 2^(n/4) . In this paper we prove that there are in fact at most 2^((1/4+o(1))n) maximal sum-free sets in {1,..., n}.
Our proof makes use of container and removal lemmas of Green as well as a result of Deshouillers, Freiman, Sos and Temkin on the structure of sum-free sets.
