摘要

Erdos conjectured that for any set A subset of N with positive lower asymptotic density, there are infinite sets B, C subset of N such that B + C subset of A. We verify Erdos' conjecture in the case where A has Banach density exceeding 1/2. As a consequence, we prove that, for A subset of N with positive Banach density (a much weaker assumption than positive lower density), we can find infinite B, C subset of N such that B+C is contained in the union of A and a translate of A. Both of the aforementioned results are generalized to arbitrary countable amenable groups. We also provide a positive solution to Erdos' conjecture for subsets of the natural numbers that are pseudorandom.
