Generalized asymptotic Sidon basis

Abstract

Let $h,k\ge 2$ be integers. We say a set $A$ of positive integers is an asymptotic basis of order $k$ if every large enough positive integer can be represented as the sum of $k$ terms from $A$. A set of positive integers $A$ is called $B_h[g]$ set if all positive integers can be represented as the sum of $h$ terms from $A$ at most $g$ times. In this paper we prove the existence of $B_h[1]$ sets which are asymptotic bases of order $2h+1$ by using probabilistic methods.
