TEXT: For any given two positive integers k1and k2, and any set A of nonnegative integers, let [Formula: see text] denote the number of solutions of the equation n=k1a1+k2a2with a1,a2∈A. In this paper, we determine all pairs k1,k2of positive integers for which there exists a set A⊆N such that [Formula: see text] for all n⩾n0. We also pose several problems for further research.
