For a set A of nonnegative integers the representation functions R2(A,n), R3(A,n) are defined as the number of solutions of the equation n=a+a′,a,a′∈A with a<a′, a⩽a′, respectively. Let D(0)=0 and let D(a) denote the number of ones in the binary representation of a. Let A0be the set of all nonnegative integers a with even D(a) and A1be the set of all nonnegative integers a with odd D(a). In this paper we show that (a) if R2(A,n)=R2(N∖A,n) for all n⩾2N−1, then R2(A,n)=R2(N∖A,n)⩾1 for all n⩾12N2−10N−2 except for A=A0or A=A1; (b) if R3(A,n)=R3(N∖A,n) for all n⩾2N−1, then R3(A,n)=R3(N∖A,n)⩾1 for all n⩾12N2+2N. Several problems are posed in this paper.
