Let N be the set of all nonnegative integers. For SN and nN, let RS(n) denote the number of solutions of the equation n=s+s, s,sS, s<s. In this paper, we prove that if m and r are two integers with m2 and r0, A and B are two sets with AB=N and AB={r+mk:kN} such that RA(n)=RB(n) for all positive integers n, then r=22l1 and m=22l+11 for some positive integer l. This solves a problem posed by the second author and Lev in 2016.

具有相同表示函数的整数集,II

ñ是所有非负整数的集合。对于小号ñññ,让 [R小号ñ 表示方程的解数 ñ=s+sss小号s<s。在本文中,我们证明[R 是两个整数 2[R0一种 有两套 一种=ñ一种={[R+ķķñ} 这样 [R一种ñ=[Rñ 对于所有正整数 ñ, 然后 [R=22-1个=22+1个-1个 对于一些正整数 。这解决了第二作者和列夫(Lev)在2016年提出的问题。
