Text Let m be an integer with m≥ 2. For A⊆ Z m and n∈ Z m, let R 1 (A, n), R 2 (A, n), R 3 (A, n) denote the number of solutions of the equation a+ a′= n with ordered pairs (a, a′)∈ A× A, unordered pairs (a, a′)∈ A× A (a≠ a′) and unordered pairs (a, a′)∈ A× A, respectively. In this paper, for i∈{1, 2, 3}, we determine all sets A, B⊆ Z m such that R i (A, n)= R i (B, n) for all n∈ Z m when the cardinality of the symmetric difference of A and B is small or large. These extend some previous results. We also pose some problems for further research. Video For a video summary of this paper, please visit https://youtu. be/stBa9Uy5U0I.
