Suppose that the restricted sumset C = {a + b: a ∈ A, b ∈ B, and a − b 6∈ S} is nonempty and some c ∈ C can be written as a + b with a ∈ A and b ∈ B in at most m ways. We show that if G is torsion-free or elementary abelian then |C| > |A| + |B| − |S| − m. We also prove that |C| > |A| + |B| − 2|S| − m if the torsion subgroup of G is cyclic. In...
