Abstract

Let G be an abelian group of bounded exponent and A ⊆ G. We show that if the collection of translates of A has VC dimension at most d, then for every ε > 0 there is a subgroup H of G of index at most ε-d-o(1) such that one can add or delete at most ejGj elements to/from A to make it a union of H-cosets. We also establish a removal lemma with polynomial bounds, with applications to property testing, for induced bipartite patterns in a finite abelian group with bounded exponent
