Abstract

Let GG be an abelian group of bounded exponent and AGA \subseteq G. We show that if the collection of translates of AA has VC dimension at most dd, then for every ϵ>0\epsilon>0 there is a subgroup HH of GG of index at most ϵdo(1)\epsilon^{-d-o(1)} such that one can add or delete at most ϵG\epsilon|G| elements to/from AA to make it a union of HH-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.
