Abstract

It is shown that if VFpn××n is a subspace of d-tensors with dimension at least tnd1, then there is a subspace WV of dimension at least t/(dr)1 whose nonzero elements all have analytic rank Ωd,p(r). As an application, we generalize a result of Altman on Szemerédi’s theorem with random differences.
