On the Gowers Norms of Certain Functions
I. D. Shkredov M. V. Lomonosov Moscow State University
Abstract:
We consider functions $f(x,y)$ whose smallness condition for the rectangular norm implies the smallness of the rectangular norm for $f(x,x+y)$. We also study families of functions with a similar property for the higher Gowers norms. The method of proof is based on a transfer principle for sums between special systems of linear equations.
Keywords:
Gowers norm, rectangular norm, probability measure, probability space, finite Abelian group, Parseval's inequality, Fourier series.
