A lower bound on Gowers' FIN_k theorem

Published 7 Oct 2015 in math.LO | (1510.01838v1)

Abstract: Gowers' FIN$_k$ theorem, also called Gowers' pigeonhole principle or Gowers' theorem, is a Ramsey-type theorem. It first occurred in the study of Banach space theory and is a natural generalization of Hindman's theorem. In this short note, we will show that Gowers' FIN$_k$ theorem does not follow from ACA$_0$.
