Abstract:

The norms introduced by Gowers in 2001 in his proof of Szemer├ędi's Theorem appear to have an important role in some parts of combinatorial number theory (see the recent works of Green and Tao). The semi-norms introduced independently by Kra and myself in the resolution of a problem in ergodic theory appear surprisingly close. I present these two objects and discuss the light that each one brings to the other.
