Title: Revisiting the noncommutative maximal Marcinkiewicz theorem

Abstract: The non-commutative Marcinkiewicz theorem for maximal functions by Junge and Xu is now a fundamental tool for lots of applications (martingales, ergodic averages etc). We tried to get a better understanding of it, and ended up with a rather elementary proof that is almost commutative, and which also provides some small improvements. This is a joint work with L. Cadilhac.
