Noncommutative maximal inequalities for polynomial ergodic averages

Guixiang Hong, Wenbo Li, Eric Ricard +1

We prove a noncommutative maximal ergodic inequality for averages along polynomial sequences. Let $γ$ be a trace-preserving automorphism of a semifinite von Neumann algebra $(\math…

Schur tests and estimates for positive semigroups on non commutative $L_{p}$

Clément Coine, Mélina Laforge, Éric Ricard

We extend the recent results of Arnold on estimates for Kreiss positive semigroups on $L_{p}$ -spaces to the non commutative setting, $1 < p < \infty$ . We also provide a sharp example. Al…
