Doob's inequality for non-commutative martingales

Marius Junge
- 19 Jul 2002 - 
TL;DR: In this paper, the authors obtained a version of Doob's maximal inequality for the non-commutative case, which is due to Burkholder, Davis and Gundy.

Noncommutative maximal ergodic theorems

TL;DR: In this article, the authors prove the non-commutative analogue of the classical Dunford-Schwartz maximal ergodic inequality for positive contractions on and the analogue of Stein's maximal inequality for symmetric positive contracts.

Martingales in Banach Spaces

TL;DR: In this article, the authors consider the strong p-variation of martingales in non-commutative LP * and show that it is uniformly convex and super-reflexive.

Non-Commutative Martingale Transforms

TL;DR: In this article, it was shown that non-commutative martingale transforms are of weak type (1,1) and the optimal order of the unconditional Martingale differences (UMD)-constants of the Schatten class S p when p→∞.
