非交换鞅的条件平方函数

Conditioned square functions for noncommutative martingales

Narcisse Randrianantoanina

摘要:

在与有限von Neumann代数相关的非交换$L^p$ -空间中,证明了一个涉及鞅平方函数条件形式的弱型(1,1)不等式.作为应用,我们确定了[Ann. Probab. 31(2003)948- 995]。我们还讨论了非交换序独立算子和的BMO-范数。

英文摘要:

We prove a weak-type (1, 1) inequality involving conditioned versions of square functions for martingales in noncommutative $L^p$-spaces associated with finite von Neumann algebras. As application, we determine the optimal orders for the best constants in the noncommutative Burkholder/Rosenthal inequalities from [Ann. Probab. 31 (2003) 948--995]. We also discuss BMO-norms of sums of noncommuting order-independent operators.
