报告摘要:Motivated by recent progress made for martingale inequalities in the context noncommutative $L_p$-spaces, more and more attention has been paid to exploring possible extensions of martingale inequalities for more general function spaces (such as noncommutative Lorentz spaces, noncommutative Orlicz spaces, symmetric Banach operator spaces, etc). A common feature of studying martingale inequalities in the spaces mentioned above is that one may often avoid having to deal with the distribution functions of measurable operators in question. We, therefore, directely establish distributional estimates for noncommutative martingales. Our results include distributional versions of the noncommutative Stein, dual Doob, martingale transform and Burkholder-Gundy inequalities. Most current martingale inequalities can be infferd from these distrubutional inequalities easily. Moreover, as an application, we also obtain some new martingale inequalities in symmetric quasi-Banach operator spaces and some interesting endpoint estimates. Our proof relies upon new and powerful extrapolation theorems, which are of independent interest.
