摘要
本文证明了Banach空间值鞅的一些不等式,讨论了Banach空间的凸件及光滑性与某些鞅不等式的联系,给出了Hilbert空间的一个鞅不等式刻划,同时还讨论了一致p光滑空间中鞅的弱大数定律,本文的结论推广与改进了很多熟知的定理。
In this paper we prove some Banach space valued martjngale Inequalitiesand study tbe relationship between these inequalities and the geometry of a realBanach space B(as manifested in its p-smoothness or q-convexity).In the otherdirection a characterization of Hilbert spaces is give in terms of a Banachspace valued martingale inequality and the weak law of large numbers for ma-rtjngales with values in p-uniform smooth spaces is discussed
