摘要
本文运用 Ｋｒｏｎｅｃｋｅｒ引理的推广形式对取值于 Ｂａｎａｃｈ空间 Ｂ上的 Ｂ值 Ｌ’极限鞅Ｘ＝（Ｘｎ，Ｆｎ）ｎ≥０，关于实值可预报序列 Ｖ＝（Ｖｎ，Ｆｎ）ｎ≥１的鞅变换Ｙ＝Ｆｎ）ｎ≥１的Ｌ＇收敛性进行讨论，获得一些有益的结论．
In this paper, we give an extension of Kronecker Lemma in Banach spaced B, and there by discuss the Lp convergence of the martingale transform Y = Fn)n≥1,here X= (Xn,Fn)n≥0, is a B- valued L' limit martingale and V = (Vn,Fn)n≥1 is a real-valued predictable sequence.
