摘要
设(Tk,k∈P)为一列具有Δ性质的算子,本文运用鞅方法考虑了部分和序列{∑nk=1Tkf}的Lp范数收敛性,得到了一些充分条件,所得结果对于研究鞅变换的收敛性问题是很有用的。
Let(Tk,k∈P)be a series of operators with property Δ,the methods of martingale are applied to consider Lp-norm convergence of a kind of partial sum sequences{nk=1Tk,f}.Some sufficient conditions are obtained.The results obtained is useful in studying convergence of martingale transform.
