在Hilbert空间与可分Banach空间关于随机级数的收缩原理

CONTRACTTON PRINCIPLE ABOUT RANDOM SERIES IN HILBERT SPACE AND SEPARABLE BANACH SPACE

在Ｈｉｌｂｅｒｔ空间与可分Ｂａｎａｃｈ空间，用独立随机元收敛准则或三级数定理的思想。

By the criteria of convergence about independent random vectors or that of three series, we prove the contraction principle about random series in Hilbert space and separable Banach space
