随机级数sum（ξ_nu_n）from n=1 to ∞的收缩原理
Contraction Principle of the Random Series sum（ξ_nu_n）from n=1 to ∞
摘要
Abstract
The properties of the random series sum（±u_n）from n=1 to ∞ is studied,the supremum principle is one of the properties,which can deduce the contraction principle.We find that the random series sum（ξ_nu_n）from n=1 to ∞ also has the similar properties.In the end,the contraction principle can also be deduced by the supremum principle,which is the property of the random series sum（ξ_nu_n）from n=1 to ∞.关键词
