论文摘要
vonWeizsäcker定理指出，非负随机变量的每个序列都有一个子序列，该序列是cesàro收敛到非负随机变量，可能是无限的。本说明的目的是提供对限制有限的集合的描述。为此，由于Brannath和Schachermayer，我们使用分解结果。
The von Weizsäcker theorem states that every sequence of nonnegative random variables has a subsequence which is Cesàro convergent to a nonnegative random variable which might be infinite. The goal of this note is to provide a description of the set where the limit is finite. For this purpose, we use a decomposition result due to Brannath and Schachermayer.
