Abstract
We show that a real bounded sequence is Cesàro convergent to if and only if the sequence of averages with indices in converges to for all . If, in addition, the sequence is nonnegative, then it is Cesàro convergent to 0 if and only if the same condition holds for some .

Cesàro收敛的特征
摘要
我们展示了一个真实的有界序列 塞萨罗收敛于 当且仅当带有索引的平均值序列 收敛到 对所有人 . 此外,如果序列 是非负的,则当且仅当某些条件相同时,它才是Cesàro收敛到0 .
