The paper does some discussions on the characteristic which the bounded variation sequence has . ft is found that the monotone sequence is colsely related to it , and very similar with the bounded variation functions , and reach the conclusion as follows : the class of bounded sequence ? the class of convergencal sequence ? the bounded variation sequence ? the hounded monotone sequence 本文主要對囿變數(shù)列的特征作一些探討,我們發(fā)現(xiàn);它與單調(diào)數(shù)列關(guān)系密切,而且與有界變差函數(shù)十分類似,并得出如下關(guān)系;有界數(shù)列類?收斂數(shù)列類?囿變數(shù)列?單調(diào)有界數(shù)列。
