摘要
斯里尼瓦萨·拉马努金在[Trans. Cambridge Phillos. Soc, 22(13):259-276,1918]中给出了某些算术函数用指数和 表示的级数展开。在此,我们给出用E. Cohen在[Duke Mathematical Journal, 16(85-90):2, 1949]中定义的Cohen-拉马努金和 表示的类似类型展开。我们还提供了此类展开存在的一些必要和充分条件。

The techniques which we adopted here can be used to derive infinite series expansions of some arithmetical functions using some other generalizations of Ramanujan sum
